Defect investigations

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.

I recently bought a used 2005 mercedes e320 with 126.3k miles. At time of transaction, car had half a tank of fuel only. Couple days later, when I went to refuel, I filled up tank all the way to top, I drove home and as soon as I exited car, I could smell a very strong odor of gasoline inside car and inside left rear wheel well. I inspected the car and after lifting rear seat cushion, I opened the covers to gas tank to find there was a fuel leak at the fuel sending unit, driver's side, about 1-2 ounces of fuel. Today I purchased an updated new fuel sending unit from mb dealer and will need to get it installed. When tank is three quarter full or less, you don't smell the odor and no sign of leak is present. This appears to be a common problem among mercedes e-class. I've learned this thru my most recent online search. I'm so disappointed in mercedes benz for this poor manufacturing.

After filling up the fuel tank with gasoline, I smell an odor of gas until the tank is down to about 3/4 full.

Filed Jul 28, 2013 · Brakes · 80,150 miles · TX

While driving at approximately 50 MPH, the sbs system warning light came on along with loss of most braking ability. I managed to stop the car, turn around and return about 8 miles to my home in "limp home" mode. There was no warning whatsoever. I then call the mb dealership which sent a truck to pick up the car. The sbs hydraulic unit had failed and was replaced under extended warranty at no cost. While I am not complaining about the cost (none), the failure could have caused an accident with the loss of brake ability. I take road trips to the colorado mountains and if this had happened there, I could have suffered a fatal injury. This system is defectively engineered and should be replaced on all mercedes cars so equipped.
