While traveling down I81 at approximately 65 mph a small pebble tapped the windshield on the passanger side and it cracked. Within 24 hrs it has grown half way across the window. Planning on having it replaced within five days. Going down highway 31 at approximately 35 mph three days after the first crack another rock hit the windshield and the same thing has happened on the drivers side. ( windshield had not yet been replaced) as well as one month of purchasing the car a small rock hit the top of the windshield in the rear view mirror area and only made a small ding in it. I believe these windshields are very dangerous. If you hear anything hit your windshield and you see nothing initially, please stop asap and inspect it as these line cracks expand very fast. Not knowing if these windshields contain the ability to stay together if it shaders. I have a small child, this could become devastating very fast. Please stay aware of the smallest hits to these windshields. Concerned for all.
