Defect investigations

Fuel Leakage From The Fuel TankOpened March 15, 2013, closed December 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

Driver Air Bag Circuit High ResistanceOpened May 14, 2010, closed November 24, 2010

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 the federal safety agency 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.

This is not about an accident. It's about the vehicle's condition. Precisely, about the brake service warning. Red warning with beeping on dashboard saying I need to bring it to workshop for service. My wife was driving this car when she felt something was wrong with the car and she brought it to her trustful mechanic for check up right away sameday That mechanic gave up to look any further suggesting a visit to MB dealer.

Car smells like gas. Constantly a couple machanic. Did some repairs. But there’s a small leak as well from a smoke test. Gas leaks in more than one area. Oil leaks everywhere. Evap leak didn’t pass smog. Then went to a smog station and repair. Check engine light back on again. I saw Mercedes had an extended warranty to avoid recalling several safety complaints. I got the car from a guy who never looked into recalls or extended warranty for these complaints. Please help me to get refunded what I payed so far with repairs on gas leaks. Also to repair the whole gas system. It is dangerously ongoing. I never got notified by Mercedes nor did the previous owner.

Several times if the vehicle is not driven in a day or two the battery would be dead.I had to replace the battery twice in 2 years. I now receive a message (check battery) every time I start the vehicle. I bought a battery charger that I keep with me all the time. Once a month I put the vehicle on a battery charger, and if I’m not going to use it for a week or more,I put it on a trickle charger. I own 2 other vehicle and none of them need this type of treatment.

I was traveling at about 60mph and started to slow to turn off the highway. Suddenly a red brake warning light came on and it took tremendous pressure to slow the car down and I overshot the turn. Then the car had no power. I was 36 miles from my home. I limped at 5-20 mph to a friends house and had the car towed to my home. There was absolutely no warning of any kind of brake problem. The car was driving just fine before this happened. I believe it could have been a much worse situation had I been in any kind of traffic.

I was sold this car and because I did not know what the red "STOP CAR TOO LOW WARNING" meant when I was driving it home, I was not only scammed by the used car dealership with no recourse, but I also was tricked into driving this car while it was not supposed to be driven for safety, per the manual of the vehicle. I will include a picture of the safety message from the manual where it states, "HIGH PRIORITY MESSAGES APPEAR IN THE MULTIFUNCTION DISPLAY IN RED COLOR". and the STOP CAR TOO LOW message states very specific safety instructions that a reasonable person could not know. I am filing this recall complaint because how the system operates. I was sold this car while the struts were faulty and had already developed a leak and because the car was currently running the AIR COMPRESSOR was able to keep up with the leak during the test drive because a slow leak will only go back down after an extended time period which I believe the dealer knew because he asked me how much I was trying to spend and all of a sudden he pulled my car out of their shop telling me they just got the car and haven't put it out yet. Please help me. When I parked the vehicle at a Golf course parking lot during the test drive I was with my uncle, I did look up mechanic shops but because the car dealership was located in Farmington, MN there was no place feasibly close enough for me to have the vehicle properly inspected. The issue is the ride of the vehicle on the air suspension was perfect so there was no way of me knowing the car was not supposed to be driven over 50 mph which you will see on the safety instructions, and the vehicle could have caused an accident because there was no way of me knowing the suspension being too low could cause the wheels to rub on the wheel well if the car is too low. I even added more radiator coolant the next day when I was driving the car and the STOP CAR TOO LOW WARNING came on again. Over $5000 in repairs that I had to do because of safety, please help me.
