Super scary! I was driving back home on Thursday 10/15 late evening ( 8 pm) when I put my MX in autodrive mode. Suddenly the screen and the speedometer turned black, as if the car has stopped working. This was the very first time for me...super scary. I was at 70s speed, turning the indicator to exit ( not knowing if it was even working). The A/C was automatically turned to cool which added to the panic situation. I got lucky in taking the nearest exit to catch a breath...by which time the system was back up. So this was a case of reboot with no indication.
