Warning lights on the dashboard illuminate without an apparent cause.

Simultaneously, warning lights on the dashboard illuminate, indicating issues without a clear trigger.

The problem also extends to occasional difficulties starting the car, and there have been instances of unexplained battery drain, even after a short period of non-use.

My 2012 ML350 has experienced problems with the SAM (Signal Acquisition Module) which is mounted behind the right tail light. When it gets wet the fuel gauge and other electrical components stop working. Give it a few days to dry out everything returns to normal.
