2006 Chevrolet Corvette fuel system problems

I am smelling a strong gasoline odor from the car as it is parked in the garage. It just started at random a few days ago. No visible signs of gas are on the pavement,but the smell is very strong. I am worried about a fire hazard since the exhaust is close by. There are a lot of complaints on the internet of this being a huge problem, but to my knowledge GM is not doing anything about if, my corvette is 9'yrs old but only has 17,000 mile (a garage queen).

After driving my car for a sufficient length of time to get the engine hot (normal driving) and then park it in the garage, a very strong smell of fuel vapor is emitted from the rear area of the car which fills the garage and permeates the house. The odor also invades the car's interior cabin. This dangerous condition was reported to the watson chevrolet dealership in tucson, august, 2015, mileage 67289. After lengthy inspection and communication with GM, certain components were replaced - an expensive repair.
