I have a 2016 Focus ST1 that I bought new September 2016. It has 28,000 miles. I noticed today that the hard coat on both of my headlights is starting to peel right above the marker lights. Is that normal for them to peel this soon? Is it something that I can be warrantied? I live in Phoenix, so the sun shines here all the time, and my car is always parked in the sun.
