How We Calculate Reliability Scores
Auto Reliability Index scores are calculated on a 0–100 scale using a weighted formula that combines multiple public data sources. Each factor is weighted based on its predictive value for real-world ownership experience.
Key Ranking Factors
Complaint Severity
NHTSA owner complaints weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. Adjusted for sales volume so high-volume models aren't unfairly penalized.
Repair Costs
Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.
Recall Impact
Number of NHTSA recalls weighted by severity. “Stop driving” and fire-risk recalls are penalized more heavily than minor software or labeling recalls.
Issue Diversity
Measures how many major vehicle systems (engine, transmission, electrical, braking, etc.) have recorded complaints. A vehicle with issues spread across many systems may indicate systemic quality issues.
Scores are grouped into four tiers:
- 80–100: Excellent— Top-tier reliability, minimal issues
- 60–79: Good— Reliable with some minor concerns
- 40–59: Mixed— Notable issues, research before buying
- 0–39: Risky— Significant problems, proceed with caution
Data is sourced from NHTSA recall records, owner complaint filings, and independent repair databases. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.
