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.

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.
