How to read this
Raw totals depend on fleet size, age and owners' reporting behavior, as well as vehicle problems. The change column compares submitted reports, not failures per vehicle; it does not control for those differences. Top area is NHTSA's own component category most often cited, which can guide a pre-purchase inspection. Look up any car in the Car Complaint Checker, or read the 2026 study for the market-wide picture.
