US Vehicle Failure-Mileage Distribution (NHTSA Owner Complaints, MY 2005–2025)
For every U.S. vehicle + component failure pattern with enough mileage-bearing complaints, the mileage at which owners report the failure — as quartiles (25th percentile / median / 75th percentile). ~9,100 (vehicle, component-category) clusters derived from the U.S. NHTSA owner-complaint record.
Mileage is parsed from NHTSA's ODI bulk flat-file, which carries odometer readings the public JSON API omits, validated to a 1,000–400,000-mile band. Quartiles are published only for clusters with ≥8 mileage-bearing complaints. No other public source aggregates complaint mileage at this resolution.
