1999 TOYOTA SIENNA Engine And Engine Coolingengine Problems

I AM REPORTING ANOTHER TOYOTA STICKY ACCELERATOR PEDAL. OUR 1999 SIENNA MINIVAN HAS HAD 3 INCIDENTS OF STUCK ACCELERATOR, THE MOST RECENT WAS JAN. 21, 2010. I BELIEVE IT HAS BECOME "STUCK" BETWEEN 40 AND 45MPH. OTHER INCIDENTS WERE IN SUMMER (CANNOT REMEMBER DATE) AND OCTOBER 2009. THE 1ST INCIDENT WAS BRIEF AND CORRECTED QUICKLY BY PUSHING DOWN ON THE PEDAL TO "FREE IT", THE 2ND INCIDENT REQUIRED BRAKING AND PUTTING THE CAR IN NEUTRAL AND SHOVING THE PEDAL WITH MY FOOT TO THE LEFT AND RIGHT TO FREE IT UP. I WAS ABLE TO DRIVE THE CAR TO THE SHOULDER, TURNED THE CAR OFF AND THEN THE PEDAL SEEMED TO WORK OK, ALTHOUGH A BIT SLUGGISH RESPONSE. OUR MECHANIC FIXED THE THROTTLE BODY AND THE CAR HAS NOT HAD ANOTHER INCIDENT UNTIL LAST WEEK. THE MOST RECENT INCIDENT WAS MORE HARROWING IN THAT THERE WAS NOT MUCH ROOM TO...

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....

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 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

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
