1 Tank Mounting problem of the 2004 Mercedes Benz E55

Failure Date: 10/09/2013

Every time I fill the gas tank there is a strong smell of gas fumes inside and outside of the vehicle. It is nauseating and seems would be dangerous. The dealer states a test verified a leak at the left pump housing area. Additionally found staining at the top of fuel tank near center mounting area. They recommended a replacement of the fuel tank assembly with new pump and sending unit/filter assemblies. This repair is $3000 us. The problem is the new equipment is the same faulty design of the original equipment. Most likely the same problem will occur again. After checking out the situation I have found this is a common occurrence with this make and model and that the manufacturer is aware of the problem.

2 Tank Mounting problem of the 2004 Mercedes Benz E55

Failure Date: 05/01/2010

Fuel tank leaks fuel onto the ground via the external inter tank transfer hose on the top of the tank. To repair this mercedes has to replace the tank which requires a complete teardown of the rear suspension and rear subframe. I brought the car to the dealer for this issue 5 times, any time the tank was greater than half full it would leak a significant (a puddle formed) amount of fuel on the ground. Mercedes benz did not warranty this issue stating that they have never seen this issue and it was a one time thing, even though they "repaired" it five times.
