I have a 2019 Chevy Colorado, my radio also turns itself off and back on while driving. It has since 36000 miles was hit. And just yesterday I was on the phone and the screen showed it was still connected but I had to turn on phone speaker just to end the conversation. It reconnected when they called back. I work from home so I don't drive often, mileage is 36645 currently. And all diagnostics show everything is as it should be. UGH! This is very frustrating and potentially dangerous in my opinion.
