August 28, 2017: When I flicked my signal to turn the headlights went out for seconds. It went black outside. As I was making turns the lights came back on, until the signal flicked back into place and then the headlights went out again for a couple of secs.
I booked an appointment with the dealership and will post anything that comes back. I'm hoping it has to do with my outstanding issue posted above. Apparently a bad BCM can cause battery drain, of which could promote vibrations upon cold start.
