1999 Toyota Sienna Engine

VEHICLE STALLED WHILE DRIVING. DRIVER WAS ABLE TO PULL OVER, AND TRIED TO RESTART VEHICLE BUT WAS UNABLE TO DO SO. AFTERWARDS, DRIVER HAD THE VEHICLE TOWED TO THE DEALER, BUT MECHANIC COULD NOT DUPLICATE THE PROBLEM.*AK

1999 TOYOTA SIENNA ENGINE FROZE UP UNEXPECTEDLY. WAS ADVISED IT WAS POSSIBLY A SLUDGE PROBLEM. THIS VEHICLE WAS PURCHASED - USED - IN 2002 FROM A LOCAL DEALER WHO WILL NOT ACCEPT ANY RESPONSIBILITY FOR THE ESTIMATED $6850.00 ENGINE REPLACEMENT COST, EVEN THOUGH TOYOTA CHANGED THE ENGINE WARRANTY TO 8 YEARS/UNLIMITED MILEAGE.*JB

MY WIFE WAS DRIVING ON THE FLORIDA TURNPIKE WITH OUR SONS (AGES 3 AND 1) IN THE VEHICLE. THE ENGINE LIGHT CAME ON AND THE ENGINE DIED. SHE COASTED OVER TO THE SIDE OF THE ROAD. SHE STAYED IN VEHICLE AND KEPT THE BOYS IN THEIR CAR SEATS AS SHE WAS ALONG A MAJOR HIGHWAY. A ROAD SIDE ASSISTANCE VEHICLE PULLED UP BEHIND HER WITHIN A MINUTE OR TWO. HE ASKED MY WIFE WHAT THE PROBLEM WAS. SHE TOLD HIM AND HE ASKED HER TO POP THE HOOD. SHE DID. HE OPENED IT AND FLAMES CAME OUT OF THE ENGINE COMPARTMENT. NEITHER HE NOR MY WIFE KNEW OR SUSPECTED A FIRE. NO FLAMES. NO SMOKE. NO SMELL. NO HEAT. HE YELLED TO MY WIFE TO GET HERSELF AND THE KIDS OUT OF THE CAR. SHE DID AND THEY WERE ALL UNHARMED. HE PUT THE FIRE OUT WITH A FIRE EXTINGUISHER. OBVIOUSLY, MY WIFE AND CHILDREN PROBABLY WOULD HAVE BEEN KILLED HAD THAT ROAD SIDE ASSISTANT NOT BEEN THERE. FL HIGHWAY PATROL ARRIVED. THE FHP OFFICER FILED INCIDENT REPORT # FHPK05OFF042549. I HAD THE VEHICLE TOWED TO WHERE I BOUGHT IT, TOYOTA OF ORLANDO (3800 W. COLONIAL DRIVE ORLANDO, FL 32808 407-298-4500) I VIDEO TAPED THE BURNED ENGINE AND THE VEHICLE FROM HEAD TO TOE AND WILL BE HAPPY TO SUBMIT A COPY TO YOU. I WAS CALLED BY A MR. MANNY COLON OF TOYOTA OF ORLANDO. HE EXPLAINED TO ME THAT SLUDGE BUILD UP WAS FOUND AND SAID THAT WAS PROBABLY THE CAUSE OF THE FIRE. I HAVE RECORDS (WITH A DIFFERENT SHOP-GOODYEAR) SHOWING THAT THE OIL WAS CHANGED REGULARLY AND NOT TERRIBLY LONG AGO. THERE SEEMS TO BE AN EXTREMELY WELL DOCUMENTED (AND ACKNOWLEDGED BY TOYOTA) SLUDGE PROBLEM WITH TOYOTA'S - INCLUDING THE 99 SIENNA. I HAVE FOUND MANY ARTICLES ON THE INTERNET AND I AM COLLECTING THEM. I WAS NEVER INFORMED OF THIS ISSUE BY ANYONE. IF THIS ISSUE CAN CAUSE AN ENGINE FIRE, WHY ARE THESE VEHICLES BEING ALLOWED ON THE ROAD WITH FAMILIES AND CHILDREN RIDING IN THEM? MY ENTIRE FAMILY ALMOST DIED YESTERDAY. PLEASE INVESTIGATE THIS. I DON'T WANT OTHERS TO DIE IF IT CAN BE AVOIDED. *NM

THE CONSUMER STATES VEHICLE IS BURNING EXCESSIVE OIL. *AK THE CONSUMER STATED THAT OIL WAS IN THE PAN. THE CONSUMER STATED THAT OTHER OWNERS HAVE THE SAME PROBLEM. *TC

OIL SLUDGE (GELLING) DEVELOPS IN ENGINE RESULTING IN THE NECESSITY TO REPLACE THE ENGINE AT GREAT COST. TOYOTA STATES THAT THEY WILL PAY FOR THE REPAIRS IF ALL REQUIRED MAINTENANCE HAS BEEN PERFORMED, BUT THEY HAVE REFUSED TO DO SO AND HAVE REFUSED TO LET US SPEAK WITH ANYONE WITH THE AUTHORITY TO HONOR THEIR WARRANTY. *JB

