Anyone have update on this or lawsuit? Who do we contact? Help. PLEASE

Sadly, I get to join the club. My 2010 Traverse, which we purchased brand new, had the engine light go on & off intermittently over the past few months. I brought it in to our Chevy dealership and was told the entire timing chain system has to be replaced, which involves taking the engine out. OH, and by the way, your water pump is leaking as well and has to be replaced. The charge just for the timing chain job is $2,800. The car has about 79,000 miles on it but is out of warranty since we are past 5 years (the powertrain warranty is 5 years/ 100,000 miles). How do I find information about a class action law suit?

this happened to my wife’s Traverse at 103,000 miles. after two weeks the timing chain tensioner failed and the whole engine had to be pulled and a new tensioner put in. Luckily I have a great mechanic and he did not charge me a penny. 6 months later and the tensioner goes out again. again my mechanic is repairing on his nickle, but he now suspects it has something to do with insufficient oil pressure, although we have never had a oil light come on. Anyone else had something similar happen?


2010 chevy traverse lt same problem103000 miles…help please…..


We are at 106k miles and we’re told by chevy dealership that the timing chain has stretched and needs to be replaced and also the camshaft we were told it would cost between $3000 to $9000 to repair of coarse our warranty is out at 1000k. We bought our chevy traverse 09 at 500 miles (new) and upon research of the vehicle report it was discovered that the timing chain and camshaft was replaced at 61k and also again at 81k this cost was covered by the extra warranty we purchased when we contacted steward Chevrolet there excuse was we did not change the oil every 3k miles. We were never notified of this after the first or second timing chain repair we were still going by the oil life monitor.
We were not notified that the timing chain and cam shaft were previously repaired nor was the oil life monitorever adjusted by chevy since we purchased the traverse. the oil light has never came up as I never let it go below 25%life
GM and The dealership Chevrolet are both washing there hands of this huge issue that they are aware and no have no regard for our safety.
This will be the fourth timing chain . I don’t know what to do at this stage
Please include us in a class action suit we have all our documentation


This is very disheartening. My 2010 chevy traverse started to have issues less than a year after I got it. I got it used June 2015 and between 75,000 and 85,000 miles i started to notice issues. My check engine light would come on and I’d take it in only to notice it would be off again. Diagnostic after diagnostic Chevy couldn’t figure it out. When they were finally able to check the computer for the codes (when the check engine light stayed on) they told me it was my timing belt. It was going to be 5,000 plus just to fix it. GMC didn’t cover it and the man I spoke to told be exactly what everyone else has started. GMC knows there is an issue but refuses to fix it because the issue hasnt caused a death. I can’t understand why GMC would want someone to die in order to recall the timing! I am fixing to call GMC directly tomorrow. Fingers crossed they do what is right.

Is there a lawsuit? Same problem with our 2010 traverse with 29,000 miles!!!! We are 2 weeks out of warranty and GM refuses to pay anything! With so many people having the EXACT same problem, it says to me that it’s a terrible design. If anyone has info on a lawsuit or a contact at GM that will help out please reply, thanks


I have a 2010 Chevrolet Traverse and it has been a nightmare. My vehicle is out of warranty so I contacted Chevy and they covered 1/2 of the cost. Sounds great right ? WRONG after 2 weeks later the same problem came back. So I returned The car to the dealership and for the second time repaired the car. Now here I am 6 months later and the check engine lights back on with the same codes as in the very beginning.Im at lost with what to do? It seems their is a huge problem with Chevy .Is there anything that us as the consumer can do ? Even though they cover 1/2 the cost it still ran me upwards of $2000.00 .And the issue is still not corrected.

2010 traverse no CEL same problem junk engine timing what you want to call it 108k engine just locked up while on vacation prior to this we had truck@ dealer with under 100k for other recalls rear hatch door,seat belts, steering and mentioned weird engine noise now I’ve been a mechanic 15 years and never heard any engine sound like this they told me its all good and said it was a high pressure fuel solenoid on DI it has to mantain over 1500 psi that is what you hear so i believed them I stressed to them it sounded to me like oil was not circulating in the engine under the right pressure cause cold start up was even worst noise than what the running engine sounded like. Anyway they would not cover it either way so we torn it down. Nothing would turn even with the chains removed from the engine. From bottom to top bad engine or no oil circulating. By the way I always use Mobil 1 Ext Performance Dexos and K&N filter
Religiously and check my oil on all of our vehicles once a week.Since when do we manufacture engines with timing chains that fall under routine maintenance any engine with a chain for timing is meant to last the life of the engine period look that up. Why do honda and toyota timing BELTS last longer than chevy chains no joke there it’s a fact .Please stick with Honda or Toyota nothing comes even close to engine quality US auto makers need to learn how to make a VVT engine form Japan.


My 2010 Acadia is in the shop right now for theexample exact same thing. Stretch timing chain. Quoted 3100 to repair


2012 traverse same issue 113k miles on it.


2009 traverse. 130k miles same deal. How do we file for the lawsuit?


Exact same deal! 2009 Traverse, 130,000 mi. Chevy will not cover it…

So add me to this list….I have a 2010 GMC Acadia with 67K miles and my CEL was going on/off for several weeks. I first took it to Autozone for the free diagnostic report and it gave me the dreaded P0008. I was then going to take it into GMC but it went off for a bit but then yesterday came back on. So I took it in, got the 3K repair bill, and am now trying to comprehend how this defect is not yet being considered a manufacturer recall. It can’t be coincidence that this make/model/year is having this obscure issue at the same time (as the 2009 recall addressed).

I did call Morgan & Morgans per this thread and they took down my info the first time it occured (a few weeks back) but no return-call yet so I’m not holding my breath on that. If anyone gets any info on this being added to the recall repair list for GMC or if you know how to fight this to become a recall, please let me know.


Please contact me and let me know how to join lawsuit.


Me too. I will join. I have a 2010 Traverse 88,412


Please if you find anything out about lawsuit let me know. I have a long history of transmission, timing chain, and crank shaft repairs on my 2010 Traverse. Most recently my valves are misfiring and it’s recommended I don’t fix the car. It would burn oil terribly to the point I’d be way low with routine oil changes. I really did my like my Traverse just frustrated by all the mechanical issues.

My 2010 Traverse has the exact symptoms. CEL going on and off. 3K repair. same issue as 07-09


2009 GMC Acadia 106K miles and NOW I have issues with the timing chains. Of course I’m right over the warranty limit. This is ridiculous!


Hi…is this thread still valid? I have a 2011 Traverse with the same issues. Received a quote of $3600 to repair and I’m under the mileage for warranty..just over on time. I’ve read plenty of threads where this is an issue for many owners, but when I spoke to two different people at GM, they refused to acknowledge that it’s an issue and they won’t help to compensate a portion of the cost. Ridiculous.


I fear mine is the same. 73,609 miles, P0008 code but out of the 5 year portion of the powertrain. Anything ever come of this?


+class action law suits may be in order about timing chain problems with the traverse since 2009 GM should pay at least half the cost for a problem their well aware of. My cost is $3800.00 for my 2011 with only 75k mi


Do you mind if I quote a few of your posts as long as I provide credit and sources back to your weblog? My blog is in the very same niche as yours and my users would truly benefit from a lot of the information you present here. Please let me know if this alright with you. Thank you! aggbdbbbcebkeacc

Yes, that would be fine.


2010 GMC Acadia 71k miles. Timing chain has stretched. We missed the powertrain warranty coverage by a year, so GM declined assistance. But since timing chains should NEVER fail on a well-maintained vehicle, and since this seems to have been a known and prevalent issue since 2007, I called Morgan and Morgan this afternoon to join the class action that other owners are trying to form. (Not to mention, we’ve already racked up thousands of $s in repair costs in only 3 years of ownership.) If you have this issue, please call as well. Tweeting @ThisIsGMC and @GM and posting similar appeals on Facebook couldn’t hurt. The more similarly affected owners we can convince to contact Morgan and Morgan, the more likely that class action is to become a reality. It certainly can’t hurt.


