Toyota VSC and ABS engaging and activating for no reason on dry pavement causing loss of proper control of the vehicle. The have been multiple occurrences on dry pavement between 30 and 65 mikes per hour. The car pulls to one side as the computer takes control of the car end engages the brakes suddenly for no reason. VSC Skid light goes on on the dash and there is a beeping sound while this happens. Very dangerous. Toyota USA notified and assigned case number 220201001364. They refuse to take any responsibility for this dangerous failure.

TRACTION CONTROL AND ABS ACTIVATED ON DRY ROADS ACTING LIKE THE VEHICLE THOUGHT IT WAS GOING INTO A SLIDE/SKID. THIS COULD HAVE CAUSED A SERIOUS CRASH!
NHTSA complaint #11372479 — an unverified report by a vehicle owner.
WHEN DRIVING IN PERFECTLY DRY CONDITIONS AND GOING ANYWHERE FROM 30-70 MPH ON A WINDING ROAD OR HIGHWAY, THE VSC LIGHTS WILL COME ON AND THE ALARM WILL SOUND AND YOU CAN'T ACCELERATE. IT'S VERY SCARY AND DANGEROUS BECAUSE YOU ARE NOT IN CONTROL OF THE VEHICLE. IT HAPPENS EVERY TIME WE GO FOR A DRIVE ON A WINDING ROAD OR HIGHWAY. I HAVE READ HUNDREDS OF SIMILAR COMPLAINTS FROM OTHER SIENNA OWNERS. IT'S CLEARLY A WIDESPREAD PROBLEM. TOYOTA NEEDS TO ISSUE A RECALL AS ALL THE REPAIR SHOPS WE HAVE GONE TO CANNOT FIGURE OUT HOW TO FIX THE PROBLEM.
NHTSA complaint #11365893 — an unverified report by a vehicle owner.
STABILITY CONTROL COMES ON INTERMITTENTLY WHILE DRIVING ON DRY ROAD SCARING ME AND PUMPING BRAKES AND PULLING CAR TO THE RIGHT FOR NO GOOD REASON AT HIGHWAY SPEEDS... ALARM SOUNDS ...VERY DISTRACTING AND DANGEROUS I PUSHED THE TRACK CONTROL BUTTON TO "OFF" POSITION AND IT STILL DOES IT!!!
NHTSA complaint #11365326 — an unverified report by a vehicle owner.
IN MOTION, ON DRY, OFF-CAMBER HIGHWAY CURVES, WITH SLIGHT ACCELERATION, THE ABS/VSC /TRAK ENGAGES, BRIEFLY JERKING THE STEERING TO ONE SIDE. DASH WARNINGS: "VSC" "TRAK OFF" + "CHECK ENGINE". REDUCING MECHANICAL "SLOP" (WHEEL BEARINGS, STEERING RACK & PINION, ETC.) TENDS TO REDUCE FREQUENCY OF OCCURRENCE. TOYOTA DEALER DIAGNOSIS: "STEERING CONTROL SYSTEM FAULT". >"TOYOTA KNOWS ABOUT -- BUT, DOES NOT KNOW HOW TO FIX THIS PROBLEM."< DEALER-SUGGESTED WORKAROUND: "PULL FUZES TO DISABLE VSC AND ABS SYSTEMS..." DEALER REPAIR DOCUMENTS ARE WITH PREVIOUS OWNER...
NHTSA complaint #11363702 — an unverified report by a vehicle owner.
WHEN DRIVING NORMALLY IN DRY CONDITIONS, THE VEHICLE STABILITY CONTROL ENGAGES WHEN MAKING SLOW TURNS AT ABOUT 45 TO 55 MPH. IT HAPPENS MOSTLY WHEN STEERING TO THE RIGHT BUT CAN HAPPEN WHEN TURNING LEFT. THIS RESULTS IN DANGEROUS DRIVING CONDITIONS WHERE THE BRAKES UNEXPECTEDLY ENGAGE OR THE CAR DOWN SHIFTS TO A LOWER GEAR. IT HAS ALMOST CAUSED A WRECK AND HAS PLACED ME AND OTHERS IN DANGER. THE PROBLEM BEGAN ABOUT 2 TO 3 YEARS AGO AND HAS BECOME PROGRESSIVELY WORSE. OTHER OWNERS OF THIS MAKE AND MODEL HAVE REPORTED SIMILAR ISSUES WITHOUT RESOLUTION BY TOYOTA, DEALERS OR AUTO REPAIR SHOPS. I AM ONLY ABLE TO RESOLVE THE ISSUE BY REMOVING THE FUSE THAT CONTROLS THE STABILITY CONTROL SYSTEM. SEE HTTPS://WWW.CARGURUS.COM/CARS/DISCUSSION-C9152_DS656326 FOR ONE EXAMPLE OF A DISCUSSION THREAD. GIVEN THE PERVASIVENESS OF THIS PROBLEM, IT IS APPARENT THAT THIS IS A SYSTEMIC PROBLEM WITH THE ENGINEERING OR MANUFACTURING OF THIS VEHICLES AND TOYOTA SHOULD BE HELD ACCOUNTABLE FOR THIS POTENTIALLY LIFE THREATENING PROBLEM.
