Fuel odor in garage, as others, to the point you can't and shouldn't park in your garage. No evidence of fuel leaking anywhere. Tried new fuel cap, still had odor. Then read all the Corvette forum comments on the problem. Found out there was a special service bulletin/recall. I took it to dealer, and was told even though the car only has 78k miles, because the car was over 10 years old, it is not covered. Plenty of compelling information on the problem, yet manufacturer hasn't been standing behind their product from every post I read. The dealer I took it to, Tedd Britt, was not even able to find the leak, but did provide estimate of all the parts and labor. Their cost to fix problem? $7,300!

Excellent video on YouTube shows how to fix what is likely the issue/source, but not something Harry Homeowner/not mechanically inclined Vette owner would want to attempt.

Finally in 3rd quarter 2018, took vehicle over to a dealer that sells and services a large number of corvettes across all model years. Service advisor found a TSB with special extended warranty coverage that had been created by GM for this fuel leak issue. However at the end of the day; the technician could not find fuel leak source following the procedure outlined in extended warranty TSB.

Problem was not fixed and was getting worse. When parked in an closed garage overnight; the atmosphere would regularly trigger an alert from a calibrated industrial gas detector on loan from work the next morning.

Returned to dealer again late 4th quarter, 2018. Once again no problem found (qualified by; "according to the TSB procedures"). A more extensive evaluation to confirm the actual problem could be performed for ($ticker $hock Est.) that didn't include making repair. Definitely need 2nd & 3rd opinions from others before warranty coverage expires.

Last week I went into the garage and there was a strong gas smell. I looked under the car and around the car for signs of a leak and found nothing. Over the next couple of days it was the same after driving the car but still no signs of a leak. Yesterday I sniffed around the car and the gas smell seemed to come from the driver's side of the car around the filler cap AND near the bottom.

Today I tried looking under the car for signs of a leak and found nothing. But the smell is definitely coming from the driver's side. So there must be a rubber hose, tube or gasket leak somewhere that is slightly dripping gas. But the gas must be evaporating before it hits the ground.

I wonder how many Corvette owners have the same issue?
