2014 Chevrolet Corvette fuel system 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.

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!

09/30/2024 The smell is gasoline is emanating from the driver side after I put gas at a local gas station. A short while after I arrived home, the smell of gasoline was still strong. I observed a puddle of gas by the driver side door underneath the gas filler. I have not attempted to start the car until I know it is safe to move to a local dealership or mechanic. Any assistance would be greatly appreciated.

In November 2021, upon smelling gasoline in my garage I discovered fuel leaking from the left rear side of the vehicle. I brought the car to the Van Chevrolet dealer in Scottsdale, AZ who claimed that no recall or extended warranty was available for the vehicle. In October 2016, I received a notice from Chevrolet that my car could develop cracks in the fuel tank and to NOT take it to a dealer until the crack manifested itself. The notice Enclosure 16009 is already posted on the federal safety agency: The dealer advised that the notice had expired and I need to cover the repair out of pocket. This is a blatant safety issue with leaking fuel and the car is undrivable and is a danger to me and others. No warning lamps or messages appeared prior to the failure.
