In October 2021, while driving, the car lost power. Several indicators displayed at the time, including: • Service Engine • Service Stabilitrak • Service Antilock Brakes • Service Transmission I managed to pull the car to the side of the road and restart it, but it was stuck in first gear. After several restarts it performed normally. I took the car to Miller & Sons, they told me they could not find a code and the car was performing normally at that point so there was nothing they could do. They told me if the car did it again, to bring it in immediately so they could get a code for the malfunction. Two weeks later, the same malfunction occurred, I took the car directly to Miller & Sons. Once again I was told they could not find a code or problem and I was sent away again. The third time this malfunction occurred, I was driving at 40 miles an hour and the car began to accelerate on its own. I could not brake, shift to park, shift to neutral, steer or apply the emergency brake. After about 15 seconds, the car shut down in the middle of the road. It could have caused death or seriously bodily injuries to me or others. At this point I had the car towed to Miller & Sons. I am told that while test driving the vehicle, it also accelerated on the mechanic [XXX], almost causing an accident again. At this point the told me they found 60 codes dating all the way back to the first incident, but they still did not know the problem, they replaced the Transmission Control Module in hopes that would solve the problem. It did not. In August, the same thing happened. They replaced the transmission control module again. About a month ago (September 13) it happened two more times. It is still sitting at Miller & Sons. This time I contacted GM for some assistance. I was using the messaging system (case number [XXX]) I was told a senior advisor was assigned to my case and that a TAC team would consult with the dealership to diagnose and correct the problem....
