Campaign No. 2024030007, March 2024

Revision A 04/04/2024

TO: ALL MERCEDES-BENZ CENTERS

SUBJECT

Model GLE/GLS (167 platform)

Model Year 2020 - 2023

Update Transmission Control Unit Software

Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2020-2023 GLE/GLS (167 platform) vehicles equipped with the 6-cylinder gasoline engine and 9-speed transmission, the transmission control unit software might not meet current production specifications. If a downshift of the transmission from 7th to 6th gear is not fully completed during a simultaneous slight braking maneuver of the vehicle, and additional conditions exist (e.g. aborted shift operation, low transmission oil temperature, simultaneous recuperation by the 48V starter-alternator), the engine might stall. In that event, the vehicle would lose propulsion which could increase the risk of a crash. When the vehicle comes to a standstill the engine can be restarted. This occurrence does not affect the functionality of the vehicle's steering and braking systems. An authorized Mercedes-Benz dealer will update the transmission control unit software on the potentially affected vehicles.

Prior to performing this Campaign:

VMI must be checked before performing campaigns to verify that the campaign is required on a specific vehicle. Always check for any other open campaigns and perform accordingly.
Please review the entire Campaign bulletin and follow the repair procedure exactly as described.

Approximately 104,851 vehicles are affected.
