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)

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.

Smelling gas fumes when parked. There were no other indicators of an issue. I took car to dealership, turns out there is a flaw with the fuel system, causing a leak at the top of the tank. Fuel was leaking through a valve and into the inside of the car frame. This issue should be a recall. The dealer would not let me leave with the vehicle due to the severity of the leak/fumes and fear of combustion! This was addressed as TSB Special Coverage Adjustment 15682 Primary Tank Module Flange Fuel and Vapor Leaks. However, my car was out of warranty/out of the range of the TSB, and I had to pay full price for the repair ($3,000 USD). This is a well documented issue on multiple corvette forums including this one: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Purchased my 2012 Corvette Grand Sport used on 06/08/2023 and the first night parked in my garage noticed a seriously strong fuel smell. Have run down to half tank and parked it again and still have the strong smell. Dropped off at my local Chevrolet dealer for inspection. Research shows this is a common issue with this model year. Chevrolet has issued service bulletin15682 for this apparent issue. Mileage is only 66k but the bulletin has a year cap of 10 years from in service date. I am searching for information as to if this has been revised and if my vehicle is still covered.

The contact owns a 2012 Chevrolet Corvette. The contact stated that while the vehicle was parked inside the garage there was an abnormally strong gasoline odor coming from the vehicle. Upon inspection, there was no fuel leak visible inside the garage. The cause of the failure was not yet determined. The manufacturer was notified of the failure and the contact was informed of a Manufacturer’s Service Campaign that addressed the failed primary fuel tank flange leak, but the Extended Warranty coverage had expired. The failure mileage was 36,000.

We smelled gasoline from time to time since June of 2022 & could not see any leaks. Approximately October 22 2022 we contacted Premier Chevy Buick GMC in Beatrice Nebraska because the smell was really bad. After they inspected our car they said it had a defective fuel pump that had cracked & it was a known common problem with the Corvettes. They advised that General Motors would repair them at no cost because of a 10 year extended coverage. They then called us the next day to tell us that it would not be covered because it missed the coverage date by 2 months. We contacted Chevrolet and we were told that it could possibly be covered under good will. They sent the dealer paperwork & have been in contact a few times. Today we received a call from Chevrolet advising we would not be paid for the repair. This should have been a safety recall because of the danger! We were never told about the possibility of the fuel pumps cracking. When we picked up the car the dealer advised it would also require a wheel alignment too because the rear suspension had been removed to do the repair.
