Radio going black and EPS light comes on and car won’t start

Hello, it sounds like an electrical power issue. The battery may have lost charge, and the charging system may not be functioning properly. Start by checking the battery for state of charge and the ability to take a charge. If this fails, replace the battery. Once a known good battery is in place, have the charging system checked to ensure it is recharging the battery as needed continually. I would suspect any warnings and component failures will resolve once electrical power is restored as needed.
