Replace Transmission Bearing Cover

This is to notify you of the Service Campaign Launch to replace the bearing cover on the transmission in 2,992 Model Year (“MY”)
2020-2021 GLA-Class and GLB-Class (156/247 platform) vehicles. The vehicles will be visible and flagged in VMI as “OPEN” on
December 9, 2022.

Background

Issue

Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has
determined that on certain MY 2020-2021 GLA-Class and GLB-Class (156/247
platform) vehicles, the transmission bearing cap cover does not correspond to
current specifications. Over time, the transmission bearing cover may loosen, which
may result in minor oil loss. An instrument cluster transmission light will still alert the
user if it falls below the threshold and alert the driver if the transmission oil
overheated. The indicator light will alert the driver to drive with caution. A risk of
fire can be ruled out.

What We’re Doing

MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will
replace the transmission bearing cover.

Parts

The remedy is available and can be performed as necessary.
