FUEL SYSTEM, GASOLINE

The contact owns a 2008 Chevrolet Corvette. The contact stated that a strong fuel vapor odor was noticed inside and outside the garage where the vehicle was stored. Based on research, the contact suspected a fuel pump failure. The vehicle was taken to a dealer, where it was diagnosed with a damaged fuel pump. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 65,000.

Fuel system leak. Strong odor of gasoline fuel both around and inside the vehicle. No noticeable fuel product on the ground or underneath the vehicle. I am greatly concerned that this is a very significant fire and vehicle operator/occupant safety hazard. I have also found many other C6 generation Corvette owners online that are experiencing the same thing to their C6 Corvette.

I am a long time Corvette owner and have purchased many through the years. I recently purchased a 2008 Corvette Coupe with only 30k miles, one owner vehicle. Unbelievable to me, I have had to spend over $4,000 the past month replacing the ECM and most notably the Fuel Pump, to relieve the constant Fuel Smell, not to mention the rack and pinion steering gear needs to be replaced, with again, only 30k miles on the vehicle, and that part is discontinued. The failure of the ECM almost cost my wife and I our life when we were coming home to [XXX] from [XXX] . The car completely lost all power on the highway and we almost got railed by traffic. Not a good situation to say the least. I almost had a heart attack. So we had to have it towed and finally made it home, only to find out the next day after a nice ride, my entire garage was overwhelmed with a gas smell that evening which permeated through the whole house. I took notice that GM covered this exact situation with GM Bulletin # xxx back in 2017, so they KNEW there was a problem! My question is, how can GM not cover this NOW. Many 2008 Corvettes are still being bought and sold. I spent over $2800 for this last week! I am asking you and GM to at least cover 50% of this charge. I don't think that is too much to ask. It's much cheaper than having been sued by our family, should me wife and I have not survived that situation on the road, a case I know they would have won. We should definitely be compensated to say the least! Thanks INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My recently purchased 2008 was taken to the local chevy dealer for gas fumes in the garage. The technician reported "The smell is coming from the sending unit on the driver side. There was fuel dripping down the side of the tank and the tank was wet. So the sending unit needs to be replaced" The car has only 16,427 miles on it and has been garage kept. I believe that leaking fuel is a very serious safety issue and that the now expired special service bulletin 150682 should have been a mandatory recall.

Fuel sending unit in gas tank behind the drivers side is leaking gas making it impossible to park the car in the garage. There is a great possibility of fire due to this issue. No, I have not taken it to the dealer as of today but I am going to schedule it. No. No.

Bought this vehicle recently and filled it up with fuel and fumes overtook the cabin area and some leaked out the top of the tank down through the tank support. From the research I have done, this is a common problem that Chevy has ignored. The parts are too expensive to just replace everything with new.

FUEL/PROPULSION SYSTEM

There is a strong smell of gas in the passenger compartment and a very strong smell of gas gas on the drivers side near the rear tire. The Chevy dealer has confirmed the the gas smell is due to a know defect where the fuel pump develops cracks in the housing because of the poor quality plastic used. The dealer estimates that it will cost between $3,000 to $4,000 to repair. This is a very dangerous problem. I'm afraid with the very strong smell of gas that an electric spark might cause the car to explode or when it's stored inside cause a vehicle and structure fire. Why has the NHTSA not made GM do a recall for this defect. It is a very serious problem. Owners of any C6 corvette are sitting on a time bomb and their life is in danger. GM has already admitted that it is a design defect but has only issued a service bulletin. Do something before people die.

FUEL/PROPULSION SYSTEM

This car has suffered a known defect that causes fuel to leak out of the tank when the tank is more than 1/2 full. Unfortunately, the leak in my vehicle occurred outside the window that GM arbitrarily set up. (10 years after vehicle put in service or 120,000 miles whichever comes first. My vehicle is a 2008 with 94,000 miles and the problem occurred recently and after GM's window. Therefore, GM will not fix this leaking fuel tank and correct a potentially life-threatening issue. The problem is that this is a serious safety issue with strong fumes inside the cars cabin and strong fumes outside the vehicle with leaking fuel on the tank. The fumes and the leaking fuel are both extreme fire issues. This is a known issue and a known condition that could cause fire and loss of life. NHTSA needs to issue an immediate safety recall to have GM fix all of these leaking fuel tanks.

I just bought a 2008 Chevy Corvette convertible and parked in the garage. The next morning the garage has distinct smell of gas throughout the garage. If my heater to the house would have kicked on the house would have blown up. This is a safety issue which should be addressed by Chevy. After researching the issue, it seems to be a common issue, which should be a recall. Even after moving it outside, when I get in the car it smells of gas.

FUEL/PROPULSION SYSTEM

After refilling my car with gas and parking it in my garage, I noticed that fuel was actively LEAKING from the bottom of my car!@#! Within a few minutes, fuel was pooling under my car on the garage floor. I immediately moved it outside and ran the car for an hour to use up enough fuel so that it was no longer actively leaking. Unfortunately, there still remains an extremely strong fuel smell, even inside the car when driving. With this fuel smell there are strong vapors in my garage. I have to park the car outside all the time, otherwise my garage will be filled with gas vapors immediately (kind of like an air-fuel bomb). The dealer tells me that it will cost $3000-4000 to fix it. This is a HUGE safety issue and should be covered under a factory recall!!!!

