The 2021 to 2023 Mercedes-Benz GLB-Class received a four-star overall rating from NHTSA's New Car Assessment Program for US-market vehicles. The model earned four stars in frontal crash protection and rollover resistance, while achieving five stars in both side crash and side pole crash tests. NHTSA applies these ratings across model years until a significant redesign occurs, so this assessment covers the entire 2021 to 2023 range.
