Lately, occasionally our Model 3 won't turn off the lights, turn off the stereo or A/C when we park. The car will lock but everything else stays on. Just curious if anyone else has had this happen. I fought with it for for five minutes at a restaurant putting it in drive then park repeatedly until it finally shut down properly.
I wonder if, like any computer or cell phone, completely powering it off - waiting a few minutes - then powering it back on might solve the problem?
1. Open the frunk.
2. Open the rear doors.
3. On the screen tap Controls then Safety then Power Off
4. Remove the upper cowl (between the frunk and the windshield)
5. Disconnect the battery
6. Release the two clips along the bottom of the rear seat (where it meets the carpet)
7. Lift the rear seat bottom
8. On the passenger side, remove the black styrofoam block and disconnect the traction battery
9. Wait a few minutes
10. Repeat steps 9-4 (in reverse order)
11. Wait for the car to reboot.
If there's anything "gunking up" the computer stystem, this will clear it. The entire process will take fewer than 10 minutes and is not difficult to accomplish. Or just do as Bob suggested and take it in for service.
