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.

This has happened to me. Last week screens went blank at on cruise cont @110klm/hr then instantly rebooted. Car decelerated i presume as it lost cruise control. Today went to start and everything went black no response. Keys didnt work all electricals seem dead. Open and close doors and it rebooted to accessories mode. As soon as i pressed the start button it went dead again. Went back to accessories mode after opening doors and i spent 45 mins on the phone to Toyota on speaker phone. The car announced it was turning accessories mode off to save battery screens went blank andi then tried again and it started!
