In my 2016 car, suddenly and sporadically, the main dashboard display and the radio sound itself all immediately shut off when I park and turn off the car. Obviously, these are supposed to remain illuminated and operational until the driver opens the door. I can't seem to recreate the problem deliberately. Usually, when I drive, park, and then turn off the car, all systems remain up as they are intended. But I'd say roughly 5-10% of the time I've driven the car in the last couple of weeks, this instantaneous shut-off has occurred. Ideas?
