I WAS DRIVING DOWN THE HIGHWAY AND FOR NO APPARENT REASON, MY SUNROOF EXPLODED AND SHATTERED INTO TINY PIECES. THE NOISE WAS LIKE A GUNSHOT AND GLASS CAME INTO THE CAR BECAUSE THE VISOR WAS OPEN AT THE TIME. I DID NOT LOSE CONTROL OF THE CAR, BUT THE NOISE DID CAUSE ME TO BE DISTRACTED AND DISORIENTED FOR A SHORT TIME. IF THERE HAD BEEN MORE TRAFFIC, IT MIGHT HAVE BEEN A LOT WORSE. I CAN NOT ATTRIBUTE THE EVENT TO ANY WEATHER CONDITION OR VEHICLE USE CONDITION. *TR

SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DISC:ROTOR
WHILE DRIVING AT 55 M.P.H. GOING DOWNHILL AT A 6% GRADE VEHICLE'S FRONT END AND STEERING COLUMN STARTED VIBRATING VIOLENTLY. PULLED OVER AND LET CAR SIT FOR 30-45 MINUTES, THEN TRAVELED ON. TOOK CAR TO BUICK DEALER AND FOUND ROTORS SEVERELY WARPED. ROTORS WERE TURNED(MACHINED) AND CAR BRAKES WERE OK FOR NEXT 2-3000 MILES. DRIVING AT 55M.P.H. NOTICED PULSATION/VIBRATION WHEN APPLYING BRAKES. TOOK CAR TO LOCAL DEALER AND THEY DID NOT SEEM IT WAS ANYTHING TO WORRY ABOUT. DROVE CAR AT 55 M.P.H. ON HIGHWAY AND VIBRATION AND PULSATION BECAME WORSE. TOOK CAR TO A NATIONAL RETAILER AND HAD TO HAVE ROTORS REPLACED WITH HEAT DISSIPATING ROTORS. CAR SHOULD HAVE HAD THESE TYPE ROTORS TO BEGIN WITH DUE TO SIZE AND WEIGHT. THIS PROBLEM COULD CAUSE A FIRE OR THE INABILITY TO STOP WHEN NEEDED, CAUSING POSSIBLE SERIOUS ACCIDENTS. *KB
