C55 amg gass cap lock broken
I've had a somewhat similar problem, and it was the fact that the gas cap door couldn't close properly. Upon closer inspection it was due to the bent lock tab (the part that sticks out where the lock bolt goes through)
Anything can happen to a car, however, I remember in NJ most gas stations are Full service. IF you had put gas in your car in the weeks prior to your incident, it is very possible that the attendant tightned the gas cap wrong on the thread it could have easily broken off (the cap is not a metal piece)
I used to travel a lot to NJ and I have seen how gas stations work there...