NHTSA complaint #11362403 — an unverified report by a vehicle owner.
I HAVE A TOYOTA SIENNA 2005, MILEAGE 178000, SLIP INDICATOR TURNS ON RANDOMLY AND CAUSING THE CAR LOST CONTROL. IT IS EXTREMELY DANGEROUS WHEN IT HAPPENED OUT OF ZERO WARNING. IT'S NOT ONLY SCARE ME BUT ALSO MY CHILDREN IN THE CAR. IT HAS BEEN HAPPENED FOR OVER A YEAR SINCE SEPT. 2019. IT USUALLY HAPPENS WHEN DRIVING ON DRY CURVING ROADS AT SPEEDS 35-75 MPH. WHEN IT HAPPENED, THE ANTILOCK BRAKES ENGAGE, SLIP INDICATOR LIGHT COMES ON, AND ALARM SOUNDS, THE CAR'S BRAKES GRAB AND PULLS THE CAR TO THE SIDE. IT HAPPENS RANDOMLY, GOES AWAY, AND BACK TO NORMAL. I HAVE SENT THE MINI VAN TO A FEW MECHANICS FOR MULTIPLE TIMES BUT THEY CAN'T FIND OUT WHAT'S WRONG WITH IT. I HAVE REPLACED 4 BRAND NEW TIRES, DONE THE ZERO-POINT-CALIBRATION, MECHANICS COULDN'T FIND CODES FOR THE ISSUES, THEY HAVE TRIED EVERYTHING TO DIAGNOSE AND FIX THE PROBLEMS BUT IT JUST NEVER WORK. I LOVE MY MINI VAN BUT NOW I FEEL VERY UNSAFE TO DRIVE MY FAMILY WITH THIS MINI VAN. IT BOTHERS ME A LOT WHEN DRIVING THIS MINI VAN. MY ANXIETY LEVEL GO UP, ESPECIALLY, WHEN DRIVING ON CURVING ROADS. I WISH THIS SAFETY COMPLAINT WOULD CATCH THE ATTENTION. HOPEFULLY, TOYOTA WOULD RECALL THE VEHICLES AND FIX THE ISSUE FOR THEIR LOYAL CUSTOMERS, AND ALSO THE SAFETY OF THE PEOPLE AND THEIR FAMILIES RIDING THIS MINI VAN.
NHTSA complaint #11360899 — an unverified report by a vehicle owner.
