I HAD TWO EVENTS OF FAILED FRONT DOOR WINDOWS ON 2004 PONTIAC VIBE ONE WITH BROKEN GLASS ALL OVER DRIVERS SEAT, RECEIVED ONLY MINOR CUTS CLEANING UP AS FAR AS I CAN TELL THE WINDOWS CAME OUT OF THE TRACK AND WITH GREAT FORCE SHATTERED. *JB INTO MANY PIECES. THE SECOND TIME THIS HAPPEN IT DID NOT BREAK ONLY CAME OFF TRACK. THE LOCAL WINDOW COMPANY WOULD NOT REPAIR DO TO REPUTATION OF THIS HAPPENING. THEY TOLD ME TO TAKE IT TO A DEALER, WHO REPAIR IT. BOTH TIMES THIS HAPPEN WHEN VEHICLE WAS STOPPED. I WOULD HATE TO THINK WHAT COULD HAVE HAPPENED IF THE CAR WAS IN MOTION. THE 2ND TIME THIS HAPPENED AND ONLY CAME OFF TRACK WAS RECENT AND HAS NOT BEEN REPAIRED YET. I'LL WAIT TO SEE IF I HEAR FROM YOU BEFORE ITS REPAIRED. *JB
