1. Transmission Problem Vehicle Rolls backwards when the gear / transmission is in "Drive". It happens in these two situations: a) I am stopped at a Traffic Light which is Red. The road is at a moderate upward incline. When the Light turns Green, and I move my foot from the Break pedal to the Accelerator to move forward, the GLB rolls backwards even though the transmission is, and has been, in "Drive". b) I am backing out of my garage. Our driveway is at a moderate Backward / Downward Decline. As I reach the point where I shift the gear into "Drive", the car still continues to roll backwards. This is despite the fact that I had to depress the Brake pedal to place the vehicle in Drive. c) I have checked the settings and confirmed that the transmission is NOT in manual mode. The problem is happening when the Transmission is in automatic mode. I have been cautious and prevented an accident over the last 6 months that I have owned this car. ___________________________________ 2. Cruise Control: This is a situation is that I am driving, and I have the Cruise Control "On". I encounter the traffic to be slowing, so I push the "Cancel" button for the Cruise Control in the left bar of the steering wheel. As I manipulate the wheel to make a left turn, the "Resume" button, also in the left bar of the steering wheel, gets touched without my realization. The GLB zooms ahead violently! This is dangerous and unexpected acceleration. A corollary to this malady is that the radio suddenly blasts loud as I manipulate the steering wheel to make a right turn. The radio volume button in the bar of the steering wheel gets touched without my realization. This is dangerous. It can make the Driver jump and react suddenly to the unexpected loud noise. I REPORTED THESE 2 PROBLEMS TO MERCEDES BENZ OF NORTH AMERICA THROUGH THE WEBSITE IN DETAIL AS ABOVE ON DEC 9, 2024 THE SITE PROMISES A RESPONSE IN 24 HOURS. I HAVE NO RESPONSE

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.