MY VAN HAD FIRST ENGINE OIL SLUDGE PROBLEM AT 32782 MILES IN MARCH 2003. FINALLY TOYOTA PAID THE REPAIR COST AFTER MANY PHONE CALLS. ONE YEAR LATER, ON JULY 5,2004, I FOUND THAT THERE IS NO ENGINE OIL LEFT AGAIN DURING THE MIDDLE OF OUR FAMILY VACATION TRIP (AT 46000 MILES). AND BLUE SMOKE COMES OUT FROM EXHAUST PIPE AGAIN. TOYOTA COULDN'T FIX THE PROBLEM BY CLEARING CHANGING SOME PARTS. I REQUEST TOYOTA REPLACE THE DEFECT ENGINE.*AK

1999 TOYOTA SIENNA IS SITTING IN DRIVEWAY FOR PAST 2 MONTHS WITH SEIZED ENGINE DUE TO THIS "OIL SLUDGING" PROBLEM. COST TO REPAIR OVER 6000 FROM DEALER. CERTIFIED MAIL SENT 2/18/04 TO TOYOTA MOTOR SALES IN TORRANCE, CA., WITH COPY OF MAINTENANCE RECORDS SHOWING OIL FILTER & OIL CHANGES.*AK

LIGHT BLUE SMOKE FROM TAIL PIPE .OIL CAP DARK BROWN

MY 1999 TOYOTA SIENNA'S ENGINE SUDDENLY FROZE UP WITH SLIGHTLY LESS THAN 72,000 MILES ON IT. THE ENGINE IS TOTALLY GONE WITH ESTIMATES CURRENTLY IN THE NEIGHBORHOOD OF $8,000. THIS VEHICLE HAS BEEN MAINTAINED AS STATED IN THE OWNERS MANUAL. THE COMPLAINT IS THAT TOYOTA KNOWS THERE IS A PROBLEM WITH SIENNA'S AND HAS FAILED TO DO ANYTHING ABOUT NOTIFYING OWNERS THAT OIL CHANGES NEED TO BE AT 3000 MILE INTERVALS AND THAT VALVES NEED TO BE CHECKED VERY REGULARLY. SINCE SLUDGE BUILD-UP IS OBVIOUSLY OCCURRING IN THEIR VEHICLES, SOMETHING NEEDS TO BE DONE TO PROTECT THE CONSUMER. *LA

OIL BURNS AT HIGH HEAT WHICH CAUSES THE OIL TO DEVELOP INTO A GEL. AS A RESULT, THE ENGINE FAILS PREMATURELY. *AK

ENGINE OF 1999 TOYOTA SIENNA (VAN) HAD SLUDGED ENGINE OIL IN JULY 2002, DEALER REBUILT ENGINE. IN NOVEMBER 2003, OIL PUMP FAILED ON SAME VEHICLE. DEALER CONTENDS THE FAILURE OF THE OIL PUMP IS NOT RELATED TO THE ENGINE OIL GELLING/BECOMING SLUDGE. SINCE ENGINE WAS REBUILT, OWNER HAS CHANGED OIL EVERY 3,000 MILES AND HAS RECEIPTS TO PROVE IT. *LA

THE CONSUMER BELIEVED TOYOTA WAS NOT HONORING THE CUSTOMER SUPPORT PROGRAM AS REPORTED BY OWNERS, IN REGARDS TO OIL SLUDGE BUILD UP IN ENGINES. *AK *JB UPDATED 05/04/10.*JB

WHILE DRIVING VEHICLE CONSUMER STATES" NOTICED BLUE SMOKE COMING FROM EXHAUST. TOOK TO DEALER AND THEY PERFORMED A ENGINE OVERHAUL. CONSUMER FEELS ENGINE MAY SEIZE UP. PLEASE PROVIDE ANY FURTHER INFORMATION. TS

THE ENGINE SEIZED WHILE DRIVING HOME ON INTERSTATE 75. WE HAD JUST HAD THE OIL CHANGED BEFORE LEAVING ON VACATION. TOYOTA SAID THAT WE DID NOT SERVICE THE VEHICLE PROPERLY DESPITE OUR HAVING PROVIDED PROOF OF OIL CHANGES. TOYOTA WOULD NOT COVER REPAIRS OF $6200. THE FINANCE COMPANY REPOSESSED THE CAR BECAUSE WE COULD NOT AFFORD TO PAY FOR IT TO BE FIXED.*AK

SIENNA ENGINE SEIZED WHILE TRAVELING ON INTERSTATE 75. WE HAD JUST HAD THE OIL CHANGED PRIOR TO LEAVING TO GO ON VACATION. TOYOTA BLAMED US FOR THE PROBLEM: SAID IT WAS DUE TO LACK OF VEHICLE MAINTENANCE DESPITE OUR FURNISHING PROOF OF REGULAR OIL CHANGES. COST OF REPLACEMENT ENGINE WAS ESTIMATED @ APPROX. $5000. WE COULD NOT PAY FOR THE REPAIRS AND TOYOTA WOULD NOT COVER THEM. VAN WAS REPOSESSED BY OUR FINANCE COMPANY. WE HAD TO TAKE OUT A HOME EQUITY LOAN TO PAY OFF THE BALANCE OF $6,000 OWED TO OUR FINANCE COMPANY.*AK

