Hello, Iv'e done some looking and cant seem to find much detail on this issue. My wife drives an MKX and recently her headlight went out on the drivers side. The plug had got hot and basically burnt out. So I replaced it. I dont know if the adaptive headlights quit prior to that or not, as well dont think she realized it, but after replacing the clip and the bulb they now do not work.
The other thing is when you start the car they seem to focus or cross back and forth a time or two, well they still do that when starting, so I almost think they are capable of working. I looked for switches etc, and read the owners manual but dont see anything obvious. I was hoping just somehow they got turned off or whatever.
