2008 Toyota Sienna electronic stability control (esc) problems

“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.”

“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.”

“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.”

“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.”

“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…”

“VEHICLE WOULD ENGAGE BRAKES BY ITSELF AND VSC AND TRACTION CONTROL LIGHTS WOULD START FLASHING AND BEEPING WHEN GOING AROUND CURVES OR HITTING BUMPS IN THE ROAD. THIS WAS FRIGHTENING, AND CAUSED ME TO NOT IN GOOD CONSCIENCE SELL THE VEHICLE OUTRIGHT TO ANOTHER PERSON, SO I LOST THOUSANDS OF DOLLARS BY TRADING IT IN. THIS HAPPENED INTERMITTENTLY FOR OVER A YEAR. ESTIMATED FINANCIAL LOSS $4000.00. *TR”
