TOYOTA CLAIMS DENIED BECAUSE SERVICE NOT PERFORMED AT TOYOTA. ESTIMATE FROM DEALER FOR REPAIR IS $8,300. THERE APPEARS TO BE SOME OTHER PROBLEM WITH THIS ENGINE BUT THEY WON'T INVESTIGATE FURTHER DUE TO SLUDGE EVEN THOUGH I CAN PROVE PROPER MAINTENANCE.*AK

WHILE DRIVING RIGHT SIDE AUTOMATIC SLIDING DOOR WILL COME OPEN BY ITSELF. WHEN VEHICLE IS PUT INTO DRIVE DOOR WILL MAKE A NOISE LIKE IT'S NOT SHUT. DEALER CONTACTED.*AK *YH

OIL LIGHT FAILED TO REPORT MAJOR ENGINE SLUDGE PROBLEM BEFORE THERE WAS SEVERE ENGINE DAMAGE. THE DAMAGE IS REPORTED BY THE TOYOTA DEALER AS $8900.00 TO REPLACE THE ENGINE IN A CAR WITH ONLY 20,181 MILES. THE LIGHT FLASHED FOR A SPLIT SECOND AND NEVER TURNED ON AGAIN. THE OIL LIGHT FAILED TO INDICATE LOW OIL PRESSURE IN THE SYSTEM CAUSING CONSIDERABLE DAMAGE.*AK

WHILE DRIVING ENGINE CHECK LIGHT CONTINOUSLY ILLUMINATES. OIL TURNS TO THICK SLUDGE LIKE SUBSTANCE, AND BLUE BLACK SMOKE COMES FROM TAIL PIPE. PLEASE PROVIDE ANY FURTHER INFORMATION. *AK

I BELIEVE ENGINE SLUDGE COMPLAINTS ARE FICTICIOUS.*AK

WHITE SMOKE COMES OUT OF THE TAILPIPE WHEN THE ENGINE IS STARTED. TOYOTA DEALER SAYS THAT THE RINGS ARE BAD DUE TO SLUDGE IN THE ENGINE. THEY, AND TOYOTA CORPORATE OFFICE, SAY THAT THE SLUDGE IS DUE TO NEGLIGENT MAINTENANCE. HOWEVER, OIL CHANGES WERE MADE AT THE PROPER INTERVALS ACCORDING TO THE OWNER'S MANUAL. THE DEALER SAYS THAT REPAIRS WILL COST BETWEEN $2300 AND $5700 AND THAT THE WARRANTY IS VOIDED BY THE PRESENCE OF SLUDGE. I TRIED, UNSUCCESSFULLY, TO CONVINCE THEM THAT THIS LEVEL OF SLUDGE BUILD-UP WAS NOT REASONABLE FOR AN ENGINE OF THIS AGE. I'M AT A LOSS AS TO WHAT TO DO TO GET TOYOTA TO HONOR THEIR WARRANTY. THIS SEEMS LIKE FRAUD TO ME. IS THERE ANYTHING THAT NHTSA CAN DO? GIVEN THE NUMBER OF COMPLAINT THAT I'VE SEEN ON THIS SITE REGARDING THIS PROBLEM, I THINK SOME GOVERNMENTAL PRESSURE WOULD HELP TO GET TOYOTA TO DO THE RIGHT THING.*AK

CONSUMER WAS PULLING UP IN DRIVEWAY AND NOTICED THAT THERE WAS WHITE SMOKE COMING FROM UNDERNEATH OF VEHICLE. SHE TOOK IT TO GAS STATION, AND MECHANIC TOLD HER THAT OIL WAS LESS THAN THREE QUARTS LOW. DEALERSHIP WAS AWARE OF PROBLEM. *AK

