2011 Chevrolet Corvette fuel system problems

Filed Jul 19, 2026 · Fuel system · TX

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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

My entire garage is filled with gas fumes after I filled my car up to full yesterday. I drive my car once every 2 weeks and this is filling my garage with fumes. There are no visible leaks, there is a technical service bulletin regarding a gas tank issue that expired. What component or system failed or malfunctioned, and is it available for inspection upon request? UNKNOWN, the vehicle is available for inspection. How was your safety or the safety of others put at risk? I could smell gas fumes from inside my garage door. Has the problem been reproduced or confirmed by a dealer or independent service center? It will be tomorrow. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not yet. Haven't got that far. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Appeared today, drove for 2 hours each direction yesterday after a 75% tank fill.

Same fuel smell issue as what GM kinda covered with Bulletin #[XXX] However that is a 10 year / 120,000 miles limit. I'm under the miles but over on time. Just purchased the vehicle (was told "there are no recalls" because they were allow to all it a "Special Warranty Adjustment". Of course the previous owner didn't get this addressed ... nor WOULD they if the smell started later. So ... still a fire hazard ... even the fix offered is replacing plastic parts with same plastic parts and crossing fingers. Dealers are quoting over 16 hours ALONE for a fix pushing costs to over $3000. And this can reoccur in the future when that plastic also fails. Metal fittings for fuel ... seems like a better choice costing only a few dollars more. Please do something for us chumps that bought the unfixed cars used. At least require dealer to fully inform buyers. "We didn't test for it because we would have to drop the tank with requires removal of exhaust, transmission etc" which is I'm sure more than 1/2 the labor of the fix minus parts. The easy test is fill it near full of gas, drive it, smell it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Gasoline drips out under the car after fill up. About 1/2 quart comes out and makes a puddle about 5 foot in diameter. Happens after every fill up. I turned in a NTHTSA complaint about fuel vapor smells after fill up on 9/6/2020 but heard nothing back. The problem has obviously progressed to leaking liquid gasoline on the ground.
