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

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 National Highway Traffic Safety Administration (NHTSA), 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.

VIA REGULAR MAIL AND ONLINE SUBMISSION RE: VIN # [XXX] – Mercedes Benz 2007 E 63 Dear NHTSA – 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. NHTSA – 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

THE PROTECTIVE LACQUER FINISH HAS FAILED CAUSING WHEEL CORROSION AND RUST FROM THE INSIDE OUT STARTING AROUND THE WHEEL HUBS. THIS CORROSION IS LIKE A METAL CANCER THAT IS STARTING TO DETERIORATE THE PROPERTIES OF THE METALS AND ALLOYS. THIS IS A HIGH PERFORMANCE VEHICLE WITH HIGH PERFORMANCE WHEELS. THIS MFG DEFECT POSES SERIOUS SAFETY CONCERNS AND IS A PRODUCT LIABILITY THAT DAIMLER NORTH AMERICA CORPORATION DBA MERCEDES BENZ USA'S HAS KNOWN ABOUT BUT YET HAS DONE NOTHING. THIS DEFECT HAS AFFECTED SEVERAL OTHER MERCEDES BENZ VEHICLES OF THE AMG PERFORMANCE LINE. OTHER MODELS INCLUDE SLK 55 AND SLK 350 FROM 2000-2009. IN ADDITION TO RUST AND CORROSION FORMING FROM THE INSIDE OUT ON SOME WHEELS, THE BOLTS THAT HOLD THE WHEELS TO THE HUB ASSEMBLY TEND TO RUST AS WELL FURTHERING THIS SAFETY ISSUE. NOTE: VEHICLE IS USUALLY PARKED AND COVERED IN A CLIMATICALLY CONTROLLED GARAGE WHICH IS NOT EXPOSED TO THE USUAL ELEMENTS OF NATURE.

SEVERAL TAIL LAMPS QUIT WORKING. I HAD A WARNING ON THE CAR DISPLAY LISTING NUMEROUS LIGHTS ON THE TRUNK INOPERATIVE. THE LICENSE PLATE LAMP, 3RD BRAKE LIGHT, AND THE AUTO OPEN AND CLOSE OF THE TRUNK WERE INOPERATIVE. ALSO, THE EMERGENCY TRUNK RELEASE FUNCTION INSIDE THE TRUNK WOULD NOT LIGHT UP AND WOULD NOT OPEN THE TRUNK. I SEARCHED A MB WEB FORUM TO SEE IF ANYONE ELSE HAD THE SAME PROBLEM. THERE ARE NUMEROUS CARS FROM SEVERAL YEAR GROUPS THAT ARE HAVING THE SAME PROBLEM. I TRACED THE PROBLEM TO 1 BROKEN WIRE IN A WIRING BUNDLE ATTACHED TO THE LEFT HINGE OF THE TRUNK. IT APPEARS THAT THE DESIGN AND PLACEMENT OF THIS WIRING BUNDLE IS CAUSING THE WIRING BUNDLE TO FLEX AND OVER TIME, WITH THE OPENING AND CLOSING OF THE TRUNK, THE WIRES ARE BREAKING. SINCE I HAD REDUCED CAPABILITY IN BRAKE LIGHTS, I ACCOMPLISHED THE FIX MYSELF TO REPAIR THE BROKEN WIRE. THIS FIX ONLY LASTED SEVERAL MONTHS BEFORE THE SAME THING HAPPENED AGAIN. I HAVE NOW "FIXED" IT MYSELF 3 TIMES. I HAVE MY CAR AT THE MERCEDES BENZ DEALER CURRENTLY AND MENTIONED THE PROBLEM TO THEM. THEY ARE AWARE OF IT AND WANT TO CHARGE ME TO FIX IT. I FEEL THIS SHOULD BE A COVERED SERVICE BULLETIN SINCE IT IS HAPPENING TO NUMEROUS CARS NOW. THIS IS A DESIGN FLAW IN THE LOCATION AND PLACEMENT OF THIS WIRING BUNDLE AND COULD LEAD UNEXPECTEDLY LOSING SOME, IF NOT ALL, BRAKE LIGHTS. ALSO, IF SOMEONE GETS LOCKED IN THE TRUNK AND THE WIRE IS BROKEN, THEY HAVE NO WAY OF OPENING THE TRUNK. *TR

