After picking up children from school, I was driving out of the parking lot down a slow-speed arterial road (35 mph posted speed limit). Roughly 30 seconds after reaching the posted speed limit we heard a loud bang (like a gunshot) and immediately pulled over. The middle section of the panoramic sunroof had shattered. Upon examination on the side of the road there was no apparent impact spot or item in the roadway that would have indicated that particular section of the roof had been struck by anything (no rock, branch, brick, etc), nor were there any other vehicles in the vicinity that might have kicked up an object to hit the roof and nothing else. The sunroof appears to have spontaneously shattered without warning. The temperature outside was moderate (roughly 60 degrees) and the car had been driven earlier in the day without incident. A police report was filed for potential vandalism and I'm currently waiting for the insurance company to contact me to discuss and inspect.
