Car smells of fuel while sitting with the engine off. From doing research it is a common problem where there is a crack in the top of the fuel pump.

With fuel at 3/4 or full, after going over pot holes or speed bumps etc. I get a raw gas smell that engufs the whole inside of the car, and lasts 5 to ten mins. This has been going on for about the last 6 months. Just came off 6500 mile road trip. Happened about eevery other day.

Constant gasoline smell in the garage when parked especially when the tank is nearly full. Just recently purchased the car and never had a problem like this before. Must leave the garage door open or leave the car outside.

Gas vapors rise from the rear wheels following a fill up. Does not happen if you only fill it half way. Fumes are really bad when vehicle is in the garage. Nothing dripped on the ground.

After driving my car for a sufficient length of time to get the engine hot (normal driving) and then park it in the garage, a very strong smell of fuel vapor is emitted from the rear area of the car which fills the garage and permeates the house. The odor also invades the car's interior cabin. This dangerous condition was reported to the watson Chevrolet dealership in tucson, August, 2015, mileage 67289. After lengthy inspection and communication with GM, certain components were replaced - an expensive repair. The car operated satisfactorily and I observed no more fuel vapors until March 4, 2016, mileage 71448. Following a trip of 40 miles, normal city driving, I parked the car in the garage and the same very strong fuel vapors filled the garage. Once again, the house was permeated with the odor, which we found necessary to purge, and to remove the car from the garage until the vapor dissipated. I consider this to be a dangerous safety hazard. I've also noted from various Corvette forums that many other C6 Corvettes have experienced this condition and it maybe a common problem. I believe cars like mine should be recalled for an appropriate fix before an explosion or other unfortunate event occurs. It won't be an accident!

There is a strong smell of gasoline coming from the car. It is difficult to pinpoint the source, but I believe there is a leak from the gas tank area.

The contact owns a 2006 Chevrolet Corvette. The contact noticed that the vehicle was leaking fuel from the fuel pump. The failure recurred numerous times. The vehicle was taken to a dealer where it was diagnosed that the fuel pump needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 36,000.

Bought car on a Friday 12/4/2015 fuel leak under drivers side under fuel fill door. Strong fumes as well. Took back to dealer Monday. Was told it will be this coming week before a technician can drop the rear suspension to get to the fuel tank. This is why I have only bought asian cars in the past. Lexus etc.

I am smelling a strong gasoline odor from the car as it is parked in the garage. It just started at random a few days ago. No visible signs of gas are on the pavement, but the smell is very strong. I am worried about a fire hazard since the exhaust is close by. There are a lot of complaints on the internet of this being a huge problem, but to my knowledge GM is not doing anything about if, my Corvette is 9'yrs old but only has 17,000 mile (a garage queen). This problem occurred out of the blue, my gas gauge reads about 5/8 of a tank so it did not happen after a fill up.,,please help.

On August 13, 2015, my 2006 Corvette would not shift out of reverse. The car was stuck in that reverse gear and the shift lever was not enabling the selection of another gear. The shifter mechanism on this automatic equipped vehicle was operational, but the linkage to the transmission was no longer engaged. The car was being pulled into the garage when this happened, so fortunately I was not in a busy intersection, in a parking lot, or in some other location where I, or someone else, might have been in harm's way due to a vehicle that I could no longer control. Since the car could not be put in neutral or park, I had to turn off the vehicle with it in reverse and use the parking brake to keep the car from moving. Since the shifter mechanism could still move, the switch activating the "ok to start" would have allowed the car to start when put in the park or neutral positions - while the transmission was still stuck in reverse; a real safety issue. The cause of the problem was a 50 cent bushing that attaches to the shift lever. This bushing allows the ball end connector of the shifter to engage a shifter cable that actuates the linkage to the transmission. So when that bushing breaks, you can no longer shift the car. This has happened to many, many people owning the generations of C5 (1997-2004) and C6 (2005-2013) Corvettes. You can read a sample thread with pictures here: or here (and there are many more!) the part replaced (the bushing) failed because of plastic deterioration, the pictures in the above links show the broken part and the part obtained to repair the problem. This problem needs serious attention!

Hello, I am reporting on my 2006 C6Z06 corvette that recently had the valve-to-guide clearances checked on my engine and my measurements are beyond the serviceable specifications on 8 out of 16 valves, both intake and exhaust. I consider this a safety hazard due to the fact that if the vehicle is driven and engine seizes, loss of control may occur. I also have what appears to be a leak on the fuel module/sending unit, specifically on the top plastic elbow connector. I have strong gasoline odor in the cabin of the car and visible gasoline from the underside of the car near the fuel tank.
