I had this issue when I first got my 2016 All Terrain. I had contamination in the drivers side headlight lens and a deep scratch in the passenger side headlight lens. I used to work at the dealer, last day was yesterday, and they changed them for me on warranty. The all terrain lights are expensive though! I checked my cars history the other day and pulled the warranty card of the system, the headlight cost to our dealer was $1657 per light! The total value of the warranty claim including labour was $4,000!!
