# Service bulletin SC\-2022030031

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

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
