(sun roof glass exploded) at 400pm we were traveling North on US65 at 65 mph, the sun roof was in the tilted open position, the nearest traffic to our location was 500 yards ahead of us. The music was playing and the four vehicle occupants were relaxed and talking. Suddenly with a very loud sound the sun roof glass exploded/shattered covering all occupants in glass shards. The driver maintained complete control on the vehicle and made an immediate emergency stop. The passenger front occupant injured her neck during the violent reaction from the sound/explosion and covering in glass and will need treatment. Nothing struck the vehicle!!! this failure was caused by the sun roof and needs to be addressed by Mazda and the glass supplier. The type of failure could very well cause a serious accident and could cause loss of life. The sun roof glass should be re-enforced to prevent glass from spraying on the vehicles occupants. We have contacted Mazda North America and were offered a $250 good will amount, money was never our issue of concern, this is a very serious safety issue and the root cause should be found and corrected before someone gets seriously injured. This type of failure is noted in many accounts on the internet and needs to addressed.
