Engine overheating by model year
What owners say
The daytime running lights have failed due to what appears to be the overheating of the lamp sockets. When you go to replace the lamp' the sockets appears to be burnt and brittle and are missing the little metal tabs used to make contact with the lamp base. You cant replace the lamp. Therefore I only have 1 daytime running light and am worried about a possible fire hazard with the other one. The one that works looks like it's not far from failing and very soon wont be working either. The more I see the amount of gm vehicles (trucks, silverado, tahoe, trailblazer, sierra, yukon & envoy's) without two daytime running lights, I really do wonder if gm has a real problem. I see several each and every day without one or both. I have spoke to other owners and they have the same problem with one or both of them. Thank you for your time.
Reduced engine power message and drops into "limp mode", there is no problem with engine overheating. The computer give a code 1516 "drive by wire" sensor calibration problem. Dealer indicated "yellow" wire broken on some vehicles others have to replace the throttle sensor. Danger is on loose of power in traffic, instead of a message to check the engine.
Failure of the left front wheel hub bearings. Resulted in severe wobble while driving, especially noted in turning to the left. Dealer advised this was a serious problem and could have resulted in wheel failure or fire due to overheating. Vehicle has under 42,000 miles.
Vehicle brake control electrical wiring, that controls the trailer failed. It engaged by itself and overheated. The dealership replaced the part. Cause unknown.
