2003 TOYOTA SEQUOIA SR5 Structureframe And Members 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

MY 2003 TOYOTA SEQUOIA IS EXPERIENCING HEAVY FRAME RUST, TO THE POINT OF BEING A SAFETY CONCERN FOR THE INTEGRITY OF THE FRAME AND UNDERCARRIAGE. I AM FILING THIS COMPLAINT THAT IT IS MY UNDERSTANDING THE SEQUOIA AND TUNDRA FRAMES ARE IDENTICAL AND BUILT BY THE SAME FACTORY. THE SAME MODEL YEAR TOYOTA TUNDRA'S HAVE BEEN RECALLED FOR HEAVY FRAME RUST, BUT THE SEQUOIA'S HAVE NOT. I FEEL THAT THE SEQUOIA MODELS ARE SEEING THE SAME RUST PROBLEM FOUND ON THE TOYOTA TUNDRA'S AND SHOULD LIKEWISE BE RECALLED AS WELL. *KB
