2022 Buick Envision

Car applied emergency braking when it should not have (and could have caused an accident)! Details: Driving approx 20 mph in traffic on highway in Houston. Approx 3-4 car lengths behind vehicle in front of me. There were cars to the left and right of us, .. they were staying within their lanes. For no apparent reason, the automatic braking system applied the brakes. The four of us in the car were jerked forward. Luckily the driver behind us was not tail-gating, or we would have been rear-ended. Note: This was a National rental car I had in Houston this past weekend. Nonetheless, I want to report this as this apparent software and/or sensor bug seems like a major safety risk to me. I tried to find a way to report this to Buick too, but they don't make it easy to find a way to report a safety complaint : (

Service Safety Restraint System warning and Airbag light comes on and off multiple times a day. Onstar and Dealer state they cannot recreate issue or find a code. I have pictures of the warning. It is very distracting when driving and warning bells are sounding and messages are popping up that take my eyes off the road. This vehicle has ~2500 miles and began at ~2400 miles.

My vehicle still has a delay or hesitation with the shifting of gears while driving, causing a loss of power. At random times the vehicle has lost power while driving. Additionally, when the vehicle is turned off, there is a loud noise (knocking) coming from the front of the vehicle. Also, while driving there has been a burning smell. The vehicle is again scheduled for repair of the persistent issues that GM-certified specialists say the issues could not be duplicated. Recently the infotainment center blacked out after being the software updated. The screen produced issues with a variation of colors which disabled the use of the infotainment for several hours with the screen frozen. This is my second report of the same concerns with the same vehicle reported on 2/22/2022 as this vehicle is only six months young. The vehicle was inspected by GM's branding inspector in April of 2022. GM informed me that they did not find any issues at that time, but offered a settlement of repairs of 50,000 rewards points unbeknownst to me. As of June, GM offered another settlement offer of repairs only. However, GM has stated there are no issues. A lemon law warranty claim will be submitted.

What component or system failure or malfunction, and is it available for inspection upon request? AUTO STOP/START-POSSIBLE TRANSMISSION How was your safety or the safety of others put at risk?- The issue is the AutoStop feature and the transmission. When driving, it appears that the gears are not shifting correctly; also, while driving, the RPM has reached a high level of 5 multiple times, which is now a cause for concern. My minor son and I were driving today, and an 18 wheeler started veering into our lane. When I sped up to move over to the next lane, the vehicle hesitated, the engine revved up, and the vehicle started moving slowly. Has the problem been reproduced or confirmed by a dealer or independent service center? The vehicle is en route to the dealership. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not yet Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NO  The issue is the AutoStop feature and the transmission.

The contact owns a 2022 Buick Envision. The contact stated that the vehicle was parked in the garage while he was working in the yard with the vehicle fob in his pocket. The contact stated as he walked into the garage, he noticed that the vehicle was running on its own. There was no warning light illuminated. The contact sat in the driver's seat, put his seatbelt on, depressed the brake pedal, pushed the turn off button and the vehicle turned off. The contact stated that the fob alone could not start the vehicle as the vehicle was designed to only start when he got in the driver seat, locked the driver's door, put his seatbelt on, and pushed the start button while in possession of the fob. The contact also attempted to start the vehicle with the fob alone several times to determine whether the fob alone could start the vehicle, but he was not successful. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The approximate failure mileage was 1,415.
