DURING THE LEMON LAW FINAL REPAIR ATTEMPT, THE DEALER WROTE ON WORK ORDER THAT THEY HAD INSTALLED NEW BRAKES BECAUSE THEY FOUND "AFTER MARKET BRAKES" ON CAR. THE ONLY PLACE THE CAR HAS EVER BEEN SERVICED WAS THE DEALERSHIP WHERE WE PURCHASED IT. WE ASKED THE SERVICE ADVISOR AND ASSISTANT SERVICE MANAGER (FIRST THEY SAID THE BRAKES WERE THROWN OUT AND THEN THEY SAID THE PARTS WERE SHIPPED TO MB) AND WROTE TWO CERTIFIED LETTERS TO MERCEDES BENZ FOR THE REMOVED PARTS SO WE COULD TRACK THE SERIAL NUMBERS. WE WERE IGNORED. THE REGIONAL REPRESENTATIVE WHO INITIATED THE "BRAKE REPLACEMENT" WAS CONVENIENTLY "PROMOTED OUT OF THE AREA" JUST BEFORE THE LEMON LAW HEARING SO HE COULD NOT BE QUESTIONED. WE HAD BEEN COMPLAINING ABOUT THE BRAKES, ESPECIALLY THE STOPPING DISTANCE, FROM THE BEGINNING AND THEY KEPT SAYING NO PROBLEM FOUND. THE DEALER WOULD NOT DOCUMENT IT ON THE WORK ORDERS. *JB

2EA13003 · 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

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

Status: closed (inferred from source dates) · Air Bags; Air Bags:frontal; Electrical System; Electrical System:wiring; Electrical System:wiring:interior/under Dash
Mercedes-Benz USA (MBUSA) has reported a high number of warranty claims for air bag warning lamp illumination due to a diagnostic fault code 9103 or 9123 indicating a high resistance in the driver's frontal air bag firing circuit.MBUSA's testing and evaluation have shown that this condition is the result of a faulty connector (specifically, improper wire crimp) but that it will not prevent proper deployment of the driver's frontal air bag.The faulty connector can cause the air bag circuit resistance levels to exceed the threshold that illuminates the air bag warning lamp, but they do not exceed a higher limit at which proper deployment of the air bag may no longer occur.The agency believes that further expenditure of agency resources does not appear to be warranted at this time.The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.The agency will monitor the issue and reserves the right to take future action if warranted by the circumstances.During the investigation, ODI learned that MBUSA will initiate a warranty extension program to address the faulty connectors in subject model year 2005 and 2006 E-Class and other MBUSA model/model year vehicles.This action will extend the warranty coverage for this issue to 10 years or 100,000 miles, whichever occurs first.MBUSA will notify all affected vehicle owners of this action.A bulletin describing this program is available in the investigative file.
