This is in regard to E350 2010. Gas smell after tank fill up (only when full). Fuel pump cover on the driver side under the back seat. The tank cover (plastic) breaks and leaks. Similar problem was noted on previous models (2009) and recall was issued. [XXX] Very hazardous (Flammable and combustible) and the dealer stated that it is a common problem. I removed the back seat and is gasoline leaking and accumulating above the cover. Similar problem occurred on the cover on the right side and was replaced. The plastic cover on both sides breaks and leaks gasoline into the car. Should be recalled and replaced. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Request the federal safety agency immediately re-open the investigation of mercedes-benz' deliberate & continued use of defective fuel system components. The warranty extension offered by mb for 2003-2009 e-class sedans on fuel tank components, including fuel tank, fuel filter/sender, fuel pump & related gaskets/seals/retention rings, is not sufficient. Please require mb to extend the warranty to later model yrs & all e-class vehicles such as 2-dr coupe, not just the sedan. My vehicle has only 48,000 miles (driven <7,000 mi/yr) & fuel sending unit closing cover is now leaking. Gas fumes/leakage is so overwhelming that car cannot be driven or parked in a garage. Driver is in eminent danger of car bursting into flames if a spark or match is lit nearby. Plus owner risks damage/theft/bodily harm now being required to park on street rather than a secured garage. I've owned 8 other vehicles in my lifetime incl. Fiat, oldsmobile, ford, toyota & lexus. Never has any other vehicle had this problem. Plus several were 2x+ the age of this car & had 2-3x greater mileage. This fuel system problem is not caused by normal wear-&-tear or any fault of an owner. Repairs must be mandated by the federal safety agency to be covered by mb due to fact that they have continued to use defective design & defective components, even knowing for years prior to manufacturing 2010+ models, this issue exists. The mb dealer wants to charge $1133.89 plus tax for the initial "closing cover" repair & will not guarantee that will even fix the problem. It may cost thousands more to have the entire fuel tank replaced if necessary. I implore you to seek justice for consumers like myself, harmed by mb's defective fuel tanks that allow fumes to seep into the cabin & broad area surrounding the exterior of vehicle, plus liquid fuel to leak on the ground. Please relpy with specific action I can take to rectify this deplorable situation.

The engine ceased to have power and stopped on the freeway in commute traffic. The gas tank had more than half a tank of fuel. The fuel tank in this model is under the rear seat. Because the drive shaft and differential are in this area the gas tank is in two sections but connected. There is a pump in one section which transfers fuel to the other section when that section gets low. The pump failed and stopped transferring fuel. The mechanic had never seen this problem. A new fuel pump was ordered from mercedes in los angeles as the car was too new to have the part locally.

This complaint is for a 2010 bmw 535i xdrive. I went into the garage to start my car this morning wednesday, 10/28/09 and the check engine light came on and the car started shaking. I moved the car out of the garage and shut off the engine to see if it would reset, I started the car up again and the check engine light was still on and the car continued shaking, I drove the car about 50ft to see if it would stop shaking and light would go out but it did not. I drove the car back into the garage and waited about a 1/2 hour to try it again it was the same problem. I contacted the service department whom advised me to contact roadside assistance to have the car towed in because it should not be driven. I had the car towed to open road bmw where I had purchased the car from two (2) months ago. I spoke with the service advisor and asked had anyone else experienced this problem he said yes on the 2009 and 2010 models it seems to be the fuel pump. There seems to have been a problem with them, but once they have been replaced that seems to have fixed the problem. I am waiting to hear back from the service department.
