Sunroof spontaneously shattered. i was driving down the road around 40mph and suddenly heard a very loud noise. shortly after this, i heard my sunroof cracking above me. when i pulled over to look, i saw that my sunroof had shattered along the left, right and back of the sunroof. took it to the dealership and they estimate it to be around $1200-$1300 to fix. $800 for the glass by itself. there were no other cars around me when it happened and nothing above me that could have fallen and done this. if you have had this same issue, please contact scion to let them know so we can get a recall started. 1-866-707-2466.
