I'm going to have the windshield replaced ('18 with 1200 miles, IR windshield). This is my second crack. The first was "glued" and has held. This one elongated and now covers over 10 inches across. Insurance will cover. I saw another mention of a windshield replacement here. Anyone else with this problem? Is the glass very thin for some reason? Manufacturing defect? In 32 years of driving I've never had to replace glass, now twice in a month and no I'm not trailing 18 wheelers or driving off road....
