How Do the Chevrolet Suburban and KIA EV9 Generations Compare?

As of 2026, the Chevrolet Suburban is in its twelfth generation, which launched in 2021 and was last updated in 2023. This places it later in its generation cycle, where many initial issues would typically have been addressed, making it potentially more reliable. The eleventh generation, spanning from 2015 to 2020, had several facelifts, suggesting a focus on refinement and feature updates over time. In contrast, the KIA EV9 is in its first generation, having been introduced in 2024. Early in its lifecycle, the EV9 might still be addressing initial production issues, a common occurrence with new platforms. The Suburban, with its mature platform, could offer more predictable reliability compared to the newer EV9.

If you prioritize reliability and are concerned about potential repair costs, the Chevrolet Suburban might be your best choice. With a reliability score of 69/100, it has a higher reliability rating than the KIA EV9. However, keep in mind that the Suburban has a history of 27 recalls and faces issues with the engine and power train.

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 via vehicles.dev. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.
