What owners say
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.
The contact owns a 2014 Mercedes-Benz E-Class. The contact stated while driving at an undisclosed speed, the contact noticed fuel odor in the interior and exterior of the vehicle. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The dealer was made aware of the failure. The contact referenced an unknown recall; however, the VIN was not associated with a recall related to the failure. The manufacturer was made aware of the failure.

The failed component is a fuel pump, and it is available for inspection upon request. My safety and the safety of others was put at risk due to the following: 1) Sudden engine stalling 2) Dangerous power loss while accelerating 3) Potential fire risks; a damaged fuel pump assembley can cause fuel leaks and overheating due to insufficient fuel supply can increase the risk of explosion or fire. 4) Gas fumes from a fuel leak are highly harmful and dangerous. They are toxic to inhale causing dizziness, headaches, nausea or respitory issues.
Strong smell of fuel from the rear wheel well areas, especially after a fill.

Fuel odor is very apparent (while idle) but difficult to identify location. Same models seem to have recalls for fuel injectors/rails but not this specific VIN. I believe the issue might be of similar recall. I will have the car diagnosed soon.
Fuel smell in the rear of the car, it was checked by a indepent mechanic and the tank is leaking fuel. They said is the Fuel filter which is usually faulty in this model. It seems the car can catch fire according to the mechanig. No warnings of the leaking in the dashboard, only the strong smell.
A gasoline smells fills the cabin and the outside surrounding area the vehicle continually to the point making anyone surrounding the vehicle and or sitting in the front and back seats physically sick. The gasoline smells omits continually from the backseat and or trunk area no matter the amount of fuel that is in the tank. It is a fire hazard and also health hazard as well.

- What is wrong
- Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2014 E350 and E350 4Matic sedans manufactured June 4, 2014, to July 9, 2014. The affected vehicles were built with a fuel feed line that has a single flare fitting instead of a double flare fitting.
