Electrical issues with the 300 series


Recommended Posts

Has anyone had intermittent issues with the 300 where the electrical systems seem to go into meltdown. Randomly when starting the car the dash just goes black and we loose all power. Other times we get a series of warning lights including loss of braking power, pull over and call your dealer. Both issues then get reset randomly when you leave the car for a while, lock and unlock doors etc. 

The dealership cannot find any codes when they run a diagnostic and of course it doesn’t happen when they have the car.
