Dead model S

[Paul S]

my wife’s 2014 model S died yesterday. She parked it in the garage and plugged in - next morning the car got stuck on “powering up” . Numerous reboots to no avail. 24 hours later still “powering up.” Tesla mobile service tried everything - still unable to move the car. Looks like the cars computer may need to be replaced. Naturally after the four year warranty has expired.

Oh man, I have no clue what this could be but obviously very interested. I hope this isn’t a costly repair for you.

Could it be a dead 12v?
Tried jumping it?
Why didn't you renew the warranty?

...Why didn't you renew the warranty?

Because it is cheaper to pay this single repair rather than to pay in advance for $4,750 ESA.

However, if there's another repair such as heater, both methods would break even as long as there will not be a third repair.

Not sure how DIY you are, but you could try unplugging the service/ emergency responder loop in the front, then disconnecting the 12V battery ground, wait a few minutes, then reconnect 12V and loop. That will give a full reset.

I was asking the OP?

This would be my first step before getting the car towed to tesla.

Is the main screen on and functional? or off and black?

How can you tell if the 12 v battery is beat?

Nothing works, no lights or such.

Gotcha

Does the 12v battery power that initially, if it is dead, then what will work.?

The 12V battery powers the main battery contactors. Without it, the car can't fully power up and can't move.
For S/X, the 12V charger is after after the contactors, so without 12V, the 12V can't charge.
For 3, I think there is a a separate 12V charger port on the pack, so it can charge the 12V battery without the main contactors active...
