“I was driving into a parking lot when my back passenger side window imploded like a rock was thrown at it, but no rock and nobody in sight. I looked all around for a cause but believe it somehow spontaneous shattered. Thankfully 3 minutes prior I had dropped my kids at school otherwise there would have been injury I am sure.”Owner report · Unknown Or Other · May 2026

“The vehicle will not shut off when you shift to park. You are forced to sit in the vehicle for extended periods of time attempting to get the vehicle turned off. Apparently Chevy is familiar with eat problem and there are pending class action law suits in Ohio. According to the dealership Chevy has acknowledged there is a defect but no recall has been issued. We have had this issue for about two months and it is getting worse.”Owner report · Engine · Mar 2026
“My vehicle is breaking on its own. There are other vehicles riding behind me and it just stops out of nowhere. I think that's dangerous.

“Shift to Park issue: Known issue where the car fails to recognize it is in Park, preventing it from shutting off. Electronics: Potential blanked-out display screens, USB port issues, and malfunctioning cameras. Steering Assist: Restricted, temperature gauge goes to cold and radiator fan blows hard. I have to unplug negative cable to battery and reconnect and everything goes back to normal.”Owner report · Power Train · Feb 2026
“I believe my thermostat is a problem. I keep getting "P012B" "coolant under operating temperature" codes on my obd2 meter. This seems to coincide with "driver assist reduced" on my instrument cluster on my dash board. I researched it and on a forum it sounds to be a very common problem. Someone said to report it on here. I can clear the "p012b" error code with my obd2 and my thermostat instantly becomes responsive however it comes back within 2 days or so.”Owner report · Unknown Or Other · Jan 2026

“We are noticing the coolant meter seems to be stuck on C, the AC is not blowing cold and we are getting a message that ACTION REQUIRED steering assist is reduced, drive with CAUTION. Today the brakes slammed on by themselves and almost sent my wife thru the windshield. Luckily she was in a clear area with no other cars around.”Owner report · Steering · Nov 2025
