I'm having the same issue on a 1.5 year old Eagle. I do live in central Texas, but we have had a reasonably mild summer for us, and my trailer stays under a three sided overhang all season. No sun hits the trailer unless we are camping. I'm having a hard time believing it's the heat issue. It twisted mine so hard it broke the led strip and half of the lights quit working. Taking it in for repair soon.
