10 Other Fuel System Tank Assembly problem

Failure Date: 03/06/2013

I have noticed strong gasoline odors emanating from my car after refueling. I do not 'top off' when refueling. Researched issue online at benzworld. Org and discovered that the gas odor issue I am experiencing may be related to a problem being seen in numerous Mercedes Benz e-model vehicles. This presents a very unsafe situation and I am no longer willing to park the vehicle in my garage due to the potential fire hazard. The pooling of raw gasoline also represents an environmental issue due to the evaporation and creation of toxic fumes. I understand that Mercedes Benz dealers are demanding $2,000. Or more to rectify the problem by removing and replacing the gas tanks in impacted vehicles. I feel that the manufacturer of this defective component should be held responsible to recall it and replace it. I understand that the NHTSA's current investigation action no. For this issue is pe 12001.
