While driving on 3/14/15 the car had trouble starting. I managed to reach home. Next morning on 3/15/15 I backed car out of garage - had the same problem starting car. After parking car in garage, I suddenly noticed that gasoline was leaking from under the left passenger seat to the garage floor. On 3/16/15 morning I called up Mercedes Benz roadside assistance and had the car towed to dealership. I was told the fuel line from the fuel filter to the engine compartment had come partially off the fuel filter. It was reconnected but I was told it could come off. This is a car my spouse drives and I am concerned about a potential fire hazard. I have drive various automobiles since I first came to the usa in December 1974 and have never had a problem like this. What should I be doing?