How can I contact Morgan and Morgan?


Is there a class action? My 2009 is sitting in my garage 129,773 miles on it with alot of pricy repairs including the timing, struts, power steering and more. The vehicle acceleration is sticking which is #1 safety issues since it happened with my 8 yr old in the vehicle in rush hour traffic out of the blue! Shame on GM for waiting for a death to do anything with all the reports!!!!

Karen W

Can you please email me the information to contact Morgan and Morgan?

same issues with my 2010 Traverse. Timing Chain stretched. Caused $5000 worth of damage. A week without vehicle and GM and dealership offered NOTHING to help. I called Morgan and Morgan. Hopefully enough of us will call and report it.


Same here on my 2010 Traverse. Timing Chain replaced in 2014, then Timing Chain engine code came on again in Sep 2016. Entire engine had to be replaced. $8K. Requested some help from GM due to the 2009 extension. They said No. I need in on this class action lawsuit. My email is


Can you please forward me the information on how to enroll in the law suit. I have had the same issues!


Would someone send me a number to get on the lawsuit. My timing chain had to be replaced and now camshaft. My email is or text 2562670992


I am having the same issues with mine. I have spoke to Chevy and the refuse to help in anyway. Mine is a 2011. How do I get in on the law suit


I have a 2010 Chevy Traverse & my timing chain has stretched. I thought GM would treat it like the 2009’s & fix it up to 120,000 miles, but they don’t acknowledge this as an issue yet. I will be looking to join a class action suit.


Mike – any info available to get in on this suit?


Mike, the same thing happened to me today. $2250.00. I’m in on the class action suit.


Same thing happened to me how do I get involved in the class action suit
Thank you


I had the same problem with my 2010 Traverse…77777 miles on it and now we have to pay $3800 for repair of the timing chain in addition to being without the car for 2+ weeks. Information regarding how to get involved in the class action lawsuit would be appreciated. Thanks!


Same thing happened to my 2010 Traverse. Can you give me the info to get involved with the class action lawsuit?
Thank you


I have the same problem but my 2009 traverse has 121000 miles. What can I do ?


Have a 09 Saturn Outlook. Bought used from GM dealer. Warranties intact. Not long after purchasing the vehicle, noticed a miss like a bad plug, or coil. Took back to GM dealer here. They checked the vehicle and replaced the coils, or so we were told. Still noticed a miss, but they kept telling us they could not find a issue, or could not “feel the miss” when they drove it. problem would come and go.
About March this year, we had a coil go bad, as in melt, which dumped fuel into the exhaust and burned out our cat converters which were not under warranty anymore.
Long story short, repairs have been coils, camshaft sensor, crankshaft sensor, BOTH cat converters, O2 sensors, TWO computers because the first one was bad. After all this, the vehicle kept throwing codes that read P02 something. “ECM Detects Rich fuel mixture Bank 1” Anyway, took the vehicle to the GM dealer and all they wanted to do was throw in another cat converter to the tune of 900.00. Got a second opinion at another dealer. They suggested that the code and reading was because of a timing chain issue, possible stretched causing unburned fuel to get into the cat converter thus causing the code. The vehicle has 95,600 miles.
So….The dealer where the second opinion was given has done the work under warranty and has replaced the “Power Steering Assist” because we were having a issue with the steering having to be muscled literally to get it to turn under low speed, then suddenly it would catch and be ok. It was replaced under warranty as well.
Has anyone heard of these issues. Will this usually fix it???


I have a 2010 GMC Acadia. At about 77,000 miles the check engine light started coming on and off. One day it would be on the next off and it would go a week or two without coming back on. No issues with driving the car. Still a very smooth ride. Eventually brought it to the mechanic because it was continuing to do the check engine think for a couple months. Now they say I need to replace my timing chain. I have 80,000 miles on my car and its 6 yrs old! This is ridiculous! Now the mechanic says my car isn’t covered under the warranty because its only up to the 2009 models! Has anyone else with a vehicle newer than 2009 had any problems with this?


I have a 2010 Acadia with 75000 miles on it. I am getting ready to replace my timing chain as well. Love my car,but I feel gmail should cover mine as well. It has same parts as the 2009. I would join a lawsuit as well.

My 2010 Acadia has just now experienced the issue — it has 109,000 miles.


Gm is paying for my timing chain on my 2010 traverse 7 days after I got it from dealer


YES! I have a 2011 traverse. Same thing with the engine light coming off and on, finally took to Chevrolet dealer and they said it was the timing chain and would cost est. $2000! We just paid it off recently :-( The only big difference between you and I is that ours has 173,000 miles on it! My husband commuted for 3 years from here to KC ( 4hours one way) He would leave Monday and be home Friday. Now it is my delivery vehicle ( flower shop ) But still, this should not be happening to such a new car!!! I’m so upset and not sure what to do because it is obviously NOT covered under warranty. And you have to ask yourself with knowing what a huge job this is, will it all be put back exactly right and even if so, what else is lurking around the corner for another repair. Last year it was my stable track control system that cost us $800! I miss they days where they could be worked on by a common knowledge mechanic.


Same here! 2010 Acadia with 87,000 miles. Check engine light just started coming on and off, sometimes for a day, then off for several. The most it stayed on was 3 days. It runs smooth, no issues. I took it to our local GMC dealership, they confirmed it was the timing chain. Quoted me $2400 to fix it but after calling GM assistance office they were able to get dealership down to $1900. I still havent had it fixed cause I’m seeing what else I can do. I know this is a manufacturer defect cause it’s to soon for the timing chain to have an issue and seeing everyone with the same issue as me. I’m just mad that I would have to pay this out of my pocket. However they are aware cause the GM rep told me that if this ends up being a recall, I would be reimbursed just to save my receipts. I think the more people that call to report this, the better chance we’ll get this fixed under an extended warranty!!

Karen W

My 2009 GMC Acadia is doing all of the same things.


The 2009 are covered under warranty for the timing chain. They issued an extended warrenty for 2009 Acadia only. Call your local GMC dealership or the GM customer assistance line abs they should be able to help


GMC covered the timing chain replacement on my 2009 Acadia however it has yet to fix my continuing misfiring catalytic converters clogging. I have spent thousands on repairs and make a nice monthly car payment for a vehicle that is not safe and is making an ugly yard ornament. No one will help and I cannot afford to just get another vehicle. Do you have the info I’m seeing on this site about Morgan and morgan


I have a 2009 Acadia and the timing chain needed to be replaced and GM wouldn’t cover it because it was already repaired 15,000 miles previously. I called GM myself and they paid me $990.00 but the total cost to repair it was $3,200.00. I asked them how they come up with that number and they stated because I wasn’t the first owner and it was repaired once before. “Lexi” from customer service stated that she would note the customer wasn’t happy and close out this complaint!
In the recall information on the website it states that GM will cover the cost of the timing chain up to 10 years from the first date it was initially put in service/or up to 120,000 miles in which my car didn’t have 120,000 miles on it and it was only seven years old. How do they think this is O.K? They didn’t say if/and/but they simply stated 10 years from initial date vehicle was put in service for timing chain problem or up to 120,000 miles.
How can I get in on this class action law suit?


Same Here! 2011 Traverse. UGGGG!!!