NOTICED WHITE SMOKE UPON STARTING CAR FOR A COUPLE OF DAYS. THE FOLLOWING SUNDAY, THE OIL PRESSURE LIGHT CAME ON WHILE TRAVELING-STOPPED AND PUT IN 1 QUART OF OIL, LIGHT WENT OUT. THE FOLLOWING MONDAY, THE ENGINE CHECK LIGHT CAME ON. THE NEXT MORNING, TUESDAY I TOOK THE CAR TO THE NEAREST TOYOTA DEALER AND WAS TOLD THAT OUR ENGINE WAS FULL OF SLUDGE DUE TO IMPROPER OR LACK OF MAINTENANCE. THE REPAIRS WERE NOT COVERED UNDER THE WARRANTY. WAS GIVEN AN ESTIMATE OF $9K TO REPLACE THE ENGINE OR $5500 TO REBUILD THE ENGINE. WE THEN TOOK THE CAR BACK TO THE DEALER WHERE WE PURCHASED THE CAR, AND WAS TOLD THE SAME THING, ONLY THIS ESTIMATE WAS $2K TO "CLEAN" THE ENGINE. THE SERVICE MANAGER CALLED THE TOYOTA REP ON OUR BEHALF AND WAS DENIED ANY HELP THROUGH THE WARRANTY. IN FILING A REPORT WITH TOYOTA WAS TOLD MY NEXT STEP WAS ARBITRATION - "THE PAPERWORK IS IN YOUR WARRANTY BOOK". I HAD TO HAVE THE ENGINE CLEANED AT MY OWN EXPENSE.*AK

THERE WAS WHITE SMOKE COMING FROM EXHAUST AT START UP, VEHICLE WAS USING 6-7 QUARTS OF OIL IN A 10 WEEK PERIOD. DEALER DETERMINED THERE WAS SLUDGE BUILD UP IN ENGINE, AND ENGINE NEEDED TO BE REPLACED.*AK *SLC

THE VEHICLE CRANKS BUT DOES NOT START, THE VEHICLE CONSUMES EXCESSIVE OIL DUE TO TO THE ENGINE BEING SLUDGED AND THE RINGS WERE BAD, THE DEALER INFORMED CONSUMER THAT A SHORT BLOCK ASSEMBLY NEEDED TO BE INSTALLED, AND WOULD COULD $6000 BECAUSE THE WARRANTY WAS CONSIDERED TO BE INVALID DUE TO IMPROPER MAINTENANCE.*YH

ADDED OIL AND DROVE VEHICLE FOR A FEW DAYS WITH SIMILAR SYMPTOMS - SMOKE AFTER COLD START OF AFTER BEING PARKED FOR MORE THAN 2 HOURS. ON 7/3/01 BROUGHT THE CAR IN TO DEALER FOR DIAGNOSIS. THE DEALER LOOKED UNDER ONLY ONE CAMSHAFT COVER, FOUND EVIDENCE OF SLUDGE AND - EVEN THOUGH I HAD RECEIPTS AND PROOF OF THREE PRIR OIL & FILTER CHANGES AT 5800, 11000, AND 16595 MILES - DECLARED MY ENGINE WARRANTY NULL & VOID AND MADE NO OTHER ATTEMPT TO DIAGNOSE THE PROBLEM. I AM CURRENTLY TRYING TO GET TOYOATA TO HONOR MY WARRANTY AND TO HAVE ANOTHER DEALER OR MECHANIC DIAGNOSE THE PROBLEM. HOWEVER, RESEARCH ON THE WEB INDICATES THAT TOYOTA IS STONEWALLING MANY CUSTOMER LIKE MYSELF.

TOLD BY TOYOTA THAT SLUDGE IN THE ENGINE IS OUR FAULT DESPITE REGULAR OIL CHANGES. WE DON'T HAVE ALL OUR RECEPTS BUT CHANGED THE OIL AT LEAST 4 TIMES SINCE WE OWNED THE CAR. IMPOSSIBLE TO BELIEVE THAT WE WERE NEGLECTFUL, ESPECIALLY WHEN I AM SEEING SO MANY OTHER CASES WITH THE SAME THING HAPPENING. THERE NEEDS TO BE AN INVESTIGATION HERE SOON. *AK

