I am from Nanaimo, BC, just bought a new 2017 mustang convertible straight from the factory. My front and side windows are blotchy showing dime size white blotches. These are only visible when the sun hits the windows the right way. The dealership is aware of the problem, some of the other mustangs are showing the same problem and some are not. Waiting to hear back from them but I am curious if any other mustang owner has had this same problem.
