I was driving and came to a stop at a light and all the sudden in my car just shut off. It took me a minute to try to turn it back on while cars behind me honking their horn. I’m assuming it has something to do with the electric due to the start stop button. I don’t have official incident report because I was able to get my car turned back on. I looked it up on the Internet and several people are having this issue.

We have two problems what we would call safety issues. First, all the sound in the vehicle was lost which included safety belt warning alarm, turn signal bells, door open alarms, etc. We were told by the dealership that it was a faulty amplifier. Secondly, the sunroof opened by itself, and is locked in the open position which makes the vehicle undrivable due to weather conditions and makes it an easy target for theft. The vehicle was locked and parked in our driveway when we noticed the sunroof was open. We know this occurred on it's own as we had just washed the vehicle and locked the doors. The next day we found the sunroof open and the doors still locked. This is a computer software issue within the vehicle as these issues occurred within a matter of days of each other. The sunroof opening on its own is a safety issue as a unsecure car is a problem, opening during traveling in a storm is a real threat to driving conditions. During our investigations we have found other cases the same as ours.We have reached out to GMC and we were told no recalls have been issued and to file a complaint with the federal safety agency and our state Attorney General. Our vehicle has been sitting at the dealership since August 5th, waiting on back ordered parts with no anticipated delivery date for those parts. This is not a dealership issue but rather a manufacturer design defect. Buick has not taken any interest or responsibility for this issue as the vehicle was out of warranty recently. This 2020 vehicle only has 55,000 miles. I have a 60-mile roundtrip commute to my job at a local hospital and have been without a vehicle since July 28th. This issue is not due to any neglect on our part and the cost so far is over $3,000. Buick should be responsible for their design and poor engineering as this has the potential to cause an issue if this happens while the vehicle is moving. The safety bells are an added reminder to buckle up and if they are not working it is a safety issue for those in the vehicle.

Got in the vehicle to start the engine and the instrument cluster stop showing all readings of the gauges would not display the screen blacked out and none of the gauges were working. There were no warnings lamps or nothing out the ordinary the instrument cluster just went out. This is the first time it has ever done this.

The Air Bag, Parking Brake, Traction Control/StabiliTrak/Electonic Stability Control lights all came on while operating my vehicle. The lights did not go off, so I reported to the dealership. They determined it was an internal defect in the Inflatable Restraint Sensing and Diagnostic Module. This was not covered under warranty and appears to be a defect in the module. I believe this to be a serious safety concern and recommend a recall of this issue.

I put the car into park and I exited the vehicle because I forgot to push the stop button. So I reached accross the driver's seat and push the stop button. When I did this the car began to roll back as if it was in neutral. I did not touch the shift knob. It shifted into neutral on its on. The front down was open at the time. The car should not have moved if the front door was open. The car ended up rolling down a small hill and ran over me.
