ENGINE

I OWN A 2006 TOYOTA SIENNA LE WITH ONLY 26500 MILES ON IT. I WAS DRIVING MY CAR ON THE HIGHWAY DOING 45 MILES PER HOUR ON A DRY PAVEMENT ON TUESDAY 09/03/2019 AROUND 6:40 PM AND AT A SUDDEN MOMENT THE VSC LIGHT STARTED FLASHING, WARNING SOUND CAME ON, THE CAR APPLIED THE BRAKES ON ITS OWN HARD UNTIL IT FULLY STOPPED, AND THE ENGINE SHUT OFF BY ITSELF, WHICH ALMOST GOT ME INTO AN ACCIDENT. I CONTACTED TOYOTA AND THEY TOLD ME THAT I HAVE TO PAY FOR THE DEALER TO GET THE CAR DIAGNOSED FOR THIS SAFETY ISSUE, THEY TRANSFERRED ME TO HUDSON TOYOTA AND THEY CONFIRMED THAT I HAVE TO PAY FOR IT DESPITE THAT I HAD MY CAR TO THE DEALER RECENTLY FOR TWO RECALLS AND THEY CHECKED THE CAR AND GAVE ME A REPORT THAT EVERYTHING IN THE CAR WAS GOOD. I HAVE LOOKED ONLINE AND I FOUND A LOT OF TOYOTA SIENNA OWNERS FROM THIS MODEL COMPLAINING ABOUT IT AND YOUTUBE VIDEOS DOCUMENTING IT, THIS LINK SHOWS A TOYOTA SIENNA OWNER DOCUMENTING ON VIDEO THE SAME PROBLEM (HTTPS://YOUTU.BE/SY9A8SHJ0XG) WHICH HAPPENED WITH HIM 20 TIMES IN THE COURSE OF 90 MINUETS AND THE DEALER COULD NOT FIND WHAT WAS WRONG WITH HIS CAR. THIS ISSUE SHOULD BE FIXED UNDER A RECALL BY TOYOTA BECAUSE THE CAR SHOULD NOT BE ABLE TO APPLY THE BRAKE ON ITS OWN RANDOMLY ON THE HIGHWAY.

CHECK ENGINE LIGHT, VSC LIGHT, TRACTION CONTROL LIGHT. ALL 3 LIGHTS CAME ON AT SAME TIME. THEY SAY IT'S THE GAS CAP, IT'S NOT THE GAS CAP, THEY SAY TO RESET IT, THAT DOESN'T WORK. I WAS DRIVING HOME, NOTHING HAPPENED, THE LIGHTS JUST CAME ON. NO WARNING SOUND, NOTHING TO INDICATE THERE WAS A PROBLEM, MY CAR SEEMS TO DRIVE JUST FINE, BUT THE LIGHTS WON'T GO OFF, AND I HAVE 3 KIDS THAT I TAKE AND PICK UP FROM SCHOOL

ENGINE

TODAY I NOTICED A SMELL BUT THOUGHT IT WAS FROM THE ROAD CONSTRUCTION. LATER I NOTICED SOME LIQUID ON THE GROUND UNDER MY CAR. LATER I STARTED TO DRIVE AND HEARD A TERRIBLE NOISE. I CHECKED ALL MY GAUGES AND NOTHING LOOKED WRONG BUT THE NOISE FREAKED ME OUT. I IMMEDIATELY TURNED AROUND AND WENT HOME. FORTUNATELY I HAD ONLY GONE A LITTLE WAYS DOWN THE STREET. WHILE I DRIVE MY OIL LIGHT FLICKERED ON THEN OFF. ONCE HOME MY HUSBAND CHECKED UNDER THE HOOD. WHEN HE TURNED THE CAR ON, OIL WAS SQUIRTING FROM A HOSE EVERYWHERE. HE CHECKED UNDER THE CAR AND OIL WAS ALL OVER THE BOTTOM OF THE CAR. THERE WAS NO MORE OIL WHEN HE CHECKED THE OIL STICK.

