Vehicle Reliability Scorecard
One row per vehicle (year + make + model) with its ProblemsByVin reliability score, total NHTSA complaints, recalls, and defect investigations, plus the single component owners complain about most. The master index across the whole tracked fleet — the flat table to join every other dataset to.

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… See the full description on the dataset page: https://huggingface.co/datasets/ProblemsByVin/failure-mileage-distribution.processed_dataset_orca-math-word-problems-200kDataset Description:
This dataset contains data that has undergone two preprocessing steps:
Removal of Instructions with Less Than 100 Tokens in Response: Instructions with less than 100 tokens in the response have been removed from the dataset. This preprocessing step helps to ensure that the dataset contains substantial and informative responses.
Data Deduplication by Grouping Using Cosine Similarity (Threshold > 0.95): Data deduplication has been performed by grouping similar instances… See the full description on the dataset page: https://huggingface.co/datasets/AryanAnuj/processed_dataset_orca-math-word-problems-200k.math_problemsembodied-and-math-problemsfire-crash-injury-index
Fire / Crash / Injury Complaint Index
Failure patterns where owners alleged a fire, crash, injury, or death in their NHTSA complaint, ranked by alleged deaths then fires. These are UNVERIFIED consumer reports filed with NHTSA, not confirmed incidents — they indicate where owners report the most severe outcomes, not adjudicated causation.

Recall-Gap Index
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.

NHTSA Defect Investigations
Every NHTSA Office of Defects Investigation (ODI) action touching a tracked vehicle — open and historical. The leading indicator of a recall: a Preliminary Evaluation (PE) can escalate to an Engineering Analysis (EA) and then a recall. Includes the recall campaign number for investigations that became recalls.

Engine-Family Complaint Density
Curated problematic engine families (documented defect patterns — class actions, NHTSA investigations, or 100+ fleet complaints), with total NHTSA complaints, recalls, and complaints normalized per model-year entry. Density lets you compare families of different production volumes.
