Example complaints

“Shift to park message started coming on the display even though the vehicle is in park. Once this message comes on, I am unable to turn the vehicle off. I have to keep putting the vehicle in gear and park again several times until the message goes away. I have video of the issue but dont see where it can be uploaded. There is also a class action lawsuit in conn about this issue.”
NHTSA complaint #11406856, filed 2021-04, 40,760 miles“After placing my car in park, and trying to cut off the engine, it alerts me to shift to park ... I will have to restart my engine, put it in neutral and then back to park, and try again to shut off the car. Sometimes it works on the second attempt, but usually takes 3-4 times of cutting engine off and on, shifting from park to drive to park again. If you attempt to exit the vehicle, the horn will start to honk, and alarm goes off. …”
NHTSA complaint #11405837, filed 2021-03, 32,500 miles“I have experienced issues with the shifter of the vehicle twice now and it has resulted in replacing the shifter at least once. 6 months later and after an initial replacement the shifter has gone out again. The shifter refuses to move out of the park function. Prior to the shifter going out the car would say shift to park even though the car was already placed in park. I believe the issue to be an electrical problem. The middle seat belt in the second row of the vehicle has also stopped working.”
NHTSA complaint #11326167, filed 2020-05, 26,000 miles“First time back in june 10th, 2020, I took it in because of remote not detected they could not duplicate the problem, few hours later, same day after I picked the car up it went haywire while parked. It threw itself into theft mode, would not let us manually lock the car, electrical was still on but engine was shut off, alarm, windshield wipers, and lights was going off while I had it towed to the dealership. This time they've told me, the A/C condensation fried the cpu module because the only thing keeping water out of the cpu was a tray. …”
NHTSA complaint #11374063, filed 2020-11, 10,767 miles“My mother has become trapped two times due to the locks on the vehicle not working. The issue only happens when it rains. I took the vehicle to the dealership and they said they replaced some kind mechanism and that everything was good to go. It rained again yesterday and my mother was trapped in the vehicle again. This happens anytime you try to engage the locks, I.e. In park, putting it in park, putting it in drive, using onstar to lock or unlock, using the Gmc app to lock or unlock, using either key fob to lock or unlock, trying to lock or unlock it manually.”
