Other Fuel System Problems of Chevrolet Corvette - part 1

Fuel leak(s) involving filler neck, fuel pump, fuel tank or associated parts in the fuel delivery system at rear of car. Gasoline smells is very strong, when the tank is filled (not overfilling the tank) gasoline puddles under the rear near the driver’s side rear tire. The fumes are so bad that the car cannot be stored in the garage (which is attached to my home). Smell is pervasive even sitting outside. I cannot drive the car for fear of gas landing on the exhaust pipe and starting a fire. I’m [xxx] and probably would not escape the vehicle. I just purchased the car and such a repair is not warranted. 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.

I purchased a 2012 Corvette from coast Chevrolet on 1-24-26. This car was supposed to have been inspected for safety issues prior to being listed for sale. Being that this is a reputable general motors dealership I assumed all safety issues and recalls would have been up to date. I drove the car home about 90 miles and immediately put it in my garage. After about 30 minutes of it being in there I noticed an overwhelming smell of gasoline. I began looking around the car both in the engine bay, underneath etc. I finally found the issue and cause for the smell. It was a leaking gas tank caused by the fuel pump. I did my research on it and found that this was a known widespread, common issue and that a service bulletin was put in place because of it. This is something the dealership should have made sure it was fixed prior to selling the car. I want this issue repaired by the dealership free of charge.

My 2011 grand sport Corvette fuel system was repaired on 2/14/22 at no cost to me by special policy 15682-03. Now, 4 years later, the same problem has occurred again. I notice fuel smell in my garage with the tank nearly full after fill-up, and upon inspection, I notice evidence of fuel leaking along the side of the primary tank behind the driver's seat which is the same problem encountered before. Gm tells me no additional help for repair is not forthcoming due to the age of the vehicle. My originating dealer has first quoted me $4000. 00 and later quoted me $3400. 00 to repair the car. I am reluctant to discard my Corvette which remains in excellent condition otherwise. I am currently filling the car 2/3 full so I can continue using and enjoying it without wasting fuel or creating a dangerous vapor condition in my garage.

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.

Cracked fuel pump housing causing vapors to vent out possibly causing a fire if stored extended periods of time indoors, and if crack is big enough fuel will drip down the back of the fuel tank onto the exhaust and possibly starting a vehicle fire.

Known fuel tank crack gm memo "special coverage adjustment 17469 fuel leaks at the primary fuel pump module flange", whose previous warranty extension has expired and shouldn't be! gm assumes no responsibility for notifying vehicle owners who purchased used vehicles from non-dealers, which is what I did. I never received any notices about this leak from them since 2018, when I bought the vehicle used from a non-gm dealer. I just recently discovered the leak and had it repaired for $ 5,300. 00. I had been driving a vehicle that could have exploded for over 7 years and did not know it. There must be others who are still driving these without knowing. Below is my request to gm to reconsider their 'not covered' response to my email. I suggest that a known special coverage adjustment 17469 fuel leaks at the primary fuel pump module flange of the gas tank is a life-threatening issue and should never expire! especially, since many of us bought these vehicles used, 2018 in my case, and have never received any notifications from dealers or gm about this issue. How many others are still outstanding and could blow someone up? the pictures below were taken at my watson Chevrolet dealer in tucson, az this month, which shows that the crack is exactly what was outlined in your publication 17469, that I never received. Total bill was $5,330. 89 (copy attached). I am asking gm to reimburse me for this horrible adventure, not to mention the danger that I've been in for these many years. While I should have detected this issue sooner, how was I to know? I finally gave a friend a ride who said she smelled a really bad gas odor, which led me to the dealer! now, gm says "you're too late" for us to cover our known defect? again, this is a life-threatening issue, and your warranty should never expire!.

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.

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 pump feeder is known to be a major issues on these cars. These should be a safety recall with no explanation. Feeder fitting tends to crack overtime. Recently purchased and wasn’t aware of that previous recall which the previous owner didn’t handle.

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.

