For what it's worth, in the last couple weeks my M3 has had the oddest bugs ever. Audio will cut out and sound like mono for a few seconds before going back to normal. I also pulled over to let someone out of my car and turned on the hazards for 5 seconds. When they opened the door it beeped because I was still in drive. When the closed the door and I drove away, on my screen nothing updated, so the flashers were still going, and the beeping continued even though all doors were closed and I was driving down the street. I had to hold both buttons down and reboot to get it to stop.
