Tesla 3 Unresponsive

Hi! new over here.
I have a model 3 and for some reason the vehicle is stuck displaying the Park icon, and it won't go into any gear, doors open and close but car doesn't seen to power off or lock. also unable to put on transport mode.
the car charges , just completed the latest software update and have tried rebooting it, unplugging the 12v battery and the disconnecting the battery pack under the rear seats.
any help will be appreciated

Might need a new 12V battery. How old is the car?

Might need a new 12V battery. How old is the car?

it's a 2021 but already has 51k miles.
from the app I can send a command like start or lock but it won't do neither.
windows roll down and the doors open, the frunk does not.
I will try the 12v battery

A 2021 shouldn’t need a new 12V battery regardless of mileage, but the service center can check it for you. Covered under warranty.

Since the OP states they have 51k miles on the car, the only thing that would still be covered under warranty is the actual HV battery. Luckily, the 12v on a tesla model 3 is cheap, so hopefully its the 12v battery.

I stand corrected, but it’s unusual for a 2021 car to need a new 12V battery regardless if mileage. If it is the battery, maybe Tesla will replace it for free as a goodwill gesture.

just replaced the 12v battery and still dame thing. it just displays the parking brake sign and you can't drive. can't put it in transport mode, everything else works other than the steering being hard also.
