NHTSA vehicle complaint intelligence (agent-curated)

NHTSA vehicle complaint intelligence (monthly)

Monthly complaint-burden ranking of US-market passenger vehicles by model year, from the official keyless NHTSA ODI complaints API (universe enumerated via vPIC). Per model-year: ODI-deduped complaint counts, crash/fire/injury/death tallies folded into a documented severity model (3*crash + 5*fire + 2*injuries + 10*deaths), a top-level NHTSA component taxonomy (VISIBILITY/WIPER -> VISIBILITY) with the dominant component and its share, year-over-year complaint change vs the prior model year, and a 0-100 complaint-burden composite (50% min-max(log1p(complaints)) + 50% min-max(severity rate)) ranked with deterministic tie-breaks. Vehicles with fewer than 5 complaints are excluded (noise gate; also screens out model keys the complaints index cannot resolve, e.g. dashed F-series keys). VINs and free-text summaries are never stored. The score is a complaint burden signal, not a defect rate: complaints are self-reported and counts are not normalized by sales volume. Primary key: (model_year, make_slug, model_slug). Cadence: monthly. Caveats: complaint counts tick as new complaints are filed, so same-month re-runs may differ slightly.
