Vehicle Recall-Gap Index — High-Complaint Failures With No NHTSA Recall (verified 2026-07-21)

High-complaint failure patterns that have NO corresponding NHTSA recall — defects owners report in volume that regulators never forced a fix for. Every row is cross-checked against the live NHTSA recalls API, so vehicles that WERE recalled for the component (even when our local DB missed it) are excluded. Contents: 4,287 unrecalled failure patterns. Method: Candidates are (vehicle, component) clusters with no recall for that component in our DB and ≥ the complaint threshold. Each candidate vehicle is then queried against the live NHTSA recalls-by-vehicle API; any cluster whose component is in fact covered by a real NHTSA recall is REMOVED. Survivors are genuine recall gaps as of the verification date. Complaints are unverified consumer reports; absence of a recall is per NHTSA records on the verification date. Verification date: every "no recall" statement here reflects NHTSA records as of 2026-07-21. A recall issued after that date would close a gap listed in this snapshot. NHTSA complaints are unverified consumer reports. Source: U.S. NHTSA owner complaints and recalls (public record), model years 2005–2025.
