Cracks at the top of the fuel sending unit cause fuel to leak out after filling tank. Fuel smell in cabin extreme, fuel then leaks out near left rear wheel and pools where parked. Certainly a safety issue!

Reference pe12001 & ea13003 after filling up I smelled a strong gasoline odor in the car. Upon further inspection, the odor was coming from the rear of the car. It smelled like the drivers side rear seat cushion had been soaked in gasoline. The odor was so strong, driving the car with the windows up was impossible. I did some research online and found out that this was a common problem with the mercedes amg cars. As instructed online, I removed the seat cushion opened an access panel and could see liquid gasoline pooling on top of the fuel level sender unit. I could also see where the unit had cracked, allowing gas to escape the tank. I contacted mbusa about this problem and they advised me to see the dealer. As expected, the dealer diagnosed it as a faulty fuel sender unit. They contacted mercedes on my behalf to attempt to get assistance with this repair. Mercedes denied all assistance under the standard and emissions warranty leaving me with over $1000 in repairs. In 2009, my car was previously repaired under recall #2008-020001 which was supposed to fix this problem, but it clearly failed to fix the problem permanently. I had to get my car repaired by a third party repair shop and feel disgusted by the mercedes inability to fix such a faulty and serious design flaw. They would rather make their customers pay $1000-2000 to avoid passing out from gasoline fumes or risk being killed in an explosion from a collision.

Gasoline leak creating extreme odor inside and around car exterior. Dealership states fuel sending units and tank need to be replaced at my expense. My car was included in the related recall #2008-020001 and was subsequently serviced at dealership 1/19/09 to address the issue. Obviously the proposed remedy was ineffective. According to testimony of hundreds of other e/cls owners with identical, persistent issues- this is a definitive design issue and has created a serious safety and health issue that requires mb to sufficiently rectify once and for all.
