    Updated to 2.32.23 overnight. While backing out of the garage the next day the car put itself into park after about 3 feet and displayed the release notes. I closed the release notes on the screen, put the car in reverse and continued backing out. After another 3 feet or so the car again put itself into park and displayed the calendar. I closed the calendar and finished backing out. Filed a bug report.

    Thanks for your post. Yes, it sounds like a bug, but just wanted to point out (and apologies if you already know this) but if while backing up you inadvertently raise up slightly off the seat, enough so the seat sensor no longer detects your weight, the car will automatically put itself into Park. Sometimes while backing up some people lift up a bit while turning their head to look behind. I am guessing you are a relatively new owner (based on the refreshed S shown in your avatar photo) so perhaps you are not aware of the seat sensor behavior.

    That said, I am in no way questioning what you describe in your post. It is entirely possible that what you describe is a new bug associated with that firmware release.

    Did you have one of the doors even slightly ajar? The safety of the car will stop it and put it in park if you are trying to move it if its in drive or park and a door is open - even just a little bit.

    One way to avoid this is to put your seat belt on before backing up.

    that happened to me as I was backing out of my garage yesterday. I thought it might have had to do with getting too close to the garage wall while I was backing out.

    Thanks for the reply. I did hear about the weight sensor issue but in this case I was not turning around in the seat. I use my mirrors and the backup camera when I reverse out of the garage. I think it is a new bug but it hasn't happened since this morning and I've been out and about in the car all day. Fingers crossed.

    I thought the same thing at first as the sensors always beep when I pull out of the garage. However, as far as I know, the car will not forcefully put itself into park even if your about to hit something.

    You can contact Tesla service and tell them what time it was at and they can check the logs to see what exactly caused the vehicle to put itself in park

    I had this happen a few days ago on my "classic" S. It hasn't happened again since.

    Wear your seatbelt and don't lift up out of the seat, use the backup camera. It's not a bug.

    There's a song title if I ever heard one. Or poetry...if the board is the in mood for it...

    I did and I don't and I do.
    Yet my car stops backing,
    While the seatbelt ain't lacking,
    And my butt was quite comfortable too!

    Then it's a bug, you should contact service about it.

    I had a similar incident backing up in an underground parking garage. I attributed it to a dirty sensor that may have tripped the auto braking function. You can shut off the auto braking for a test.

    I can image this being pretty scary to think that at any moment your car might go into park. I would for sure let Tesla know of the day and time it occurred so they can check the logs and get the bug fixed. I am guessing it was a sensor malfunction and the car being to close to something and it felt it needed to stop the car to avoid an accident.

    Keep us updated...

    I reported it via the "bug report" voice command right after it occurred. Hasn't happened again. Fingers crossed.

    Sounds like the exact behavior I get when backing out of the garage with my door open. Since your door was closed, maybe its a door sensor that happened to go bad around the time of the software update. Stranger things have happened.
