2000 TOYOTA SIENNA Engine And Engine Coolingenginegasoline Problems

AT 107,000 MILES WHILE DRIVING THE MOTOR JUST CUT OFF. THEN WOULD NOT START. I ALWAYS HAVE CHANGED THE OIL AT EVERY 3000 MILES. NOW MY MECHANIC SAYS THAT THE CAMSHAFT BROKE. THERE CAN BE NO OTHER ANSWER THAN THAT THIS ENGINE WAS A SLUDGE DEFECTIVE MOTOR FROM THE MANUFACTURER. *AK

THIS 2000 SIENNA IS A LEMON. AT 50 MILES THE TORQUE CONVERTER NEEDED TO BE REPLACED. AT 100 MILES I NOTICED THAT THE VAN PULLS TO THE LEFT AT HIGHWAY SPEEDS OF 65 TO 70 MPH. AT 28,000 MILES THE FRONT TIRES FIRESTONE WERE ALL CHEWED UP BELTS SHOWING EVEN THOUGH WE HAD 3 ALIGNMENTS DONE IN LESS THAN A YEAR. THE AUTOMATIC SIDE PASSENGER DOOR GOT STUCK AND WOULD NOT CLOSE, DEALER REPLACED DOOR COMPUTER, AT 15,000MILES PAINT WAS CHIPPING OFF THE DOOR HANDLES AND A SHORT TIME LATER PAINT WAS CHIPPING OFF THE FRONT HOOD AS WELL. AT AROUND 20K THE REMOTE KEY/ALARM STARTED BLOWING FUSES, IT'S BEEN BACK 4 TIME TO GET FIXED W/ NOTHING DONE TO FIX IT. THIS IS THE CIRCUT THAT HAS THE ALARM, CLOCK AND DOME LIGHT. FROM THE VERY BEGINING THE TRANS. SOMETIMES WOULD SHIFT EITHER HARD OR W/ A DELY BETWEEN...

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

OUR SIENNA WAS DIAGNOSED WITH SLUDGE BUILDUP IN MAY 2000. WE WERE TOLD IT WAS NECESSARY TO REPLACE THE ENGINE AS EVENTUALLY WE WILL ENCOUNTER ENGINE FAILURE AT SOME POINT. TOYOTA REFUSES TO TAKE RESPONSIBLITY OF THIS MATTER AND CONTINUALLY BLAMES THE OWNERS FOR LACK OF MAINTANENCE. THERE HAVE BEEN OTHER OWNERS WHO HAVE ENCOUNTERED ENGINE FAILURE WHILE DRIVING. WE ARE FORTUNATE TO NOT HAVE HAD THAT. HOWEVER, WE HAVE NO PEACE OF MIND IN DRIVING THIS VEHICLE EVERY DAY, WITH OUR CHILDREN MIND YOU, AND KNOWING WE COULD HAVE ENGINE FAILURE AT ANY TIME. IT IS VERY IMPORTANT THAT AN INVESTIGATION INTO THIS MATTER BE DONE. IT IS OBVIOUS THERE IS A PROBLEM AS TOYOTA HAS HAD OVER 3000 COMPLAINTS SUCH AS OURS. IT IS ONLY A MATTER OF TIME BEFORE SOMEONE IS INJURED OR KILLED AS A RESULT OF TOYOTAS NEGLIGENCE IN THIS MATTER. IS THERE A STIPULATION...

SLUDGE PROBLEM STARTED AT 11111 MILES - ALSO TIRES NEEDED REALIGNMENT AND REPLACEMENT AT ONLY 13115 MILES. THE VAN BLOWS BLUE SMOKE UPON STARTUP. WE HAVE BEEN BLAMED FOR THE SLUDGE PROBLEM. WE HAVE RECEIPTS FOR OIL CHANGES AND HAVE DONE SOME OURSELVES. NOW WE ARE TOLD, BY THE SERVICE DPT. THAT WE HAVE TO CHANGE OUR OIL EVERY 1000 MILES AND CHECK THE OIL EVERY TWO DAYS. BEEN DOING A LOT OF READING ON THIS, AND HAVE TALKED TO OTHERS - THIS IS A DEFECT IN THE SIENNA AND OTHER CARS, LEXUS BEING ONE. WAS TOLD THE ENGINE WOULD SEIZE EVENTUALLY AND I WOULD HAVE TO PUT OUT $5000 - $8000 FOR A NEW ONE. THIS ISN'T COVERED UNDER WARRANTY EITHER.*AK

ENGINE SLUDGED AT 29,080 MILES . ALL OIL CHANGES WERE PERFORMED AS REQUIRED PER WARRANTY MAINTENANCE AGREEMENT. AN ENTIRE ENGINE OVERHAUL IS NOW REQUIRED.*AK

A KNOCKING SOUND CAN BE HEARD COMING FROM ENGINE COMPARTMENT. DEALER HAS BEEN CONTACTED, PLEASE PROVIDE FURTHER DETAILS.*AK

NO SUMMARY LISTED FOR ABOVE VEHICLE. *AK

ANOTHER SIENNA SLUDGE VICTIM. TOYOTA ANSWERS REHEARSED. DID NOT EVEN QUESTION OWNER ABOUT MAINTENANCE HISTORY; THEREFORE, OBVIOUSLY IRRELEVANT TO THEM. CONTACTING ATTORNEY TO INQUIRE ABOUT CLASS ACTION LAWSUIT.NO SAFETY DEFECT LISTED IN SUMMARY. *AK

I BELIEVE ENGINE SLUDGE COMPLAINTS ARE FICTICIOUS.*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...

