Just happened to me today. First time I've had it happen. Stopped at store open/closed door and radio kept playing. I opened door again and powered the radio off. Coincidently when I got in car today radio chimed and indicated there was an update that needed install. I dont know if its related. I did the update when I got home but have not used the car since.
Talked to my wife earlier today. She said it did an update and now the radio shuts off. She didn't have to take it to a dealer. It did it on it's own. Took 12 minutes.Just happened to me today.
