I have has my M# 2 weeks. Today I had my second black screen when I get in the car. Both times the car was left fo 20 ish hours without driving. the first time the screen would come on after reboot but failed again after shifting into reverse. 2 hours later it worked after a 3rd reboot. Today the car was derivable reboot never showed the TESla logo . tries entering and exiting the vehicle. Could not wait more than a 5 minutes. 1 hour later when I got back it was working. No way top schedule a mobile appointment but after the appointment 1 week out I called and they are going to look at the footage. needed exact times and see if they can fix it remotely. Not happy with the salespeople saying95% of service is done at your house but it is a real hassle to schedule it.
