The problem with Tesla cars is that they uses two batteries. One is the main one, which is used for propulsion, and the other one, a conventional car battery, is used for most of the critical electronic.
Problem is, both are independent from each other, which mean you can have a full main battery, and still be locked out of your car if the secondary on is out.
You can have a similar results with gas car, where the ignition won’t happen because of the cold, but at least you can recharge it easily with another car that happens to pass by. For Teslas, you can’t. Because those fuckers decided that it was too unsightly to see the bare battery, and bolted a plastic turd over it to make sure the only person to ever be able to change it is a Tesla tech.
All other car manufacturers, which happens to have a bit more experience than those asses, understood that being able to have an unified battery, that happens to be thermally insulated (and often in the nordic countries, heated), to make sure you actually use them, even in cold weather.
Tesla cars are a perfect example of a product that only survive out of hype. They are overall badly designed, arguably ugly, their only redeeming quality was their autopilot, but even that is starting to crack.
It's true, our plain old dinosaur fuel car was notably slower in turning over on the -5 and colder days we've had recently.
But since tesla bother to heat the propulsion battery why don't they either 1: have a 12v power supply to provide ancillary power from the propulsion batteries if the 12v supply fails, or 2: also heat that battery too?
Probably due to the legacy of their first car, which was a gas car (a Lexus if I recall correctly) converted to a fully electric car. To minimize what they had to change, they kept the electronic circuitry as is and just changed the propulsion. Problem is, a gas car has its internal engine to heat up the battery. Electric car doesn’t.

My Kia also has a normal 12v battery for normal car stuff in addition to the main battery pack. But it uses the main battery to charge the 12v if that ever gets low while parked

And that a simple trick that Tesla still don’t have implemented, to my knowledge.

That is false. Teslas maintain charge on their low voltage battery from the high voltage battery, just like every other EV

It is a good thing they changed then. I have multiple acquaintance who own Teslas who got locked up of their car because of the lack of this feature.
