The truck randomly gets stuck in park. cannot put it into drive, neutral or reverse. the car has been at the dealership since january 27, 2020. gmc wont send them the part, the dealship believes it must be a problem with the part and they are trying to fix or redesign the part before its sent out. also i was told by my dealership another 2020 at4 came in with the same problem. it was towed to them.
