THE ENGINE FAILED WHILE ENTERING THE HIGHWAY. ALL POWER WAS LOST AND VEHICLE HAD TO BE TOWED TO THE LOCAL TOYOTA DEALER. I WAS INFORMED TODAY THAT IN ORDER TO ANALYZE THE PROBLEM THE ENGINE NEEDS TO BE REMOVED AT $140 PER HOUR APPROX. 20 HRS OF LABOR. I HAVE GIVEN THEM PERMISSION TO DO THIS SO I CAN RECEIVE A QUOTE AS TO HOW MUCH TO REPAIR. THIS SIENNA WAS JUST IN FOR 125,000 MILE SERVICE WITH NO KNOWN ISSUES. I DO NOT HAVE ANY TYPE OF DOCUMENTATION AS OF TODAY JUNE 4,2018.

IN MOTION, WHEN I LET UP OFF THE ACCELERATOR TO ASSESS TRAFFIC, SUCH AS AT THE TOP OF AN ON-RAMP OR OTHER MERGING SITUATION, THEN I DECIDE IT IS SAFE TO MERGE, AND I PRESS THE ACCELERATOR, THE VEHICLE STALLS BRIEFLY BEFORE "CATCHING" AND ACCELERATING. THE ENGINE DOESN'T SPUTTER OR CUT OFF, THE VEHICLE JUST SITS STILL AS THOUGH IT ISN'T GETTING GASOLINE. I'VE HAD A FEW CLOSE CALLS WHEN ATTEMPTING TO ACCELERATE AND MERGE INTO TRAFFIC. THIS ISN'T A GEAR DOWN-SHIFT/UP SHIFT TYPE THING...JUST A STALL. IT'S NOT EVERY TIME I SLOW DOWN TO COAST, THEN DECIDE TO ACCELERATE, BUT SPORADICALLY. I'VE HAD THE VAN CHECKED BY THE DEALER AND THEY COULDN'T FIND ANYTHING. I WAS TOLD IT'S A "COMPUTER THING," WITH THE COMPUTER GETTING CONFUSED BECAUSE TO DOESN'T KNOW WHETHER I WANT THE VAN TO COAST TO A STOP OR TO ACCELERATE, AND "THE COMPUTER GETS CONFUSED." I DON'T HAVE SPECIFIC DATES

ABOUT 20 MINUTES AWAY FROM HOME WE HEARD SOME "GROWLING" AND "TICKING" NOISE FROM THE ENGINE. NO INSTRUMENT WARNING LIGHTS CAME ON. AS WE PULLED INTO OUR STEEP DRIVEWAY, THE OIL PRESSURE LIGHT STARTED TO BLINK. WE SHUT THE ENGINE. UPON INSPECTION, THE OIL DIPSTICK APPEARED DRY. I ADDED ABOUT 4 QTS OF OIL, AND STARTED THE ENGINE. IT SOUNDED NORMAL, AND NO WARNING LIGHT WAS DISPLAYED. I BROUGHT THE CAR TO A LEVEL AREA AND CHECKED OIL AGAIN. I ADDED ANOTHER QUART - OIL WAS BETWEEN THE MARKS ON THE DIPSTICK. I NOTICED LIGHT DRIPPING FROM THE FRONT AREA OF THE ENGINE, NEAR THE OIL COOLER. I THEN DROVE THE CAR TO THE AUTO REPAIR SHOP (ABOUT 4 MILES AWAY). ENGINE SOUNDED OK, NO WARNING LIGHTS. NEXT DAY I WAS TOLD THAT THE OIL LINE TO THE OIL COOLER IS LEAKING, AND THERE'S DAMAGE TO THE ENGINE DUE TO RUNNING WITH NO OIL. I ASSUME THAT THE ENGINE OPERATED WITH NO OIL WHEN WE HEARD NOISES - BUT HOW COULD THE OIL LEAK OUT AND RUN THE ENGINE DRY FOR 15 MINUTES *BEFORE* THE LIGHT CAME ON? HOW COMMON IS THE PROBLEM OF THE OIL-COOLER HOSE FAILING? DOES THIS MODEL SHARE THE SAME ENGINE AS THE LEXUS RX350? IF SO - IS THE PROBLEM RELATED (I READ THAT MANY RX350 OWNERS COMPLAINED ABOUT THIS) ?

