I drive my SO's Model S a bit - by myself and together. Several times we have returned to the car with the rear passenger door unlocked and ajar. We were curious if one of us wasn't closing it properly or someone else/something else was getting it to open.

Five minutes ago I parked and then fiddled with the sun roof ('vent' is too closed, 20% was more open than I wanted). I noticed I was still in 'drive' and put it in 'park'. I heard a noise - it does that sometimes when putting it in park and I don't usually pay close attention. This time I investigated - the rear passenger door had just opened itself.

I closed it, put the car in 'drive', creeped a foot forward, fiddled with the sunroof and then put it in 'park'. Nothing.

I put the car in reverse, backed up a few feet, drove forward a few feet, fiddled with the sunroof and then put it in 'park'. Also nothing.

Anyone else come across this or know what the repro steps are?
