Service bulletin NCU-2023120012

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 vehicles, has released a software update for certain MY 2021 S-Class (223 platform) vehicles that allows for future remote software updates on additional control units. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the Communication Module software.
