NHTSA Complaint #10106037 — 2000 TOYOTA SIENNA

THE ENGINE IN MY 2000 TOYOTA SIENNA HAS A DEFECT THAT CAUSES ENGINE OIL JELLING AND LEADS TO A TOTAL FAILURE OF THE ENGINE. THE PROBLEM FIRST OCCURRED AT 38000 MILES WHILE STILL UNDER THE NEW CAR WARRANTY. TOYOTA FIXED THE PROBLEM BY CLEANING THE SLUDGE FROM THE VALUE AREA OF THE ENGINE BUT THIS DID NOT ELIMINATE THE PROBLEM. AT 68000, THERE WAS A COMPLETE FAILURE OF THE ENGINE THAT WAS A RESULT OF ENGINE OIL GELLING. A TOYOTA TECHNICIAN WHO INSPECTED THE CAR STATED THAT THERE IS SCARING OF THE INTERNAL ENGINE PARTS THAT INDICATE A HISTORY OF OIL STARVATION. THE OIL STARVATION PROBLEM THAT CAUSED THE ENGINE FAILURE IS DUE TO OIL GELLING PROBLEM. TOYOTA HAS AGREED TO EXTEND THE WARRANTY ON MY VEHICLE TO COVER THIS PROBLEM FOR A PERIOD OF EIGHT YEARS WITH UNLIMITED MILEAGE, HOWEVER, THEY ARE NOW REFUSING TO HONOR THIS WARRANTY.*AK
