DRIVER'S SIDE POWER WINDOW WAS INOPERATIVE. THE DEALER WAS NOTIFIED, AND STATED THAT THE FOUR WINDOW CLUSTERS FOR ALL THE WINDOWS HAD TO BE REPLACED TO GET THE DRIVER'S SIDE WINDOW TO OPERATE. THE CONSUMER WOULD LIKE TO KNOW WHY ALL FOUR WINDOW CLUSTERS HAD TO BE REPLACED. ALSO, THE POWER STEERING FLUID LEAKED FROM THE HOSES/CLAMPS, AND CONNECTORS. THE LEAKS APPEARED MORE FREQUENTLY DURING THE WINTER SEASON WHICH CAUSED THE METAL TO EXPAND. THE DEALER/MANUFACTURER WERE NOT NOTIFIED AT THIS TIME. *AK *SCC *JB