Please refer to part 573 safety recall report 25v536. This report seeks to bring to the attention of the NHTSA that additional general motors, llc Chevrolet Corvette models not included in the recall report are virtually identical in design and having the identical safety issue. The issue: excess fuel spilled into the fuel filler pocket drains directly into the left-side fan equipped air intake. The air intake is equipped with a thermostatically controlled fan that remains running after engine shutdown if the engine temperature trigger threshold is met. While safety recall 25v536 limits the issue to those models equipped with a "radiator/fan combination", to exclude the "fan only" models (stingray z51 equipped in particular) from the recall due to not containing an "ignition source" is short-sighted to state the least in my opinion. Any electric motor is an ignition source as power (typically 12vdc in an automobile) is delivered through "brushes" to an armature that excites the magnetic fields between opposing magnets. The assumption that the addition of a radiator (essentially a sealed cavity have no spark potential) creates an ignition source combination is short-sighted at the least and criminally negligent at best. I am the owner of a 2025 stingray with a z51 package. After reviewing 25v536, I conducted a test on my vehicle by pouring water into the fuel filler pocket and monitored where that water went. The test results made it clear to me that to exclude the stingray is a mistake. Video test results are attached.

On August 1st, my '24 z06 unexpectedly caught fire after a short evening of driving — 7 miles to dinner, 7 miles to a store, then 2 miles to drop my wife off at the grocery store. I was heading to refuel when the fire started. The car was in sport mode, so the fans were running. Thankfully, we were able to put it out. Gm sent three inspectors, including an independent expert who noted that most fire cases he sees result in the car being reduced to a blob. On August 28, scott bell (vp of global Chevrolet) told our dealer he would expedite a replacement. We placed the order — but the following week, gm reversed course, claiming the fire was caused by "non-car material" and not their responsibility. Meanwhile, our insurance company determined the fire originated from the gas vent system. They’ll cover the damage ($9,000), but not the cause — leaving us to pay $1,000 out-of-pocket for the vent system. No safety lights were indicated while driving, or even after the fire (it still starts). The car is in the process of being repaired, so probably no longer available to inspect. I, as the insurance company, believe this is related to the recall on this car.

Approximately 2 months ago I noticed a faint gasoline odor when I entered our garage. I thought that it might be due to a recent re-call on my Honda gold wing which involved the fuel system. The motorcycle was repaired by the dealer, returned and I never rode it until yesterday. The smell went away. I filled the Corvette, probably 3 weeks ago and the odor returned. We parked my wife's Mazda outside but the odor continued with the Corvette inside, in its normal space. I checked the floor under each vehicle, diligently, and thankfully no liquid fuel was apparent. Parking the Corvette outside, the odor went away and perhaps the same day, when leaving an evening event, I placed some folding chairs in the "trunk" of the Corvette and noticed the odor. The following day, I went to the Chevrolet dealer I normally have repair work done to make arrangements to bring it in for inspection and did so on September 8th. A few days later, I was advised that there was a leak at the top of the left tank and that the tank would have to be removed and re-sealed at the top where there is an entry area for a part involved with the fuel system. The dealer advised that they thought there was a re-call for this matter but found that either there wasn't one or it expired. I forget which. My search on gm's website for recalls as well as yours, doesn't indicate that there was one but this is really a serious matter and the fix is expensive. I bought the vehicle from the original owner, who is a retired gm engineer for their manufacturing plants. It has not been in an accident.

Gas smells when tank is over half full it’s the plastic fuel system on to of tank is starting to crack and I was reading they have been recalled before but has gone off and this is danger and might cause a fire with the saddle bags across the back and only 30,700 miles on car.

Strong smell of fuel after parking the car in the garage. Inspection by the dealership confirmed the fuel pump assembly is leaking. The car was left for replacement of the fuel pump assembly due to the strong possibility of fire. This is a known issue with the c6 model of Corvette and was addressed by a gm TSB in 2011 rather than more appropriately by a recall. Of more concern to me is the fact that my car was produced in 2013 with a known defective part affecting safety. The cost of the repair is over $5000.

Fuel smell - possible fuel leak - the issue had been previously addressed with replacement of fuel subassembly in both saddle tanks. I believe that it is happening again . . .

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.

