I have my car in the auto repair shop and the mechanic tells me I need a pvc hose and a oxygen sensor and both those items are on a recall list. He asked me to call the dealer I was told by the dealer that those are recall items but not for my car. My complaint is why if this is a recall item it should be for all cars. Those are the only 2 things wrong with my car. I need help.

The fuel tank will only fill to 3/4 and the vehicle has an odor of gasoline inside and outside the vehicle when attempting to fill the tank. The vehicle was brought to Mercedes Benz for service for this issue and they state they do not know how to fix it and having spent approximately $10 for Mercedes to try and diagnose the problem they advised they don't know how to fix. I have noted a recall for fuel leak probe on Mercedes 2003-2008 E class models that has now been closed after Mercedes has agreed to fix the issue. I contacted Mercedes North America and they state the issue on my C class is not related to that recall and there is nothing they can do for me. The mileage on my vehicle is very low and this seems to be the same problem that occurred in my C-class that they refuse to fix.

I smelled strong vapors of gas inside my car and outside the area. I looked under car gas was pouring out from under fuel tank. Took it to ( towed that is) the shop find fuel tank was defective ! found hole in the tank on the tab if that makes sense. The shop called around for safety recall and Mercedes see if any other information. I am aware Mercedes has had problem in past with fuel tanks. The sop informed me if I drove this car with heat from exhaust would have caught fire., I am trying to contact Mercedes corporate head quarters with no luck. Is there anyway I can report file have recourse.this came to $3000 out of pocket ! not mention it could have had serious consequences !
