WHEELS (1 complaints)
WHEELS
1 complaintA few weeks ago, I abruptly noticed that my front right tyre pressure was lower than the rest. I went to a gas station and filled air in the tyre and all was good. I drove over 200 miles in 3 days and did not see any significant issues. After this, I didn't drive for about 3 days as I was working for home. Over these 3 days the tyres seemed to have lost pressure again! I got my types checked and turns out the wheel rims, which are manufactured by Mercedes have a crack in them. This has happened out of nowhere and for absolutely no reason at all. I did not hit anything or go over any potholes. As a certified engineer, I can attest to the fact that this is not normal, the wheel rims getting damaged before the tyres of the car are affected is not good design on the part of Mercedes. I have seen a lot of forums and a lot of people complaining about this issue and I firmly believe action needs to be taken against Mercedes to rectify this life threatening issue. Thank you.

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.
