Update Powertrain Control Unit
Software
This is to notify you of the Service Campaign Launch to update the powertrain control unit software on 1,876 Model Year (“MY”)
2022 EQS-Class (297 platform) vehicles. The vehicles will be visible and flagged in VMI as “OPEN” on April 8, 2022
Background
Issue
Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz, has determined
that on certain MY 2022 EQS-Class (297 platform) vehicles, the powertrain control unit
software may not correspond to current product specifications. It is possible that the
vehicle may not enter into “READY” mode and if so, the vehicle would not start. In
addition, a warning message may be displayed (e.g. "Towing prohibited", battery
symbol with text "Fault", "High-voltage electrical system fault", or “error message
about the 12V battery”) in the instrument cluster.
What We’re Doing
MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will
update the powertrain control unit software.

The Remedy is available and can be performed as necessary.
