Service bulletin NCU - 2023070020

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

This is to notify you of the Service Campaign Launch to update the software for various control units in 14,462 Model Year (“MY”) 2022-2023 EQS (297 platform) vehicles. Vehicles were visible and flagged in VMI as “OPEN” on August 22, 2023. An additional 12,445 vehicles were visible and flagged in VMI as “OPEN” on September 15, 2023. An additional 2 vehicles will be visible and flagged in VMI as “OPEN” on March 8, 2024. Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2022-2023 EQS (297 platform) vehicles, the software for various control units does not meet current specifications. An extensive optimization update will be implemented on the affected vehicles. Also, a special procedure has already been implemented in Xentry. The software updates will include, but are not limited to, increased system robustness, increased augmented reality camera quality, implementation of the Zync-App for video streaming via the head unit, and implementation of Dolby Atmos for an improved audio experience. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the control units.
