12v battery died in 1 night, car auto heat-up?

[VTompson]

Hello guys!
Just bought tesla model S90D 2017 from USA(I am in Ukraine)
First few days I've noticed my cars interior temperature is always higher than outside(eg. outside is +5, and car is +16 in the morning).

All climate options are off, double checked.
And on third morning my car "died", no reaction on key whatsoever, so I called technicians, and they started my car with external 12v battery through a hood.
Cabin overheat protection was on, when this happened, my "service station" gave advice to turn it off.
HV battery was almost full at that moment.
But they haven't found any reason for 12v to be drained overnight. So they charged my 12v and returned car to me.
Now I am afraid of this situation could happen again
Help please!

How has it been the last few days with Cabin Overheat Protection off? Can you ask them to check the logs and the 12 V charge level? You can do this through the Tesla app.

Congrats on your car!

hello mate, it haven't discharged anymore(2+ weeks now), but few days ago "12v battery must be replaced" appeared so I'm going to change it.
You mean send a request to tesla service for logs? doubt they will check Ukraine car^^

I wonder if the 12volt was heavily discharged during shipping. Draining to completely dead is hard on even regular ICE batteries.

well, the car is 2 years now in Ukraine, so probably previous owner killed it

I presumed it arrived more recently.
The 12volts only last 2-4 years in a Tesla, the way they are used is much different than gasoline vehicles.
I would just replace it.
