general problems of the 2006 Mercedes Benz E55

Leaking gas into car cabin. . . . Apparently this is a well known and documented problem. We are taking the car to the dealership tomorrow.

I am getting a strong gas smell from the car when standing outside of the car with it running and long after the car has been shut off. If I park the car in the garage after a drive and then come back to it 30 minutes later my whole garage smells like gas but cannot see any leaking.
