2022 Chevy Tah with 32,292 miles of in-town and highway driving, never any towing. Perfectly maintained on time. Suddenly started to not respond to acceleration, and jolting, then would not reverse. Transmission valve body has already gone out. GM acknowledged the problem. States there is a national shortage of this part. There is nothing they know of being done about. Park the vehicle and wait for a part to become available. No ETA, but 2,200 of this part have already been requested recently.
