What this is. Aggregated owner complaints filed with NHTSA for this vehicle's year, make and model. It describes the model, not this specific car — a clean example of a high-risk model is still possible, and a bad example of a low-risk model is too. It is not a prediction, an inspection, or a substitute for a condition report or post-sale inspection.

Method. Drivetrain share = complaints tagged Power Train, Engine or Fuel/Propulsion, divided by all complaints for that model year. Share is used rather than raw counts so high-volume models aren't penalised for being common. Because a mass safety-recall campaign (Takata airbags, headlight campaigns) can flood one category and mask a real drivetrain problem, the ratio is also computed with those categories removed, and the stronger signal is scored. Thresholds: 40% high risk, 33% caution. Under 25 complaints is insufficient data. Source: NHTSA public APIs (vPIC VIN decode, complaints, recalls).

Prototype limits. Thresholds are calibrated against eight vehicles with known outcomes — four with documented drivetrain failures, four without. That separated cleanly, but eight is a small panel and the cutoffs should be re-validated on a larger set before anyone prices a car on them. The tool reads model-level history only: it knows nothing about this car's mileage, service record or condition, and NHTSA complaint data does not reliably carry failure mileage.