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. *TR

POWER TRAIN
Single throttle lift-off clunking noise from the side shaft when moving off (audible at the outboard end). The noise is heard once in each instance when changing direction of travel. Note: Sound file in attachment Cause If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to cracking of the microweld between the wheel bearing inner race and the joint housing of the side shaft. Note: The collar nut must always be replaced after being loosened. See also LI33.20-P-078406 Remedy Coat contact surface of side shaft with wheel bearing with Molykote paint. To do this, proceed as follows: 1. Remove side shafts 2. Clean contact surface A (see image file in attachment "Outer joint housing before") before coating with Molykote, using "spirit" (free of dust and grease) 3. Coat contact surface A (see image file in attachment "Outer joint housing after") with Molykote and leave to dry for "one hour" in removed condition 4. Reinstall side shafts Note: Before using the antifriction coating (Molykote), stir it or shake it thoroughly for (at least 1 minute).
VISIBILITY/WIPER
Complaint There are several types of complaint about noises or poor windshield wiper wiping performance: A: Wiper blades squeaking, chattering, shuddering B: The windshield is not wiped completely (streaking) C: During the downward movement water is pulled back onto the windshield from the A-pillar (Figure 1) D: After windshield cleaning, water keeps spraying onto the windshield for several wipe cycles (Figure 2) A1: The windshield and wiper blades are contaminated with residues from car washing facilities, identifiable by the water beading. The resulting differences in the friction values between the wiper blades and the windshield can excite the wiper blades to vibrate. Note: It is mostly wax residue from the washer system, but also water-repellent nano-particle coating for paint and/or silicone-based washer fluid, that could cause this problem. A partially dry windshield also has different friction values, which can likewise result in squeaking of the wiper blades A2: The wiper blades are worn by mechanical damage (wiper lip damaged by ice or insect debris, or deformed by long periods of disuse). A3: Incorrect angle of incidence of the wiper arms to the windshield. Because of this, the rubber lip of the wiper blade may not flip over at the reversal point. Cause B: B1: Wax/ dirt residues on the windshield B2: Wiper blades deformed or worn B3: Downforce of wiper arm not OK (Figure 3) Cause C: Water is pulled back onto the windshield by the differential pressure created as the wiper arm moves downwards. Cause D: Washer water collects in the fastening of the wiper blade and is blown onto the windshield by the airstream over several wipe cycles. Note and supporting information: Wiper blades are wear parts which, even when "not used" for long periods (kept in park position), may become permanently deformed and damaged. Further stresses on the rubber wiper blade arise due to various environmental influences which progressively change the effectiveness of the rubber wiper blade and accelerate the aging process. Due to the natural aging process and wear, the wiper blades should be replaced twice a year, preferably in Spring and Fall (see operator's manual). Remedy Remedy A: A1: Cleaning entire windshield with A 000 986 40 71. A2: Checking water's flow behavior after windshield has been cleaned (see Video 1). If, after cleaning, there are still areas with water beading, then the cleaning process must be carried out again until a rejection reaction is no longer present. • Note: On the vehicle in the video (Video 1), water still beads on the bottom left of the windshield. The windshield is still not properly clean, even though it appears to be clean. The windshield is only properly clean when there are no more areas on the windshield where water beads. A3: Replace wiper blades with genuine wiper blades. Important: Only exchange wiper blades if windshield no longer has water-repellent areas Note: Replacement of wiper blades is not covered under warranty and can be replaced at the expense of the customer. Remedy B: B1: Clean windshield with intensive cleaner A 000 986 40 71. Important: Do not clean the wiper blades otherwise the graphite coating will be damaged. B2: Replace wiper blades with genuine wiper blades • Note: Replacement of wiper blades is not covered under warranty and can be replaced at the expense of the customer. B3: Check the wiper arm for excessive resistance in the bearing. Restore mobility or replace wiper arm if necessary. Remedy C: Problem inherent in design for which there is no technical remedy. Exception: X204 up to 02/2014. In these vehicles, it is possible to install the design configuration of vehicles as of 02/2014. This includes wiper arms (styled arms) with improved behavior in this respect. It is also necessary to replace the wiper blades because the styled arms feature a Top Lock connection (previously Side Lock).

