Prior to the beginning of this problem, the vehicle was operating normally. When the vehicle was refueled to full, a strong smell of gasoline would surround the vehicle and fuel would begin to drip from under the vehicle in the area of the fuel tank. When tank was filled only partially (below 75%) only the strong smell of gasoline would occur after refueling. The vehicle was taken to a gm dealership and an inspection was performed and a crack was found in the fuel tank where the filler neck attaches to the body of the fuel tank. The fuel tank was replaced and the problem has been corrected.
