Post-Warranty Vehicle Failure Patterns — NHTSA Owner Complaints, MY 2005–2025

Failure patterns whose median reported mileage is past the typical 60,000-mile powertrain warranty — i.e. defects that statistically surface after coverage lapses, leaving owners to pay. Sorted by complaint volume. Contents: 4,953 post-warranty failure patterns. Method: Subset of the failure-mileage dataset where the median failure mileage exceeds 60,000 mi (the most common US powertrain term, 5yr/60k) and the cluster has ≥8 mileage-bearing complaints. "miles_past_warranty" is median minus 60,000. Complaints are unverified consumer reports. NHTSA complaints are unverified consumer reports.
