30 AUG.16 TOOK MY 07 E350 WITH 29427 MILES TO THE DEALERSHIP BECAUSE THE CHECK ENGINE LIGHT CAME ON AND THE CAR WAS HARD STARTING. AFTER ARRIVING I INFORMED THE SERVICE WRITER THE CAR HAD SHUT DOWN WHILE DRIVING. WE WERE PROCEEDING THROUGH A BUSY MAJOR INTERSECTION WHEN THE CAR SHUT DOWN. LUCKILY IT STARTED SO WE COULD SAFELY EXIT THE BUSY MAJOR INTERSECTION. AFTER A DIAGNOSTIC TEST WAS RAN, I WAS INFORMED THE CRANKSHAFT HALL SENSOR WAS DEFECTIVE. ADDITIONALLY, THE ENGINE CONTROL UNIT, ENGINE WIRING HARNESS, CRANK SENSOR AND VARIOUS OTHER COMPONENTS ARE OIL SOAKED. I NOTIFIED MERCEDES BENZ TO BE TOLD THE CAR WAS OUT OF WARRANTY. MERCEDES BENZ SHOULD BE HELD ACCOUNTABLE FOR THE UNSAFE DEFECTIVE MATERIALS THEY USE. THE ABOVE ISSUES ARE A DANGER TO THE OCCUPANTS AND GENERAL PUBLIC AS WELL. THE DEFECTIVE OIL SOAKED WIRING HARNESS IS CAN CAUSE A FIRE. THE CAR SHUTS DOWN WHILE DRIVING IS DANGEROUS.

MY CAR IS HAVING A EXTREMELY STRONG GASOLINE SMELL INSIDE AND OUTSIDE OF MY CAR AFTER I FILL UP THE CAR. I HAVE NOT SEEN ANY GASOLINE LEAK ON THE GROUND. BUT THE SMELL INSIDE AND AROUND THE CAR IS GETTING WORSE AS TIME GOES BY AND NOW I AM AFRAID TO PARK THE CAR IN THE GARAGE. I STARTED NOTICING THE SMELL 8-10 MONTHS AGO AND IT HAS BEEN GETTING WORSE AFTER FILL UP. THE SMELL IS NOTICEABLE AFTER THE THE TANK IS HALF EMPTY. THIS IS A SERIOUS RISK THAT NEEDS TO BE ADDRESSED BY MERCEDES BENZ. MOSTLY I SMELL THE GAS WHEN THE CAR IS PARKED. THE REAR SEAT PASSENGERS HAVE COMPLAINED ABOUT THE STRONG SMELL WHEN THE CAR IS MOVING AS WELL.

FROM THE TIME IT WAS ONLY 1 YEAR OLD, THE CLIMATE CONTROL SYSTEM BEGAN REPEATEDLY TO FAIL. SOME OF THE REPAIRS DONE UNDER WARRANTY, BUT WE HAVE NOW SPENT OVER $3,400.00 ON NEW A/C COMPRESSORS (TWICE), THE EVAPORATOR (ALSO TWICE) AND VARIOUS AND SUNDRY LEAK DETECTIONS AND RECHARGES. FAILURES HAVE OCCURRED ON START-UP AS WELL AS AT HIGHWAY SPEEDS. I HAVE READ THROUGH THIS MODEL'S DEFECT RECORDS AND FOUND LITTLE IF ANY MENTION OF THE CLIMATE CONTROL. PERHAPS PART OF THE REASON MAY BE THAT THE A/C SYSTEM ISN'T INCLUDED AMONG THE CHOICES IN THE COMPLAINTS LIST. THEN AGAIN, THE ISSUE MAY BE UNIQUE TO MY SPECIFIC VEHICLE. IN ANY CASE, I WANTED IT ON RECORD AS A RECURRENT ISSUE. PERHAPS THE CLIMATE CONTROL, AND ITS IMPACT ON VISIBILITY AND THEREFORE SAFETY, SHOULD BE ADDED TO THE LIST OF OPTIONS.

EA13003 · 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
