THE FUEL TANK LEAKS STRONG GASOLINE VAPOR INTO THE PASSENGER COMPARTMENT AND OUTSIDE THE VEHICLE CREATING A FIRE HAZARD AND IMPERILS THE DRIVER'S ABILITY TO PROPERLY BREATHE. THE VAPORS ARE STRONGEST EVERYTIME THE FUEL TANK IS FILLED OVER HALF WAY. CURRENT REPAIRS ARE GOING TO COST $3000. THE MECHANIC SAYS THE ROOT CAUSE IS THE CALIFORNIA EMISSIONS REQUIRED COMPONENTS THAT ARE NONSTANDARD. THERE ARE NO PICTURES AS THE LEAKY FUEL TANK IS CONCEALED UNDER THE BACK SEAT, BELOW WHERE MY CHILDREN SIT.

I HAVE A 2008 MERCEDES E350 PZEV MODEL AND THE ISSUE I CAME ACROSS IS A MAJOR ONE. THESE MODELS IN PARTICULAR HAVE A BIG REPUTATION ON FAILING FUEL PUMPS, AND TO MAKE THINGS WORSE ON THE PZEV VERSIONS IT CAN NOT BE FIXED UNLESS THE WHOLE FUEL TANKED IS SWAPPED WITH A NEW ONE. THE FUEL PUMP IS LOCATED INSIDE THE GAS TANK AND ITS SEALED JUST SO THERE'S NO WAY OF FIXING THE ISSUE, ON THE OTHER HAND THE NON-PZEV MODELS HAVE A REPLACEABLE PUMP WHICH REDUCES THE WORK AND MONEY TO FIX THE ISSUE. MERCEDES HAS AN APPLIED EXTENDED FACTORY WARRANTY FOR THE MODEL W211 WHICH COVERS THIS ISSUE UNTIL 15YEARS / UNLIMITED MILES FOR NON-PZEV MODELS AND 15YEARS / 150K MILES FOR PZEV MODELS. I SEE THIS VERY WRONG BECAUSE THE PZEV MODELS ARE SUPER EXPENSIVE TO FIX AND MANY PEOPLE ARE OVER THE 150K MILE MARK. THIS TERM SHOULD HAVE BEEN APPLIED TO THE PZEV MODELS. I PURCHASED THIS VEHICLE FOR $3,200 BUT TO FIX THIS PROBLEM IT IS OVER THAN $3,500. I AM REQUESTING MERCEDES TO HELP ME ON THIS SITUATION AS THESE CARS ARE WELL KNOW TO FAIL IN THAT DEPARTMENT. AS IT STANDS THIS CAR IS UNSAFE TO DRIVE, IT RELEASES LOTS OF RAW GAS SMELL AND SOMETIMES IT WILL NOT START. I WANT MERCEDES TO TAKE FULL RESPONSIBILITY OF THIS MATTER BECAUSE THIS ISSUE COULD HAVE BEEN A COUPLE HUNDRED DOLLAR FIX IF THE DESIGN AFTER TANK WASN'T SO BAD. THERE ARE THOUSANDS OF PEOPLE COMPLAINING ABOUT THE SAME ISSUE WITH THE PZEV MODELS AND MOST OF THEM ARE OVER THE 150K MILE LIMIT WHICH IS NOT ENOUGH CONSIDERING THE AGE OF THE VEHICLES. *TR

