Three problems related to other fuel system tank mounting have been reported for the 2007 Mercedes Benz E350. The most recently reported issues are listed below.
I have been reading all fuel related complaints regarding my vehicle and its overwhelming the amount of complaints over the same thing. I have a gas odor in rear left side of vehicle after I feel my car. My certified mercedes mechanic inspected the rear seat are and notice fuel at the sending unit on top of tank. Mercedes benz says my VIN is not part of the extended warranty but yet I have the exact same problem that those non pzev vehicles. Is there some kind of ruling or agreement says mercedes needs to resolve this problem??.
2007 mecedez benz E350 noticed strong fuel/gas odor inside car after filling up gas tank and would subside after gas tank was approximately 3/4. My children & I had to roll down the windows while driving due to feeling nausea. This has occurred often for weeks. Last Thursday on 8/7/14 I was driving vehicle coming to a signal light at an intersection and the car started shaking like is was loosing power, then it shut off in the middle of the street at the intersection. I tried starting it back up and it would not start at all after cranking for few seconds looking like it was not getting fuel at all. I had to get my car towed, the mechanic said it was the fuel pump and it will cost $2000 to replace. This seemed extremely hazardous for car safety having to smell the fumes and almost causing an accident. There have been an enormous amount of complaints regarding the fuel emission pump/tank & this manufacture defect of the car which is a major road safety hazard item should be considered as a safety recall from mercedes car company.
Filled gas tank and parked car in garage. The next morning there was a strong odor of gasoline in the garage. Looked into problem and found a problem with the gas sensing unit on the left side under the rear seat. Found the large nut loose and tightened. Filled gas tank again on 4/21/14 after partially filling in the interim. The next morning the garage had a gasoline odor. Removed seat and found the entire area was filled with gasoline, probably about 100 cc. Removed gasoline and drove 50 miles. Returned car to garage. After four hours gasoline odor is in garage and the sensing unit is damp with gasoline. Called mercedes dealer and set an inspection date.
