Add me to the exploding sunroof club. It happened today, driving 40 mph in 45 degree sunny weather. My front panoramic sunroof spontaneously exploded. Outwards. Loud boom. Looked around, no one nearby. Stopped at light looked up saw blue sky and shattered glass. Pulled over to a safe place, took photos, called Lexus. Their first response was to call my insurance company. I asked why, I had photos that showed it was obviously blown out from inside the car. After a 45 mi it's chat with Corporate, I have a case number. Car is not at dealer.
