Cam Magnet Leak
2008 Mercedes SL550. The right passenger side Cam magnet is leaking. What is the recommended repair for this? Acceleration More than a year
C300 Turn signal flashes 3 times then goes out dash says check left turn signal
Every time I start the car, the lights are fine and no messages in dash. As soon as I use the left turn signal, it flashes 3 times then goes out. Dash says check left turn signal. The same thing applies to one of the two front parking lights on each headlight unit (left and right) and and the left side indicator. I can drive all day with no problem but as soon as the automatic headlights come on the parking lights and side maker come on briefly then go out and I get messages for each on dash. Replaced both headlight/turn signal units and the exact same issue persists. Turn it off and it starts all over. Maybe unrelated but when I use rear defroster radio gets static; also volume knob in center dash is inconsistant but the volume buttons on the steering wheel work fine. More than a year

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.
