UNKNOWN: Approximately once a week, all of the sound stops in the vehicle including the blinker sound, radio & connected phones. I'm unsure if affects anything else. I have googled this issue and it seems as if other GM vehicle owners have the same issue. There were no warnings or warning lights.

The car turned itself off while driving 55 to 60 mph on a highway. Would not turn back on after getting to the side of the road. Very dangerous.

Had an issue where the left/right turn signals stopped functioning. This occurred while in-use while waiting to make a turn. Shutting the car on and off did not correct the problem. Contacted dealer and advised to bring in. I chose to disconnect the battery rebooting the vehicles BOM. Issue resolved after a vehicle reboot. This is a serious software issue.

I was driving on the interstate and my sunroof exploded. There were few cars around me and I was not under a bridge. I did not see anything coming at the car or see anything drop or fall behind us. Just heard a lot exploding noise.