Complaint Headlamp, front fog lamp leaky or fogged. Cause Fogging of the headlamps is a natural phenomenon, which can occur under certain climatic conditions. It does not lead to any technical impairment of the headlamp. If a pressure compensation diaphragm is fitted in the housing cover, then the lamp unit is a "closed system". Remedy Headlamp: Remedy 1 Clearing fogged/condensed LED headlamps: 1. Drive vehicle into workshop (temperature higher than +18 °C/+64.4 °F) and connect the exhaust extraction. Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the hood. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing of fogged/condensed LED headlamps and LED rear lamps on electric vehicles: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4°F). 2. Connect battery backup via a charger. 3. Open the front-end flap and ensure sufficient ventilation. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing fogged/condensed halogen/xenon headlamps: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4°F). Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine. 3. Open the hood. 4. Switch off the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Note: If there is no visible reduction in condensation, check the headlamp for malfunctions. (see Remedy 2) It is not physically possible to defog the headlamps completely. Fogging does not impair the operation or the service life of the headlamp. Note: Only implement Remedy 1 for model series 463 (from model year 2018) and model series 465. Remedy 2 A defective headlamp can be identified as follows: 1. Check the headlamp for external damage and that the cover caps and the diaphragm are correctly seated. 2. Check the electrical connectors of the plugs and pins. 3. Check for leak tightness according to LI82.10-P-078307. The test can only be conducted on headlamps. 4. If the headlamp or the rear lamp has any external damage, replace the component part in accordance with the WIS instructions. Note: External damage to the headlamp/rear lamp or faulty seating of the cover caps does not present a warranty or goodwill case. Note: With headlamps, it is possible to install desiccant packs if the problem occurs repeatedly. • Open ventilation system LI82.10-P-078302 • Closed ventilation system LI82.10-P-078304

Complaint Headlamps leaking or fogged Cause The fogging of the headlamp is a natural phenomenon which can occur under certain climatic conditions. In contrast to a leaky headlamp, physical fogging does not result in a technical impairment of the headlamp. A leak test must be performed to determine if physical fogging exists or if the headlamp is leaky. Remedy In advance, observe LI82.10-P-078301 "Headlamp/front fog lamp leaky or fogged". 1. Prepare headlamp/check for external damage: For headlamps with a closed system • Check the headlamps for any external damage and check also for correct seating of the Gore-diaphragm/correct latching of the cover caps. • If the headlamp exhibits any external damage, replace the headlamp. For headlamps with an open system • Check the headlamps for any external damage and seal off the vent then make sure the cover caps are latched correctly into place. • If the headlamp exhibits any external damage, replace the headlamp. Note: A headlamp with external damage is not a warranty or goodwill case. 2. Leak test of headlamp with overpressure: Connect test adapter to pressure tester. (Figure 1) Check test adapter for leak tightness. To do so, connect plug and coupling (Figure 2) and apply a maximum overpressure of 30 mbar. • The pressure must remain constant. If the pressure does not remain constant, use a new adapter. Seal all the outlet openings using sealing compound and the given diaphragm with the plunger (Figure 3). (Figure 4) • Make allowance for the different headlamp variants here (there are different outlet openings). Check if the headlamp needs to be removed to gain access to the diagnostic socket on the headlamp housing. Plug the adapter onto the diagnostic socket on the headlamp housing. (Figure 5). Apply a maximum of 30 mbar overpressure to the headlamp housing. Note: If the maximum overpressure of 50 mbar is exceeded the headlamp seal will be damaged. • If a pressure drop of less than 10 mbar is measured within 30 seconds, the headlamp is tight and there is natural physical condensation• If a higher pressure drop than 10 mbar is measured within 30 seconds, the headlamp is leaky. Note: The leaky position can be localized with the aid of soap suds. Replace any leaky headlamps. Desiccant packs can be installed for headlamps that are not leaky. Observe the following documents for installation of desiccant packs: • LI82.10-P-078302 Fogged headlamp, desiccant pack installed - open ventilation system • LI82.10-P-078304 Fogged headlamp, desiccant pack installed - closed ventilation system
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
