THE FRONT DRIVER SIDE DAYTIME DRIVING LIGHT WHICH IS ALSO THE TURN SIGNAL DOES NOT WORK. IT HASN'T WORKED FOR ALMOST 3 MONTHS AND CHEVY DOES NOT STOCK ANY HEADLIGHTS FOR THIS CAR. THIS HAS BEEN GOING ON FOR WAY TOO LONG AND I DON'T THINK THAT THEIR STATEMENT SEEMS ACCURATE ABOUT DRIVING WITHOUT THE LIGHT/TURN SIGNAL. EVEN THOUGH GM STATES IT OK TO DRIVE I FEEL IT'S NOT THAT SAFE AND HAVE NOT DRIVEN IT MUCH THESE PAST 3 MONTHS. THIS IS A NEW MODEL AND I KNOW IT'S DIFFICULT TO HAVE ALL PARTS AVAILABLE FOR A NEW CAR BUT A HEADLIGHT SHOULD BE SOMETHING THAT IS IN STOCK IN THEIR WAREHOUSE PRIOR TO SHIPPING THESE CARS TO THE PUBLIC.

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.

Get notified when new recalls or reliability data is added for the Chevrolet Corvette.