Yes mine Chevy Traverse is a 2010 and after a hour of buying it my engine light came on so I took it to the shop and it was my timing chain. So your not the only one that experience this problem. :(


So did you buy it used? If so, I’m sure thats why it was for sale. I’m in the delema of being stuck with paying to have it fixed because there’s no way I could look someone in the eye and act like nothing is wrong with it. This should already be a recall. GEEEZ! I hope that you figure out a good solution

Yes I’ve got the same problem and I still owe a lot of money to the bank I don’t know what to do, I’m sick about it. And also my wave plate in the trans. They want 9,000 for repairs what a piece of crap I’ll never buy another gm product again. For now I guess I’ll let it set and continue making payments.


I’m in the same situation with my 2009 traverse. I still owe 9000 on it has been sitting at the dealership shop for about a year . The bank or shop don’t want to do anything to help have been paying for it every since. Do not get a used vehicle from Rizer Chevrolet in Walterboro Sc.


that price is crazy…it is a $2400 job, not 9K


Christine, I have a 2010 GMC Acadia SLT II with 75,640 miles. Code P0008 Engine Time Chain issued. No covered by warranty. All 2009 models are. Fix this now, it can lead to serious engine failure. Cost is $2,000 to $3,000. Call Morgan and Morgan at 877-667-4265 to contribute you horror story for a class action suit. I called them yesterday and started the process. GMC’s customer advocate line is aware time and chain issue however until we stand up to them they will not flex. Thanks, Vince


I called today. Same issue with my 2010 Acadia with 87,000 miles. Check engine light, with P0008 code. Timing chain issue! Not covered.

I called as well.

I’ll be calling tomorrow, thanks.


just had my engine light on my 09 traverse went to dealership to have it check today they said i needed timing chain, i have 104000 miles adviser said chain stretch, oil sludge buildup i call GM cust svr and gave them my vin# he look it up and told me there was a extended warranty issued for my engine 120,000 /10 yrs great news gm knows issue with premature were and tear on timing chain due to oil monitor system less oil changes thinner timing chain used in 2009 models , they did recall and adjust monitor system to have more oil changes in 2011, even know i change my oil every 3000 miles never trusted that monitor system,


Hi folks, please call Morgan and Morgan to report this case, I have reported this for the potential for a class action suit. GMC,CHEV have a known problem per their consumer advocate line, I called today. However they will not own this mistake due to their internal research. It took 5 minutes to report this. Morgan & Morgans # is 877-667-4265.


Everyone on here NEEDS to go to and file a complaint. That is the only way something will get resolved. I just filed a complaint because my 2011 traverse with 40,000 miles needs the timing chain fixed and has check engine light on with codes P0017 and P0008. This is not fun to pay for and something needs to be done! There are way too many people having the same problems!!!


Sorry it’s my autocorrect removed the R!


Hi my 2009 Chevy Travese with 105,000 was fully covered for the Timing Chain repair by my Chevy dealership. Just got it back last week from the shop and it seems to be running like brand new. I guess there was a recall that fully covers the Timing Chains repair for 10 Years and up to 120,000 miles . I had no warranty left on mine so I’m glad for that recall. My regular mechanic told me to just Go to your GM Chevy dealer and have them look at it and the check engine light told them it was needed and they covered it all. So hopefully you too will be fully covered and feel as lucky as I do.


They told me it wasn’t a recall

I have a 2009 traverse and we are in the same boat however our gm dealership is not willing to help unless we pay $600 tear down time. Did you have to pay this?


Hi Liz, No I didn’t pay any thing for mine. no tear down fees or installation costs etc. But maybe it was because I was the original owner and had kept up on all the recalls and brought it back to the dealer I bought it from when it was new…. I dn’t know. There is a campaign on this not sure what that means in relation to na recall but mine was fully covered.


Liz Being yours is also a 2009 traverse (like mine) it should be covered by the campaign. They might have told me that there could be a fee for looking at (you know the usual $75 to look at it and we’ll put it toward the repair) anyhow in the end it was fully covered and I paid no costs for them to look at it or repair it . Maybe you need to call an arbitrator at Chevy Head quarters?? Not sure how you do this but Ive heard tell of such things, maybe they are available on-line. Maybe consider having them do it and then petition a Chevy arbitrator to get the 600 paid back, or try another Chevy dealer, Not sure What else are your options if the repair costs $2000-3000 and the car is broke ??


Well no recall on the 2011 and I have to foot the bill even though gm motors knows it’s a problem on the traverse. So I now have no car and a huge bill.i will never buy a Chevy vehicle again.

I agree Nina, I have a 2010 traverse it’s down with the same situation


Can someone tell me what if my 2010 Traverse has a special 120,000 mile Warranty and if so, where can I find the paperwork on it so that I can take it to my dealer?

GM told me no warranty on the 2010, only the 2009 not sure if they are full of crap or not wanted to charge me thousands to fix

I took my 2011 Traverse with 64K miles to the dealer on 4/22/16 because while I was driving and coming up on a red light, my whole care started shaking, my brake pedal was jumping under my foot, my rpm’s were going sky high but at the same time jumping and my dash lights were flashing to check engine. I had my three children in the care, I was really scared, then suddenly it just stopped. It was really silent and I thought it was dead but then I was able to drive it 2 miles down the road to the dealership. I waited in the waiting room while they looked it over and then they told me there was nothing wrong with it,. They said someone must have sold me bad watered down gas or something. I told them I was scared to get on the highway with my three children to go back home but they said it was fine. I don’t normally drive much working 2 miles from home but when my husbands work truck was in the shop, he needed to borrow my car for work and he drives most of the day. So 10 weeks later, at 67K miles, after he had been driving the care more, it started to make a noise, he checked the engine, all the fluids, everything seemed fine, he put an extra court of oil in it to be safe and called the service at the dealership immediately. They told him to bring it down and he would take a look at it. We live 25 miles north of the dealership and to get there you have to get on the highway. My husband said it sounded a little better but before he got on the highway, the engine, the… Read more »

This is the exact same thing that my car has been doing. It would shake real hard, say reduced engine power, then a few minutes later, it would be fine. I even got a letter in the mail about it. Took it to Ron Craft Chevrolet and they said that there was nothing wrong with it. Ughhhhh!!!!


Heather – Where did you see the bulletin that GM said not to repair the engine on a 2011 traverse. I am out of warranty also and have an engine issue. Please reply


Check, manufacturers comments, specify engine to narrow your search, there is a link to click where you can download the service bulletins on the vehicle!
I don’t know what your specific engine issue is but I do know this…the oil life monitors allow extended times between oil changes in a vehicle with a flawed engine that consumes too much oil. buildup causes less oil to get to vital engine components (I’m not a mechanic, just reading and putting pieces together). The timing chain, also flawed, stretches and may lead to signs of engine running rough or out of time. Sometimes displayed as a cam sensor issue but underlying problem is the timing chain. If not caught early and replaced, you may progress to engine failure as I did. This engine is designed poorly and despite replacing components it will inevitably fail again. Increasing oil changes may prolong failure but not prevent failure. My advice to you is get rid of this vehicle while your engine is still alive, If it’s still alive.
I told my coworker 3 weeks ago to get rid of her vehicle NOW, same year, same engine, same miles as mine. She was going to but was working a lot and didn’t have time to car shop, her engine failed on the way to work last week!

Get rid of this vehicle now or as soon s it runs, you will be sorry you waited another minute if you don’t! I am sorry you are going through this! I have cried for weeks and now I have just accepted the facts and am trying to figure out what to do as my car still sits at the dealer needing a new engine!


Heather! Thanks for the info I agree with you.i have to have mine fixed the mechanic is hopeful it’s the timing Chana about $2200. Have to flat bed the car their in two weeks told me do not drive it at all.after he takes it apart he will be able to see if it is only that. Then I will trade it in.thinking never buy a checy gm vehicle again.they don’t care .they know it’s still a problem since 2009 but won’t extend the warranty on the 2011 engines. Makes me sick to think how much these cars cost us and how much money they make .


