Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The second row seats get stuck from time to time when attempting to fold them down. We have also been having issues with the shift gear when trying to place it in park. When the car is placed in park and we try to turn it off, the car will refuse to shut off and will ding until finally the car registers that the shift gear is in park. I have to turn on and off the car multiple times, and even wiggle the gear multiple times before the system finally recognizes that the car is in park.”

“The service stabiltrak notifcation keeps coming on and shutting off on its own while in motion on a street and it has also happened while on the highway. It has occurred at different speeds and several times with different people driving.the dealership can't figure out why and it doesn't show it even came on at all. When in motion on a strret going 46mph the car tried to auto correct pulling me out of my lane by itslef. It was a straight street with no curves where this occurred. Thank god there wasnt a car in the lane next to me. The side mirrors reset themselves all the time. …”

“Front seats feel loose and like they shift. When they shift and move a popping noise is heard. The shifting and popping noise happens in and out of corners, going over driveway/parking lot aprons. The sensation is unpleasant and irritating. Have spoken to dealer and auto body shop. Associates claim similar problem existing with yukon's. Does Gmc have a seating problem or recurring defect?”
