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.

The other day I smelled gas in my garage. The smell is bad until the fuel level drops below 1/2 tank. I took my car to the dealer and they said they cannot find a leak. I mentioned if this is covered under the 80k mile emission warranty and they said it was not. There are many complaints about this issue and the solution is to drop the tanks because the issue may lie in the fuel pump and leaking tanks on the top. I believe this is a serious safety issue regarding leaking fuel tanks and the consumer should not pay for a faulty item being a serious safety issue. I know this was an issue on the c5 corvette and gm replaced those tanks free of charge. The c6 fuel cell is the same as the c5 and it appears like its also faulty as well. Please review all c6 corvettes (2005-2013) complaints on this site. This should be a recall or a fix by gm to cover the costs.
