2009 Chevrolet Corvette fuel system problems

Filed Jun 3, 2026 · Fuel system · NC

When the gas tanks are more than 1/2 full the inside of the car fills with gas fumes the only way to prevent is to keep the Tanks less than half full…… worried the fumes will ignite under the right conditions…….. supposedly this is a well documented problem with the C-6 corvettes

Approximately 2 months ago I noticed a faint gasoline odor when I entered our garage. I thought that it might be due to a recent re-call on my Honda Gold Wing which involved the fuel system. The motorcycle was repaired by the dealer, returned and I never rode it until yesterday. The smell went away. I filled the Corvette, probably 3 weeks ago and the odor returned. We parked my wife's Mazda outside but the odor continued with the Corvette inside, in its normal space. I checked the floor under each vehicle, diligently, and thankfully no liquid fuel was apparent. Parking the Corvette outside, the odor went away and perhaps the same day, when leaving an evening event, I placed some folding chairs in the "trunk" of the Corvette and noticed the odor. The following day, I went to the Chevrolet dealer I normally have repair work done to make arrangements to bring it in for inspection and did so on September 8th. A few days later, I was advised that there was a leak at the top of the left tank and that the tank would have to be removed and re-sealed at the top where there is an entry area for a part involved with the fuel system. The dealer advised that they thought there was a re-call for this matter but found that either there wasn't one or it expired. I forget which. My search on GM's website for recalls as well as yours, doesn't indicate that there was one BUT this is really a serious matter and the fix is expensive. I bought the vehicle from the original owner, who is a retired GM engineer for their manufacturing plants. It has not been in an accident.

Fuel leak issue. I have a fuel leak coming from a faulty fuel pump on the driver'side. Very dangerous. Leaking down on side of tank. Could possibly leak down onto exhaust.GM said there was nothing they could do. I have taken it to Landers Mclarty Chevrolet in Huntsville, AL for replacement. Cost is $1963.02. There should have been a recall instead of a special advisory since they admitted it was a faulty plastic that causes the problem.

warning light came on checked code p0442 came up stating a small vapor leak in fuel system. replaced fuel cap , smoke test and found that the evap vent solenoid was leaking. Remove and replace fuel tank vent valve program module. Still smelled fuel. Took vette to a dealership had them do a multipoint inspection they pinpointed and diagnose the problem as the left side fuel tank module and all necessary gaskets and seals needed to be replace at a out of this world price. I believe this to be a safety risk.

Strong fuel smell from defective part on fuel assembly. I was told this is a $4000 fix for a part that was knowingly bad and GM did nothing about it. This is a fire hazard and could burn my house down the gas smell in my garage is overwhelming

The vehicle in question was 14 years old with 20,950 original miles on it. This safety issue was the direct result of a faulty part from the factory [leaking fuel pump flange assembly] that manifested itself in a very strong fuel smell, both in the vehicle while driving, as well as in my garage. It was caused by raw gasoline leaking out of the primary fuel pump that was cracked and leaked out of the fitting on the top of the fuel tank. [NOTE: GM had previously acknowledged the problem in a service advisory bulletin on Jan 17, 2017 #N150682 but was not subject to a recall]. I believe this problem should have resulted in a recall, not just a Service Advisory Bulletin. This vehicle could have very easily caught fire, while driving down the highway or idling in traffic; not to mention the fact that a buildup of gasoline fumes in the confined space of a garage could have caused an explosion and / or fire. Either or both situations could have resulted in loss of life to the driver, passengers or other innocent bystanders as well as the destruction of property. There were no warning messages on the Driver Information System of the car.

Special Coverage Adjustment 15682 Primary Tank Module Flange Fuel and Vapor Leaks The above Special Coverage Adjustment was issued by General Motors regarding fuel leakage problem in certain Corvette and Cadillac vehicles. General Motors established a date certain for the vapor and/or fuel leakage involving a failing plastic located on the left side top of the fuel cell. Unfortunately, the condition of the platic part failing is not predicable and might not be detected within the date range GM set. My 2009 Corvette is now experiencing the issue--vapor detection which means there is a small but maybe unnoticed amount of fuel actually leaking at the top of the fuel cell. Fuel leaking in area immediately above the exhaust might well result in a fire while being driven and garaged. GM should have made repairs regardless of the Company date range. GM should make repairs regardless of when the vehicle might demonstrate a hazard situation do to a part failure.
