While driving a vehicle on the highway, the sunroof exploded violently. The large, moving piece of the panoramic sunroof appears to have broken outwards. Large pieces of glass and smaller pieces landed in the front and middle of the cabin, including on the driver. Small chunks of glass landed on and cut the driver of the vehicle. A loud sound occurred. This was very startling, the glass was very dangerous, and we were lucky that no one was in the middle seats where the glass primarily fell. This occurred in a temperate (high 60s or low 70s F) climate and with no prior damage to the glass. No sign of an impact from anything on the glass. The sunroof cover was pulled back while the glass was in the closed position. The vehicle is at the dealer and we are reaching out to the manufacturer.