Heather if your initial report of your problem was prior to the expiration date than you should be covered. A week later and now you’re not covered isn’t correct. Not matter what they told you initially was the problem, obviously they were wrong.If you persist and make a lot of noise they’ll have to do something. Contact all you have to: Service Manager, Owner (Dealership), Warrenty company,etc. Not sure if you’ve had it repaired at this time but you may be owed a refund. I’m now faced with a timing cover leak and no warranty, OUCH. 2011 Chevy Traverse 120,000+ miles.Best wishes.


I recently took my 2010 Acadia to someone because my check engine light was on, having other issues as well, like a vibration at times, no power up hills, seems like it is having problems shifting when gas is pushed, etc. (not good with descriptions) After he hooked it up he told me it was the timing chain and it was stretched. I have 160,000 on it. My question, who do intake it to so it can be fixed? How expensive is this? Thank you!


We are repairing mine now. Take it ASAP to a mechanic. We waited to long and ended up having to have the heads replaced as well as the timing chains!! The tensioner gets loose/stuck and let’s the chain slip. It’s a huge mess!!


Thank you for your response. It is currently in the shop. I hope I didn’t wait to long. It’s a mess.


This fix is going to run you around 2000.00


I was told about $2,500.00. I hope it’s closer to $2,000.00. Thank you for your response.

Can I upgrade my 2009 traverse engine to a 2014 traverse engine ?

2010 GMC Acadia possible timing chain stretch issue. Purchased vehicle used 2 yrs ago now have 96K miles on it. Yesterday car wouldn’t start after being drive 10 minutes earlier. Pulled codes and all pointed to the 1,3, and 5 cylinder ignition issue. Cleared codes and seemed to be fine, drove 20 miles with deep resonate sound at cruise that went away when accelerating and decelerating. Drive back home sound remained the same and check engine light came back on. Pulled codes once again and different set came up with P0008, P0016, and P0017 signifying timing issues which makes me believe timing chain stretch. I think I might be in for an expensive fix but most I want this reported to manufacturer to maybe be the last straw to include my year vehicle recall. Any info would be appreciated.


Having codes showing that my 2010 Acadia needs timing chain replaced. However the car is showing no systems, such as rough idling. Should I continue using it and if so would it possibly cause further damage?


You keep driving it, and the engine will be distorted. Fix it now, it will cost around 2000.00


Same here with out 09 traverse. Been a lemon from the start!! The timing chain and transmission has been changed in the past year and a half under warranty. Now the timing chain is “stretched” again….to the tune of $2100. We have 125k miles so not under the 120k warranty. GM is offering to pay $600. We are still paying monthly for the POS. Weighing options now to trade in or not. It sucks that I can go buy a 2012 traverse and be fine….just 4 or 5 more years of payments :(

Can anybody tell me if its worth getting this fixed or am I just wasting money and it will break again soon? Wouldn’t mind fixing it if it will last.


Somebody out there needs to bring a lawyer on board.

Hello Everyone

I’m having the same problem right now my 09 traverse has been sitting at there lot since 5/01/2016 they replace the timing chains , power steering pump, water pump an updated software an my transmission is running rough idle is way to high around 2,000 rpm car complete shut off on highway scared the crap out of my wife an kids . By the way this happened on Mother’s Day broke down on Sunday . Took it back the following Monday got a phone call from the service advisor my pistons are knocking need a new engine WTF!!! an it’s now 5/26/2016 an still no answer from GM all there saying is I have to pay out of pocket B/S they have to be responsible since they change the timing an mayb set the timing wrong or didn’t change the actuators . Idk I’m not a professional . But yet service advisors are pushing me to pay a engine tear down fee of $500 why idk when the tech’s have confirmed my Pistons are knocking hello moron it needs a new engine Pistons are knocking . I feel GM doesn’t really care of there customers safety . Do you have an update an what’s going on ???? 140,000


My dealer wants 1K for a tear down (10 hours of labor) to determine the cause of my engine failure in my 2011 Traverse with 67,000 miles. They know what is wrong, they received numerous bulletins about this engine. These bulletins are available on the National Highway Traffic Safety site
I will never be so quick to buy a car or trust a salesman, dealer or service technician for a dealer again! I do not know how they sleep at night making money off of endangering families!


We paid $$$ for new timing chain on our 2009 Enclave. That was 30,000 miles ago. Guess what? We need it again. White Bear Superstore said last time they didn’t change the actuators because it didn’t pull that code. Bad actuators means new chain at about $2800. Low oil level was partly to blame. This was a lemon from the start.



Which piston needs to be on tdc to install first chain

Susan Untermeyer

I do NOT think GM has solved this issue at all. I have a 2011 Traverse and my timing chain is just about to break, or stop working, any day. I have talked to GM because my car has the EXACT same issues as the model years before had but they told me “sorry we can not offer any help”. I have always had Nissans before this car and I will go back when I get this one paid off. All my Nissans had over 200,000 miles and nothing but regular maintance. Its really sad the US can’t make a good car.

Yep same issue with my 2011. Going to foreign cars I have had it with this .GM dosent care even though they know the engines are bad

2009 Traverse
My 2009 Traverse has approx. 140K I took it to the dealer because the engine warning light came on along with other messages such as “Service Stabilitrak”, “Service Traction Control”, and “Service Brake System”. I was most concerned with the Service Brake System message so I took it on Wednesday, 4/27/2016. Today is Friday, 4/29/16 and received a phone call from the service advisor that the timing chain must be replaced to the tune of $5K. WTF? The special extended warranty ended at 120K miles and now it can be replaced free of charge. I put in a call to GM Customer Service to see what they could do because it’s still under the 10 years period. What is this business of 120 miles or 10 years, whichever comes first? Sounds like a scam to me.


2013 Acadia with 36k miles, all chains need replacing. Was driving 50mph on busy city highway when I lost all power, power steering, and brakes felt hard. Safely pulled to right lane, no shoulder. Only warning I had was a quick flash on the dash that said service charging system. I bought used in January and just did my second oil change since purchase even though I have only put 2400 miles on it. Check engine light didn’t come on until after the stall. Very scary experience. So here I am without a vehicle for a week while it’s being repaired.


That might be an issue with your throttle valve. Had exactly the same situation with my 2011 Traverse. Was about $500 to repair, but GM issued a recall on this issue late last year, so I was reimbursed for the repairs.

2010 Acadia
2010 Acadia owner here – many reliability issues but nothing as problematic as the timing chains (P0008 / P0017). I have been meticulous with its maintenance throughout ownership, with no oil changes exceeding 5000 miles; yet this $50,000+ vehicle is heading for its second set of chains with only 130,000 miles. First set under warranty but not so fortunate this time around. I pursued this tenaciously, but ultimately my arguments were unheeded by GM’s management and Customer Service minions. What a debacle this is, not only for me, but for all loyal GM customers. The 3.6L engine design was clearly flawed from inception, with the direct injection version released in 2009 proof of another engineering failure as these engines succomb to stifling carbon builup on the intake valves. Ultimately, it robs you of performance and reliability and then attacks your wallet. As me how I know – I just finished walnut blasting all 16 intake valves to remove this cancer. In my 35+ years of owning and turning wrenches on GM products, never before have I seen a more problem ridden platform (Acadia, Traverse, Enclave or anything else equipped with this 3.6 engine). Not looking forward to replacing the timing chains myself, but a necessary evil to avoid a $2500 – $3000 dealer repair bill. I’m fortunate that I can do it, but my heart goes out to those that are blindsided by this repair. It’s not – IF it happens to you; but rather, WHEN it happens to you. The design makes it inevitable. Remember, only 2007’s and 2009’s are warrantied by the current GM Special Coverage Adjustment. Other model years are widely impacted, but GM has taken specific and calculated measures to limit their corporate liability. Quite a strategic maneuver on the part of GM – admit to… Read more »

