2009 Chevrolet Corvette: gas smell in the cabin

Filed Jun 3, 2026 · Fuel system · NC

When the gas tanks are more than 1/2 full the inside of the car fills with gas fumes the only way to prevent is to keep the Tanks less than half full…… worried the fumes will ignite under the right conditions…….. supposedly this is a well documented problem with the C-6 corvettes

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.

Strong fuel smell from defective part on fuel assembly. I was told this is a $4000 fix for a part that was knowingly bad and GM did nothing about it. This is a fire hazard and could burn my house down the gas smell in my garage is overwhelming

The vehicle in question was 14 years old with 20,950 original miles on it. This safety issue was the direct result of a faulty part from the factory [leaking fuel pump flange assembly] that manifested itself in a very strong fuel smell, both in the vehicle while driving, as well as in my garage. It was caused by raw gasoline leaking out of the primary fuel pump that was cracked and leaked out of the fitting on the top of the fuel tank. [NOTE: GM had previously acknowledged the problem in a service advisory bulletin on Jan 17, 2017 #N150682 but was not subject to a recall]. I believe this problem should have resulted in a recall, not just a Service Advisory Bulletin. This vehicle could have very easily caught fire, while driving down the highway or idling in traffic; not to mention the fact that a buildup of gasoline fumes in the confined space of a garage could have caused an explosion and / or fire. Either or both situations could have resulted in loss of life to the driver, passengers or other innocent bystanders as well as the destruction of property. There were no warning messages on the Driver Information System of the car.

Gas is leaking/spraying from a defective high pressure fitting on top of left side fuel tank fuel pump. My garage was full of gas fumes and a strong odor was seeping into my home. Car had to be removed from garage for fear of explosion. This is a known and very common problem with C6 Corvette fuel pumps. GM will only fix if less than 10 years old and less than 120,000 miles. Dealer first said my car would be covered and not to worry, but after disassembling and confirming this common issue, they then tell me I'm not covered and must pay out of pocket. My car is in pieces and they are waiting for a back ordered pump. My car has 45000 miles but is more than 10 years old so I must now pay $2,700. to correct a potentially deadly and well documented fuel system defect. Why is there no recall for this extremely hazardous defect?

A strong fuel odor persists around the driver's side fuel tank/fuel filler neck. This odor is stronger when the tank exceeds 5/8ths full. A Special Coverage Adjustment was issued by Chevrolet, ref #N150682, GWM #2015682 in January 2017 which extended the factory warranty to 10 years or 120,000 miles. I purchased this vehicle in July 2020 which exceeds that extended warranty. The fuel odor is a major problem as the vehicle is parked inside a closed garage and the vapors are strong enough to enter the house. Also the fuel odor is present inside the cabin as the vehicle is being driven. Chevrolet has not issued a recall on the dangerous problem and is unwilling to work with me on what will end up being an extremely expensive repair. Their best estimate is that the plastic OEM fitting on the downstream side of the fuel pump has a minor fracture causing fuel to spew out on top of the fuel tank where it eventually evaporates, leaving no evidence of fuel leaks under the car. This problem has been acknowledged by GM as the factory warranty was extended to cover repairs of a known factory issue causing the fuel leaks.

My 2009 corvette has an increasing fuel smell emanating from my corvette's driver side rear wheel well. The fuel vapor smell is so strong that can create a dangerous situation when the car is park in the garage where my gas hot water heater is located. After researching the issue, I've come across numerous reports of covette c6 owners reporting the same issue. The consensus seems to be that hairline cracks develop on the top of the fuel tanks causing fuel to leak on and down the side of the tank. Obviously this could lead to a serious fire hazard if it were to leak on to the vehicles exhaust. With the amount of c6 owners reporting this same issue and the potential for extreme fire hazard, I feel that general motors should address the issue. I am the original owner ofthe car and never been informed by general motors about a recall or a repair to correct the problem. I hope that filing this report will help getting this problem corrected.

Fuel smell after filling up gas tank. Apparently the gas pump on drivers side made of plastic has tendency to crack. Gm had previously paid for this repair but limited coverage to 10 yrs and/or 120 thousand miles. Bought new to me 2009 vette with 132k miles, delaer now wanting to charge $3300 for parts/labor. Cannot park in garage due to gas fumes, also dangerous to drive.
