Car needs/requires service and 12V power reduced - Won't drive...

[Tessy]

The following warning notifications came up on my 2018 Model 3 with less than 8k miles;

• Care needs service (Car may not restart)
• 12V power reduced (Vehicle may shut down unexpectedly)
• Vehicle required service (Schedule now)

The issue is the car will not shift into drive or reverse. I tried rebooting and I fully recharged the 12V battery with no help.
Any input or suggestions would be greatly appreciated.

Where? Weather? Last used? Voltage after charging 12 V battery?

There is a 12 V reset that is more complex in the Model 3:

• Lift rear seat to disconnect the traction battery systems.
• Disconnect the 12 V ground for about a minute. NOTE: the voltage should be between ~11.9-12.85 V. If too low, good time to replace (see YouTube.)
• Reconnect the 12 V ground
• Reconnect the traction battery systems.

If this does not work, it sounds like a service truck or tow.

It's looking like the Pyro Fuse is the culprit. Any chance anyone in Southern LA has a 5 Point Socket I could rent for removing the penthouse lid?