Thank You for verifying everything that I have researched and have come to discover as I have been paying on a 5 year old Traverse with 67,000 miles that doesn’t run because the dealer said I need a new engine and I cannot afford a new engine and still owe $18,5 on the car. This has been a horrific experience. I though someone would help since my warranty expired 9 weeks before the failure and because I was already at the dealer before my warranty expired complaining of something wrong with the engine. I came to find out this was a known problem and I was told it must have been bad watered down gas before the failure to be pushed out the door and drive this vehicle with my children when they knew it was my engine. I was there 4/22/16, my warranty I find out later expired 4/28/16 and now I need a whole new engine and nobody will help me as I pay for a vehicle that doesn’t run and sits at the dealership until I can come up with the 1K engine tear down fee to even diagnose the problem and then MAYBE GM might help me but I will still be paying at least $4,500. of the re-manufactured engine price of $6,300.
I am devastated, I have been crying for weeks and nobody will help me and so it sits there while I pay $500/mo. car payments on a car I cannot afford to repair and if I stop paying to save the money for repair, the bank takes it and I am out 18,5 plus fees and will ruin my credit from obtaining a car in the future.


Master Tech, any chance you could share the info about repairing the timing chains in the 3.6 chevy traverse? what is the difference in the updated parts? do i need to get them from the dealer or any auto parts store will have them available?
i would really appreciate you sharing this info.
Thanks in advance for your help.


I nees to do it myself also do u have any info on all the torques? Any j fo would help i will continue to search the net

Master tech with Chevrolet

Hello Marc if you send me your e-mail I can send you the info you need. Also FYI the chains can be done with the engine in or out of the vehicle.


Could you send me the same info on replacing the timing chains on my 2010 traverse. Can they be changed without pulling the engine? Thanks in advance.


can you send the info to me


Could you please send to me as well. Thanks


Master tech I have a 2011 traverse that needs the timing chain changed. Can you send the instructions to please and thanks


Master Tech, please can you send me the instructions of replacing timing chains with engine in vehicle. Looks like I have the same issues.
Much appreciated.


Master tech, would you please send me the instructions on how to replace the timing chains with the engine in the vehicle? Thank you so much in advance!!


Hello Master tech,

I have a 2010 Traverse LT that I do intend to change the timing chains. Could you please email me at smfunk69@ with any pointers from all parts to replacement of parts while in vehicle. PLEASE.

Thank you for your knowledge and comments. God bless.

Master Tech could you send me info to change chains in 2010 Traverse


Master tech, interested to see if you are able to send info about how to go about replacing timing chains in an 08 acadia with the engine still in the vehicle…. my email is XXX


Hey master tech. My wifes Traverse has been sitting in the driveway with the same issue and have debated doing the work myself. However, getting it lifted to remove the engine is quite an issue. I would love to see your repair procedure. my email is XXX


Hi Paul master tech or Kerry could you please send me those specs too I am in the same boat to and it’s sinking much appreciated if you could email is XXXXX thank you paul


Master tech,

Can you send me the info too? I’m thinking I’m about to have to do this to my mom’s 2010 Traverse.


I have a 2011 traverse with check engine light on. Code says engine position system performance bank 1. Everything I’m reading suggests that is a time and chain issue. However I am not experiencing any vehicle problems. In fact the vehicle runs great and that’s with 114k miles on it. Could be something else that is linked to the time and chain?

i just took my 2012 traverse to the dealer with a check engine light on . well it was the timeing chain. i had a power train warranty and know they tell me that its not covered because they are saying i did’nt change my oil correctly. then the rep continues to say that my traverse will use 1 quart of oil every 2000 miles. so if you dont change your oil but every 5000 you will be 2/12 quarts low before you have to change it. we were not notiifed at the time we bought the car and know they want to replace the engine for $7100.00 which i dont have so who is tio blame .beware if you have a traverse because this will happen to you and if anyone can help me i would appreciate it


This is a known problem, they are blaming the consumer for their flawed engine. I hope that you received some help and if you did please let me know. I cannot get any help on my 2011 Traverse with 67,000 miles that needs a new engine, they wont do anything until i pay 1K tear down fee to determine the cause of the failure but say despite that they know I will need a new engine so it would be wise just to pay for an engine swap $6300. for a re-manufactured engine. I still owe 18,5 and my car that sits on the lot at the dealer were it was towed weeks ago.

Same thing happened to us on our 2009 traverse Ltz!! GM should be ashamed of these vehicles that cost a huge amount of money in the first place. I now understand why a lot of GM plants have shut down. We will never purchase another GM! They obviously know this is a huge problem and are willing to do nothing about it.


Same thing on my 2010. Timing chain diagnosed wrong now had to put a new engine engine in it. Will never buy gm again

Texas Dean

Watch out if you’re buying a used GMC Acadia. I bought a 2007 Acadia, which checked out clean on CarFax and showed only routine repair in GM dealership computers. Within a few months, a warning light comes on and it shows a timing chain problem. Dealership says GM has known about this defect in their design for years, putting a ‘special policy’ in place to pay for repairs before 120,000 miles. Since I bought the car used, I never heard a word about this. GM sent a bunch of propaganda, as they do with all car buyers but never told me the car would likely quit running soon because of the defect they knew about. Now the car has stopped running, with dealerships saying repair will cost north of $3,000. I call GM’s customer service brigade and supervisor says the “final answer” is that GM won’t pay a dime to repair this problem they caused. They’re fine for all of us to buy their cars, with all the defects they are keeping secret, and then leave us stranded. Bottom line: They issued a ‘special policy’ to repair it, but didn’t tell this owner. Then, when the car quits after an arbitrary 120,000 mile mark, they’re fine to have us making monthly payments for cars that don’t run. They claim it’s like exceeding a warranty period. But shouldn’t it be different if it’s a defect that they covered up? I feel a lawsuit coming on, just to force GM to do the right thing.


I got one for you…… I own 2012 Acadia, took the vehicle in because the warning said low oil pressure. Now I have only had the car one year and I did 4 oil changes in that year. The service department that I took it to said engine sludge was the problem and they were not going to fix it. The wanted me to pay $4,000 for sludge removal. Of course upset and very angry about this, I had my vehicle towed home. However not being the ignorant female they thought I was . I asked for a printout of the diagnostic codes, did some research and sent the car to another dealership who says “it’s not sludge, your timing chains are bad”.meanwhie I’m out nearly a thousand dollars on rentals and seven hundred on a breakdown of the engine for a misdiagnosis. Yeah lawsuit sounds about right!


How did everything turn out? Did you get any help? I can’t get anyone to help me and need advice. I have the same engine in my 2011 Traverse with 67,000 miles. The engine “locked up” while driving and they are telling me I need a new engine. I now know of the issues with this engine so the dealers must know too. Service bulletins from GM to the dealers can be found on and after you put your vehicle information in go under manufacturers comments and click the link that downloads the service bulletins. They knew for years about these problems and this engine is used in numerous years and makes. I never realized till now that my husbands 2010 camaro had the same engine and it had to be replaced at 38,000 miles. There is an inherent flaw with this engine and many people haven’t spoken up because it happened during their warranty period and therefore was covered (like my husbands) but for those of us that they say sorry, your out of luck, your warranty expired or we are going to blame it on something you did or didn’t do to get out of taking any responsibility for it, we are the ones suffering and paying GM big $$$ for them to turn around and make us pay more and more on a vehicle that is with certainty will have premature engine failure.

I feel GM doesn’t really care of there customers safety . Do you have an update an what’s going on ????