WE FEEL THAT KINGSPORT TOYOTA (KINGSPORT TENNESSEE) DID NOT WANT TO BE BOTHERED WITH THIS ISSUE DUE TO THE FACT THAT PROBLEMS WERE STARTING TO ARISE AND CONSUMERS WERE QUESTIONING TOYOTA ABOUT SLUDGE BUILD UP IN THE ENGINES.*AK

AT 44,000 MILES WE HAD TO HAVE OUR CYLINDER REGROUND AND THIS SHOULDN'T HAPPEN. WE CHANGED OIL EVERY 5,000 MILES LIKE THE OWNER'S MANUAL SAID. THIS IS RIDICULOUS THAT IT SHOULD HAPPEN AT ALL! THIS IS A FAULTY ENGINE. WE SHOULD HAVE RECIEVED A NEW ENGINE UNDER WARRANTY, NOT HAD THE DAMNED CYLINDERS REGROUND. NOW, THEY'RE TELLING US TO CHANGE OIL EVERY 3,000 MILES! WHAT IS GOING ON? WE'VE OWNED TOYOTAS SINCE 1969 AND NEVER HAD A PROBLEM WITH THEM--AND CERTAINLY NOT SOMETHING LIKE THIS. THIS IS POOR QUALITY OF THE ENGINE AND TOYOTA SHOULD GIVE US A NEW AND IMPROVED ENGINE TO REPLACE THIS ONE.*AK

ALL THE OIL PORTS WERE COMPLETELY PLUGED AND THERE WAS NO WARNING EITHER TIME. IT IS A WONDER THAT WITH ALL THE PORTS PLUGED AND THE ENGINE BOTH TIMES NOT GETTING ANY OIL TO THE UPPER ENGINE THAT IT DID N OT FREESE UP AND CAUSE A SERIOUS ACCADENT. *AK

DIAGNOSED AS SLUDGE IN THE ENGINE DUE TO "OWNER NEGLIGENCE"; OWNER HAS PROOF OF REGULAR OIL CHANGES AND MAINTENANCE; OWNER ACCUSED OF "NEVER CHANGING THE OIL"--NOT TRUE; TOYOTA IS AWARE OF THE PROBLEM IN THEIR SIENNAS AND AVALONS, SAYS WE ARE INELIGIBLE FOR "ASSISTANCE" BECAUSE WE ARE OUTSIDE OF THE 60000 DRIVE TRAIN WARRANTY; PROPERLY MAINTAINED ENGINES DON'T SEIZE UP AT 64K MILES!! WE ARE OUTRAGED!!*AK

DRIVING TO PHOENIX, ENGINE WENT IN OGDEN UTAH, SAID SLUDGE IN ENGINE, ALTHOUGH HAVE OIL CHANGE RECEIPTS, TOYOTA UNINTERESTED. CLAIMS IMPROPER MAINTENANCE SO NO WARRANTY COVERAGE. *AK

TITAN CHECKUP ENGINE ANALYSIS OIL SAMPLE RESULTS REVEALED EXCESSIVE FUEL IN THE ENGINE'S OIL AFTER 6700 MILES OF DRIVING. OIL NOTED TO BE TOO THIN AND SOME LEAD FROM BEARING SCUFFING NOTED. SILICON ALSO PRESENT IN TWO OIL ANALYSIS SAMPLES TO DATE. POSSIBLE FIRE HAZARD WITH REDUCED FLASH POINT. FULL INVESTIGATION NEEDED ON 1998-2001 MODEL SIENNAS IN CONJUNCTION WITH CURRENT ENGINE FIRE INVESTIGATION ON THE 2002 MODEL. *AIK

THE ENGINES IN 1999 SIENNA VANS ARE POSSIBLY HAVING EARLY FAILURE OF THE CRANKECASE VENTILATION SYSTEM THAT CAUSES OIL TO SLUDGE UP AND THE ENGINE BEGINS TO BURN OIL AT A VERY EARLY AGE. I RECENTLY DE-SLUDGED MY VAN'S ENGINE AND NOTED THAT THE CRANKECASE VENT BAFFLES ARE VERY NARROW AND HAD LIKLEY BEEN STOPPED UP FOR A LONG TIME. FROM THE AMOUNT OF POSTINGS ON THE INTERNET ABOUT THIS PROBLEM THIS IS NOT AN ISOLATED PROBLEM WITH THIS MODEL. *AK

CAR USING OIL SINCE 20000MI. 9/01 DEALER FOUND SLUDGE IN ENGINE AND CLAIMED IT WAS MY FAULT AND WOULD NOT REPAIR UNDER WARRANTY. *AK
