THE MOTORCALIBER REVIEW
MotorCaliber editorial ◆ Reviewed against NHTSA data ◆ 2026-10-01

The Mercedes-Benz GLB-Class is a compact luxury SUV that punches above its size by offering three-row seating in a relatively small footprint. Aimed at young families and urban professionals who want premium brand cachet without stepping up to a full-size hauler, the GLB slots neatly into one of the most competitive segments in the American market, blending European refinement with genuine everyday practicality.

The 2023 Mercedes-Benz GLB-Class achieves an exceptional safety performance, earning a MotorCaliber NHTSA Safety Index score of 91 out of 100. This places it in the highest tier of vehicles reviewed. Its side-impact crash test rating is a perfect 5 out of 5 stars, providing robust protection in a common collision scenario. Both frontal and rollover evaluations resulted in 4 out of 5 stars. Notably, across four model years (2020-2023), the GLB-Class has zero recalls. This indicates a high level of manufacturing consistency. Owner complaints total 82 over the four-year period. Within these complaints, 4 crashes, 5 injuries, and 1 fire were reported. The 2023 GLB-Class stands as a strong safety contender in the compact luxury SUV segment.

WHAT REVIEWERS SAYReviewers generally regard the GLB-Class as a distinctive and practical choice in the compact luxury SUV space, praising its unusual three-row seating option and premium interior quality. Most find the driving experience refined if not particularly sporty, and the upscale brand positioning is seen as a genuine asset. Criticisms typically center on the relatively compact third-row space and infotainment learning curve.
