The glass panel between the windshield and the sunroof spontaneously shattered. I wasn't aware of this and had just noticed increased wind noise while driving for a few weeks until I noticed that it was due to shattered glass panel. It is cracked almost all around and somewhat dislocated. Upon close inspection in can be seen that cracks run throughout the glass panel. There is no single point of impact of a possible foreign object, so I can rule out the possibility of something hitting it with high confidence. I took it to the dealership but they refused responsibility under manufacturer warranty, claiming it must have been an object hitting it and quoted $3,815.10 for repair. I have detailed pictures showing no impact marks.
