Front passenger and rear window opened by themselves

Today I parked the car in 'camp mode' for a few minutes, when I got in, closed the door and...the front passenger window and rear driver side windows went down by themselves.
My daugther was in the car with me and asked me why I rolled her window down :) I found one of the rear windows down before, but thought that I had inadvertently leant on a button getting out.

Has anyone else had this happen?

The problem comes and goes. I had it a lot when I got my car in 2019, seemed to go away for a while now it's back. Tesla implemented a bandaid solution that mostly deals with it. Now when the car locks itself it automatically rolls the windows up.

I have that setting enabled as well. This happened yesterday when I got in and shut the door, not when I got out and walked away. I defintely did not brush the switches, would have been tricky to do windows diagonally across as well.
I have an appointment at the SC in two weeks time, might as them to look at it as well. Maybe a loose connection or something. They are replacing door cards anyway as these were damaged by the protective film being removed prior to picking up the car in December.

I had a ranger service call for this when I first got the car, the guy looked at the logs and found nothing, said it was software than did nothing. You can try calibrating the windows, seems to help a bit. My suspicion is that the cause of this is that windows are rolled down a little when you open the door and roll up again when you close it, something seems to go wrong with the process. It's definitely has nothing to do with touching buttons, I've seen it happen where opening the front passenger door rolls down the back passenger side window. The driver's door has controls for all four windows but the passenger doors only have controls for their own window.

I was convinced I had this problem for a while but eventually I realized I was inadvertently depressing the window switches with my hand/arm.

I had this happen twice - in a downtown parking garage. Came back to the car and the front passenger window was down. Luckily nothing was taken of or screwed with. After the second time in a few months I wrote it up, mobile service came and replaced the front passenger window switch. Hasn't happened since.

And people saying "oh I bet someone hit the switch with their finger getting out." Nope - we certainly know the sounds of a window going down and the car door shuts much quicker with the window down (less air resistance). It would of been noticed.

and also the window is usually 1/3rd to 1/2th down, which takes a longer press than a momentary accident

Happened to me yesterday, passenger side window went down when I got out of the car. Rather then wait of the car to lock on it's own I locked it with the app, the window went up when I locked it. Putting the windows up when locking is Tesla's work around for this bug, would be nice if they found the real cause.

Some of this happens automatically when the outside temp is around freezing or lower. The car automatically keeps the windows lower in case they freeze to the seal when you open the door. There's less chance of the window hitting the chrome (or blacked...) top trim. Surprises a few people.
The other cases for me was because I inadvertently touched the window switches as I was opening the door. Sometimes it'll be the back windows, sometimes the front. It took me a while to realize it was of my doing. Maybe you could say the switches are not well positioned relative to the "door open" button and how you hold the door handle inside to push the door open...
My impression is that this is what happens to most people that report this, they just haven't realized it yet.

I think I've got a clue as to what's going on. It may have to do with unlocking the charge door. I just did a very short trip, a mile, with the windows open. Got home, closed the windows and I even held the buttons closed for 10 seconds to calibrate the windows. I got out of the car, grabbed my charge cord and pressed the button to open the charge door. After I plugged in I walked around the car and the front passenger window was open.

I kept brushing against the switches also and finding the windows down slightly on return (always passenger side due to location of switches. I just enabled the rollup windows on car lock option and haven’t seen them open since.
