Who Should Buy the Audi A5 vs the Lexus IS?

If you prioritize reliability and peace of mind, the Lexus IS might be the better choice for you. With a reliability score of 82/100 and only 0.7 owner complaints per 10,000 sold, it demonstrates a strong track record for dependability. While it has encountered 6 recalls, this is significantly fewer than the Audi A5. The top issues, such as structure and tires, are less critical than those involving the drivetrain or electronics. On the other hand, if you are drawn to the Audi A5 for its design or performance features, be aware of its higher estimated annual repair cost of $739 and a recall count of 16. The owner complaints rate is notably higher at 2.9 per 10,000 sold, with issues primarily in the electrical system and steering. This may indicate additional maintenance concerns down the road. However, if you are prepared for these potential costs and value the driving experience the A5 offers, it could still be a worthwhile investment.

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.
