Hi. I just got a 2016 GMC Terrain a few days ago and I get a humming noise like an electrical motor or pump running, coming from under the hood. The noise only lasts for about 5 seconds and then stops with a click. Sometimes it starts with a clicking sound. This happens with the engine and ignition off and even if the engine is cold. It will stop for 1 or more minutes and then repeats again. It is not the electric fan and seems to come from the battery area. It might be happening also when the car is running but I just can’t hear it then. Any thoughts or is this normal?
