My 2007 Mercedes-Benz E63 AMG, which has developed a fuel system defect resulting in a leak. This issue poses a significant safety risk, including the potential for fire and explosion, and is directly related to a known defect that Mercedes-Benz USA has previously acknowledged through an extended warranty campaign.Safety Risk: Fuel system leaks pose an imminent danger, including the potential for fire and explosion, to vehicle occupants and others on the road. Manufacturer Acknowledgment: The warranty extension campaign underscores Mercedes-Benz’s recognition of this defect as a manufacturing issue, Repeat Occurrence: Having experienced this defect in my previous 2005 E500 4MATIC and now my 2007 E63 AMG, it is evident this issue is systemic and not isolated.Ethical and Legal Responsibility: Safety defects do not have an expiration date. Mercedes-Benz has an obligation to address this issue regardless of warranty status.Mercedes-Benz USA recognized the severity of this defect by extending the warranty coverage to 15 years and unlimited mileage for “Covered Fuel Tank Components” in specific models, including the 2003–2009 E-Class (W211). I received a notice in 2015 outlining this warranty extension, which covered the fuel tank, fuel filter/sender, fuel pump, and all related gaskets, seals, and retention rings. Additionally, Mercedes-Benz USA formally notified the U.S. Department of Transportation's the federal safety agency, specifically the Office of Defects Investigation (ODI), of this extended warranty campaign in 2014. While the ODI concluded that the nature of the leaks "does not appear to present an unreasonable risk to motor vehicle safety," I strongly disagree. Any defect involving fuel system leaks represents a substantial safety hazard, including the potential for fire, explosion, and environmental harm.

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

VIA REGULAR MAIL AND ONLINE SUBMISSION RE: VIN # [XXX] – Mercedes Benz 2007 E 63 – We would like to bring to your attention the failure of the Fort Lauderdale Mercedes Benz dealership to properly honor the repair and replacement of parts and labor covered under a recall for Fuel Tank Components for MODEL 211 (E-Class) years 2003-2009. A copy of the Recall notice which provided for an extension of the Recall thru 01/31/2021 is attached. Also attached please find a recent repair invoice for the respective repairs which should have been repaired under this recall. Mercedes Benz undertook a “partial” repair of the parts covered under this recall and at the time of that repair failed to properly repair all of the parts related to this issue/recall. Instead, they only replaced one fuel tank/fuel pump while the extended warranty coverage was in place and left the issue to materialize/manifest in the remaining fuel pump/tank despite the fact that conditions indicated it would likely fail in the near term at the time of the partial repair. Of further concern is the fact that an active Recall for the exact same item exists and remains active for later model years. Clearly, they have not fixed the cause of failure for this vital car part and continue to place drivers/owners at considerable risk. the federal safety agency – ODI It is incredulous to me, a 25+ year dedicated Mercedes Benz customer that an experienced dealership would attempt to evade responsibility for such a significant safety recall item. When this issue exists, the smell and fumes of petroleum/gas can be easily smelled from the exterior of the car. If you were to light a cigarette – you would likely cause the car to explode. When this issue existed, the interior cabin of the car would fill with petroleum/gas fumes again placing the driver at considerable risk. Please review the attached documentation and require Mercedes Benz to acknowledge that their half-hearted repair done during the recall INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO
I filled up the gas, took a short drive home, and parked in the garage. Next day, there is a strong gasoline smell in the garage as well as inside the car. This happened whenever I filled up the gas since then.
I just purchased the vehicle used from a dealership. I drove the vehicle 2000 miles home and I parked the car in my garage. I filled the gas tank prior to parking in my garage. The next morning I entered my garage and smelled a strong odor of gasoline. I could see gas underneath my car by the rear drivers side wheel and the odor of gasoline was so strong my eyes were watering and I couldn't breath well. I opened the garage door and moved the car outside(pushed it outside to avoid an explosion). The odor of gasoline is very strong by the driver's side rear compartment. I keep the fuel tank at half full or less to minimize the gasoline vaporous smell. I bought the car in chicago and drove it home to washington state.
There is a strong smell of gasoline over 1/2 tank full, and frequent check engine lights on for an evap system leak. This is a known issue with these cars, and I am concerned to drive the vehicle with gasoline fumes coming inside the car and creating a fire hazard. Mercedes knows about this problem and needs to address it.
When I fill up the fuel tank to full, I smell a strong scent of gasoline inside the car. The fuel is leaking somewhere until I burn it down to about a 3/4 tank full.
I purchased this car late july 2012 and when I went to pick it up I noticed a slight smell of gas from the left rear of car but, didn't think much of it as it was a new to me vehicle, just thought it was freshly filled up. The next time I filled up I noticed that the car smelled both inside the car and outside the car. As a new owner of a newer mb I joined mbworld form and searched this problem with e55 and e63 and found that it is a common problem for the w211 cars. Also, it seems the solution is not as obvious as one would think. On nov 14, 20012 I took it to cal star motors in glendale ca (a mercedes dealer) for repair, they told me that the cause of the problem is the seal between the sending unit and the gas tank. They replaced this part and I drove the car home as I needed to bring in car with half a tank for repair I did not notice any issue. Next time I filled up there was no smell from inside cabin and only slight smell outside. I now have filled up several times and the problem has returned. I should say that after fill up there has never been any leaked gas present when parked as I check drive daily for any evidence of leaks in any fluid. I feel that if there is a gas leak issue with this/these cars which it appears there is based on so many issues reported that mercedes has a responsibility to solve the problem as it is a very dangerous situation to leave unresolved.
Strong fuel smell after fill up for over a year. Was brought to mercedes with no fix. Recent inspection resulted in finding a puddle of fuel under the rear seat on the fuel sending unit. Further research shows this is a ongoing problem for other e-class and has been reported to the federal safety agency, and current fixes if any has been failing and even owners having to pay out of pocket for something mercedes should be fixing under warranty due to this serious potential safety and fire issue. I have two toddlers who sit in this car everyday.
Notice a gas smell after filling up the tank. Did not really took it for anything but on the second fill smell again inside the car. Being summer I drive windows down and smell was not bad until I had the AC on. Online research prove it to be the tank. And its a known defect but mb will not fix it. More I check into the problem its an on going issue with these cars. 100k and no one will listen to your issues. I now fill 3/4 as the fix and no issues and can not sell it to someone else knowing this is a problem.
After filling the car up with gasoline, there is a strong odor of gas in the cabin to the point where the windows have to be open to drive.
