“Whenever I fill the gas tank full with fuel, there is an over whelming smell of gas in the garage. There appears to be a leak when the tank is near full. Once I drive the car around for a while, the smell of gas goes away.”

“My vehicle is a 2006 mb cls55. After filling up my vehicle with fuel, I noticed a leak in my garage and a strong odor coming from inside the car both while running and while shut off. I brought my vehicle to an independent mechanic and verified that both fuel pumps are leaking from the top. These leaks result in a pool of fuel directly under the rear seats. I received a $2,200 dollar verbal quote from a dealership to replace both fuel pumps. They advised that this was a common problem with all 55 series vehicles.”

“The vehicle was sended to inspection due to a brake warning started showing at the gauges control panel. Mercedes benz dealer service manager indicates that they not have a correct tool to recode to actualize the brake system and /or fix the problem at that time. Three visits and several phone calls been made to the dealer. The service advisor is always with other customer. I'm stop to drive my vehicle, because I never knew how deep is the problem. Doing a visual inspection I observed that the rear brake pads are not applying good enough, the surfaces of the rotors are different. …”

“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. …”

“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.”
