Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Front passenger seat caught on fire from the seat heater. The vehicle parked and turned off. It was parked in a high school parking lot while my daughter was in school. We contacted Gmc, but they said it there was nothing they could do. There was something that went wrong for it to just catch fire. Can you help us in anyway at all.”
NHTSA complaint #11288638, filed 2019-12, 150,000 miles“My dash panel gauges began failing one by one. My headlights will sometimes not come on after starting the car with the headlight switch on auto. A flick of the headlight switch in and off, does not make the headlights come on. Sometimes they come on after driving around, and then will go off without touching the switch. Now, my side brakelights will not operate correctly when the brake pedal is pressed. Only the third brake light illuminates.”
NHTSA complaint #11258245, filed 2019-09, 67,000 miles“Stopped at street like, light went green started to move forward and car goes dead. No lights on dash, nothing showing, just stops abruptly. After a few moments tried restarting car and it came back on with check engine light. P0606 PCM failure code displayed. Could have been rear ended by semi truck behind me or killed if I was trying to turn left at intersection.”
NHTSA complaint #10606588, filed 2014-06, 78,000 miles“Parked the vehicle in a parking garage so I know the lights were working when we went in. As we were leaving approximately 3 hours later, the low beams would not come on at all. Had to run high beams; had several people look at the fuses, replaced bulbs, etc. But they could not find the problem. A couple of weeks later just before I was taking it to a dealer to look at the problem the low beams began working again. …”
NHTSA complaint #10676142, filed 2015-01, 127,000 miles“Engine stalls when you slow down and the air conditioner or widow defogger is on . I have also had power surging. I had to replace the map sensor twice and the bracket and it is still showing bad. I also replace the cam shaft position sensor and the thermostat. Also the wiper on the rear will not spray any water or washer.”
