2021 Sierra 1500 AT4 Standard box 6k miles My park assist turned off about 20 miles from my house. The light on the park assist button on the center console was off. Arrived home and started to play with the vehicle settings in the center console and selected the collision settings. Park assist was on the settings and turned it off and back on and then assist turned on with the center console turned back on. So that seems to be a short term fix. I’m going to continue to monitor it. But small stuff like the truck telling me I’m on the wrong road even though I don’t have navigation on, is beginning to worry me.
