BOUGHT A PRE-OWNED 2003 E55 FROM MERCEDES DEALER 2005. HAVE HAD CAR SERVICED REGULARLY AND EXCLUSIVELY AT DEALER EVER SINCE. HAVE SMELLED GASOLINE SMELL IN GARAGE ESPECIALLY AFTER FILLING-UP CAR. MOST RECENTLY, ON 21-APR-15 CHECK ENGINE LIGHT LIT. TOOK CAR TO DEALER. DEALER SAID GAS TANK LEAKING AND THEY WOULD FIX IT - COURTESY OF MERCEDES-BENZ - NO COST TO ME. MY CONCERN IS: IF MERCEDES KNEW ABOUT THIS DEFECT (SEE LINK TO MERCEDES LAWSUIT (BELOW)) FOR THE PAST SEVERAL YEARS AND I BROUGHT THE CAR TO THEM FOR SERVICING, REGULARLY, FOR THE LAST 10 YEARS (AND SPENT MORE THAN $10,000 IN SERVICE OVER THOSE YEARS) WHY DID THE DEALER NOT PREEMPTIVELY ALERT ME EARLIER TO THIS VERY DANGEROUS LIABILITY AND RECTIFY IT YEARS AGO?

REFERENCE THE NHTSA ACTION# PE12001 THERE IS A FUEL LEAK AT ONE OR BOTH OF THE FUEL SENDING UNITS AND AT ONE OR BOTH OF THE FUEL PUMPS LOCATED IN THE GAS TANK OF THIS CAR. WHEN FILLING THE GAS TANK TO FULL, GAS LEAKS AND PRODUCES A VERY STRONG GASOLINE SMELL INSIDE AND AROUND THE EXTERIOR OF THE CAR. I HAVE REMOVED THE REAR SEAT TO GAIN ACCESS TO THE UNITS AND I HAVE OBSERVED STANDING GASOLINE ON THE TOP SURFACE OF THE SENDING UNIT SEALS. THERE ARE ELECTRICAL CONNECTIONS INSIDE OF THESE UNITS AND THEY APPEAR TO HAVE BEEN SHORTING DUE TO THE LEAK. THIS IS POTENTIALLY A VERY HAZARDOUS, LIFE THREATENING CONDITION. *JS

THIS VEHICLE WAS PREVIOUSLY SERVICED IN 2008 FOR THE SAME ISSUE AS PART OF A RECALL CAMPAIGN BY MERCEDES-BENZ, #2008-020001. I WAS NOT THE OWNER AT THE TIME. THE IDENTICAL ISSUE IS NOW PRESENT ONCE AGAIN, VERY STRONG GASOLINE ODOR IN THE INTERIOR, AND A LESS-PRESENT ODOR AT THE EXTERIOR. THE DEFECTIVE FUEL SENDER UNITS WILL NOW BE REPLACED AT MY PERSONAL EXPENSE, HOWEVER SINCE THIS IS A REPEAT OF A PREVIOUS ISSUE WHICH HAD ALREADY WARRANTED A RECALL, I BELIEVE THIS SHOULD BE THE RESPONSIBILITY OF MERCEDES-BENZ USA. *TR