FUEL/PROPULSION SYSTEM

Hello NHTSA, Fuel leaks from drivers side fuel tank. I see fuel tracks down side of tank, so conclude fuel is leaking from top of tank or from fuel pump. Fuel components are plastic, and now 17 years old, so they are probably cracked from age. I have strong smell of fuel in my garage, and puddle of fuel under drivers side tank. This is a safety fire hazard gas can leak down to the exhaust system. ' Searching Corvette forums - this is a known issue many years. Searching nhtsa - there are a number of complaints logged by other C6 Corvette owners with the identical issue. GM must fix or at least share to fix this issue. The defect is caused by GM making the conscious decision to swap more durable metal parts for less durable plastic parts in the fuel pump/tank assembly. Please put pressure on GM to reach out to current Corvette owners and their dealership network to get this issue corrected and at a minimum share the cost with Corvette Owners. Let's not allow this issue be one that causes injury or even death. Thank you

After refilling my car with gas, there was a strong fuel smell. As the fuel level dropped, the smell of gas went away. With this fuel smell there were strong vapors in my garage. I had to open the garage doors and let the garage air out before starting any of my vehicles I have in the garage. It got to the point I had to part the Corvette outside. I finally took it to a mechanic (Christain Brothers Automotive Huntsville Alabama), they found the fuel boost pump (driver's side) was cracked on top. I did not have the tools or capability to change the boost pump.

The other day from my garage i smelled a overtaking smell of gas coming from my 2008 Corvette with only 22,300 miles on it. I thought it was coming from my gas cap , so i replace the cap. Replacing the gas cap didn't help there was still a overwhelming gas smell coming from the left side of the car. I also notice when the gas tank drops below a 1/2 tank the smell seams to go away. I found out there are hundreds of complaints about this issue and that there was a special coverage adjustment issued covering this problem with the Primary Tank Module Flange Fuel and Vapor Leaks for a limited time and miles. I believe such a serious safety issue there should have been a recall to fix this problem by GM regardless of time and mileage. I have taken the car to Chevrolet dealer which has confirmed the problem.

Fuel pump module leaking fuel causing fuel to drip onto the exhaust pipe. Potential fire hazard to occupants and occupants of area it is parked near. Yes the dealer and repair shop have confirmed it has cracked when it should not. It has only been inspected by the repair shop due to immediate safety concern. The symptoms were a very strong fuel odor and a puddle of fuel on the ground in the beginning of November.

FUEL/PROPULSION SYSTEM

Extreme gas fumes because of faulty fuel pump assembly. When in a closed garage area fuel leaks out of plastic fuel pump top then the vehicle is half full or more. GM to this day has not changed the part design. So you have replace it the same kind of faulty part if you can even find one. They claim since no one has died they feel a recall is not needed. I just replaced mine for $3000.00 at a Chevrolet dealership. Don't mind paying once but how long will this part with the faulty design last? I can't believe they can get away with this. Someone's going to get hurt or killed by an explosion if something isn't done. Long time GM customer but this is not except able. I know the car is 16 years old but this has been a problem since day one.

I purchased this car just 10 days ago. The first night that I got it I went in the garage and smelled a lot of gas smell. Many people including myself have their gas water heater in the garage and I started to really panic. I googled the issue and it's apparent that this is a very common issue on the 2008-2013 corvettes and GM has used a faulty fuel pump module that started deteriorating over short period of time. I had a very sleepless and stressful night that night in fear of me waking up to a garage fire. I beg of you to please start a recall on this before anyone loses their life and their house

Our local Chevrolet dealer service department has found the fuel pump housing to be cracked causing fuel vapors to leak out the fuel pump/tank. These vapors have found their way into the cabin of the car effecting the air quality. This issue also has the potential for the vapors and spray in some cases to settle around hot exhaust. Chevrolet notified a number of of owners with notification letters regarding a fix for this condition, however I was never notified by any such campaign notice/letter. I'm compelled to write this grievance as I will have to pay out of pocket thousands of dollars to correct a defect the manufacturer has allowed to go on. Thank you!

I have a 2008 Chevrolet Corvette. The current mileage (as of July 1, 2023) is 26,200 miles. I have a strong odor of gas every time I fill the gas tank to above 1/2 the tank. This is a fairly common condition, as evidenced by the hundreds of NHTSA related complaints, and the Corvette forums. Two Chevrolet Dealerships told me I need a new Fuel Pump. The most recent diagnosis at a Dealership was on June 5, 2023. They want $3,500.00 to replace the fuel pump. Chevrolet realized there is a faulty part causing the fuel odor condition. Chevrolet issued a few Bulletins about it, and offered to make the repair at no cost if you met certain conditions. I’ve enclosed the Letter that was sent to me in 2016. As you can see, it’s about the odor of fuel and fuel droplets appearing below the left-hand fuel tank when the fuel gauge is above ½. The Letter contained an underlined sentence that directed me not to take the vehicle to the dealer unless I had the above-mentioned condition. Verbatim, it says: Do not take your vehicle to your Chevrolet dealer as a result of this letter unless you believe that your vehicle has the condition as described above. Being an honest person, I did not take my Corvette to the Dealer at that time because I did not detect an odor of gas at that time. Now, a few years later, I’m experiencing the described condition on my 2008 Corvette with mileage of 26, 200. If this condition surfaces around the time mileage reaches 26,000, I can only assume that my car’s mileage was too low back when the…letter to repair… was in effect My primary complaint is that Chevrolet should not have had "time constraints". The mileage limit is 120,000, but the time constraint is around 2018. I feel Chevrolet should repair this known problem at No Cost primarily due to the fact that the vehicle has less than 120,000 miles on it. I'm attaching 2 documents produced by Chevrolet. Thank you.

Fuel leaks out the top of the tanks, and will then drip down the back side onto the hot exhaust. If parked overnight in a garage, the vapor will fill the garage and could easily be triggered into an explosion and fire from a gas water heater or other ignition source.
