Door won't stay open.
 

It's laundry day and you open the rear door. Then you turn around and grab the basket with both hands and you've found the door has shut all by itself. This is a very irritating fault of my car. It is unclear if this is by design or a mechanical fault.

If you're in your parked car and feel a nice breeze that feels better with the door open vs the window, you open the front door. Then it just falls closed again. Am I the only one with this issue? It closes on a flat square of ground. My 330i doesn't do this, nor did my Ford Tempo.

My driver door does it, the detent on the hinge is worn out
