2011 Chevrolet Corvette: fuel leak

Filed Feb 15, 2026 · Fuel system · FL

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 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.

I purchased this 2011 corvette on December 31st, 2021. I drove it home and parked it in the garage. The next day I smelled gas but couldn’t find any leaks. Yesterday I had the car on a lift and changed the transmission filter and fluid. While I was underneath it, I noticed liquid streaks on the left fuel tank and possibly on the right tank also. Today I googled corvette C6 gas leaks and found all the information on the problems regarding plastic on fuel pumps cracking or seals failing. I am sure that my car is having the same problem. It sounds like GM sent owners letters (possibly in 2017) which stated they would extend the warranty for 20 years or 120,000 miles. Many owners stated that their cars were over the time limit or miles when they received the letter. I feel GM should recall these cars since a fuel leak has to be the most dangerous item out there. I worry that my house could burn down or it starts on fire while I drive it.

The fuel component on this vehicle is the concern. The fuel vapor is very strong inside the car and especially outside around the driver's side. When parked in the garage, the fuel smell would seep into the house. I am afraid to park it inside the garage due to strong fuel vapor coming out of the vehicle. I am afraid that the strong fuel vapor might ignite due to other power sources inside the garage. This issue is well known in the Corvette community, on Corvette Forum. I have scheduled to bring it into a Chevy dealership on 6/8/21 for an inspection and repair. There is no drivability issue with vehicle. It starts and drives fine, just the fuel smell that is overwhelming. There is no sign on fuel leaks on the floor. There is no warning lamps, nothing that would indicate a fuel system issue. The car only has less than 19k miles as of this writing.

I am a one-time owner of a 2011 corvette grand sport vehicle. I have noticed that following a filling of the gas tank to full, a significant and persistent gasoline smell appears in my garage. I eventually brought my vehicle in for service on february 3, 2021 in order to determine the cause. I was told that a gas leak was observed from the top of the tank. In addition, I was told that the expensive replacement of the gas tank could not be found. I am now very reluctant to drive the vehicle.
