2011 MERCEDES-BENZ CL65

While the vehicle was parked in my garage, the gas fumes came into my home. The Gas Company was called out and found the smell coming from my Mercedes. I notice a strong smell of gas inside my Mercedes 2011 AMG-CL 65. I also notice the fuel gage decreased after a day. This could have caused a fire. I took the car to Calabasas Mercedes-Benz dealership and was told that this is common, but I see no recalls. After searching I found the 2011 Mercedes recall regarding fuel spill on E-Class, GL-Class
