2007 BMW 328I User Comment / Complaint

I was driving on the highway and a rock flew up from the road and hit my windshield. when i got home, my dad noticed a chip in the corner of my windshield. the next day, the chip formed into a crack over a foot long. i had to get my windshield replaced. it has only been two weeks with my new windshield and the other day i was hit by a rock again, creating another chip. so far, there is no crack. and i found forums that people also had this same issue.
