Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“In 2 days, the vehicle has stalled on me. I was in the parking lot and another car almost hit me since the car slowed down and the steering wheel got hard then shut off. Today, I almost got hit again after stopping at a stop sign going into a turn I almost hit someone and a car almost hit me.”
NHTSA complaint #11120797, filed 2018-08, 41,971 miles“I own a 2015 Gmc Terrain. The radio and all other functions related to the touch screen have failed resulting in a black screen. This includes the back up camera. This has also contributed to a minor accident where I back into a utility pole. Gm states a new radio is necessary at a cost of $1287. This is unacceptable for a vital part of the vehicles operation. What will it take for GM to address this issue? Someone backing over a child in a driveway?”
NHTSA complaint #11327916, filed 2020-06, 65,000 miles“Third time while driving on city streets the car begins to shake and stall. I pull over or stay in place as the car proceeds to turn off. The service stability traction and engine lights light up and the car dies. Each time I am able to turn the car back on within a few minutes.”
NHTSA complaint #10980153, filed 2017-04, 44,000 miles“Three times when I want to start the car it starts and turn of at the time driving backward to get out of parking space. One of the cases was at the time I wanted to go forward”
NHTSA complaint #11089290, filed 2018-04, 45,000 miles“Started march of 2017 progressively getting worse. Suv jerks, gauges go crazy, check engine light comes on, if slow to below 20 MPH it sputters and won't accelerate, if I stop completely it won't accelerate. Multiple times this has happened on the interstate during rush hour traffic & at busy intersections. If I turn car off and back on the system resets. Then it starts all over again. It has been in and out of the shop. Probably 10-15 times in 2years. They get codes, but then these go away before they can be 'run'. I broke down 1-1/2 weeks ago in bay minette & the car wouldnt start back up. …”