Your story sounds very similar to my own, did you have any luck? I don’t know what to do. I have a 2011 Traverse with 67,000 miles on it that needs a new engine and I cannot afford the 1k teardown fee that my dealer requires to determine the cause and then the cost of a new engine because my warranty expired 9 weeks previous. I complained of the engine surging and the rpm’s sky high and the car shaking during my warranty period and was told the gas station must have sold me watered down gas because nothing was wrong with my car. Now my warranty is expired and nobody will help me. I owe 18,5 on my car still and it has been sitting for weeks as I cant afford to repair it.

My check engine light came on about 95K. I now have 110K. will GM still replace this for me.

Chevy can’t find problem with 2010 Chevy traverse radio no sound


My 2010 Acadia did this, and it also would play the radio when the car was off and doors were shut, basically when I wasn’t in the car! It was a computer issue but all they told me was that there was a “grimlin” in my dash. No reall explanation. I would look it up on my vehicles repair record on the GM website…but guess what…for some reason my 19 repairs over one year done by the GM certified dealership won’t show up on the customer side of their website…hmmmm.


Is there a recall concerning timing chains for a 2010 Traverse?


There should be cause my 2010 traverse is in the shop right now and needs a new timing chain. Running around $3K. This is horrible to buy a truck within a year and need all this work. I took it in 6 months ago because of the steering wheel. Urgg

If the timining chain brakes on the Chevy traverse will the cams hit the values in the motor or is this the type of car that don’t hit the values .?


Would anyone know? I have a check engine light code p000d. have anything to do with the selenoid, that is what the dealer is telling me but when I look online it sates it is related to the chiming chain. my car is a 2009 Saturn Outlook

Markquill suggs

I have Chevy traverse 2010. I bought this truck with 24 thousand miles on it, by the second month. My check engine light was piping on and going off. I took in, they check it said it was nothing. But auto zone gave me tickets when they check it. Codes p8000. Camshaft/timing chains. Well they checked out. Light went off. I drove it . A year later light came back on. Bobbrockman fixed it ,August 2013. Keep the vehicle for 5 days. A year and one month October 2014. The light came back on, and now they want me to pay for it!……2,200 . So I called the better business bureau. Filed a case with them. I had to pay 1000, down before they start on my vehicle, then they comes with this ! About lack of oil changes is the reason I need a new Timing chains. Lack of maintenance cause these. I had proof of my oil I filed a case because they called me and said I still owe thousand and fourty dollars to get it fixed. I pick it up and now my air conditioning is out. Bobbrockman dealer ship is rip off, along with these General Motors. I have replaced two timing chains before 100k miles., powersteerng system, wheel bearings, rotors and air conditioning system looks like tomorrow. I will be going to the news telling my story and how the dealer got over on me. Iam not paying another dime on this vehicle it was a piece of crap! From the beginning.


Did you have any luck? I am going to have to file complaints too! I owe 18,5 to the bank on a 2011 Traverse with 67,000 miles and need a new engine. The car has been sitting at the dealer because i cannot afford this, nobody will help me and I don’t know what to do.

Texas Dean

I’m with you. Bought my 2007 GMC Acadia used and after topping 120,000 miles, it quit running entirely. Dealership said GM has been aware of this timing chain defect in design since at least 2012. They quietly issued a “special policy” to pay for repairs under 120,000 miles. But since I had already topped this arbitrary 120,000 mile mark, GM says it won’t pay a dime to fix this problem. They’d rather we all make payments for cars that don’t run. I’ll continue to fight this and keep you posted. GM claims it’s like exceeding a warranty period, but that’s a cop out. How can you exceed a ‘warranty period’ or a ‘special policy’ period they never told you about? If they knew it was poorly designed and would stop running, shouldn’t they fix it?


Do you know what this “special policy” is? My Traverse is honestly just 61 miles away from hitting 120,000 miles!!!

the dog

Same dam thing they did with me on my transmission at 120400 my trans was going out i took it to gm garage and they said Gm wood not fix it because it was 300 over are you f”‘!? Kidding me and i had top of the line extra warenty and they pulled the old oh you didnt change your trany oil enough bite me nest time you want me to buy one of your piles of shit


I just took my 2010 Acadia in for this at 66,000 miles, 5 years 22 days after purchase. Check engine light would come on for a day them go away for several days. Did this for 2 months. I did as the manual suggested, tried new tank of gas, figured it was an emissions problem as the manual suggests; only flashing check engine light are serious. When the light finally stayed on for more than a week I took it in. It never ran rough, not once. I’m a little mad that the warranty was up less than 30 days ago and I’m stuck footing the entire $2600 bill now.


I have a 2011 Traverse, same engine, complained during my warranty period and was told it must be the gas station sold me watered down gas. Now i need a new engine. Apparently my warranty expired 6 days after I went in there the first time and they said nothing was wrong, maybe just watered down gas. Now my car sits for weeks at the dealer as I cannot afford the cost of a new engine. still paying 500/month to the bank for my loan and owe 18,5. any help or advice would be great! Thanks


I too have a 2010 Acadia with 83,000 miles on it. Timing chains are stretched and need repairing, to the tune of $2,000+, and that’s hoping that nothing else is wrong with the vehicle. I’m totally disappointed that GMC knows that this is an issue with the vehicles and they aren’t doing anything to help out the consumers. This vehicle was $48,000 brand new and I’m running into this issue. Wow.


My 2012 has only 60,000 and is in the shop for repair of timing chains, Thry also tried to tell me that it was oil sludge was my problem and GM refused to fix it. My grand father worked for GM for 30 years, would not let me by another brand of car and I’m sure he is rolling over in his grave now to see what they are putting me thru

Chevy guy

I’d possibly try another dealership due to the vehicle having a special coverage policy up to 120,000 on the chains. If you have oil change receipts they help. But it should be totally covered.


I just had mine replaced less than a year ago, now it needs them again but I am not under the certified pre-owned warranty anymore. Do you know if they have a year certified GM repair warranty?

I have a 2009 Traverse w/ 101k miles, and change the oil religiously. Last weekend I had “Oil Pressure Low Stop Engine” appear on my screen while I was out of town. I stopped at a Jiffy Lube and had the oil changed, even though the tech said that the oil was fine, that it was probably an error with the sensor. I brought the car to the dealership yesterday where the service manager told me that he had to pull the engine to replace the timing chain, but he was sure it would be covered under the “Extended Protection” that GM offers on the timing chains (120k). Now, he’s saying that I need a new engine ($10K) because the engine is “all gummed up” due to a lack of changing the oil. I told him that I changed the oil all the time, but he said that the last record he has was Sept 2012, which is the last time I let the dealer service the car. I have it changed at separate oil change facility in town. He won’t do the warranty work now because he says he cannot in good conscience charge GM for something that could have been avoided by changing the oil. He said he’d put it back together (without the new timing chain) and let me drive it home for $900.00, but that’s 100% labor, and he wouldn’t guarantee it’d make it out of the parking lot. I have the place where I get my oil changed pulling my records right now, but does anyone have experience in fighting this? I asked if I got proof I changed the oil, if he’d do the warranty work, but he said that just because the oil change place charged me for the work, doesn’t mean it… Read more »

Contact the attorney Generals office or file a lawsuit.

We have 2010 traverse that did the exact same thing we have just over 100,000 . We also change oil like clock work. Dealership quoted us price 8000.00 to replace engine. I am tearing engine down and doing the work myself. The engine oil is burnt and caked inside heads and timing cover. The timing chain appears to be fine however it is obvious it was not pumping oil. Looks to me GM has some serious issues with this engine, there should be a class action law suit.


