NHTSA Complaint #10139110 — 2004 TOYOTA COROLLA

I WAS DRIVING A TOYOTA 2004 COROLLA ON THE HIGHWAY @ 60 MPH. ALL THE CAR WINDOWS WERE OPEN. THERE WERE NO OTHER CARS/TRUCKS NEAR THE CAR. I PUSHED THE BUTTON TO CLOSE THE WINDOWS. THE DRIVER SIDE WINDOW WENT UP TO APPROX. 6" FROM THE TOP OF THE WINDOW AND STOPPED. I PUSHED THE BUTTON TO TURN IT DOWN. THE WINDOW RETURNED DOWN. I AGAIN PUSHED THE BUTTON TO CLOSE THE WINDOW. AS THE WINDOW WAS RAISED TO APPRROX 6" FROM THE TOP, THE GLASS EXPLODED. I DROVE DIRECTLY TO THE TOYOTA DEALER WHO SAID SOMETIMES THIS HAPPENS AND WAS NOT ABLE TO GIVE A REASON FOR THE OCCURRENCE. THE WINDOW WAS REPLACED. I AM AFRAID TO TOUCH THE WINDOW AS WHEN THE GLASS EXPLODED, MY HAND WAS CUT, SOME OF THE GLASS WAS IN MY LAP. I WAS WEARING SUNGLASSES WHICH I THINK PROVIDED SOME PROTECTION. WHEN I SAW THE BACK OF THE CAR THERE WAS GLASS ON THE FLOOR AND BACK SEAT. FORTUNATELY, I DIDN'T PANIC WHEN THE GLASS EXPLODED. I AM FRIGHTENED TO THINK OF THE SERIOUS CONSEQUENCES IF I DID. ARE THERE ANY REASONS FOR THIS TYPE OF OCCURRENCE? THERE WASN'T ANY UNUSUAL SOUND WHEN I PUSHED THE WINDOW BUTTONS. IS THERE A PROBLEM W THE TOYOTA 2004 COROLLA? THANK YOU FOR YOUR HELP. *JB
