At 550 miles had to tow to dealer. They said needed to reprogram transmission. Now at 4000 miles, went to start and vehicle will not do anything. No power. It is being towed to dealer again. Pretty much bought a lemon as it looks now.

Sierra 1500

  • 250 miles
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.
