LAST SUMMER 3 TIMES DURING HOT DAYS THE BUTTONS ON THE SLIDING DOORS OF MY 2000 TOYOTA SIENNA GOT STUCK. THE DOOR WOULD NOT CLOSE OR COULD NOT BE OPENED DEPENDING ON WHEN THE BUTTON GOT STUCK. THE BUTTON DID UNSTICK AFTER RUNNING THE A/C FOR 20 TO 30 MINUTES. IT IS A HAZARD WITH 4 SMALL CHILDREN NOT TO BE ABLE TO OPEN OR CLOSE THE SLIDING DOORS. AS IT IS GETTING HOT AGAIN, I FEAR THAT IT WILL HAPPEN AGAIN THIS SUMMER.
COSCO MODEL # 02452-WAL MAN ,07-02-2003, THE SEAT COVER BRACKET ATTACHED TO THE SEAT BROKE. CONSUMER NOTIFIED THE MANUFACTURER FOR A REPLACEMENT . WITHIN SIX MONTHS, THE SEAT FELL APART. *AK
THE INSIDE CABLE TO THE DRIVER SIDE REAR DOOR WILL NOT OPEN FROM THE INSIDE. THE 2000 TOYOTA SIENNA VAN HAS 70,000 MILES AND I DO HAVE CHILDREN DRIVING WITH ME. TOYOTA IS WILLING TO PAY HALF THE LABOR COST PLUS PARTS BUT THE PEOPLE I SPEAK TO LAUGH OFF THAT IT IS A SAFETY PROBLEM. I WOULD LIKE TO KNOW IF OTHER COMPLAINTS HAVE BEEN REPORTED WITH THIS PROBLEM? IF SO HOW MANY? OTHER WISE I AM PLEASED WITH THE CAR BUT WILL HAVE SECOND THOUGHTS ABOUT PURCHASING ANOTHER TOYOTA.
TOLD BY WINDWARD TOYOTA HAWAII THAT SLUDGE BUILDUP NECESSITATED ENGINE REPLACEMENT OF 2000 TOYOTA SIENNA VAN W/ 55,000 MILES. TOYOTA REFUSES TO COVER REPAIR WORK UNDER POWER TRAIN WARRANTY W/O YEARLY OIL CHANGE RECEIPTS. FROM AUTOMOTIVE NEWS - CERTIFIED MASTER TECHNICIAN REPAIR SHOP OWNER WHO SEES A DISPROPORTIONATE NUMBER OF THE ENGINES COMING THROUGH HIS REPAIR SHOP ON THE 1999-20000 SIENNAS: LARRY PERRY, AN A.S.E.-CERTIFIED MASTER TECHNICIAN,REPAIR-SHOP OWNER AND HOST OF A RADIO TALK SHOW IN ORLANDO, FLA., SAYS HE HAS DISCOVERED AN APPARENT DESIGN FLAW IN 3.0-LITER V-6S PRODUCED BETWEEN 1999 AND 2001. HE SAYS HE SEES A DISPROPORTIONATE NUMBER OF THE ENGINES COMING THROUGH HIS SHOP ON 1999 AND 2000 SIENNAS. WE BELIEVE TOYOTA REDUCED THE SIZE OF COOLING PASSAGES TO THE CYLINDER HEADS IN THOSE ENGINES IN ORDER TO INCREASE COMBUSTION TEMPERATURES FOR MORE OF A COMPLETE BURN TO REDUCE EXHAUST EMISSIONS, PERRY SAID. EXCESSIVE HEAT MAKES OIL MORE SUSCEPTIBLE TO SLUDGE. PERRY SAYS HE HAS MEASURED CYLINDER-HEAD TEMPERATURES AS HIGH AS 260 DEGREES IN THOSE ENGINES - 30 DEGREES HIGHER THAN IN EARLIER MODELS. PERRY ALSO POINTS OUT THAT THIS ENGINE SERIES USES A LIFTER BUCKET INSTEAD OF A ROCKER ARM TO OPEN AND CLOSE THE VALVES. THE LIFTER SITS IN THE HEAD AND GETS SLUDGE AND DEBRIS COMPACTED UP UNDERNEATH IT. SO WHEN IT GETS COMPACTED BY THE CAMSHAFT, IT'S SQUEEZING OIL INTO THE COMBUSTION CHAMBERS, HE SAID. IN THIS CASE, HE SAID, THE SOLUTION IS TO USE ONLY 100 PERCENT SYNTHETIC
4 of 4 complaints, reproduced as filed.
No unusual pattern of severe incidents in the complaint record.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Most recent recall on file: none. Source: NHTSA Office of Defects Investigation.