FILLED MY JUST PURCHASED 2003 E55 AMG WITH GASOLINE ON 10/30/14 AND DROVE STRAIGHT HOME. AFTER A FEW MINUTES MY BROTHER TOLD ME THE GARAGE HAD A STRONG GASOLINE SMELL. DROVE TO WORK THE NEXT MORNING AND NOTICED THE SMELL WAS EXTREMELY STRONG IN THE CAR AND LEFT WINDOWS DOWN TO VENTILATE. DROVE HOME WITH WINDOWS DOWN AND STILL NOTICED SMELL THAT SEEMED TO BE COMING FROM BACK SEAT OF CAR. ENTERED CAR AND "GASOLINE SMELL" INTO INTERNET SEARCH TO FIND THERE IS A LARGE SCALE ISSUE, INVESTIGATION, AND LAWSUIT. WHEN PICKING THE CAR UP FROM DEALER I NOTICED THE ENTIRE REAR SEAT BOTTOM WAS NOT ATTACHED. THOUGHT IT MAY HAVE BEEN DUE TO AN INSPECTION. HOWEVER, IT TURNS OUT THAT THE ACCESS PANEL FOR THE FUEL SENDING UNIT IS DIRECTLY UNDER THE SEAT. AFTER LEARNING THIS I REMOVED THE REAR SEAT TO FIND GASOLINE ON THE ACCESS PANEL. REMOVED THE PANEL TO FIND A PUDDLE OF GASOLINE ON TOP OF THE TANK AROUND THE SENDING UNIT. IMMEDIATELY CALLED THE DEALER AND THEY SAID TO PARK THE CAR AND A TOW TRUCK WOULD DELIVER IT TO THEM. THEN THE DEALER CALLED AND PROVIDED A NUMBER FOR ME TO CALL MERCEDES BENZ USA TO ARRANGE A TOW TRUCK. MERCEDES ARRANGED THE TOW TRUCK AND HAULED THE JUST PURCHASED CAR BACK TO DEALER. DEALER IS SUPPOSED TO BE CHECKING IT ON MONDAY 11/3/14 TO LET ME KNOW THE STATUS. *TR

I GOT HOME FROM THE STORE SMELT GAS THOUGHT NOTHING OF IT AT FIRST. THE NEXT DAY I WAS DRIVING MY VEHICLE WITH THE WINDOWS DOWN GOT A BIG SMELL OF FUEL, THAT GOT ME THINKING. LATER THAT DAY WHEN I GOT HOME I STARTED SMELLING AROUND MY VEHICLE. OPENED TRUNK SMELT GAS. THEN I SMELT BOTH REAR WHEEL WELLS AND SMELLED A STRONG FUEL ODOR ON THE DRIVE SIDE REAR WHEEL. FURTHER INVESTIGATION I GOT UNDER THE VEHICLE TO CHECK IT OUT. I COULD SEE FUEL RUNNING DOWN THE SIDE OF MY FUEL TANK. SO I REMOVED MY REAR SEAT AND THE CAP UNDER THE SEAT TO SEE THE FUEL SENDING UNIT FROM ABOVE. WHEN I REMOVED THAT THERE WAS A STREAM OF FUEL SHOOTING OUT OF MY SENDING UNIT. I DID SOME RESEARCH ON THIS CLAIM AND I FOUND OUT ITS A COMMON OCCURRENCE. THAT THERE WAS A PREVIOUS RECALL AND THAT DIDN'T DO THE FIX. I HAVE A PICTURE OF THE SENDING UNIT SHOOTING THE SPRAY OF FUEL BUT THERE IS NO AREA TO UPLOAD IT ON HERE. I WOULD LIKE TO KNOW WHAT IS GOING WITH THIS. THANK YOU. *TR

2EA13003 · Fuel Leakage From The Fuel Tank
Opened Mar 15, 2013 · Closed Dec 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

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

The Office of Defects Investigation (ODI) opened this investigation based on 20 consumer reports.All of the vehicles were E55 AMG models and the complainants alleged fuel leaks or a strong odor of gasoline both inside and outside of their vehicle, particularly after refueling.Some complainants alleged that the leaks may be related to a 2008 Mercedes Benz emission recall (Campaign No. 2008020001) on the fuel filter module. This recall pertained to model years 2003-2006 E and CLS AMG models only.These AMG models use a different fuel pump and fuel filter module than the non-AMG E-class, however, they share other fuel system components, including the fuel tank.Since opening the investigation ODI has received an additional 350 reports relevant to this investigation.Of those reports, 116 reports are on the E55 AMG model.The remaining 234 reports are on other E-class models (i.e., E320, E350, E500, E550 and E63) which are now included in the scope of EA13-003.The investigation has been upgraded to Engineering Analysis, EA13-003, for further study.The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the identification (ODI) numbers cited on the following page.