Let me knowing it is one I need to file also

Shelley from Michigan
I have a 2008 Acadia. We have changed the oil regiliously. We were out of town last week about 174 mile from home. Our car broke down in Ohio and is still there, it is costing me 35.00 a day for a rental. Luckly we were not on the road when this happened. Right now they have the recall for the timing chains on the 2007/2009 models but not the 2008. We need a new engine and it is going to cost us 6300.00 and we do not have the money. We owe 9000.00 on our vechile and were the first owners. We have been calling GM for the last 3 years about the sludge that has been trapped between the throttle body and the air filter which has caused our car to power down in not the best places. We have been now fighting for the last week for them to replace the engine they are telling my husband and myself that they will give us 1800.00 because we have 118,000 miles on the car. We did not purchase and extended warrenty, but were told that if we did they would cover because there is a TSP. Meaning that under coverage they would change. We spoke to a GM dealer in our town and he told us that the 3.6 L engines were garbage. The dealer that we bought the car from is denying that they new the problem back in november when we took the car in for the recall on the powersteering pump. When then they informed us that they Rack and Pion was also bad and it would cost 900.00 to fix. I called GM again and they were really not willing to help. We also have had problem with our radio and when unhooking the… Read more »

so my bitch, the last 2 years as i’ve surfed the internet searching on ‘engine light / p codes for 2008 acadias’ , finding all kinds of long posts from people with the same issues (like here) , is – WHEN DOES GM FINALLY STEP UP, AND TAKE RESPONSIBILITY ?


Our 2008 enclave timing chain broke at 140 000 km, destroyed engine, GM no help at all, new engine ect. $10 000 repair. Told us our car was not included in any timing chain recall/repair!


I also have a 2008 Acadia. Mine died yesterday while sitting in a drive thru line. It made a weird shuttering noise and that was it. Had is towed to my mechanic who says a need a new engine. Of course, my warranty is expired because it’s a 5 year/100,000 mile and although I only have 82,000 on the car, it is 7 years old.


My 2011 Traverse at 67,000 miles also needs a new engine and I cannot afford it. Were you able to get any help?

Alpine 500

Does anyone have actual info on extension of warranty? Bulletin number etc ??
08 with oil changes per design just let dealer does protest to much!!

I have 2008 GMC Acadia with 89,000 miles. GMC told me that my warranties are all expired but I have a special coverage 13091 which is something to do with the water pump. It looks like I have a crack in my timing change cover. Is it possible that the water pump could of helped with the crack in the water pump?


you do not have to remove the engine to replace the timing chains. have done multiple with engine in car.


Im about to do mine with the engine in the car, wondering if anyone has all the torque info…

2010 Acadia SLT 170000km



freddie ravan

is this a hard job or where do U live and how much to replace timing chaines

April in Alabama

2010 Traverse 97k miles.. engine code p00017 Timing Chain. Dropped it off at dealer, it is covered under the 100k power train warranty. Engine and Transmission had to be dropped to replace it. Mechanic told me the tensioner is what was actually wrong with it. Kept car for nearly 2 weeks. Just got it back and now there are other issues, that I didnt have before. 2 different noises coming from engine. Mechanic said “had to unhook all power steering lines, thats just air in the line, it will clear up. The other noise we dont know, if it dont all clear up in a few days, bring it back”.


I have a 09 acadia that just had the timing chain replaced, now my A/C doesn’t work ( it worked before i brought it in for the timing chain) The dealership is telling me it is the evaporator and is saying that i need to pay for the repair ($2300). I’m of the opinion that they did something to the A/C system when they removed the engine/trans. Any thoughts?


Wow just got my codes read it was talking about two cam sensor being out of time ECM on the first bank and also a transmission code about tranney fluids pressure,sound like what I got going on.


Would you happen to have any faimly photo’s that were taken in Sterling that you would be willing to share? I live in Sterling and am interested in the history. Any photo’s that also include buildings are of interest.I remember your Aunt Francis and Uncle Dugan and Butch, they lived down the road from me when I was growing up.


Just had timing chains replaced on Saturn Outlook at 86K. Just one question. Does the dealership repair what is causing pre-mature wear or will I be footing the bill for next repair at 190k?


I want to know the cost to replace timing chain on 2010 Traverse


The cost to replace timing chains would be about $2,000.

Where is the camshaft position sensor located on the 2009 traverse 3.6l engine. I can not find it anywhere on the web?

Car mechanic

There are several- one for each camshaft. They are located on the front of the engine, they are accessed thought the timing cover.

I have a 2009 Traverse that we bought in June 2013 with 96000 miles on it. Had the timing chain and wave plates repaired at about 97000 miles (so just a month after we bought it). Jan 2014 take it in to local dealership for oil change, three months 3500 miles later took back for another oil change and 3q low. Oil consumption test and now burning close to 3q in 3000 miles. Took it back to dealership and found out that need pistons replaced. Looking at the vehicle repair history found that both the wave plates and the timing chain replaced once before. I am now at 113000 miles and GM is willing to cover half of the $3000 repair. So frustrated with this traverse. Any recommendations.


Anyone have any issues with the 2013 Chevy Traverse? Timing Chain issues?


Just dropped our 2007 Acadia off at the dealership today. They have replaced the timing chain 3 times already with the last time being exactly 3 months ago. Vehicle only has 65,000 miles on it. For the last install the cam sensors had to be replaced also. Dealership charged us $500 and GM picked up the rest. I am waiting to hear what they are going to do this time since it’s only been 3 months.


We dropped off vehicle at a local dealer on 3/28/14 for the issue mentioned in article above for timing change issue. They looked up our vehicle using VIN #. We found out that it was covered under the 100,000 mile warranty along with water pump. We picked up vehicle today 4/1/14


My wife and I purchased a 2009 Chevy Traverse which roughly
had 58,000 miles. We now have 81,000 miles which is giving
codes P0008 and P0017. We are the second owners. Wondering if issue will be covered under 100,000 mile warranty.


I had problems with codes pointing to stretched timing chains. I removed the engine and valve covers. I used a socket to rotate the engine clockwise by hand. One of the intake cam shafts would stop turning for a moment while I was still rotating the engine, then it would speed up again to the place it should be if it didn’t stop turning. I am at this point now and I am going to change out the actuator on the front of the cam shaft as I suspect it is causing the codes and not the chains.

disappointed chevy customer

My 2010 Chevy Traverse with 61k miles on it is throwing the p0008 code. The thing that is confusing is that the light will only be on at certain times. In the morning when I first start up the car there is no check engine light on. After driving it some miles the light comes on again and then if it sits over night the light will be back off in the morning – a friend who is a mechanic is telling me this is unusual.
At any rate I am blown away that a car that has had regular oil changes and been taken care of may need a timing belt at 61k miles. I need to dig out warrantly paperwork but I know I bought the car with about 20k miles on it so I am not sure what the hell my warranty is. I am really scared after reading how big of a job this is and quite disappointed with Chevy that they have not done a recall of cars if this is a persistent problem. This is my first and LAST chevy if I end up paying for this.

Used to my trucks

My wife’s 2010 traverse has 62,000 on it and she just told me check engine light came on yesterday, and oil life at 10%. I change the oil in my vehicles religiously no more than 5k, always using synthetic. She commutes to and from work with it and I rarely ever get in the car. That being said, I looked at the mileage this morning and almost fell out! Just changed the oil in February at 52,000 and the oil indicator let it go 10k to 10% ? I had her take one of my trucks to work, when I drained the oil it appeared to have about 2qrts in it, sickening! Took it up to AutoZone this evening, have the p0008 & p0017 codes. Not surprised timing belt stretch when a car is over half empty in oil and indicator lets it go 10k. Taking to dealer tomorrow, they replaced water pump under warranty 3 months ago ( was overheating on her ) and performed all recalls supposedly. Just got new recall letter for seatbelts anyway, will see how they treat this issue.

