Sunroof spontaneously burst on June 6, 2018, around 7:25pm, my family and I were heading home a store, going North on mo-65 at about 65 mph in springfield, mo. Just South of battlefield rd, we heard a loud "pop" sound. We thought our daughter had hit her metal thermos against the back window. When we arrived home, however, I heard a crackling sound and traced it to the sunroof, which was shattered (like a spider web) and bulging at the top. Since then, as of 9am the following day, it has continued to bulge more, with a couple of small pieces of glass having popped out onto the top of the glass. It has not yet collapsed into the car, but I am leaving the sunroof shade closed so the glass doesn't fall into the cabin. Of note, the weather was mostly sunny, temperature around 80F. The sunroof was closed, as was the sunroof shade. Traffic was fairly light immediately around us. There were no large trucks nearby. No rocks or gravel was hitting the underside of the car, and there were no other sounds of anything hitting the car.
