Side/rear Glass problems of the 2010 Honda CR-V

I purchased a 2010 Honda cr v in November of 2009. In January the vehicle had around 2300 miles. My wife and I took a vacation and left the vehicle parked in her parents private driveway. Four days into our vacation, my father-in-law noticed that our drivers side window was "foggy looking". He got closer to the vehicle and noticed that the tempered glass window was spider-ed and pushed out toward the exterior of the vehicle. He took the vehicle to the dealer and they replaced the window. The dealer would not honor our warranty, but still replaced the window. I believe this was a manufacturing defect. I also believe this could be serious if it happens when someone is driving down the road and this defect occurs.
