Fuel Hoses Lines/piping And Fittings problems of the 2007 Mercedes Benz E350

Smelled gas inside vehicle after filling up, engine light came on, and the smell was extremely overwhelming with gas fumes. I had to roll all windows and sunroof down in 20 degrees weather. Contacted Mercedes Benz atlanta on piedmont (all records on file with up keep of vehicle maintenance) to advise. First available appointment was Tuesday 8 am. Took the car to be repaired and I am stuck with a $1400 repair bill. I was told by my service advisor that in 7 years the fuel pump goes out and has to be replaced? really mercedes? this is a manufacture defect and the consumer should not be held accountable for something this major. So much for high end top of the line. This is certainly a defect and needs to be recalled immediately. I want my money back and mercedes need to send my check immediately. I will think long and hard before I purchase another mercedes since this is the normal expectancy for mercedes upscale performance.

This is the second occurrence. Dealer replaced engine once. I reported the first incident on confirmation number (odi number) 10507237. This second incident occurred on or about 13 July 2013, car started having illuminating odor in the cabin again that resembled fuel. Garage and car odor was so bad it actually entered my home and I had to leave the garage door open to ventilate. Went on line and found other owners exhibiting exact defect. Took vehicle to mercedes dealer and was informed that a leak from the fuel tank was the cause again and it was not from damage but from the sending unit and lines. After reading the warranty and contacting mercedes directly, I contacted the dealer and informed them that it is a covered item and they should make the repair as a warrantied item. I am making this complaint because I believe that the replacement unit will be the same oem part that has not been modified to solve this failure from duplicating later.

Shortly after we purchased the car on 3/13/2013 we noticed that after we filled up the car there was often the smell of gasoline. This never occured when the gas tank was not completely filled. After a number of times investigating this smell, our auto mechanic was finally able to determine that fuel was leaking from the center vent connection of the tank. The fuel tank was removed and they found theleak around the center vent hose connection. The fuel tank and seals were replaced on 8/30/13. Updated 9/24/13 updated 12/05/13.

The contact owns a 2007 Mercedes Benz E350. The contact stated the fuel tank failed. When the fuel tank was full the fuel fumes penetrated the vehicle and the trunk area. The vehicle was taken to the dealer where a diagnostic test was performed which located the failure within the fuel tank vent hose which was made with a defective plastic liner, and caused the fuel to leak. The vehicle was repaired. The dealer replaced the fuel tank. The failure and current mileage was 72,000. Updated 02/15/bf the leak was coming from the gas tank vent hose. Updated 03/26/12.
