Maybe its just me, but I have now been through 3 windshields in this van, it seems excessive to me and I was wondering if this was a common occurrence, as I never had had any trouble like this in any previous vehicles, and I have owned alot of brands and types. It seems to star very easily if a nearly invisible rock hits it, maybe the angle? After a few stars it them proceeds to crack horizontally across the entire piece from side to side. I have had safelite replace them before, and will have to do it again before the end of the year I guess. When they star I do immediately put clear nail polish over the crack to keep the moisture out, and I avoid putting full heat on defrost as that seems to cause it to stress crack. All paved roads up here, no gravel, but occasional potholes which I try to avoid.
