I have a 20 Elite that we picked up new in June and about 7k miles on it now. Starting around August, we noticed popping sounds coming from various places around the windshield. It seems to be temperature dependent which is why I think it didn't happen until it started cooling off up here in New England. When it happens, the noises occur in clusters and very definitively from all directions around the windshield lasting on and off sometimes for several minutes. Anyone else experienced this?
