Mercedes\-Benz AG \(?MBAG?\), the manufacturer of Mercedes\-Benz, has determined that on certain MY 2019 GLC\-Class, and GLE\-Class \(253, and 292 platform\) vehicles, the automatic transmission does not meet specification, and thus the possibility exists that a hard and delayed shift operation may occur.
