Severe gas smell left in a closed area after corvette use. When the car is driven and then parked in a garage, the garage smells severely of fuel. If aired out, the smell dissipates. If not, the odor is overwhelming. Upon review, it appears the smell is coming front the drivers side left-hand fuel tank. The leak affects the safety of the car passengers as the gasoline leak from the tank drips onto the exhaust. My mother is 94 years old and has ridden with me while this issue was occurring. Little did I understand the potential impacts on my families well-being. I believe this is a major safety hazard with this car. Upon cursory review of online corvette chat groups, this seems to specifically affect this model corvette. After further research, this problem seems to be prevalent in past corvette models extending back to 1997. Upon contacting gm/chevrolet service department we were told that our specific VIN number does not qualify for a recall. It's my understanding there is an extension of the warranty on this specific issue due to its prevalence. I also understand that the extension included mileage to 80,000 miles and through august 17, 2017. My mileage currently sits at 49,000 miles and we supposedly missed the deadline by 11 days as we reported this issue to the dealership on august 28, 2017. While we did purchase the car used, we never were told of the issue nor received paperwork to that affect so we were completely unaware of such a hazard. I strictly use dealerships for my service and am disappointed that they were not able to identify this issue in my opinion, it doesn't appear that the company is not interested in addressing my problem.

Fuel smell coming from the left side of the vehicle. Only happens when fueled above 3/4 of a tank. Chevrolet dealer was concerned about the problem during an oil change and tried to get gm to correct the issue but they would not citing that the vehicle passed all fuel pressure an leak tests. The vehicle is dangerous to park in a garage or closed area due to the very good chance of ignition from strong fumes. Just as disturbing is the fact that the exhaust system is by the source of the leak and could ignite at any time while driving. Many other customers have complained of this issue without a resolution from the manufacturer or if gm has agreed to replace the defective part (fuel pump) they do so with the same type that has already failed. Eventually one of these cars is going to explode or catch fire an I guess that only then will the manufacturer and the government do something about it. I have attached the service report where the dealership acknowledged the smell and the notice from chevrolet. Something needs to be done about this before there are injuries or deaths because of this.

Car has 20,000 miles and has developed a gas smell while parked in a garage. It seems to be from the right rear of the car. When the system is below 1/2 full the smell is less apparent.. There is no visible leak in the fuel tank area. I have replaced the cross over pipe seals and fuel pump "o" rings. Problem is still present. Was not aware of history of possible defective plastic on the fuel pump fittings. I will run tank below 1/2 to see if smell goes away. Will most likely remove again or address with my extended warranty as with more research this seems to be a quite common problem and potentially serious. I must let car sit outside for awhile and allow fuel fumes to diminish before I feel comfortable putting car in garage. This smell can be very heavy when left in a closed area right after driving. I can still smell fuel fumes while driving.

After filling car with gas, the car smells like it has a leak. The garage smells so bad I have to put the car outside in the drive way until is cools down because I'm worried about it starting a fire. The smell of gas is strong. I've talked to other 2008 c6 owners and they are having the same issue.
