WHILE ACCELERATING TO 70 MPH ON AN ON-RAMP TO I-40, I HEARD A VERY LOUD POP. I HAD MY SUNROOF COMPLETELY OPEN (WITHDRAWN INTO VEHICLE ROOF) AND WINDOWS DOWN AT THE TIME. AFTER HEARING THE LOUD POP, I CHECKED TO SEE IF A ROCK HAD STRUCK MY WINDSHIELD, AND COULD FIND NO EVIDENCE OF SUCH. WHEN I WENT TO CLOSE MY SUNROOF, I LOOKED UP TO SEE THAT THE GLASS HAD COMPLETELY SHATTERED IN-PLACE. I WAS ABLE TO COMPLETELY CLOSE THE SUNROOF AND PULL THE INTERNAL COVER CLOSED, AND PULLED OFF THE HIGHWAY. THE VEHICLE WAS IMMEDIATELY TOWED TO A MAZDA DEALERSHIP, WHO IS CONTACTING MAZDA TO WORK ON THE SOURCE OF THE PROBLEM. *TR
