I had a crack develop recently but my dealer showed me how it was caused by a small stone chip and not a stress fracture(which Mazda would have covered). It slowly spread from the left A pillar at eye level about 3-4 inches a day so I contacted my insurance agent to proceed with a replacement claim. Now, my dealer warned me that there are some aftermarket windshields out there with minor fitment issues, but more importantly, with wiper defrost wires that are shorter than oem and therefore when connected up to the onboard connector it can be so tight it could slowly peel the defrost wires off the underside of the windshield. I explained this to my insurer and said they could contact my dealer to confirm this but they immediately agreed to purchase on oem windshield for a replacement. Yahoo!!
