Other Fuel System Tank Filling/charging problems of the 2008 Chevrolet Corvette - part 1

Fuel leaking from tank after filling with gas.

After filling up my 2008 Chevrolet Corvette the car has a distinct gas smell when walking up to it. The smell is strong but goes away while driving it and is not that strong once parked. After sitting for a few hours I come back and the scent is back. It seems to only emit this gasoline smell when the fuel tank is filled over half full. It has done this since I took ownership of the car in December 2020, and could have been going on for a while before that.

After filling tank with gasoline there is a leak. The fumes from the leak are very strong in my garage, requiring me to ventilate the area to prevent an explosion. I do not overfill. The auto-turnoff at the pump won't allow that. Apparently the leak is where the two tanks are connected.

Upon filling the fuel tank, there is a very strong odor of gasoline while parked. This odor does not dissipate quickly. The odor is present outside the vehicle and inside the vehicle as well. I fear that this will cause a fire or an inhalation issue for the occupants. I purchased this vehicle recently from the original owner. It has 49,000 miles. I cannot locate the source of the odor. The fuel cap was tested a few days ago during dmv inspection and was not defective.

Any time vehicle has over 1/2 tank of fuel I get fuel vapors filling my garage & inside the vehicle.

A few months ago, I filled my 2008 Corvette c6 with gas. I only filled it until the pump clicked off. I was already aware overfilling is not good for the car nor is it a safe practice. I drove about 25-30 miles before returning home. Everything seemed fine until the following morning when I went out to my garage. The smell of gas was overpowering. I immediately opened both doors in the garage to allow it to air out. I then checked the gas cap. The smell was coming strongly from the driver's side rear. I checked under the fuel tank and felt gas. I parked the car for a few weeks until I could get it into a gm dealership. After they checked it out, I was told that this was a common problem with the car. I asked if Chevrolet had issued any safety recalls and I was shocked that although Chevrolet is very aware of the problem, they don't think their customers safety is worth taking away from the bottom line. To reiterate, the fuel system is leaking, gm is aware of the fault, and it's felt that they should recall this. If someone hasn't been killed yet, someone will soon.

A continued heavy smell of fuel after filling the gas tank when sitting and not running.

On Sunday afternoon I filled my 2008 Corvette with gas. I only filled it until the pump clicked off. I was already aware overfilling is not good for the car nor is it a safe practice. I drove about 25-30 miles before returning home. Everything seemed fine until the following morning when I went out to my garage. The smell of gas was overpowering. I immediately opened both doors in the garage to allow it to air out. I then checked the gas cap. I checked for any leaks but couldn't find any. I called my mechanic and reluctantly drove 2 blocks to have it looked at. He spent about 2 hours looking the car over but couldn't find any leaks. He then called his contacts at the local Chevrolet dealer. He was told that this was a common problem with the car. He asked if Chevrolet had issued any safety recalls and we were both very shocked that although Chevrolet is very aware of the problem they don't think there customers safety is worth taking away from the bottom line. This repair is going to cost $2700. That's bad enough but can you imagine if I had been rear ended or t- boned after filling up ? I'm thinking there could have been an explosion resulting in serious injury or even death. To think that Chevrolet is fully aware of this problem and refuses to fix the problem is infuriating. I couldn't smell the fuel when I was driving, only after I had parked in the garage. I also could only detect a very slight odor when it was parked outside at the mechanics shop the following day. After the mechanic dropped the tank and shield you could clearly see fluid marks were the gas was leaking. At the very least Chevrolet could inform their customers. Perhaps like me they would choose to repair it,assuming they could afford it, rather than being trapped in a burning car. Customers like me rely on organizations like you to force companies like Chevrolet to do the right thing.

After filling the gas tank there is a strong gasoline odor in the car. I first started noticing this mid-year this year (2019). After several days, the odor is less. If the car sits for a time with more than 3/4 full tank, the odor is quite noticeable when you get in the car.

Strong fuel smell when filling car up. Lasts for days or until fuel tank gets below 1/2. No noticeable leak on the ground under.

Likely cause of fire.

After filling gas tank full, very strong odor of gasoline. Checked by mechanic and no visible gas leak. Odor continues while stationary or moving. When the tank is only half full the smell is not noticeable. Just began in September of 2017 and vehicle has 29,000 miles. Does someone have to be blown up or involved in a fire before gm takes responsibility for the defect in the fuel system? in researching this there have been numerous complaints and this should be recalled and fixed by gm.

Very strong fuel smell in garage, this happens after filling tank. Smell goes away after some fuel is used up. I have owned the car since August 2011. This problem started approximately two months ago. Another problem that started a while ago is that sometimes the transmission won't come out of park, the brake pedal needs to be tapped repeatedly while trying to shift out of park.

After filling tank with gas, fuel leaks out and leads to overwhelming gasoline smell within closed structure and within cabin. Problem dissipates after fuel level drops below 3/4 full.

The car reeks of fuel, particularly noticeable after parking in the garage overnight, and after filling it with gas. It can also be smelled inside the cabin while driving. The smell is emanating from the drivers side tank area. It's been widely reported this is caused by inferior plastic used in a nipple at the top of the fuel pump. The plastic cracks and allows fuel to be sprayed all over the top of the tank and on the exhaust system. Since my car has an automatic transmission, the driveline has to be removed to access the fuel pump. The cost of repair will be in the $2500 to $3000 range, just to replace the pump with a new one that will eventually fail again since gm hasn't done anything to fix the problem. Gm should step up and recall these cars before somebody's house burns down or somebody is killed. The fuel pump and bladder/gas tank were replace in 2013. It is happening again August 2016.

When filling the car with fuel above the half way mark a strong odor of gas can be smelled. Over night the smell is so strong in the garage you need to leave the door cracked open to vent the fumes. No visible leak is detected on the ground or near filler neck. After drive the car and gas is less than half a tank the ordor can not be detected.

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.

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.

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.

There is a gasoline leak somewhere on the car that is filling the garage with a very strong gasoline smell. There is no gas on the garage floor. I suspect a vapor leak at the top of the gas tank at the fuel pump/gage sender location. Car is now parked outside for fear of fire in the garage. Have an appointment with the Chevrolet dealer on Monday 5-4-15 to find leak and repair. Currently believe this could be a very serious safety problem!.
