The Toyota bZ4X is more reliable than the Ford Mustang Mach-E, scoring 75/100 vs 71/100.

The Toyota Bz4x edges out the Ford Mustang Mach-E in terms of reliability, with a slightly higher average reliability score of 75 compared to 71. The Bz4x also has a lower recall count of 6 over three years, versus the Mach-E's 13 over four years, and reports fewer owner complaints at 7.1 per 10,000 sold compared to 10.7. While both vehicles share common issues with the electrical system, the Mach-E's additional problems with the power train and service brakes may contribute to its lower reliability perception. Overall, the Bz4x's superior recall history and complaint rate make it a more reliable choice.

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.
