Example complaints

“There dashboard cracks really bad and apparently this has been an ongoing situation with chevy and GM vehicles. There's lots of static and I get shocked all the time which shutting my vehicle off or starting. I have had no off market work done to my vehile so its all as it was when original purchased.”
NHTSA complaint #11338105, filed 2020-07, 113,000 miles“Service traction control and check engine lights came on this morning. Then a message saying my engine power is reducing. I just bought this car 3 weeks ago. I called GM customer service and they told me there was nothing they could do, even though there was a recall regarding this because it was over the 120000 mile warranty (but I just bought this car 3 weeks ago!!!)”
NHTSA complaint #10839873, filed 2016-03, 120,473 miles“Started car had car for 2yrs now no problem what so ever and the service traction and stability control and also reduced engine power came on as well as engine light it jerked went it shifted and didn't act like it had it power as always but I just drove it 35 MPH to get it home this I would think is a great big safety issue shouldn't GM have a recall on this?”
NHTSA complaint #10583616, filed 2014-04, 47,000 miles“Door system on the car has failed multiple times where I have to take the door apart and fix it. It's not all 3 doors it's just one door. I understand you may not think this is a safety thing. But I'm a firefighter and let me tell you that if I had someone in the back seat and I get in a crash. How are they suppose to get out? Since I have a car seat on the other side. Especially if the car catches fire. I guess someone dying will have to changed that.”
NHTSA complaint #11142297, filed 2018-10, 130,000 miles“I was stopped at a light and the front end hesitated then took off normally. I got on a highway, drove 30 miles and as I was decelerating my check engine light came on and a message to service my traction control light appeared. I looked up this problem on the internet and see that it is a common problem across many models and numerous model years. It was suggested to log the complaint .”
