    The other day, I was very slowly backing out of my garage and the car jumped into park. This is not the first time this has happened to me... at first I thought I must have hit the shifter... but, this was not the case. I asked the service mgr and he was unaware of any related software problems.

    Wondering if anyone has experienced this?

    Thanks in advance.

    You might have lifted your weight off the drivers seat sensor. Are you using your backup camera/mirrors or are you turning your head around to see behind?

    This happened to me once before. My seatbelt was off and I lifted off the seat a little bit. There's a thread on the forum somewhere about it. Some kind of safety feature.

    Here's the butt sensor thread. Shifts to Park when Butt Lifted from Seat?

    Same 'safety feature' that allows you to simply get out of the car once positioned in a parking spot. It automatically puts it in park when it senses the driver is no longer there.

    I had something similar happen, but I see it as a feature not a problem.

    In my case I was in my Model S without the seatbeat fastened and with the drivers door open. The car of course nagged me about the seatbelt then I started backing up. After I exceeded a couple of miles per hour the car automatically shifted into park because I was driving without a seatbelt and with the door open.

    I realize you live in year-round convertible weather but this is ridiculous. You Florida drivers are crazy. ;)

    For the record I consider the winter as convertible weather. While it is true that many Florida drivers are crazy, or at least not entirely lucid, in the unlikely event that you are serious, I was merely repositioning my car in the driveway, not heading out for a drive. :tongue:

    This happened to me today. I was backing into a tight spot, my seatbelt was OFF, I looked back because the camera wasn't giving me a sense of where the pillar was. I must have lifted off the seat. The car automatically went into park. It happened twice in a row and happened a few days ago. My car is less than 2 weeks old so has the latest software.

    Quite common if seat belt not on and/or a door is open. It usually happens at low speeds as well.

    That's expected behaviour.

    It happened to me a few times early on. Very unsettling. Now I always make sure my seat belt is buckled, even when just repositioning the car. You can lift off the seat to look around if the belt is latched.

    Whenever you are in a vehicle that isn't parked!

    Backing through the garage door opening with your rear passenger door open is not advised. It leaves a mark. (Fortunately, I don't have first-hand experience of this).

    Sometimes it leaves a mark on the garage door and not the car. I was once replacing the brake pads in my first car, and when I completed the job I forgot the all-important task of pumping the brakes to extend the piston and pad to the rotor surface. Put the car in reverse while holding the door slightly open and when I put my foot on the brake to stop the car, it went to the floor. Car kept going and the door contacted the 2x8 that framed the garage door. It popped off as the car kept going. No damage at all to the car, I got really lucky that the broad surface of the door was positioned perfectly to pop that frame out.

    It's happened to me as well...thought something was wrong with the car until I put my seatbelt on!
