Get it fixed now! We got a chip in Dallas on Monday and pulled over immediately. While looking up Safelite's number, the chip spread into an 8 inch horizontal split as we watched. Safelite said they don't repair cracks bigger than a dollar bill, so we moved on. The crack is now 3 feet long, mostly in the black bottom area out of sight. I'm not changing a windshield on a 3 month old car, since it's not a visibility issue. Our deductible is $200 and we have accident forgiveness, so we'll just change it at our first annual service in December.