FUEL HAS BEEN POOLING ON THE TOP OF THE FUEL PUMP NEAR SENDING, FOR MONTHS I WOULD SMELL GAS AFTER FILLING UP OR EVEN AT ABOUT 3/4 OF A TANK. ASSUMING I HAD PUT IN TOO MUCH; INSIDE FUEL FILLER COVER IT WARNS NOT TO TOP OFF TANK. SOMETHING I DIDN'T SEE UNTIL AFTER THE SMELL OF FUMES. UNDER MB'S PZEV WARRANTY IT STATES THAT IF THIS IS A PART THAT COULD BECOME DEFECTIVE AND HAS GIVEN OWNERS 15 YEARS/150,000 WHICHEVER COMES FIRST TO FILE A WARRANTY CLAIM AND HAVE IT REPAIRED OR REPLACED AT NO COST TO THE OWNER. MY VEHICLE HAS BEEN OUT COMMISSION FOR ALMOST 2 MONTHS BECAUSE THEY SIMPLY BELIEVE THAT I HAVE NOT MAINTAIN SERVICE OF MY VEHICLE, ACCORDING TO A COMMENT MADE BY ONE OF THEIR CUSTOMER SERVICE REPRESENTATIVES ( CALLS ARE RECORDED, DEBBIE WAS THE AGENT'S NAME AND CALL WAS MADE APPROXIMATELY AROUND 10:15 AM ON TUESDAY 2/19/2019. THE DIAGNOSTIC EVALUATION PERFORMED AT PARK PLACE MOTORS CO. IN ARLINGTON TX, DETERMINED THAT IT WAS MY FUEL PUMP AND NOT THE SENDING UNIT, STATED IN THEIR WARRANTY ALL FUEL SYSTEM COMPONENTS ARE INCLUDED PROVIDED THE VEHICLE IS WITHIN THE WARRANTY COVERAGE PERIOD. MY VEHICLE HAS 142,164 MILES AND IS JUST SHY OF 11 YEARS OLD. AFTER VIEWING AND RECEIVING REPORTS OF OTHER OWNERS WHO HAVE HAD SIMILAR ISSUES HAVE THEIR VEHICLES FIXED, AGAIN I BELIEVE THIS TO BE DISCRIMINATORY ON THE PART OF THE DEALERSHIP AND MBUSA AND ASK THAT CONTACT BE MADE TO EITHER OR BOTH TO CLARIFY WHY MY VEHICLE DOES NOT FALL WITHIN THE GUIDELINES OF THEIR WRITTEN WARRANTY COVERAGE.

CAR WAS BEING DRIVEN ON A BUSY CITY STREET, STOPPED FOR RED LIGHT, WHEN I WENT TO ACCELERATE I HAD TO PUMP THE PEDAL-TO BE SAFE I DECIDED TO TURN ONTO STREET AT INTERSECTION WHERE I WAS STOPPED AT LIGHT, CAR CAME TO A DEAD STOP IN MIDDLE OF STREET. THIS WAS VERY CLOSE TO THE FREEWAY ON RAMP THAT I WAS GOING TO. ANOTHER 1/2 MILE AND HAD I NOT DECIDED TO TURN OFF ON TO THE SIDE STREET THE CAR WOULD HAVE STOPPED IN THE MIDDLE OF A FREEWAY WITH PROBABLE FATALITIES. CAR HAD TO BE TOWED TO REPAIR SHOP. FUEL PUMP IS INSIDE GAS TANK IN THIS MODEL. REPAIR WAS $3373.88. MERCEDES BENZ DEALER HAS PARTS IN STOCK FOR A 2008 MODEL. THIS IS IN ITSELF IS UNUSUAL AND SEEMS LIKE THEY ARE EXPECTING MULTIPLE FAILS. THERE ARE ALSO MULTIPLE REPORTS OF SAME DOING AN ONLINE SEARCH. SHOULD BE RECALLED IN MY OPINION.I HAVE THE REPAIR RECEIPT AND ALL MY PREVIOUS RECORDS FOR MAINTENANCE ON THE CAR.

1EA13003 · Fuel Leakage From The Fuel Tank
Opened Mar 15, 2013 · Closed Dec 19, 2014
Status: closed (inferred from source dates) · Fuel System, Gasoline; Fuel System, Gasoline:delivery; Fuel System, Gasoline:delivery:fuel Pump; Fuel System, Gasoline:delivery:hoses, Lines/piping, And Fittings; Fuel System, Gasoline:storage; Fuel System, Gasoline:storage:tank Assembly
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
