By owner complaints filed with NHTSA, the Mercedes-Benz GLB-Class model years with the most are the 2020 (63), 2022 (14) and 2023 (14). Newer model years have had less time on the road, so their counts are naturally lower; compare years of a similar age.
Which Mercedes-Benz GLB-Class years have the fewest complaints?
