First it won't turn on, now it won't turn off

Not sure what that is but I'm on 26.3. I have Summons and it works well.

Battery Management System (BMS) Bootloader Update

Does this fix the battery fan and interior over heat fan from running all the time? Ours didn’t turn off for a month during the last go around. Not to mention the HVAC having a mind of its own and the car not waking up even after you tap the screen, select drive and press the brake?

Thanks for the link. I'll request the boatloader update be performed when I take the car in for service.

I just picked up ours and can’t get the car to shut off. Unpaired my phone and locked the car with my card but the car stays on. Can’t open the charge door from the screen or my app. WTH!!!!

Sounds similar to the issues I've been having. You can reset the software but I doubt it will solve your issue.

Carrera, does your brake lights stay on while this is happening? All three of my brake lights will stay stuck on. Makes me wonder if the brake signal isnt turn off even when there is no pressure, so the car thinks its on.

No brake lights on my car. Earlier in this thread are procedures to reset using your steering wheel controls. Try that.

I’m having this problem Car won’t turn off, tail lights are on, headlights are on, brake lights on or occasionally flash on/off, screen doesn’t shut off when I leave car and close the door, locking it from outside doesn’t close the side mirrors. When I manually open charge door and plug in, an alert comes on screen saying it can’t drive, check charge port. It basically thinks someone is in the car.

It doesn’t always happen, but is happening more frequently now.

@SJC3 did you make any progress with resolving this?

Yes, it took two visits, but I eventually told them it’s likely the brake light switch on the brake pedal. They took a look at it and made a quick adjustment and it was fixed. Basically it was getting stuck in the on position, so the car would think that I was pressing my foot on the brake pedal.
