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)
