Hi all!
I’ve been having some intermittent 12V issues on my Tesla as I was getting messages on a couple of drives that my 12V was disconnected and cabin camera was disconnected over the last week or so. I had planned to schedule a service appt if they continued, but it seemed to be a few days since the problem occurred. I had a low 12V issue less than six months ago and had a new battery installed. These weren’t the same messages, so didn’t think I needed a new battery.
So yesterday, I get the latest FSD beta notification and started the update. When I checked on the car about 30 mins later, my app said that it had connected to the car 7 mins earlier. When I went out to the car, the doors, lights, etc were all working fine, but I wasn’t getting anything on the screen and the car was otherwise dead. I tried a scroll wheel reset/reboot, but nothing worked. I plugged the car in and hoped that it would be alive by morning. I did leave the driver’s side window down though just in case.
This morning however, nothing worked. I couldn’t disconnect the power and the doors would not open. I used a 12V battery to pop my frunk and when I looked at the battery, the negative terminal was completely loose. That had to have been the case since I had the battery changed, or the nut had worked itself completely loose.
I put a charger on the battery and let it charge up. The doors, lights, etc all began working again but still nothing on the screen or any life from the car.
I am concerned that the 12V power was cut while it was doing the update and now the car is bricked. I set up a service appt at the closest Tesla center for next Tuesday, but I will have to have it towed there.
Are there any other ideas of how I can try to revive the car?
Thanks for any help!!
