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.

Defect investigations
Fuel Leakage From The Fuel Tank
The Office of Defects Investigation (ODI) opened this investigation on January 23, 2012 as PE12-001 based on 20 consumer reports in model year (MY) 2003-2006 E55 AMG vehicles.Based on new reports in other E-Class vehicles, ODI upgraded the investigation to Engineering Analysis (EA) 13-003 on March 15, 2013, and expanded the scope to all E-Class vehicles through MY 2008.The complainants alleged a strong odor of gasoline fuel both inside and outside of their vehicle, particularly after refilling the fuel tank.Many of the complainants noted that the odor subsided or went away after driving some distance thereby lowering the fuel level in the tank.Other owners reported they would only fill the tank to about three quarters full to avoid the odor altogether.Some complainants alleged fuel leaked from the fuel filter/sender, located on the top of the fuel tank on the driver's side, and collected on top of the tank.There were also allegations that the fuel leaks were associated with an Emissions Recall Campaign (No. 2008020001) conducted by Mercedes-Benz USA, LLC (Mercedes) in 2008 on MY 2003-2006 E-Class and CLS-Class AMG models.The issue in the recall involved small cracks in the pressurized outlet fitting of the fuel filter/sender.AMG vehicles are high performance models that operate at higher fuel pressure and use a different fuel filter/sender and fuel pump than non-AMG models.Information on Recall No. 2008020001 is available from the U.S. Environmental Protection Agency (EPA) website at www.EPA.gov.ODI's investigation found various leak sources that are unrelated to the outlet fitting cited in the EPA recall campaign.Through interviews with complainants, field inspections of complaint vehicles, and the collection and laboratory analysis of failed parts, three identifiable leak sources were found.The component parts and areas of the leaks involve the On-Board Diagnostic fuel tank pressure sensor (located on top of the fuel filter/sender), the outlet of the centrally mounted fuel tank fuel filling limiter valve, and the top of the fuel pump. These areas of leakage are located at the top of the fuel tank in unpressurized parts of the fuel system. When the tank is full, fuel can slowly weep/seep from micro-cracks in these components and may collect in cavities on top of the filter/sender, pump, or tank.Contrary to complainant's allegations that fuel entered the inside of their vehicle under the rear seat bench, neither ODI nor Mercedes found a plausible way for this to occur.The fuel tank is located outside of the passenger compartment, attached to the underside of the vehicle.The service access ports for the fuel filter/sender (driver's side) and fuel pump (passenger's side) are located under the rear seat bench, covered by a steel plate, sealed and bolted to the vehicle floor.When technicians service the fuel filter/sender, which has a regularly scheduled 60,000 mile service interval, and/or the fuel pump, the work is performed from inside the vehicle by working through the access ports.By letter dated September 4, 2014, Mercedes has notified the agency that it will extend the original warranty coverage to 15 years and unlimited mileage on Covered Fuel Tank Components in E-Class vehicles in MY 2003-2009 and CLS-Class vehicles in MY 2006-2011.The covered fuel tank components for the warranty extension include the fuel tank, fuel filter/sender, fuel pump, and all related gaskets/seals and retention rings.ODI is closing this investigation based on the manufacturer's extend warranty of the affected fuel system components and in consideration that the nature of the leaks does not appear to present an un

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)
Vehicle began shaking on the highway. It was coming from under the front hood and was shaking the steering wheel. The check engine light came on. I pulled over and had it towed to the Mercedes repair shop. They said it was related to a bad balance shaft and that it was a systemic problem with the engine in certain Mercedes e350s. I was told I needed to replace the camshaft and it would cost $6,000!!! After some research, it looks like Mercedes agreed, back in 2015, to cover only certain of these Mercedes, but there was no recall. I could have been killed if I was rear ended.
Vehicle headlight burned out while driving at night time reduced visibility. Upon inspection found the headlight wires insulation located behind the passenger's light bulb connector melted/burnt causing short circuit. Temporary fixing it with an electrical tape.