TOYOTA SIENNA 2010 MINIVAN ENGINE STALLS WHILE DRIVING. WHEN DRIVING ON HIGHWAY OR ON CITY ROADS, ENGINE STALLS AND LOOSES ENGINE POWER FOR A FEW SECONDS (SEEMINGLY HAPPENS WHEN SHIFTING GEARS) WHEN ACCELERATED OR DECELERATED. THE ENGINE BASICALLY STALLS DURING DRIVING AND MAY LEAD TO SUDDEN VEHICLE SLOWNESS IN MIDDLE OF TRAFFIC. THE SUSPECTED PROBLEM ADVISED BY TOYOTA IS WITH TRANSMISSION AND THE ORIGINAL COST ESTIMATE WAS $5100 TO FIX THAT. LATER AFTER DISCUSSING WITH TOYOTA IT WAS LOWERED TO $3800 (APPROX) AND TOYOTA WARRANTY SUPPORT WAS READY TO PAY (ABSORB) $2000 AND $1800 TO BE PAID BY THE CUSTOMER. EVEN AFTER INITIAL REPAIR AND PAYMENT OF ($1800+TAX) $2166 THE VEHICLE STILL HAVE THE SAME SYMPTOMS AND ISSUES. PRESENTLY THE VEHICLE IS UNDER REPAIR WITH THE DEALER (FREMONT TOYOTA, CA). THE VEHICLE USE WAS NORMAL, REGULAR CITY/HIGHWAY USAGE, WELL MAINTAINED SINGLE OWNER. NOTHING HEAVY WAS TOWED AND USED IN ROUGH OR ABNORMAL CONDITIONS. IF POSSIBLE NTSB NEEDS TO: 1. TO LOOK INTO THIS MODEL OF VEHICLE AND SEE IF THERE ARE OTHER REPORTED PROBLEMS WITH SIENNA 2010 ENGINES. 2. TO INVESTIGATE WHY THIS VEHICLE HAVE THIS ISSUE WITHIN 46,847 MILES. 3. CAN MANUFACTURE BILLS THE ENTIRE COST OF REPAIR, SINCE THIS SEEMS A MAJOR DESIGN OR ENGINE ISSUE WITH THIS MODEL OF VEHICLE. 4. ADVISE TO ISSUE A SAFETY NOTICE TO ALL TOYOTA SIENNA 2010 V6 ENGINE MODEL OWNERS SINCE THIS CAN BE DISASTROUS IN MIDDLE OF TRAFFIC AND CAN CAUSE ACCIDENTS/PROBLEMS TO ALL ON THE ROAD. *TR

MY WIFE WAS RETURNING HOME WITH HER 2011 TOYOTA SIENNA VAN. SHE PULLED INTO THE DRIVEWAY, TOOK HER FOOT OF THE GAS AND PUT ON THE BRAKE BUT THE VAN ACCELERATED RIGHT INTO MY 2011 FORD FUSION, CAUSING A LOT OF DAMAGE. I WON'T KNOW EXACTLY HOW MUCH UNTIL THE BODY SHOP CALLS ME TOMORROW. OF COURSE I KNOW THE SIENNA WASN'T EVEN ON TOYOTA'S RECALL, BUT I HAVE SEEN MANY REPORTS OF THE SAME PROBLEM ON LINE. MY WIFE IS NOW AFRAID TO DRIVE THE VEHICLE AND WE DON'T KNOW WHAT TO DO? *TR

SUBJECT: SMOKE FROM NEW 2010 TOYOTA SIENNA CE. I BOUGHT WHAT APPEARED TO BE A NEW 2010 TOYOTA SIENNA FROM DCH BRUNSWICK TOYOTA IN NORTH BRUNSWICK, NEW JERSEY ON MARCH 29, 2010. ITS ODOMETER READ 95 MILES. WE LEFT THE DEALERSHIP AT ABOUT 7:00 PM. MY WIFE DROVE THE CAR AND MY MOTHER, WHO IS SUFFERING FROM SCIATICA AND HAS RECENTLY UNDERGONE AN OPERATION, SAT IN THE PASSENGER SEAT. (IT MUST BE MENTIONED HERE THAT BOTH MY WIFE AND MOTHER HAVE EXTENSIVE EXPERIENCE IN DRIVING CARS THAT GOES BACK AT LEAST TEN YEARS, AND MY WIFE ESPECIALLY IS QUITE FAMILIAR WITH THE BASICS OF CAR MECHANICS.) AT ABOUT 7:30 PM, WHEN MY WIFE TURNED THE HEATER ON, THE ENGINE STARTED MAKING LOUD THUMPING SOUNDS. MY MOTHER NOTICED A GLOW IN THE HOOD. A CONSIDERABLE AMOUNT OF THICK DARK SMOKE STARTED RISING FROM THE HOOD. MY WIFE STOPPED THE CAR IMMEDIATELY AND TURNED THE ENGINE OFF. THINKING THAT THE ENGINE WAS ABOUT TO EXPLODE, THEY LEAPED OUT OF THE CAR AND RAN AWAY TO A SAFE DISTANCE IN THE MUD ON THE SIDE OF THE STREET FEARING FOR THEIR LIVES. THE PHYSICAL AND EMOTIONAL TRAUMA THAT MY MOTHER WAS SUBJECTED TO HAS CAUSED A SUBSTANTIAL INCREASE IN THE BACK PAIN LEADING TO NIGHTMARES AND INSOMNIA. THE SMOKE THAT THE CAR CONTINUED TO EMIT FOR ANOTHER HALF AN HOUR GAVE THE IMPRESSION THAT THE ENGINE COULD EXPLODE ANY TIME. WE CALLED THE DEALERSHIP AND THEY HAD TO TOW THE CAR BACK TO THEIR PLACE. THE DEALERSHIPS SERVICE CENTER TRIED TO DIAGNOSE THE PROBLEM. THE BEST THEY CAME UP WITH WAS: A POSSIBLE AIR BUBBLE IN THE COOLANT AND THERMOSTAT FAILURE. BUT IT COULD BE ANYTHING ELSE, THEY ADDED. UPDATED 04/13/10.*JB
