Gas door of the 2007 BMW 328xi (and others) can become open & ejected at highway speeds, or during car wash. The door unlocks & can be opened when force is applied if both car doors are unlocked. If enough force (lateral) is generated during a wash, or at highway speed, the door can become ejected due to blowers (dryers) of car wash. Good intent, poor execution by BMW engineers by using a snap fit plastic door assembly w/ the sheet metal door.

I drive a 2007 BMW xi and it is less than 1.5 years. This is all about a week apart from each incident. The had been acting funny for a week or so and I brought it into BMW and they found nothing wrong. They gave me back the car and a week later, the car stalled on me while I was driving. After taking the car to the dealership, they discovered the fuel pump needed to be replaced. I picked up my last week and this week while driving home from work, it stalled again! most likely due to the fuel pump.
