I first noticed the problem around March 2026. When I fill the fuel tank of this 2007 Mercedes-Benz E350, gasoline pools on top of the tank beneath the rear seat, inside the passenger cabin. I have breathed gasoline fumes from it. There was no fire or crash. An independent Mercedes specialist's records include a March 2026 recommendation noting a very fine EVAP leak at the fuel tank and/or vapor line and that the tank is no longer available. On May 29, 2026 (65,138 miles), with the check-engine light on and a strong fuel smell inside the vehicle, the shop replaced a leaking left fuel pump and seal. A fuel-system test that day indicated further checks were required. The gas pooling continued after the pump was replaced. On July 28, 2026 (66,067 miles), the shop noted that the fuel tank is warped. I wrote to Mercedes-Benz USA on October 13 and October 16, 2026 with my service records and have not received a response.

Gas smell in the cabin by model year
What owners say
Recently my wife and I noticed a very strong fuel smell from cabin of this car. When I inspected and lifted the seat there was a puddle of fuel leaked over the sending unit. This is extremely dangerous and potentially deadly for my family especially with 2 young children who are always seating in back seat. Upon checking with Benzel Busch Mercedes dealer in Englewood New Jersey, they said they cannot fix my issue because my warranty has expired. I am now writing to you to help me as I feel this should strictly be a recall and Mercedes USA should be required to fix this leak free of charge. Please understand that out of pocket will be more than $8,000 for this repair and I do have the means to come up with that amount of money. Upon checking on internet there are many E class Mercedes Benz between years 2003-2009 that have this issue. Could you please help me resolve this matter especially this being an extremely dangerous situation. I can be contacted via email: [XXX] or phone: [XXX] . Thank You Sincerely [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The contact owns a 2007 Mercedes-Benz E350. The contact stated that while refueling the vehicle, the vehicle emitted an abnormally strong gasoline odor inside and outside the vehicle. The vehicle was taken to the dealer and the contact was informed that the failure was related to an unknown the federal safety agency ID Number; however, the campaign had expired. The vehicle had not been repaired. The manufacturer was made aware of the failure and referred the contact to the federal safety agency Hotline. The approximate failure mileage was 77,000.
Fuel smell coming from the rear, car is a pzev and out of warranty, smell is very strong and I am unable to drive it with a child in the back because they get dizzy. Unable to fill up with gas up to a certain point or smell will linger.
Fuel tank and fuel parts leaking. 2 repairs and car often smells of gasoline especially in the garage.
Fuel tank fuel leak, the federal safety agency Action Number EA13003 I purchased a 2007 Mercedes E Class used a few months ago, and recently I noticed a fuel leak, strong fuel smell outside of vehicle when fuel tank is filled higher. More fuel means more fuel odor. Upon research, it seems like there was a warranty extension for 15 years, and with my luck, warranty extension ran out just after I bought the car but before I noticed the problem. As fuel is a safety issue and can easily ignite, and also affects emissions, I feel like the remedy should not just be a 15 year warranty extension, but longer as cars are staying on the road longer and longer. I'm sure I'm not the only one with this issue out of warranty extension period.
The component/s that have failed are (reputedly) the fuel system resulting in significant fuel fumes permeating into the cabin of the vehicle as well as being very evident around the rear outside of the vehicle. This seems to be more obvious after the car has been filled with fuel. Having fuel fumes leaking into the cabin of the car should be self evident as a risk to anyone travelling in the vehicle, especially in the rear seats. The fumes eminating from the car, externally, are a potential fire hazard should anyone walk by with a cigarette or naked flame. This is an on going problem well known to Mercedes Benz and one that should have been the subject of immediate recalls by MB and not subject to a Mileage, Time Frame or VIN number. Why should I, or anyone, have to foot a fairly significant bill, for fixing a manufacturing fault just because the previous owners didn't get the problem fixed and I purchased the vehicle after some 15 year warranty time frame? This issue could result in someone's death if Mercedes is not forced to remedy it and by remedy it I mean for ALL 2007 E350's to be recalled unconditionally. Consumer would like to amend the complaint to include the recall of ALL Mercedes E350 for the years 2006 and 2009 for inspection of the cause of the problem and the repair of those vehicles where repairs are needed at Mercedes Benz cost.
After I filled up my gas tank and came home and parked my car in the garage. After a few hours I smell strong gas smell. When I researched mbworld, I saw many people having the same / similar issue, and mercedes benz had extended the warranty to 15 years towards fuel leak issues. There were many articles on the forum. When I called my dealer, he said that I there are no recalls on it. How do I resolve this issue?
When I fill up the gas tank I notice a gas smell from outside of the car on the rear drivers side. When the fuel level drops to 3/4 full the smell disappears. I'm afraid of an explosion if I park in an enclosed garage
I recently bought an 07 mercedes e350 I've found this same complaint on numerous websites the whole cab of the car fills with a terrible fuel smell only on the inside of the cabin but its so bad id hesitate lighting a lighter in the car until the windows have been rolled down and aired out its supposedly under the very spot my 5 year old granddaughter would be seated this is not only highly dangerous and flammable but will give the driver and occupants terrible headaches, nausea at times and in my opinion is a not only fire hazard but also a health hazard and it does this sitting stationary without the car running I've tried everything not filling the car to the top but even at a half tank you have the same problem its so bad I would return the car if the dealer would take it back this is extremely unhealthy
