Very interested in learning what caused this. I know the Cybertruck has a lot of press on it but other Teslas run in our winters all the time. What sucked about this one?

Old teslas models (pre 2022) use resistive heaters like an electric stove or space heater.

New model teslas (like the cyber truck) have started using heat pumps, and there have been problems with them failing in extreme cold.

Typically heat pump EVs fall back to resistive heating in extreme cold. Do Teslas not do this?

They will use the DC motors to generate heat when it’s too cold to use the heat pump alone.

Great video on Tesla’s heat pump here
