One problem related to fuel pump has been reported for the 2007 Mercedes Benz E550. The most recently reported issues are listed below.
Very strong smell of gasoline outside the car when parked; and inside when driving or when stopped while driving slow. This happened a day after servicing the car transmission at the same dealership. Took it back to dealer, they claim it's a very common issue and the car is hazardous to drive because gas leak is on top of exhaust and can start a fire. It needed $3,000 repairs (gas tank + fuel pump & sending unit. ) I was driving a time bomb with my children the night before without realizing it. There should be a recall for this dangerous factory dangerous design & poor engineering quality of gas tank.