ENGINE AND ENGINE COOLING

1) AUGUST 2013 DURING AN OIL CHANGE THE DEALER TECHNICIAN NOTIFIED ME THE STEERING RACK NEEDED REPLACING DUE TO OIL LEAKS FROM THE RACK AND PINION ($1000 REPAIRS). 2) SEPTEMBER 2014 ASKED DEALER TO CHECK AIR CONDITIONING AC RIGHT CENTER CONSOLE BLOWER. AFTER RECHARGING THE SYSTEM WITH DYE, FOUND THE AC LINES TO THE REAR CABIN CORRODED UNDER THE WHEEL WELLS -- RECOMMENDED $1500 TO REPLACE ENTIRE LINES (I DECLINED PENDING FURTHER INSPECTION SUMMER 2015). 3) FEBRUARY 2015 NOTICED RIGHT SIDE POWER SLIDING DOOR STOPPED WORKING ELECTRONICALLY, WITH KEY FOB, INTERIOR SWITCHES, ETC., AND WOULD ONLY WORK WHEN PULLING OPEN/CLOSING MANUALLY BY HAND. ACTUATORS STILL WORKED TO "LOCK" THE DOOR DURING THE LAST INCH CLOSING/OPENING. NOTICED BLACK CABLE SHEATHING FRAYED AND BARE IN SPOTS, SHOWING STEEL CABLE INSIDE, BUT CABLE STILL INTACT. FOUND ONLINE FORUMS STATING MANY HAVING SIMILAR ISSUES. LOCATED MY EXTENSION TO WARRANTY ENHANCEMENT NOTICE FROM TOYOTA MAILING STATING "CERTAIN 2004-2007 MODEL YEAR SIENNA REAR SLIDING DOOR LATCH ASSEMBLIES AND POWER SLIDING DOOR CABLE ASSEMBLIES" MAY BE COVERED (UP TO 120K OR 9 YEARS FROM ORIGINAL DATE OF PURCHASE, WHICHEVER CAME FIRST), VIA THE TOYOTA CUSTOMER SUPPORT PROGRAM. HOWEVER, THIS "ENHANCEMENT" DOES NOT COVER DOOR MOTOR ASSEMBLY FAILURES, WHICH MY DEALER TECHNICIAN IDENTIFIED AS THE PROBABLE MAIN CAUSE OF THE DOOR NOT WORKING PROPERLY (AFTER HAVING REMOVED PART OF THE DOOR FOR INSPECTION). I DECLINED THE $1000 LABOR + $1200 PARTS ($2200 TOTAL) MOTOR, BUT ACCEPTED THE FREE CABLE ASSEMBLY WARRANTY COVERAGE. AM NOW USING THE DOOR IN MANUAL MODE ONLY. MY CONCERNS: THESE PARTS ARE WEARING OUT PREMATURELY UNDER NORMAL USE/WEAR AND TEAR.

ENGINE AND ENGINE COOLING:ENGINE

ISSUE: MY 2006 TOYOTA SIENNA'S VENTILATION SYSTEM HEATS UP EVEN IF SETTING AT COLD LEVEL. IT CAUSED THE INTERIOR OF THE VAN TO HEAT UP UNCONTROLLABLY AND COULD CAUSE HEAT EXHAUSTION DURING HOT SUMMER DAYS. THE UNWANTED HEAT WAS TRACED FROM HEAT AT THE ENGINE COMPARTMENT ENTER THE PASSENGER CABIN THROUGH THE VENTILATION SYSTEM. DUE TO INSUFFICIENT INSULATED AREA AT THE ENGINE COMPARTMENT TO THE PASSENGER COMPARTMENT. IT IS EXTREMELY DANGEROUS FOR YOUNG CHILDREN IN THE VEHICLE DURING HOT SUMMER TIME. WE NOTICED THE ISSUE DURING ONE OF OUR SUMMER VACATION IN 2007. WE WERE STUCK IN HEAVY TRAFFIC FOR MORE THAN 15 MINUTES. OUTSIDE TEMPERATURE WAS AT A COMFORTABLE 75 DEGREE, BUT THE INTERIOR OF VEHICLE FEELS LIKE 90 DEGREE. THE AIR COMING FROM THE AIR VENT IS HOT. I DID SOME RESEARCH ON THIS ISSUE, IT TURNS OUT THAT TOYOTA FIXED THIS ISSUE ON 2008 AND LATER VEHICLES BY ADDING INSULATION PAD BETWEEN THE ENGINE COMPARTMENT AND VENTILATION SYSTEM. HOWEVER, THE TOYOTA DEALERSHIP REFUSE TO PROVIDE THE FIX TO MY VAN.

ENGINE AND ENGINE COOLING:COOLING SYSTEM

DRIVING MY 2006 TOYOTA SIENNA ON A BUSY FREEWAY WITH THREE CHILDREN AGES 1, 7, & 10 WHEN THE AIR CONDITION COMPRESSOR DECIDED TO SEIZE UP CAUSING THE BELT TO BURN AND EVENTUALLY SNAP. THE BURNING BELT RESULTED IN A LITTLE SMOKE AND A FEARFUL SMELL FILLING THE CABIN. FEARING A FIRE, I WAS FORCED TO PULL OFF THE ROAD PUTTING MYSELF AND MY THREE CHILDREN IN HARMS WAY. AFTER DETERMINING THERE WAS NOT A FIRE, WE CLIMBED BACK IN THE VAN AND CONTINUED ON OUR WAY. AFTER A LITTLE RESEARCH, I'VE LEARNED THE COMPRESSOR PROBLEMS ARE NOT UNCOMMON IN TOYOTA SIENNA. IN MY CASE OUR VEHICLE HAD LESS THAN 45K MILES. SEEMS THERE ARE MANY UNSATISFIED SIENNA OWNERS WHO HAVE EXPERIENCED A SIMILAR PROBLEM, AND TOYOTA SHOULD CONSIDER RECALLING ALL VEHICLES WITH THIS AIR CONDITIONING SYSTEM. I FEEL THIS IS A MAJOR SAFETY CONCERN SINCE THE MINI-VAN IS CONSIDERED A FAMILY VEHICLE.
