An issue with Mercedes-Benz’s MBUX infotainment system has prompted it to issue a recall for several thousand S-Class and EQS models in the United States.
The car manufacturer has revealed that deviations in the development processes of two different suppliers mean the MBUX system on certain vehicles may not operate as intended and fail to meet current production specifications. If the issue is present, the central display may not be activated as intended when the vehicle is unlocked.
In addition, the rearview camera image may not be displayed in the central display when the driver is reversing and instead, may remain black. The car then fails to meet Federal Motor Vehicle Safety Standard S5.5.3 that requires the rearview camera image to be available within 2 seconds of the reverse gear being selected and could, therefore, impair rear visibility that could increase the risk of a crash.

Mercedes-Benz received two field reports about a central display failure in November 2021 in EQS models and launched an investigation. It later initiated an investigation into S-Class models, noting that they too could experience the same issue.
The recall involves a total of 8,530 vehicles. They include a total of 13 Mercedes EQS 53 models built between July 13, 2020 and January 19, 2022, a further 13 EQS 580 models built between the same dates, a single EQS 450 built, 305 Mercedes S500s manufactured between July 13, 2020 and January 19, 2022, 8,019 examples of the 2021 S 580 built between the same dates, and 190 Mercedes-Maybach S580 units.
To resolve the issue, Mercedes-Benz dealerships will simply update the MBUX infotainment system. Dealers were notified of the impending recall on July 18, 2022 and owners will be notified before September 9, 2022.
