Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

When the car is parked and the engine is off, there is a strong and persistent fuel vapor/fuel odor coming from left rear quarter panel area of the car near the fuel filler door and left rear wheel well. Odor does not seem to be coming from the fuel filler port or fuel filler cap. Fuel filler neck hose and vapor return line behind the fuel filler port appear to be dry and connections are secure. No evidence of fuel leaking from the fuel filler neck or left fuel tank; no fuel leaking onto the ground. No previous fuel spills from refueling. Fuel vapor odor fills up the garage when parked in there for several hours.

After filling tank, there is a very strong smell of gas for over a week after filling. Seems like there is leak at the top of the tank which spills out and onto the exhaust pipes. Gas must be sitting somewhere on the chassis the smell is strong enough to fill my garage and house.

After filling up my car with gas, I noticed a strong fuel smell when it was parked in my garage. When I looked under the car, I noticed a small puddle of gas on the floor. I continued to drive the car and noticed the smell and leak went away when the fuel gauge red under half-full. I then added more gas, but did not completely fill up. The smell and leak returned. When taken to the dealership for diagnosis, they indicated a known problem with the tank fill neck and the fuel pump, but no recall issued. The vehicle has not been repaired.

Took in for service and the issue was a crack at the top of the driver side fuel module. The crack was at the base of the small L shaped tube that comes out of the top of the fuel module.

The car had approx 15000 miles on it when I began to notice a strong smell of gasoline in my garage and cabin of the vehicle. I could also see where fuel had been running down the inside of the drivers side fuel tank. The gasoline vapor was overwhelming in the cabin and garage. A search of the internet revealed a long history of leaks on the fuel module on top of the drivers side fuel tank. My dealer confirmed this and quoted me $2100 to replace the cracked fuel module. The leak drips very close to the exhaust pipe and would appear to be a serious safety issue. I strongly recommend an investigation and or recall of these cars based on the number of complaints on the internet.

Strong fuel smell coming from car when the car was turned off. Smell started on the outside of the car, but eventually (over the course of a couple days) leaked into the cabin. By this time the car also smelled of fuel when on. Left car in garage for a few hours while hiking, came back and opened the garage and started coughing from all the fuel fumes. No visible liquid leaks, but the smell was very strong. I aired out the garage and parked the car outside and took it in the next day, was told the fuel pump cracked. This shouldn't happen after 7 years of low to moderate use. This was also during thanksgiving - if I had gone away for the holiday, the spark from my gas hot water heater may have caused an explosion while I was away. The amount of fuel vapor in my garage was enough to cause difficulty breathing. Also, while driving to the dealership, my father (following in another vehicle) said he smelt a strong scent of fuel whenever I stopped at a light. Considering how close the left fuel tank (where the fuel pump is located) is to the hot exhaust pipe, I'm lucky the fuel didn't leak onto the pipe and start a fire with me inside. As a side note, as soon as I described the problem to my service rep at the dealer they said this has actually been a common occurrence over the past few months for the 2008 vehicles. When I talked to the rep, there is a new part on the market that GM will replace my old, cracked part with - which tells me GM knows about this problem, and yet failed to disclose this could happen.

Strong fuel odor after filling car with gas, almost unbearable in closed space (like a garage). Dealer readily noticed odor when car was taken in for service. Odor originates near fuel fill door (driver's side, rear wheel well). Dealer diagnosed fault as leaking fuel tank, possibly due to cross-over pipe connecting left and right halves of tank or fuel pump; probably high on the tank; no gas drips on garage floor, evaporates before dripping. Estimated cost to repair >$1550 not including parts. Fuel vapor leaks are dangerous. This type of problem has been described for Corvettes as early as the 1996 model year.

Started noticing an emitting of gasoline odors on the drivers side by the rear wheel well. Replaced the gas cap, odor still there noticed odor after filling gas tank. Odor remains until gas tank falls at below 1/2 tank. Advised possibly fuel cross over line between two tanks this seems to be a more typical occurrence on C5 and C6 Corvettes.

Strong smell of gasoline inside and outside of my 2008 C6 Corvette with no visible fuel leaks. The overpowering vapors leak into the house when parked in the garage making a highly dangerous flamable safety issue. The local Chevrolet service center quoted $1,400 to pull the fuel tank and replace a charcoal canister, and they indicated this was a known concern. In researching this issue on open forums, found numerous identical issues. My vehicle has only 48,000 miles. This should be a safety recall at a minimum before a vehicle catches fire or explodes in a closed space near gas water heater with Pilot light.

Strong, overbearing smell of gasoline inside and outside of the car at all times. I cannot drive it because of the fumes. I cannot park it in my garage because it fills the entire area with the smell of fuel. This is dangerous. This needs to be fixed. This is my only vehicle and I cannot drive it due to the safety risks alongside the nauseating fumes, and cannot afford to fix the problem. (Chevrolet dealer quoted me $1,600 just to look for the problem, then unknown costs to fix it) this many people complaining about the same issue are not wrong. GM needs to do a safety recall before someone gets hurt or worse.
