Other Fuel System Tank Filling/charging Problems of Mercedes Benz CLS550

I started to notice a strong smell of gasoline inside and around my car. This occurred soon after filling up my gas tank. I looked around my car to see if I could detect any leaking, or puddling underneath my car but didn't notice many drips. The strength of the smell decreased as I drove and as the gas tank level decreased. The next time I filled up my gas tank the smell came back and was very strong. Anyone who rode in the car with me including my wife and our son, would comment on the smell. After doing some research I realized that many others have had this problem, and that there is even a class action suit open for this same type of defect in another year and model mercedes. I called to file a claim with mercedes USA, and they said that this is not something that they would cover the repairs on. I can't believe that mercedes USA wouldn't cover defect repairs for an issue many people have had, especially with the health and safety risks associated with gasoline leaking from the gas tank, as well as the gasoline fumes leaking into the cabin of the car. I hope there are enough people that voice their similar experience so that a government investigation can bring out the facts of this obvious defective issue. Long term effects of gasoline fume inhalation are suspect to cause cancer.

Check engine light came on. Reads p0456 evap small leak detected. After filling gas tank full or anything over 3/4 full. Strong gas fumes smell inside and outside of car. Checked top of fuel pump under rear driver's seat. Fuel was puddled on top of this unit. (I have pictures if needed) replaced fuel pump seal ring and gas cap with new parts. Problem has came back with more check engine codes and strong gas smell/fumes inside car. I believe e-class 03-06 have same safety issues, and hope my 07 Cls550 will be included in a possible recall, etc. As I believe the cars use same parts/platform. Refer NHTSA# pe12001.