I TOOK MY NEW TOYOTA SIENNA TO BE REPAIRED BECAUSE IT WAS SMOKING. I WAS TOLD THAT THE ENGINE HAD SLUDGE IN IT AND TOYOTA WAS DENYING ANY WARRANTY CLAIMS. HOW DOES A BRAND NEW ENGINE GET SLUDGE IN IT? THERE ARE LITERALLY HUNDREDS OF SIMILAR INSTANCES REPORTED ON VARIOUS SITES ON THE INTERNET. THE PATTERN IS SIMILAR - LOW MILEAGE TOYOTA VEHCLES (ESPECIALLY SIENNAS) SUDDENLY SMOKING AND HAVING SLUDGE IN THEIR ENGINES, DEPSITE PROPER MAINTENANCE AND REGULAR OIL CHANGES. THERE CLEARLY IS A COVERUP HERE BY TOYOTA. THEY ARE DECLINING WARRANTY CLAIMS RATHER THAN TRYING TO DEAL WITH THE PROBLEM.*AK

WE ARE VERY UNHAPPY WITH THIS VAN AND THE LITTLE SERVICE WE RECEIVE WE WISHED WE NEVER PURCHUSE THIS CAR..... UNSAFE & DEFECTIVE. *AK

NO SUMMARY LISTED FOR ABOVE VEHICLE. *AK

COMPLETE AND PERMANENT TRANSMISSION FAILURE. VEHICLE SUDDENLY AND PERMANENTLY LOST ABILITY TO ACCELERATE/TRANSMISSION DISENGAGED WHILE TRAVELING ON INTERSTATE AT 65MPH. BARELY COASTED TO SIDE OF ROAD WHILE TRYING TO AVOID TRAFFIC BEARING DOWN ON US (TWO ADULTS AND THREE SMALL CHILDREN). WE HAVE NOW DISCOVERED THAT THIS DEFECT WITH SIENNAS, WAS KNOWN AS EARLY AS JUNE 2000. THIS DEFECT USUALLY CAUSES COMPLETE TRANSMISSION FAILURE DURING SUSTAINED HIGHWAY SPEEDS. TOYOTA WAS NEGLIGENT IN NOT WARNING OWNERS OF THIS EXTREMELY HAZARDOUS DEFECT. OUR VEHICLE IS NOW ABOUT 300 MILES FROM OUR HOME, WITH NO FIX CURRENTLY AVAILABLE FROM TOYOTA. *AK

HAVE BEEN TOLD I HAVE SLUDGE BUILD UP IN MY ENGINE DUE TO LACK OF MAINTANANCE. I HAVE RECEIPTS FOR 3 OIL CHANGES IN THE FIRST 19000 MILES, BUT THEY THEN TELL ME IT MUST HAVE BEEN INFERIOR OIL. HAVE FOUND THIS TO BE PROBLEM WITH PEOPLE NATION WIDE, AND TOYOTA WILL NOT STAND BEHIND ITS WARRANTY. THERE IS NO WAY THAT THIS PROBLEM HAS BEEN CAUSED SOLELY DUE TO A LACK OF MAINTANANCE TO ALL THE PEOPLE HAVING THE SAME PROBLEM. TOYOTA WANTS TO REBUILD THE ENGINE ON A ONE YEAR OLD VAN WITH 19000 MILES FOR $2200, THOUGH IT WAS PROPERLY MAINTAINED. WILL NOT ACCEPT RECEIPTS FOR SERVICE DONE AS PROOF OF MAINTANANCE. WHAT ELSE ARE WE SUPPOSED TO HAVE TO ENSURE PROOF?*AK

THE VEHICLE WAS ONLY PROVIDED WITH A HOLE IN THE FRAME FOR A TETHER STRAP ON THE LEFT CENTER ISLE SEAT, THE DEALER REFUSES TO DRILL A HOLE IN THE FRAME SO THE HARDWARE CAN BE INSTALLED FOR ANOTHER STRAP FOR HER OTHER CHILD. NLM
