Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The instrument panel cluster gauges don't always work. We were on freeway when we noticed speedometer had failed as well as fuel gauge , temp gauge all gauges inoperative. This is third time cluster panel is being replaced; first two under warranty third time we had to pay $204.”
NHTSA complaint #11025209, filed 2017-09, 111,000 miles“My ignition also switches off due to the key chain being to heavy, I would like my vehicle fixed as well. I think GM is not telling the whole story on how many vehicle are affected by the ignition switches. I can prove my claim by attaching my two key chains together again and the problem will occur again.”
NHTSA complaint #10577755, filed 2014-04, 80,128 miles“Parked my truck in the driveway tonight and shut it off. The mirrors went crazy, and the radio would not shut off. After a few minutes I started the truck and shut it back off. The radio went off. Since owning the truck, which is not very long, I have had the power seats readjust themselves, by them selves, and it felt like it was crushing me. I am a big man and I prefer that no one adjust my seats, as I have them just right for me. This truck and its wiring/electrical system are problematic. So sorry I bought it now.”
NHTSA complaint #10605775, filed 2014-06, 124,000 miles“Failure of speedometer and oil gauge. Was contacted by GM to replace the instrument panel. Because I had more than 70k miles they said it will not be replaced. Even though they admit to a failure of the system, since I cannot prove it happened within the 70k mileage they are refusing to replace it. This is a tremendous hazard and is very costly to replace. A dealer quoted me $850. Thanks for your help.”
NHTSA complaint #10209575, filed 2007-11, 48,000 miles“Driving on the interstate, my speedometer started indicating I was doing 20 MPH while I was actually going at least 60 MPH. It proceeded to only indicate speeds from approx -10 MPH to 10 MPH. Then the oil pressure gauge went 180 degrees beyond it's max, then the battery gauge did the same.”