I'VE ONLY HAD THE VAN FOR 5 MONTHS AND THIS PROBLEM HAS OCCURRED OVER A DOZEN TIMES, BEGINNING WITH THE DAY I BOUGHT IT. AND EVERY TIME THIS PROBLEM HAS OCCURRED I'VE BEEN DRIVING ON DRY ROADS. IT USUALLY HAPPENS WHEN DRIVING AROUND A CORNER, ANYWHERE FROM 35-65 MPH, FAR. ALL OF A SUDDEN THE TRACTION CONTROL LIGHT STARTS BEEPING, THE BRAKES ENGAGE ON THEIR OWN, AND THEN ENGINE MAKES A LOUD NOISE (LIKELY DOWNSHIFTING ITSELF). IT'S AS THOUGH THE VEHICLE THINKS IT IS SLIPPING, EVEN THOUGH IT IS NOT, I DRIVE VERY CAUTIOUSLY SO IT'S NOT ME FLYING AROUND A CORNER SUPER FAST, IT ALSO HAPPENS WHEN MY PARTNER DRIVES THE VAN AS WELL. I FINALLY TOOK THE VAN TO A MECHANIC AND THEY TOLD ME IT WAS THE STEERING ANGLE SENSOR THAT WAS FAULTY AND NEEDED TO BE REPLACED, SO I SPENT $900 TO HAVE IT REPLACED. I'VE HAD THE VAN BACK FOR LESS THEN 2 WEEKS AND JUST TRIED TO TAKE IT ON A ROAD TRIP, GOT ABOUT AN HOUR FROM OUR HOUSE AND IT DID IT AGAIN 3 TIMES IN LESS THEN 15 MINUTES, AGAIN DRIVING ON DRY PAVEMENT AND WHEN DRIVING ON A WINDY HIGHWAY. IT'S TERRIFYING WHEN THIS HAPPENS ESPECIALLY BECAUSE IT ALWAYS HAPPENS WHEN WE'RE GOING AROUND A CORNER, IT'S VERY DANGEROUS AND SCARY. IT SEEMS TO BE HAPPENING WITH A LOT OF OTHER SIENNA'S, EVEN NEWER ONES. THIS IS AN EXPENSIVE PROBLEM THAT DESPERATELY NEEDS TO BE ADDRESSED, SOMEONE IS GOING TO WRECK AND DIE FROM THIS IF THEY HAVEN'T ALREADY.
NHTSA complaint #11355155 — an unverified report by a vehicle owner.
I HAVE BEEN HAVING PROBLEMS WITH THE TRACTION CONTROL. THE LIGHT WILL RANDOMLY TURN ON, WHICH BRAKES THE WHEELS. THE SYSTEM WILL START BEEPING AND SAYING A FALSE TRACTION CONTROL PROBLEM. (WHEN THE ROAD IS CLEAR) I LOOKED ONLINE MANY TOYOTA SIENNAS HAVE THIS ISSUE. IT IS DANGEROUS AND SHOULD BE RECALLED TO BE FIXED!
NHTSA complaint #11354564 — an unverified report by a vehicle owner.
WHEN ENTERING A SLIGHT CURVE IN THE ROAD AT MODERATE IN TOWN SPEEDS THERE IS A CLICKING SOUND TO THE LEFT OF THE STEERING WHEEL IN THE DASH THEN THE TRACTION CONTROL SENSOR LIGHTT GOES ON. WHILE FREEWAY DRIVING, IT HAS HAPPENED 3 TIMES OUT OF THE BLUE AND WARNING BUZZERS SOUNDED VSC LIGHT AND TRACTION CONTROL LIGHT WENT ON AND THE STEERING JERKED...ENGINE LOST POWER ...VERY SCARY.I HAD RACK AND PINION STEERLING ASSEMBLY REPLACED AT ABOUT 40,000. THE PROBLEM STARTED AT ABOUT 110,000 MILES. I HAD ALL THE WHEEL SENSORS REPLACED AT ABOUT 115,000. I TOOK IT INTO TOYOTA DEALERSHIP THEY SAID THEY COULDN'T FIND A PROBLEM. TOOK IT TO 2 DIFFERENT MECHANICS ...ONE CHANGED THE SENSORS.COMPANY SAYS IT HASN'T BEEN A PROBLEM BUT ON THE INTERNET THERE ARE LOTS OF IDENTICAL POSTS. DEFINITELY A SAFETY ISSUE.I'VE HAD THE CAR 11 YEARS AND ALWAYS DID SCHEDULED MAINTENANCE. PLEASE SEE WHAT THE ISSUE IS.
NHTSA complaint #11349820 — an unverified report by a vehicle owner.
