What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
My service advisor looked at, and pronounced my fuel pump and gasket as being the culprits. A separate review by a subsequent advisor said the same. The smell is so strong as to be an embarrassment (at least) for what is otherwise a super car with only 65000 miles on it.
When the gas tank is filled up fuel is leaking from the top of the tank. After the car is driven and a few gallons of fuel are burned, the smell is no longer noticeable. The repair facility said the fuel sending unit and need to be replaced.
