Tank Assembly problems of the 2005 Mercedes Benz E500

Strong fuel smell after filling tank. Fuel leaking and puddling on top of tank.

After filling up the vehicle and driving for a short period of time ,I parked the car in my garage . When I came back to the car the whole garage smelled like gasoline. After further inspection I did not see any gas leaking. When I get in the car the car smells like gas on the inside. So I drive it until the gas runs to like 1/4 of the tank thinking the smell goes away. The smell is still there and is unbearable. The car sits in the garage for a couple of months now and still reek of gas smell. The kids and wife will not go in there cause the smell is that bad!!!!!!!!!!!!!.

I took my car 2005 E500 for regular maintenance at the dealer and was told the ball bearings needed to be replaced in July 2011. Then after checking everything out, the dealer told me the fuel ring under the seat needs to be replaced. Cost usd 600. Also there was gasoline seeping out of car onto the driveway when car was parked. I started smelling gasoline smell in March 2012. I took the car again to the dealership in July 2012 and this time they replaced the fuel system. Cost usd 2100. There were puddles of gasoline in my garage after the service. I was told there might be gasoline smell. After the smell lingered after every fillup I took the car back to dealership. The dealership again wanted to charge me usd 3000 for the fuel leak but I told them I just fixed the fuel leak problem. This was in sept 2012. This time the dealership didn't charge me anything. I again took my car to the dealership for a check engine light that came on in sept 2013 to Mercedes Benz in grapevine, TX. I was told there is a leak in the fuel tank and the cost is usd 2115. I told the dealer about the NHTSA investigation, class action lawsuit for the fuel system on mercedes E500 vehicles and the service advisor, matt pinecrest, told me the case was settled and mercedes won. This is obviously a falsehood. This problem has now taken an emotional toll on me since I can't drive my car properly without worrying.
