2006 Chevrolet Trailblazer Engine Light And Misfire Codes

2006 Chevy Trailblazer with 4200 engine and 50,00 miles. why a cylinder #4 and #6 leak?

ProTech:
What kind of leak?

Sorry 50,000 miles. the dealer said they did a leak down test.and the head has to come off for repair. $3,ooo job they say and told my wife vehicle is not worth fixing . Give me a break!!

The 2005-2007 models had cylinder head problems. If you call and complain to GM about it, and have records of proper maintenance, they will probably end up fixing it for you for free.

I work as a heavy duty truck mechanic. I do all the general maintenance on my 06 trailblazer. I hope Chevy will stand by their product and do the needed repairs. I change the fluids and maintain the vehicle regularly but do not have receipts. Is this a big problem?

It probably will be. In fact, I just wrote an article about how keeping your receipts for the do-it-yourself person is very important when you need a major repair at the dealer. They will want to know that it’s been properly maintained, if you can’t provide receipts, they won’t take just your word for it. Also, they can site abuse very easily as the cause and will tell you that you’re on your own. It’s worth a shot to give GM a call, the worst they can do is tell you no. Plus if you’re a mechanic, you may try and save some money and do the job yourself. Also if you haven’t given the dealership that the vehicle is at a lot of business over the years, they are very less likely to help you out.

Great, thanks for the information !

Your welcome.
