Other Fuel System Hoses Lines/piping, And Fittings problems of the 2003 Mercedes Benz E320

When my windows are down and im driving you can smell gasoline very strongly in the car. Even worse in the back seat area. Especially if my gas tank is filled. Im constantly getting a warning to check the gas cap and the gas light goes off flashing then my check engine light will go on.

Gas tank leaks, car is 2 years out of coverage for gas tank. The original program did not leave much room for 2003 owners to be eligible. The tank leak at the top is an inherent design flaw that mercedes admits is a problem but washes their hands of it after the program eligibility expiration. There is a noticeable gas smell coming from the left rear wheel area and the leak can be seen coming from the top of the tank when the fuel filter access plate is removed.

We have been experiencing fumes of gas after the gas tank is completely filled. Later the car developed rough idling. We took the car to mercedes-benz of oklahoma city where the car has always been serviced for inspection, the dealership kept the car for four days. In the mean time we received a letter from mercedes-benz of USA notifying us of extension of warranty on fuel system for up to 15 years. When we asked the dealership about it we were told they know and are following the "bulletin" issued by the company. Initially we were told there was a leak on the top of the gas tank, however the car was returned to us by replacing the fuel filter under warranty. There was no paper work so we don't know what was actually diagnosed and done. The car is still idling rough, the fuel gauge is not reading correct (though the tank is full, gauge shows 1/4th empty). We will take the car back to the mercedes dealership tomorrow. Fuel leak is a serious matter, we wish the company had taken serious steps to fix it and had informed the customers of the actual problem. Hope NHTSA will look into this matter.

I begin to smell fumes after a fill up and replaced the filler cap. This did not solve the problem and the problem progressed. I was told by the dealership were I purchased the car that the fuel tank was leaking. The dealer wants $3,000. 00 to repair something that should not be happening under normal ware.
