2005 Toyota 4RUNNER wipers, windshield & visibility problems

Front passenger side glass "exploded" while driving on the interstate in montana. There were no other vehicles in the area of our toyota when the glass broke. Nothing such as a bird or rock struck the glass it simply shattered! Driver and passenger cut by flying glass, but not badly injured.
