Fuel Leakage From The Fuel TankOpened March 15, 2013, closed December 19, 2014

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

Car smells like gas. Constantly a couple machanic. Did some repairs. But there’s a small leak as well from a smoke test. Gas leaks in more than one area. Oil leaks everywhere. Evap leak didn’t pass smog. Then went to a smog station and repair. Check engine light back on again. I saw Mercedes had an extended warranty to avoid recalling several safety complaints. I got the car from a guy who never looked into recalls or extended warranty for these complaints. Please help me to get refunded what I payed so far with repairs on gas leaks. Also to repair the whole gas system. It is dangerously ongoing. I never got notified by Mercedes nor did the previous owner.

2005 mercedes e500 wagon has a strong fuel odor inside and outside the vehicle when the fuel tank is completely filled. This odor persists for a few days until the fuel level has gone down. This has persisted for about a year. Due to this safety issue, mb has extended the warranty on this part to repair it. Vehicle was taken to mb of plano for repair. Once the technician confirmed the fuel tank needed to be replaced, the technician followed the procedure which requires them to remove the muffler system to remove the fuel tank. The technician stated that a muffler bracket was rusted and would need to be replaced to complete the repair. The dealership notified me that this bracket is only available as a part of the complete muffler and would cost ~$600 to replace and would not be covered by the warranty. The muffler was operating properly and does not need to be replaced for any other reason. The dealership appealed the warranty and that was denied. I appealed to the mercedes executive referral team and they also denied the claim due to the age and mileage of the vehicle. If I am not willing to spend $600 to replace a perfectly good muffler, then I will have to drive a vehicle with two small children that has a live gasoline leak inside the cabin because mercedes benz will not replace the muffler bracket. I have been in contact with ralph at mercedes benz executive referral as well as the mercedes benz of plano service department.
