2003 TOYOTA SEQUOIA SR5 Engine And Engine Cooling Problems

I NOTICED OIL LEAKING FROM REAR AXLE HOUSING. WHEN I TOOK THE VEHICLE IN FOR SERVICE I WAS TOLD THAT THE AXLE HOUSING IS LEAKING DUE TO DEFECTIVE WELDS AND MUST BE REPLACED, IT CANNOT BE REPAIRED. AT THE SAME TIME I WAS ALSO TOLD THAT THE VEHICLE FRAME HAS ROTTED FROM THE INSIDE OUT DUE TO DEFECTIVE OR INADEQUATE FACTORY RUSTPROOFING. I WAS TOLD THAT THIS PROBLEM IS PERVASIVE IN TOYOTA SEQUOIAS WHICH HAVE THE SAME FRAME AS TOYOTA TUNDRAS. TOYOTA HAS RECALLED THE TUNDRAS AND REPLACED THE FRAMES BUT TO DATE REFUSES TO DO THE SAME FOR SEQUOIAS. THE VEHICLE HAS BEEN DETERMINED TO BE UNSAFE TO DRIVE AT THIS TIME. ASIDE FROM THE DEFECTS STATED ABOVE THE VEHICLE IS IN EXCELLENT CONDITION. *KB

2003 TOYOTA SEQUOIA WILL UNEXPECTEDLY LOOSE POWER WHEN TURNING AND THEN ACCELERATION RACES UP AFTER A LONG PAUSE. THIS HAS HAPPENED ABOUT ONCE PER MONTH SINCE PURCHASING THE VEHICLE IN 2003 AND HAS SEVERAL TIMES RESULTED IN NEAR-MISS CRASHES FROM APPROACHING TRAFFIC AS THE VEHICLE WILL NOT MOVE OUT OF THE WAY OF ONCOMING TRAFFIC. *TR
