While driving on a major highway, my sunroof suddenly exploded. Luckily the screen was pulled shut otherwise I would have been covered in glass. I was able to drive to the next exit and park the vehicle to then get out and observe the damage.

There is a silver strip of "trim" running completely across the dashboard just above the radio controls. It is so reflective that a glare occurs periodically throughout the day when the sun hits it.