AS I DRIVE ON DRY ROADS AT SPEEDS BETWEEN 35 - 65MPH, MY CAR INDICATOR LIGHTS AND ALARM SOUND OFF ABOUT VSC (VEHICLE STABILITY CONTROL) AND SLIPPERY ROAD LIGHTS ON MY DASHBOARD. MY VEHICLE'S STEERING AND BRAKING ARE AFFECTED BY IT. IT STARTS TO RATTLE THE STEERING WHEEL AND THE BRAKING PUMPS - CAUSING A REDUCTION IN SPEED AND CONTROL FOR THE DRIVER. IT CAUSED ME TO FEAR A POSSIBLE VEHICULAR ACCIDENT SO MUCH THAT I PULLED OFF THE ROAD. THE PROBLEM THEN DISAPPEARS AND DOESN'T REAPPEAR UNTIL I ENCOUNTER A SIMILAR DRIVING CONDITION. I FEAR THAT IF THIS OCCURS ON A CROWDED HIGHWAY, IT WILL CAUSE ME TO GET INTO A VEHICULAR ACCIDENT DUE TO THE ABRUPT LOSS OF CONTROL. MY MINIVAN WAS PURCHASED TO KEEP MY FAMILY 'SAFER' AND THIS EXPERIENCE IS CAUSING ME TO FEAR USING THIS VEHICLE.AFTER CONDUCTING AN INTERNET SEARCH IT APPEARS TO BE HAPPENING TO TOYOTA SIENNA VEHICLES BETWEEN MODEL YEARS 2004 - 2008. MECHANICS DON'T SEEM TO UNDERSTAND HOW TO FIX OTHER THAN RESETTING THE SENSORS; WHICH DOESN'T FIX THE PROBLEM BUT JUST DELAYS ITS REAPPEARANCE. IN ALL CASES, I EXPERIENCED THIS PROBLEM ONLY WHILE DRIVING AT SPEEDS BETWEEN 35MPH AND HIGHER. IT'S OCCURRED ON DRY AND WET ROADS, USUALLY WHILE ON A CURVED ROAD.
NHTSA complaint #11349661 — an unverified report by a vehicle owner.
MY VSC AND SLIP DASHBOARD INDICATORS GO ON WHILE I DRIVE ON DRY ROAD AT SPEEDS BETWEEN 40-50 MPH. THE CAR THEN GIVES ME KICK BACK ON STEERING AND BRAKING, ALMOST AS IT LOSING CONTROL OF MY VEHICLE. IT THEN GOES AWAY RANDOMLY. IT IS DIFFICULT TO REPLICATE THE SITUATION BUT IT TENDS TO OCCUR ON SPEEDS ABOVE 35MPH AND ON A CURVED ROAD STEERING.THIS HAS OCCURED WHILE ON THE HIGHWAY AND ON REGULAR ROADS.
NHTSA complaint #11349659 — an unverified report by a vehicle owner.
WHILE DRIVING, THE TRACTION CONTROL SYSTEM WARNING CAME ON WHEN THE ROADS WERE CLEAR AND DRY. ALSO, THE AUTOMATIC BRAKING STARTED GOING OFF WHEN MAKING TURNS ON CLEAR ROADS. WHENEVER WE TRAVELED THE HIGHWAY AND WERE MAKING A TURN AT GREATER THAN 35 MILES PER HOUR, THE WARNING SOUNDED AND THE BRAKES WENT OFF.
NHTSA complaint #11343782 — an unverified report by a vehicle owner.
ON INCLINES, THE VSC LIGHT WOULD COME ON, CLICKING NOISE NEAR THE STEERING COLUMN. THE CAR WOULD LOSE POWER. I HAVE MECHANICS CHECKED OUT. CV JOINT AND BALL BEARING REPLACED. PROBLEM PERSISTS.

THIS HAPPENED TO OUR 2006 SIENNA TODAY I WAS ABOUT TO STOP THE CAR WHITE PARKING IT; WE PUT THE PARK THEY SILL RUN; THEY NEVER STOP, SO I TURN OFF THE ENGINE; NOW THEY NO MORE START VERY DAMAGED
NHTSA complaint #11337558 — an unverified report by a vehicle owner.
