Hey folks, I have a new (~2k miles, but older firmware) Model S 75D loaner right now that seems to be stuck in an MCU reboot loop - the screen comes on for about long enough to load the maps (maybe 4-5 seconds), then goes black, kills audio/climate/etc, I see Tesla logo, then the screen loads and the process repeats. I've read through forums and googled, and tried all manner of reboot short of a reset in the settings menu (I don't have the car's account info) to no avail. Any suggestions for how to fix this? Supposed to be leaving for a road trip in about 3 hours, and have meetings until then so can't spend time on hold with service. Thanks so much!
