Purchased a 2016 SL August 2019. Car was originally from Washington. We always use the switch and turn the lights completely on when we are driving. What I've noticed recently is that with the car off the headlights will start flickering and strobing randomly then stop. Sometimes when you first turn the car on with the light switch in the off position the lights will strobe and flicker. Has anyone else dealt with this? I drove the car to work this morning and I've had two people tell me the lights are flickering with the car just sitting there. When I go out and look they've been off.
