| # 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.** |
|
|
| ## Columns |
| | column | meaning | |
| |---|---| |
| | `year`, `make`, `model` | vehicle identity | |
| | `component_category` | NHTSA component bucket (e.g. powertrain, engine, brakes) | |
| | `complaint_count` | complaints in the cluster | |
| | `mileage_q1` / `mileage_median` / `mileage_q3` | reported failure-mileage quartiles | |
| | `mileage_sample_size` | complaints with a valid odometer reading | |
|
|
| ## Source & methodology |
| Derived from public U.S. NHTSA owner complaints and recalls. NHTSA complaints are **unverified consumer reports.** Canonical version, full methodology, and the other datasets: **https://problemsbyvin.com/data/** . Also archived with a DOI on Zenodo: https://doi.org/10.5281/zenodo.20648310 |
