A bunch of problems appeared the other day on my 2019 M3P:
I rebooted the car via 2-button press probably 10x to no avail. Found a Reddit thread with an owner experiencing similar symptoms - another poster pointed to a corrupt USB, advised to remove it, and do another reboot. Seemed to work for the OP. Not for me.
In the end, I basically "completely" turned the car off & on again. Stupid simple procedure - sounds scary, but isn't. Just be careful not to lock yourself out of the car, otherwise you'll have to open the frunk via the emergency leads behind the tow hitch as described in the manual.
1. Pop the frunk open
2. Open all windows to avoid any damage (since auto-up/down will be disabled)
3. Ensure the HVAC has been off for 30+ seconds
4. Power down the car thru the screen Controls > Safety & Security > Vehicle Power > Power Off
Then
I left the rear right door cracked so I wouldn't have to worry about a lockout condition.
- GPS was stuck in one location
- No cameras worked
- Autopilot/cruise control stopped working
- The screen's day/night setting inexplicably wouldn't change over...

Then
- Open the frunk, remove the under-hood apron
- Disconnect the 12V battery negative terminal
- Lift up the rear seat - there are two "sliding" latches on the leading edges under the cushion
- On the right hand side, you'll notice a high-density foam block that covers the connector to the high-voltage battery (HVB)... lift it out of place to reveal the connector
- Unlock the HVB connector by pivoting the little gray latch outwards - this will start pulling it out. At this point, the HVB connectors will immediately open and you'll hear a clunk - don't be alarmed.
- Cover the connector port on the battery with a rag or something just to be safe (for the battery's sake)
