Failure Date: 10/01/2011

Fuel sending unit is leaking, there is a heavy fuel smell inside the car.

4 Gasoline Fuel System problem

Failure Date: 07/01/2011

After refueling vehicle, I noticed a strong odor of raw gasoline in the interior of the vehicle emanating from the rear seat area. In July, 2011, a mercedes dealership determined two sending units located under the rear seat were leaking, necessitating their replacement. The car was out of warranty and there was no mention of any recall or service campaign relative to the defective parts. The approximate cost to me was $2000. 00. Just last week, on April 6, 2012 the same event occurred wherein I refueled the vehicle and, again, noticed the same gas odor. This time I also noticed fuel had spilled on the pavement in the vicinity of the right rear portion of the underside of the vehicle. The vehicle was returned to the dealer that made the original repairs and I am awaiting their assessment of the problem. This recurrence happened just nine months and 6,000 miles after the previous repair. In the interim, I became aware of a 2008 recall involving a fuel leak on my model vehicle. I have asked the dealer to determine if the July, 2011 repair should have, in fact, been covered by the recall campaign. I have also since learned that numerous owners of my type vehicle have experienced similar gas leaks leading me to believe this is a widespread, frequent problem which has serious ramifications regarding personal safety and environmental protection. My complaint is that the manufacturer appears to have improperly designed a part or series of parts that either alone or in combination fail resulting in a hazardous fuel leak. Given the recurrence of the leak in my case in such a short period of time, it appears the remedial action is ineffective in solving the gas leak problem.

5 Gasoline Fuel System problem

Failure Date: 01/10/2011

Fuel sender unit leaked into the top of the pump area causing a smell of gasoline in the car. Sender unit was repaired but smell remained. Sender and pump unit were replaced and after 14 months the smell of gasoline is back along with pooling on the top of the pump area. When filling the car at the gas station there is sometimes a small puddle of gas under the rear filler area when done.
