I am pretty confident that your 12v battery is done. Car is not covered under warranty any more or maybe I should say the 12v battery is not covered. You can easily get into the car by following the procedure to jump it by connecting 12v to the terminals behind the tow plug on the front bumper.
The battery gets its charge from the main battery via a DC to DC charger and is not working so the 12v is most likely toast. You have 2 options, replace on your own with a group 51R from where ever, heck, even Walmart has them. If you have a service centre close by, pick up a Tesla one. Or, wait for Tesla to come out and swap it for you but that will be several days at best.
Good luck with whatever route you choose.
If you cannot open the frunk using a samll 9V battery, to disconnect and reconnect the negative of the 12V battery to reset the car,
please review the following steps:
PART 1:
Does you App still work? Like can you activate the horn?
If so, go to the
Climate control on your App, and try to
lower the windows a little bit.
All the windows should have then a one inch crack.
If so, try finding a little piece of wood or a plastic tube, and bent it a little bit at one end.
Try then to reach inside the car, the open button of any door.
This should allow you to open any door.
If you are able to open a door, go to your screen and try using the
soft reboot using the Service menu and Close button.
If the screen is not responding, try pressing the brake pedal and the two scroll buttons on the steering wheel.
If your screen is running, try then to activate the Service Mode
- by going to Software and then
- pressing the Software word in the middle of the screen for five seconds,
- and enter the password 'service'
If the Service Mode can start, look for any messages using the sub-menu on the left.
Part 2:
Try to open the frunk using the screen. If not working, try using a small 9V battery
using the wires located inside the front tow hook.
If you cannot open the frunk or the trunk using the screen, or using a small battery, you need to perform a
hard reboot.
Do do so, you need:
- to raise the bottom booster of the
rear seat (there is a little plastic knob near the right and the left)
- on the
RIGHT side, there is a plug with small wires.
- Try to
pull down the handle on to of the plug to disconnect the connector
Note: Do not touch the LEFT plug with the big orange wires.
After waiting a little bit, like 10 to 20 seconds, then
plug back again the plug located under the rear left seat.
After disconnecting and reconnecting the small plug, the screen should starts again to run.
Check then for any messages using the Service Mode.
Do not close any doors.
Part 3:
Try to check if you can
open the Frunk using the screen, if not try using a small 9V battery.
When the frunk is open, check for the 12V battery voltage if you have a voltmeter.
Put a piece of cardboard on top of the lock mechanism of the frunt, so you don't close it accidently.
It is possible that the internal DC/DC converter ill be able to recharge the battery,
however you might not be able to drive the car.
The next step will be to replace the battery. You can get one at the Service Center for about $70.
Part 4:
If you need to have your car to be tow to a garage, do the following:
- Try to see if you can go to the TOWING MODE under the Service menu.
- This will allow to unlock the parking brake, in case you need to move the car.
- Otherwise, the towing company will try to drag your car with the rear wheels locked.
- If the towing company don't use a dolly under the rear wheels, this can damage your suspension.
I hope you will be able to perform the PART 1 and then the Part 2 and Part 3.
I imagine anyway that this are what a mechanic will do.
I hope you will not have to do the PART 4.