2007 Outlook Engine blown

There is a GM recall on the timing chain


I have a 2009 Traverse and this morning is seemed to jump like jumping into gear and made a winding noise then soon after the tracking light came on and stayed on?

Sounds like you may have a wave plate problem in the transmission. Have it checked out right away.

Just got my 2009 out of the repair shop with timing belt failure. Supposedly, some pin from some pump was missing. Can someone share more about their experience with the powertrain warranty? What is the process?

By the way, now the Travey is shaking as if it does not have a suspension. I’ve got to take it back to the shop.

randy singleton

the timing chain can be replaced without removing the engine and trans on outlook. I did


how did u do that,what would u charge me to do mine ?


You replaced the timing chain without removing the motor and transmission? Due tell, how did you manage that?

Just had the check engine light come on for the Camshaft correlation (Thanks OnStar)in my 2009 Traverse. Hoping whatever the problem is, it will be covered under warranty. The dealership just told me Chevy extended the timing chain warranty to 120,000 or June 2019. Obviously they know there is a problem. I just hope it’s my problem so it’s covered!

I just paid over $200 to have 2 cam sensors replaced in my 2009 Saturn, unaware of this timing belt issue. needless to say the problem was not corrected and now have an appointment with a dealer to correct it. Do they replace the cam sensors when doing this repair? I wuold like to get my money back at least for the parts.


No, the sensors are not replaced during the timing chain repairs. The codes in the computer pointed to the cam sensors, but that is never the problem. They mis-diagnosed the problem and it did not fix it, so you should get a full refund.

It was not the dealer but a garage mechanic that initially said it was the sensors (diagnosed by computer) and did the work. I think someone should be sending a letter letting us know that if the engine light comes on we should take it directly to a dealer since this is an issue. I want to be reimbursed for the work by the company. I plan on talking to the dealer directly regarding this…What a waste of time and money!


I had my timing chain replaced yesterday on my 2007 Acadia. It doesn’t seem to be driving as smoothly as before. It almost feels as if it is jumping up and down as I am driving. It feels as if there is a problem now with the shocks, if there are any on this car. What could it be?


To replace the timing chains, the engine and frame were removed. It is possible they left something loose or the front end alignment is off. Take it back ton them right away.


I have an 08 Acadia (not under warranty) whose check engine light came on recently and it had same codes mentioned for timing chain. Before I could get appointment to take it in, it started making horrible sound and died after coming to a stop. It will start up just makes loud clattering noise. Been in garage since waiting on tax return to have fixed. Does it sound like timing chain broke? If so what kind of damage am I looking at? I really love my car and have had no other problems so I hope a new motor isn’t necessary :(


Yes, it does sound like either the timing chain or a chain tensioner broke. If this happened, the engine needs to come out and taken apart. There is a possibility that the valves may have hit the pistons. That would require new cylinder heads. At the least, the chain and tensioners need to be replaced.


I have another question about 2012 Chevy Traverses (not timing chains related, I hope!). We have noticed that when initially driving the car after a night’s rest, about a block from the house there are two noises maybe 3-5 seconds apart coming from under the hood….maybe somewhere in the engine, like something engaging. There is also a definite slight, feel to engaging (similar to shifting but more noticeable). Our son has a 2012 Traverse and experiences the same “happening”. Do you know what this might be? Thank you!


Not a timing chain problem. Could be the A/C clutch engage/disengage. It is still under warranty, so take it in to get looked at.


Thanks so much for posting this info. I’m having this done to our ’07 Outlook under warranty. Our dealer is recommending that they replace the actuators at the same time since they will already have the engine apart. The additional charge to replacing the actuators is $1200. Have you seen issues with the actuators as well or is it just the timing chain? Should I get this done?

Thanks again.


If this repair is under warranty, you should not have to pay for anything ! Nothing !
The actuators always get replaced when doing this job under warranty. The cost is way out of line. Sounds to me like they are trying to get you to pay for the whole job !


Good to know. I’ll just have them do the warranty work. Thanks again.

oh no

We just purchased a 2012 traverse on 12/31/12. It has 500 miles on it. It is at the dealership for the 2 nd time in 8 days. The check engine light is on. 1st time they said they reset something that it should go off after cranking it 7 times- Not. So, now they are saying the acuactor sensesor is bad. Will this require taking the engine out? Do u know if I can get my $ back? We can’t afford these problems on a brand new car.


Well, the repair depends on what part is bad. With such low miles I would not think it serious. We would need the actual code number to be sure.
No i don’t think it would be easy to try to get your money back. That is always a difficult process. A check engine light is not grounds for a buy-back.


I found your web site on Google while searching for a similar issue and your web site came up. I LOVE IT!I’ve also added it to favorites!

I was about to swallow my heart when I got the codes from Auto Zone. – All the same ones mentioned in the article. I have a 2009 Acadia. I baby it with freqent, quality oil changes, but have a 120 mile commute daily to work. It now has 98,500 miles on it and it JUST started running funny yesterday so I went to Auto Zone for codes.

A bit petrified right now….FINGERS CROSSED that I am one of the “most customers” covered in the 100K powertrain warrenty. A little confused because the warrenty states timing belts covered up to the first maintence interval – but I can’t find what that interval is in any of my documentation. Anyone have any ideas?


Don’t worry. If you have all your oil change receipts, this is still under the factory 1100k powertrain warranty.


Hi there, I found your web site on Google while searching for a similar matter and your web site came up, it looks good. I’ve added it to favorites | added to my bookmarks.

My ’09 is in now for this repair. Had a check engine code last summer that was something about a delayed response from some sensor (can’t remember exactly). Took it in for the oil change interval recall, and the code never recurred.

The two codes now are from the crank position sensor and one camshaft position sensor. Had it not been for the check engine light, I would not have known anything was wrong.

The service writer told me that the mechanic who does this work has gotten really proficient at it!

All in all, we’ve been very happy with the vehicle.


I am not sure how long ago you posted to this forum. Today is 10.5.2012 and the dealership has my 09 Traverse and is attempting to fix the camshaft. They called me yesterday asking if I had service records for all my oil changes because of excessive oil build up in the engine caused from lack of oil changes ( so they say). I always change my oil. wondering if you had any issues about oil build up on your 2009 when you had it repaired? I also see that oil build up is a known problem with this make and model. I am afraid of them voiding my warranty because of something that is a known issues. I am also worried about having more probs down the road, since replacing the camshaft effects so much of the car… let me know :) thanks


If you have your receipts, then you are in the clear. Yes, oil buildup is a problem. GM even came up with a reprogramming of the oil life monitor so the light will come on sooner.

do you have to line all the dots up on this engine before you remove chains? If not then why


No, you do not have to line up the marks, since during the repair they will all be out of time anyway. You could do that thou, just to have everything close to the correct position. That may make it a little easier to line everything up.


My 2009 traverse is now in for the timing chains. 86,000, but had this vehical new with all kinds of electrical probelms. Car would look you out, all the guages went nuts, the cruise control would not disingage.


Mine is at the shop now to get this done. <3 yr, <36K mile. Not too impressed. Symptom was the check engine light. Had noticed the oil change interval has shortened quite a bit recently on the monitor. Found out today that last time in <1 yr ago they reprogrammed the ECM. Went from 10K oil change interval to 3K. Hmmm.


Yes. There is a new program for the computer. GM found that the calculations for the oil change monitor system were incorrect causing the interval to be too large. They suspect that may have had something to do with the timing chains wearing out.


i want to watch how to chang timeing balt


I have a junk 2007 Saturn Aura. This is the worst car I have ever owned. Replaced timing chain at 112,000 miles. I changed the oil every 5000 miles. You do not have to pull the motor. I did the job myself. GM is lying to everyone. I am buying a Honda Accord soon. I have owned GM cars all my life. Time for a change.