My vehicle is covered by gm special warranty 17469 which relates to cracks and fuel leaks at the primary fuel pump module flange. It caught fire while driving at a high performance driver’s education event at barber motorsports park and was denied coverage due to it having modifications. Gm case number 9-15085163081. There were no warning messages displayed at any time during the incident. Gm had the vehicle inspected by a “neutral” third party which turned out to be a retired gm service center instructor. None of the modifications on the vehicle affect the fuel pump module flange. This is in violation of the magnuson moss warranty act. The basic facts regarding the incident are as follows: the fire was a fuel fire, the vehicle had normal fuel pressure until I shut the engine off 2 minutes into the incident, the fuel line fittings are melted in the normal seated position, the fuel tank flange is cracked and fire damaged, the most significant fire damage is at the top of the driver’s side fuel tank (the location of the warrantied and currently cracked flange), the fire was not from any of the pressurized fuel lines. I have video from the vehicle of the incident prior to engine shutdown, pictures during and after the incident of all affected areas and components, and data logs of all vehicle parameters up to engine shutdown. These facts point strongly to the initial source of the fuel fire coming from the affected flange at the top of the driver’s side fuel tank. It is completely unacceptable that gm issued an extended warranty (and then denies coverage) for this known fire hazard vs issuing a recall. This is extremely unsafe and will lead to a loss of life if not corrected.

There was a strong fuel smell after the last 2 times I drove it. I took it to the shop and they tell me the evap canister was saturated and the fuel pump had small cracks in it likely seeping when the car heats up. I am having the fuel pump replaced, the evap canister and several seals/hoses in hopes it won't leak again.

After filling the tank with fuel, I was immediately aware of a strong smell of gas. I am always extremely careful not to overfill causing any fuel to escape. The heavy smell/escape of fumes is such that the car simply can’t be put in my garage. The risk of igniting and fire is a risk that is unacceptable. General motors knows about this issue as they did notify me in 2017 that my car could have this condition and that if it did, they would fix it at no charge. I didn’t have the issue at that time so didn’t take the car in. So, now that I the problem, I have taken the car to bradley Chevrolet in my town, lake havasu city, az and am told that in order to inspect the car for this issue, I will have to pay for 10 hours of labor ($2200) and only then will they see if they can find a new tank at another dealer. You see, gm no longer makes or has the tanks (according to their parts department). I have contacted their customer service department and have a case (#[xxx]). I am told that they will not participate going forward unless I spend the $2200 and then if they can’t find a new tank, they will put the car back together and send me home with it! it’s my belief that since this is a documented safety defect resulting in an apparent fire hazard that they would/should take care of it.

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!!!!.

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.

Fuel is leaking from the top of the driver side fuel sending unit. This is a know issue on these cars and should be fixed under a recall. This is a very dangerous issue.

Just bought 2008 Corvette with 46,000 miles. Very strong smell of fuel in car and in garage after fill up. This issue is definitely a safety issue.

Vehicle is leaving a strong gas order inside and around the vehicle. This issue is currently awaiting to be inspected but for the meantime, it’s parked inside a garage where it completely fills the area with said odor. This is particularly unsafe due to our water heater also being located in this section of the house. Gas smell first appeared about a month ago and had consistently releasing these vapors. I’ve seen that gm has released a service bulletin for a short period of time but hasn’t officially recalled the fuel issue (faulty fuel system).

I bought a 2011 grand sport Corvette and if I fill the tank over half full the gas smell is unbearable. Some one needs to recall these cars. This issue is very serious. Fuel leaks out the top of the tanks, and will then drip down the back side onto the hot exhaust. If ignored this could result in a fire and possible death. 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.

2017 Chevrolet Corvette fuel leak at the primary fuel pump module flange. Problem causes fuel odor and loss of fuel on garage floor. Vehicle was inspected and diagnosed by Chevrolet dealership.

My Corvette c6 model has had a longterm issue with the left fuel pump, which I was not made aware of by the local dealership servicing my vehicle or the manufacturer, general motors. I recently discovered the fuel pump issue, which results in a significant fuel leak thru the bottom left side of the vehicle. Gm and the dealership failed to notify me of this issue even though they issued a special bulletin that addresses the fuel pump issue and which advises dealerships to repair the vehicle at no cost to the owner - me. I have complained to general motors and I'm currently awaiting their response to my complaint and request for assistance with the repairs. As of 9:00 am pacific time, December 9, 2024, I've received no response from gm. My concern and reason for this report is gm's failure and the dealership's failure to notify me, and failure to issue a recall for this significant and dangerous problem with my vehicle.

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.

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.
