    I have about 800 miles on my TM3 all with the 10.5 update. I just updated to the 2018.12.1 just now.

    Anyways this has happened 3 times to me in about 2 weeks. I'm in reverse moving very slowly when all the sudden it comes to an immediate stop and it shows it's in Park. It's kind of alarming because it happens unexpectedly. Anyone else with this issue?

    Are you lifting yourself out of the seat?

    To add to this: do you have your seatbelt unbuckled when reversing? Both things will cause the car to do that, at least on the S.

    Also, is a door open?

    Nothing wrong with your 3. That's a safety feature.

    Thanks for all the responses and the other similar threads. I never received any error codes and it never said to pull over or that anything was disabled. I just put it back in reverse and it was fine. Based off the comments: 1. no I didn't lift myself up from the seat. 2. All doors were closed. 3. I was NOT buckled so I'm thinking that might be the cause. I'm the type to pull out of a drive way and when I go into drive I then put my seatbelt on. It allows me to save a whole 2.3 seconds :). So from here on, I will buckle first and see if that does the trick. Maybe that explains why it never happens to my wife because she always buckles first.

    I had the same issue when rolling very slowly in both reverse and drive, and I think it was a combination of raising out of the seat and not buckling the seat belt when I was moving the car around my driveway. It's actually very easy for me to reproduce without a seat belt and raising slightly out of the seat (say, if you're turning around to look behind you as you reverse). No longer happens once I started paying attention to those two things.

    It doesn’t take much seat lift to auto-park the car. sometines just a weight shift.

    Putting the seatbelt on overrides the seat weight sensor.

    Reason is because if you’re not buckled, you’re in reverse, and you accidentally press the accelerator too hard, you’ll move forward toward the windshield, probably causing you to push the accelerator harder and you’ll immediately be dangerously out of control and pushed against the dashboard.
