My car has actually shut the whole electrical off for few seconds while driving. The battery keeps going dead constantly telling me my brakes are bad or says my power steering is bad. But brakes are fine and so is steering power steering
I have a 2020 Sport and my dash would light up saying all the assistance features randomly stopped working (ACC, LKAS Road Mitigation, etc.), electric power steering went out, drive modes are unavailable, etc. But when i shut it off for a few, lock it, unlock it open and close the driver door and cut it back on, everything is back to normal.
