Seat heat stays on after restart

[Billee]

If I manually turn on the seat heater without turning it off prior to shutting down the car, it will come on again at the next startup. I assume this happens on all model 3's. If this happens with the passenger seat, you might not notice it's running for months if no one uses that seat.

Note: I checked that it's not the automatic mode coming back on.

My experience mirrors yours in that, that is one of the settings that stays how you set it, and persists until changed (like other HVAC settings, and a few other things).

The icon for seat heating will show in the app climate section, as well as the climate section in the car.

I think there is an auto setting somewhere in climate. Had the same issue and resolved once I figured this out and also remember to turn it off after disabling this function.

While it does mean that you have to be aware that it could happen, I view this as an important feature here up north. Basically my seat and steering wheel have been left 'on' all winter

I think the passenger seat needs to be occupied for the seat heater to come on.

I think that's true for automatic mode. I just tested it in manual mode and it heats up with no passenger in the seat and stays on after restart.

The auto mode works fine for me. I leave it in auto all of the time. Of course YMMV.
