Fuel Loss from Filler Neck

NHTSA's Office of Defects Investigation (ODI) has received two complaints and verified a third allegation in a public forum alleging fuel loss from the subject vehicle originating from the fuel fill location while in motion. The Model Year (MY) 2010 ? 2015 Ferrari 458 (subject vehicle) has two built-in systems that are designed to prevent fuel loss: the capless fuel filler and the anti-spit back valve. Damage to the capless fuel filler was noted in all three incidents. Failure of the capless fuel fill neck and/or the anti-spit back valve to seal the fuel system may allow fuel loss from the vehicle during left-turn maneuvers. Fuel loss amounts may vary based on the lateral load exerted during these maneuvers and the level of fuel in the system.ODI is opening this preliminary investigation to characterize the scope, severity, and circumstances of the reported conditions and to fully assess their safety impact.
