I was driving 70mph on AZ state route 51. I heard a loud bang, like a gun shot, and a sudden noise like turbulent air and highway noise. As I slowed the vehicle I looked around to see if there were any broken windows which there weren't. pulling over and inspecting the vehicle I noticed 2/3 of the moonroof was missing and a few pebbles of plate glass on top of the inside cover. The remaining glass was angled up like it had been sucked up not deflected down from an impact. I was a navy fighter Pilot and this is the same sequence of events I experienced with the loss of a canopy and sudden decompression. I have a master's degree in aerospace engineering and I know the location of the moonroof is a low pressure area like the top of an aircraft wing. There were no other vehicles in close proximity, no objects flying off the road, nor was the vehicle under an underpass. This is a combination of a design flaw and possibly a defect in the moonroof glass. The vehicle is 3 months old, less than 3000 miles driven and the moonroof has never been opened. Acura takes no responsibility. This is a safety hazard as a less experienced startled driver could be so distracted as to cause an accident. The fix is a wind deflector in front of the moonroof. I am having one installed at my expense by the Acura. I would prefer a metal sunroof or a factory roofline modification to deflect the airstream and prevent the low pressure area causing this problem. Googling moonroof explosion yields numerous incidents from multiple manufacturers. There needs to be a fix before a fatality occurs. Captain, usnavy(ret)