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

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

THE ENGINE PRODUCE CLOUDS OF GREY/WHITE SMOKE FOR 5 TO 10 SECONDS AFTER A COLD START UP. UPON CHECKING, FOUND THE ENGINE OIL 1.5 TO 2 QUARTS LOW. 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.

UPON STARTING UP AND NORMAL OPERATION OF VEHICLE, SMOKE WILL COME FROM EXHAUST. DEALERSHIP EXAMINED VEHICLE, AND DETERMINED THERE WAS OIL ALL OVER AND THROUGHOUT ENGINE, CAUSING SMOKE. FACTORY REPRESENTATIVE VOIDED WARRANTY, AND INFORMED CONSUMER THAT REPAIRS WERE AT HER EXPENSE, APPROXIMATELY $5000.00. *AK *SLC

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

ENGINE HAD SLUDGE BUILD UP THAT CLOGGED ENGINE AND CAUSED IT TO FAIL. SMOKE WAS COMING OUT OF EXHAUST. NOTHING LIT UP ON DASHBOARD, INDICATING A PROBLEM. CONSUEMR WENT ON A 300 MILE TRIP AND HAD TO ADD 21/2 QUARTS OF OIL. DEALER STATED THE ONLY WAY IT COULD HAVE GOTTEN LIKE THAT WAS BY NOT HAVING OIL CHANGES. CONSUMER HAS RECEIPTS FOR OIL ADDED TO VEHICLE. *AK

WHILE DRIVING ENGINE JUST ALL OF A SUDDEN LOST POWER AND VEHICLE STARTED TO SLOW DOWN IN THE MIDDLE OF TRAFFIC, POSSIBLE ENGINE OR ELECTRICAL MALFUNCTION. *JB

TRANSMISSION WENT OUT AT 75 MPH/TACHOMETER WENT TO ZERO, AND ENGINE KEPT RUNNING. DEALER INFORMED CONSUMER THAT SHE WAS # 49 ON WAITING LIST FOR A TRANSMISSION WHICH WAS ON BACK ORDER. *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

WITH LESS THAN 15,000 MILES ON MY VAN, THICK GREY SMOKE BEGAN POURING OUT OF THE BACK AT STARTUP. I TOOK IT IN TO HAVE THE OIL CHANGED (NOT THE DEALER). IT WAS SUGGESTED THAT I TAKE THE CAR TO THE DEALER, ESPECIALLY IF IT LOST OIL (WHICH IT DID). THE DEALER FOUND EXCESSIVE SLUDGE BUILD UP. THEY SAID THEY HAD TO CLEAN SLUDGE FROM THE CYLINDER HEADS AND CAMSHAFTS, AND REPLACE THE VALVE COVERS, STEM SEALS AND RELATED GASKETS AND THE R&R ENGINE OIL PAN. THEY ALSO SAID THEY CLEANED THE SLUDGE FROM THE PAN OIL PUMP AND PICK UP SCREEN, AND THE CAM CAPS WERE SCORED DUE TO LACK OF OIL LUBRICATION. THE ONSITE SERVICE MANAGER (WHO SUPPOSEDLY SPOKE TO THE REGIONAL SERVICE MANAGER) SAID THE SLUDGE BUILD UP WAS OUR FAULT AND REFUSED TO HONOR THE WARRANTY. WE PAID $2670.82 FOR THE REPAIRS. I'VE HAD THE CAR...

THE CHECK ENGINE LIGHT COMING ON SEEMS TO BE A COMMON PROBLEM IN SIENNAS MANUFACTURED IN JUNE/JULY 2000. IT HAS TAKEN SEVERAL WEEKS FOR THE PART TO COME IN. I AM TOLD A TRANSMISSION SOLENOID NEEDS TO BE REPLACED, BUT THEY'RE REALLY NOT SURE. TOYOTA SERVICE AND DEALERSHIP RESPONSE HAS BEEN POOR.

WE HAVE TO WAIT FOR THE PART(S) BECAUSE EVERY SIENNA HAS THE SAME PROBLEM.

WHILE HAVING CAM SEAL/VALVE SEAL REPLACED DUE TO AN OIL LEAK, MECHANIC NOTICED RIGHT FRONT PASSENGER TIRE HAD A BUBBLE AND WAS REPLACED BY FIRESTONE, CONSUMER STATES VEHICLE IS GOING BACK FOR A 3RD TIME FOR THE OIL LEAK. *SLC

SEVERAL T/C DEFECTS ON THE 2000 TOYOTA SIENNAS... WHY ARENT THEY NOT BEING RECALLED BY THE MANUFACTURER?
