Summary

Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz, has determined that on certain MY 2019-2020 CLA-Class, A-Class, and GLB-Class (118, 177, and 247 platform) vehicles, the transmission control unit software may not correspond to current product specifications. It is possible that the vehicle may switch to coasting mode during deceleration or rolling when engaged in drive mode “E”. In drive mode “E”, coasting operation is displayed in the instrument cluster as “D” and may be green instead of white. When exiting coasting mode, the “N” drive mode instead of “D” may be activated. The current drive mode will be displayed in the instrument cluster. What We’re Doing MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the transmission control unit software.

Owners of these vehicles have filed 7 complaints in the transmission category.
