We were driving our 2008 Acura MDX on the open highway at 60 mph with the moonroof in the tilt position. No other vehicles were close. The moonroof glass suddenly exploded, sending glass both outside and inside the vehicle. The moonroof had a jagged hole about 8" by 18" with some outward bulge. Glass shards were through our hair, but fortunately did not get into our eyes. In the absence of any visible object hitting the glass, we conclude that the moonroof glass was likely defective and could have caused a very serious accident if the flying shards had blinded the driver.
