What's wrong?
On the 2021-2022 Mercedes-Benz Eqs 580, Eqs 450, S 580, and S 500, the rear signal acquisition and actuation module software controls signals sent to rear exterior lights. That module is the electronic controller that tells the rear turn signals, hazard lights, and reverse lights when to switch on. Those lights tell nearby drivers when the vehicle is turning, stopped with hazards active, or backing up.
In affected vehicles, the software does not meet current production specifications because of a supplier development process deviation. During initialization, the module can fail to control the rear signal functions correctly. When that happens, the rear turn signals, hazard lights, and reverse lights can be disabled even though the driver still expects them to work.
The driver can see several warning messages in the instrument cluster before or when the problem appears. Treat those messages as the warning sign for this lighting defect.
