Service bulletin NCU-OTA051923

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 2021-2023 EQE, EQS, EQS SUV, and S-Class (223, 295, 296, and 297 platform) vehicles, the software of the sound system does not correspond with the latest series production configuration. The software update serves as the necessary preparation for additional functionalities that will be included in the future to improve and expand the sound system of the vehicles. The update is free of charge and will be carried out in the background. The installation will take approximately 3 minutes, the system can be used without restrictions during this period. The new software will be active during the next driving cycle. What We’re Doing MBUSA will conduct an OTA service campaign. Remote software updates are automatically downloaded and installed in the customer’s vehicle free of charge without an additional workshop visit via the data link of the communication module. All customers will be mailed a letter informing them of this software update.
