I was driving up a clear road, heard and exploding sound and witnessed my drivers side window shatter. The glass that was not protected by tint, I could hear crumbling into the frame. I could not see out of my window and thankfully did not swerve due to scare of the explosion sound.

Is the TSB_2078939_1 repair free?
