2011 Chevrolet Corvette Fuel System Problems

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

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)

Fuel smell coming from car when parked. Garage smells like fuel. Chevrolet [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There is a smell of fuel when you get in the car. Looked online and seen several people having the same issue seems to happen when you have more than a half tank of gas. See small drip after sitting under car at front of drivers side rear wheel

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.

Fuel tank is leaking, strong fumes in my garage, I have to park outside, is this a recall? I've heard so many fuel leaking problems with the C6 Corvette

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.

I recently purchased a 2011 Chevy Corvette Grand Sport from a dealer in South Florida named Greico Chevrolet in Del Rey Beach. It was purchased used and as is from this dealer, but this appears to be a quite dangerous problem. I smell gasoline on the drivers side wheel well most of the time and sometimes the smell seeps through the car into the cabin. This is not from overfilling the tank (which I do not do anyway). I researched this issue and it appears to be an issue with two GM cars. See this statement and let me know if I have a claim: "GM Special coverage adjustment 15682 update July 2016 .Condition Some 2007 to 2009 model year Cadillac XLR and 2007 to 2013 model year Chevrolet Corvette vehicles may have a condition where a fuel odor is detected, fuel droplets appear below the left-hand fuel tank with fuel gauge level above 1/2, or a malfunction indicator lamp illuminates due to a leak path in the left-hand fuel pump module flange. Special Coverage Adjustment This special coverage covers the condition described above for a period of 10 years or 120,000 miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership. For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after July 25, 2016, are covered by this special coverage and must be submitted using the labor operation codes provided with this bulletin. Claims with repair orders prior to July 25, 2016, must be submitted to the Service Contract provider. Correction Dealers are to replace the left hand fuel tank fuel pump module. The repairs will be made at no charge"

Strong odor of gas fumes in driver compartment, seems to eminate from driver side. Plastic flange on top of fuel pump is cracked and spews gas to surrounding area. Smell is constant regardless of fuel level. GM has been aware of problem for years but has yet to issue recall. They did issue temporary special coverage adjustment not adequate for earlier model years where issue was systemic. Yes my car is available for inspection. This is health and safety issue which should warrant a recall. Fire hazard as well. No warning lamps appear on dash.

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.

Upon filling fuel tank and returning home and parking vehicle in garage, fuel smell and leak was confirmed on floor of garage. Vehicle was taken to a automotive center to have inspected and automotive center stated " fuel leaking when filling with fuel." Automotive center states "was able to inspect with an inspection camera and found that top of fuel tank is leaking at the fuel pump module seal to the tank. Also can see the vapor valve is wet from fuel as well. Recommend both pumps and evap valve." Concerned for safety of vehicle when driving and parked.

EVERY TIME I FUEL UP PASSED HALF , THERE IS A STRONG SCENT OF FUEL IN THE CAR THAT WON'T GO AWAY.

THE 2011 CORVETTE STARTED HAVING STRONG FUEL SMELL AFTER DRIVING

I JUST BOUGHT THIS VEHICLE AND MY GARAGE NOW STINKS OF FUEL

WHEN FUEL TANK IS FULL FUEL LEAKS FROM TANK SMELL FUMES

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.
