I have a 2021 Sierra 1500 AT4. I've been having rear park assist off issues since day 1. Initially it was almost every time I trapped the gas the rear park assist would shut off. Just the rear not front. Took it in and was told they did an update. On the way home it happens 5 times. Went back in and they ordered a module. Had that replaced and since then it's happened maybe 3 times a week. Much better than every time I hit the gas but still happening. Anybody hear anything new on this?