ABOUT A FIVE YEARS AGO THE SLIP INDICATOR LIGHT (CAR WITH SWERVY LINES) STARTED COMING ON INTERMITTENTLY WHILE TURNING ON HIGHWAYS ETC. (BUT NOT WHEN ANY RISK OF TIRES SLIPPING). I BROUGHT IT TO TOYOTA THREE DIFFERENT TIMES OVER THE YEARS AND TOYOTA ALWAYS STATES THEY CAN NOT DUPLICATE ISSUE AND STATES THEY CAN?T FIX IT BUT MAYBE DRIVE SLOWER (REALLY IT HAS NOTHING TO WITH MY SPEED AFTER YEARS OF DEALING WITH THIS ITS BEEN SOMETHING WE JUST DEAL WITH). THE VSC LIGHT ALSO COMES ON AND ALARM SOMETIMES SOUNDS WHILE DRIVING. TWO MORE TRIPS TO TOYOTA AND SEVERAL VISITS TO DIFFERENT MECHANICS AND NOBODY CAN FIND OUT THE PROBLEM. IN THE LAST 6 MONTHS THE ABS SYSTEM IS ALSO BEING ACTIVATED WITHOUT ME APPLYING THE BRAKES. IT DOES IT WITHOUT WARNING. ALL OF THESE ISSUES CAN BE ON A CURVE AT DIFFERENT SPEEDS OR ON A SLIGHT OR MEDIUM TURNS (NOT REAL SHARP TURNS), GOING UPHILL OR DOWNHILL AND LEFT OR RIGHT. OUR VAN HAS ABOUT 150,000 MILES ON IT NOW ON 2020 BUT WHEN THE PROBLEM FIRST STARTED IT ONLY HAD AROUND 110,000 MILES ON IT. WE HAVE CHANGED BRAKES, TIRES, ROTORS, BRUSHING ON ADVICE FROM DIFFERENT MECHANICS TO TRY TO FIX THE ISSUE. NOTHING WORKS. TOYOTA CANNOT FIGURE IT OUT. IT'S BECOMING MORE DANGEROUS BECAUSE NOW THE ABS IS BEING ACTIVATED WITH THIS PROBLEM. I CAN'T TELL IF MY BRAKE LIGHTS COME ON SO THAT DRIVERS BEHIND ME CAN TELL THAT I?M SLOWING DOWN VERY QUICKLY. THIS JERKS THOSE IN THE CAR AND I?M AFRAID WE MAY LOSE CONTROL. I HAVE READ ON DIFFERENT WEB SITES THAT THIS IS COMMON WITH A TOYOTA AND IT'S JUST NOT MY VAN. IF I HAD THE MONEY I WOULD BUY A DIFFERENT VEHICLE BUT BEING ON A FIXED INCOME I DON'T HAVE THE LUXURY TO DO SO. HOW CAN A CAR COMPANY HAVE SO MANY COMPLAINTS FROM CONSUMERS ABOUT THIS COMMON PROBLEM BUT STILL CAN'T TELL US HOW TO FIX IT? IT'S TOYOTAS DESIGN THEY SHOULD BE ABLE TO TELL THE CONSUMER WHAT IS CAUSING THIS ISSUE AND HOW TO FIX IT.
NHTSA complaint #11330408 — an unverified report by a vehicle owner.
THIS VEHICLE HAS A TRACTION CONTROL FEATURE WHICH HELPS KEEP IT FROM SKIDDING OUT OF CONTROL IN ICY, WET, OR OTHERWISE UNSTABLE CONDITIONS. IT CAN HELP AN OUT OF CONTROL VEHICLE GET BACK INTO CONTROL BY DOING A VARIETY OF THINGS, INCLUDING BRAKING. PREVIOUSLY THIS FEATURE HAD ONLY KICKED ON WHEN I WOULD SLIDE ON THE SNOW DURING A LOW SPEED TURN AND WOULD SLIDE IN THE SNOW (WHICH WAS GOOD). BUT OVER THE PAST FEW MONTHS, THERE HAVE BEEN TWO TIMES THAT THIS FEATURE HAS KICKED ON AT HIGH SPEEDS (ONCE AT 40MPH AND ONCE AT 65MPH) ON DRY ROADS, BOTH WHILE TURNING AROUND A CURVE. SUDDENLY THE BRAKING SYSTEM IS APPLIED WITHOUT ANY WARNING AND THE VEHICLE SWERVES SLIGHTLY AND DOES WHAT IT WANTS FOR A FEW SECONDS. THEN IT STOPS. IF THIS WERE TO HAPPEN ON AN ICY ROAD AT THOSE SPEEDS, THE VEHICLE COULD CERTAINLY SPIN OUT OF CONTROL. THE VEHICLE COULD ALSO SWERVE INTO AN ONCOMING LANE OF TRAFFIC. I HAVE SEEN MANY FORUMS ONLINE WHERE OTHER SIENNA OWNERS ARE HAVING THE SAME ISSUE AND TOYOTA DEALERS SAY THEY CAN'T REPLICATE OR FIX THE ISSUE. THIS IS CERTAINLY A SAFETY ISSUE THAT NEEDS TO BE LOOKED INTO BY TOYOTA TO SEE WHAT IS CAUSING THIS ISSUE. THANK YOU!
