Which Is Cheaper to Maintain: Audi E-Tron or Porsche Cayenne?

Independent repair cost data suggests the Porsche Cayenne incurs an annual repair cost of $1,231, with owners averaging 1.1 repair visits per year and facing a 21% chance of needing a major repair. Although specific figures for the Audi E-Tron are unavailable, it's crucial to consider these metrics when evaluating ownership costs. For cost-conscious buyers, the Cayenne's relatively high repair frequency and significant major repair risk may be concerning. Without detailed data for the E-Tron, it's challenging to make a direct comparison. However, potential Audi E-Tron owners should investigate typical electric vehicle maintenance costs, which are often lower than those for traditional gasoline-powered vehicles like the Cayenne.

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.
