My 2007 Buick LaCrosse, 3.8L V6 headlights turn themselves off at night, while I am driving. The bright lights stay on. The headlights do return after a few minutes but I do nothing to help. It is like magic. I know this sounds crazy but it’s happened twice now.
Answer: Body control module may be the issue. I suggest you to have a shop check for codes in the BCM.
