Chevrolet Corvette fuel leak problems

Filed Nov 5, 2026 · Fuel system · FL

I recently refueled my 2014 Corvette and when I put the car in the garage it was leaking fuel causing a concentrated fuel vapor. I have since found that the fuel filler hose connector to the drivers tank had a crack in it. Obviously this is not a safe situation. In determining the situation I found that GM had a replacement program if this problem presents itself within 10 years or 120,000 miles. In my case it did not. Early customers that had this issue and before GM created the repair adjustment the dealers where charging $2000.00 with the fuel tank costs. Since then they have decided to Capitalize on this safety hazard by increasing the price of the tanks upwards of $2K and up to $6K for the replacement job. Additionally anyone else you might go to are telling customers they have to find a replacement tank because they cant. One more caveat of this situation is that many of these cars cannot be put outside until a new fuel tank is leveraged. Capitalizing on a safety issue unrcontionable. I went to GM's customer service center and they refused to help. So here I am, [XXX] 6 weeks into a leaking Saddle tank and the only help i'm getting is a hyped up service quote of 300% on keeping their customers safe.

If I fill my tank all the way, fuel leaks. It doesn't reach the ground but if you look underneath, you can see where the fuel has leaked. Also, the fumes are so bad it cannot be kept in the garage. There was a warranty program (Special Coverage Adjustment #17469) for this but there are a lot of other cars that did not display these symptoms and were not fixed while the warranty period was intact. Now the timeframe has passed (not mileage) and these parts that are known to be faulty and failing. The dealerships are trying to also tack on extra work/parts/costs to these repairs by telling customers to replace the fuel tank when in actuality, the problem is the fuel pump module and o-ring. Repairs have been quotes at $3500 which is ridiculous considering GM knew the parts were faulty.

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 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.

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.

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.

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!
