I have had my car for about a month. I noticed that at some times the instruments seemed to flash off and on for a split second. I thought at first this was just some glitch or issue but there was nothing wrong with the car otherwise.
This morning I had the headlights on "auto" and went under a long (darker) underpass. Just after the darkness set in, the instruments flashed, then when I hit sun again, flashed again. It then dawned on me (pun intended) that it was the car switching from the running lights only to headlights on in the dark, then headlights off in the light.
Not sure if this is your issue but thought others might have experienced the same thing and not figured it out.
