2011 Chevrolet Corvette fuel/propulsion system problems

“I bought this vehicle in XXX with about 39k miles. About a year after purchase, I began smelling gasoline in my garage after I filled the tank. I have consulted Corvette forum ([XXX]) and find this is a common problem. If I fill the tank more than halfway, it seems to occur consistently. I recognize this car has no warranty, but this seems to be both common and a serious safety concern.”

“My 2011 Grand Sport Corvette fuel system was repaired on 2/14/22 at no cost to me by special policy 15682-03. Now, 4 years later, the same problem has occurred again. I notice fuel smell in my garage with the tank nearly full after fill-up, and upon inspection, I notice evidence of fuel leaking along the side of the primary tank behind the driver's seat which is the same problem encountered before. GM tells me no additional help for repair is not forthcoming due to the age of the vehicle. My originating dealer has first quoted me $4000.00 and later quoted me $3400.00 to repair the car. I am reluctant to discard my Corvette which remains in excellent condition otherwise. I am currently filling the car 2/3 full so I can continue using and enjoying it without wasting fuel or creating a dangerous vapor condition in my garage.”

“Fuel pump feeder is known to be a major issues on these cars. These should be a safety recall with no explanation. Feeder fitting tends to crack overtime. Recently purchased and wasn’t aware of that previous recall which the previous owner didn’t handle.”

“Fuel is leaking from the top of the driver side fuel sending unit. This is a know issue on these cars and should be fixed under a recall. This is a very dangerous issue.”

“I bought a 2011 Grand Sport Corvette and if I fill the tank over half full the gas smell is unbearable. Some one needs to recall these cars. This issue is very serious. Fuel leaks out the top of the tanks, and will then drip down the back side onto the hot exhaust. If ignored this could result in a fire and possible death. If parked overnight in a garage, the vapor will fill the garage and could easily be triggered into an explosion and fire from a gas water heater or other ignition source.”

“Fuel pump elbow at top of driver side tank cracks and allows fuel to leak out of plastic piece. Many have the same issue and all we got was a very temporary fuel pump recall. Engine light is on”
