Other Fuel System Hoses Lines/piping, And Fittings problems of the 2010 Mercedes Benz E350

Request NHTSA 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 NHTSA 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.
