I had the problem on my 2014 (production date 10/13). Mine is white and at about 18 months old (spring 2015), I started noticing blotches & dullness "creeping" down from the top. I immediately started taking pictures and sending them to Prime Time showing them the progression over the next several months. At first they tried to say that "the white caps don't do that". After several emails back & forth and series' of pictures showing the progression, they finally saw it & agreed to take care of it (think extensive paper trail). By now, it was fall 2016 and I told them I was planning a trip to Indiana in June 2017. In March/April 2017 I contacted them to arrange an exact date. They told me I was out of warranty and there was no agreement they could find because the person I was communicating with (emails & pics.) no longer worked there. I gathered & resent ALL the related emails & pics showing that they agreed to "take care of it". Needless to say, when I arrived, they had a newly PAINTED front cap ready and a day & a half later I left with a new front cap!
