Federal law requires the manufacturer to remedy a safety recall at no cost to the owner — by repair, replacement or refund — for vehicles not more than 15 years old on the date the defect was determined.

Parts are sometimes on back-order and some remedies are interim, so a dealer may not be able to complete the work immediately. A specific vehicle’s current recall status is available through NHTSA’s VIN recall lookup.
