2009 Chevrolet Corvette fuel/propulsion system problems

“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…”

“Unknown. Gasoline fumes when parked with over a half tank of fuel. Fills my garage with the smell..purchased this in 2022 and I was unaware of this problem until I put it in my garage after filling the tank completely.”

“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”
