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

1

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.

2

Repair Costs

Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.

3

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.

4

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.

Frequently Asked Questions

What is the Auto Reliability Index?
Auto Reliability Index is a free, independent car reliability resource. It combines recall history, real owner complaints, repair cost data, and sales figures to help used car buyers compare reliability across makes, models, and model years.
How are car reliability scores calculated?
Scores are calculated using four weighted factors: complaint severity (35%), repair costs (30%), recall impact (20%), and issue diversity (15%). Complaints are weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. When data is unavailable for a factor, the remaining weights redistribute proportionally. Scores range from 0 (risky) to 100 (excellent).
What data sources are used?
We use NHTSA recall records, owner complaint filings, independent repair cost estimates, and publicly available sales figures to normalize complaint volumes. All data sources are publicly accessible and updated regularly.
Is this site affiliated with any car manufacturer?
No. Auto Reliability Index is fully independent. Manufacturers do not pay for placement, ranking adjustments, or score modifications. All scores are generated algorithmically from public datasets.
What is the most reliable used car in 2026?
The 2022 Lexus RX ranks #1 with a reliability score of 90/100. Rankings draw on recall history, owner complaints, and independent repair data across 1,312 model-year combinations.
Which car brands are most reliable?
Across all models in our database, Toyota and Honda consistently score highest for reliability. However, individual model years vary — always check the specific year you're considering. Browse all 29 makes on this site to compare.
