How Do the Mazda CX-90 and Toyota Highlander Generations Compare?

The Toyota Highlander is currently in its fourth generation (XU70), which began in 2020. This generation is mid-cycle, suggesting many early issues have likely been addressed, and it should be relatively reliable. The Highlander has a history of facelifts, including a notable refresh in 2017 during the third generation, which often helps refine and improve existing platforms. In contrast, the Mazda CX-90 is in its first generation, having debuted in 2024. Being early in its generation cycle, it might experience typical first-year issues as new models often do. However, its lack of detailed generation history means buyers should consider potential teething problems common in new designs.

Which Is Cheaper to Maintain: Mazda CX-90 or Toyota Highlander?

The Toyota Highlander presents a clear picture with an estimated annual repair cost of $489, averaging 0.3 repair visits per year, and a 13% chance of encountering a major repair. In contrast, Mazda CX-90 lacks specific data, making direct comparisons challenging. However, the Highlander's low repair frequency and moderate major repair risk suggest it is a reliable option for cost-conscious buyers. Over five years, the Highlander's repair costs could total approximately $2,445, providing a predictable expense framework. Without similar data for the CX-90, the Highlander emerges as a potentially better value for those prioritizing maintenance predictability and cost management.

Who Should Buy the Mazda CX-90 vs the Toyota Highlander?

If you prioritize reliability and low running costs, the Toyota Highlander is the better choice for you. With a high reliability score of 84/100, it offers peace of mind and fewer headaches over time. Its estimated annual repair cost is $489, and it has a repair frequency of just 0.3 times per year, making it a cost-effective option. While it has had 66 recalls, the low owner complaints rate of 5.8 per 10,000 sold suggests that most issues are resolved effectively.

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.
