2006 Toyota Sienna electronic stability control (esc) problems

“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!!!”

“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”

“RANDOMLY, ON GENTLE TURNS OUR VAN WILL SUDDENLY BRAKE WITH TRACTION CONTROL LIGHTS AND BEEPING AS WELL. IT IS ALWAYS ON A WINDY HIGHWAY AT SPEEDS GREATER THAN ABOUT 35 MPH. WE ARE SLOWER THAN AVERAGE CAUTIOUS DRIVERS. THIS SEEMS VERY DANGEROUS TO BE HAPPENING WITHOUT PROVOCATION. I HAVE DONE AN ENORMOUS AMOUNT OF RESEARCH ON THIS AND HAVE FOUND A MYRIAD OF OTHER PEOPLE EXPERIENCING THE SAME SAME PROBLEM, AND ALL HAVE FOUND NO FIX FOR THE ISSUE. THEY USUALLY GO TO THE DEALER MULTIPLE TIMES WITH NO SUCCESS. I DON'T HAVE THE FUNDS TO GO ROUND AND ROUND WITH THE DEALER TO END UP WITH A REPAIR THAT STILL ISN'T RESOLVED. PLEAS HELP. THANK YOU.”

“AT SPEEDS OF ANYWHERE BETWEEN 30-60 MPH, TRACTION CONTROL SYSTEM ENGAGES WHEN TURNING SLIGHTLY LEFT. ALARM COMES ON, BRAKES ARE AUTOMATICALLY APPLIED. VERY DANGEROUS”

“THE TRACTION CONTROL IS MALFUNCTIONING AND TURNING ON DURING NORMAL DRIVING CONDITIONS. THERE IS A LOUD BEEPING AND THE TRACTION CONTROL LIGHT TURNS ON WHILE TURNING. THIS HAS HAPPENED AT VARIOUS SPEEDS FROM 35 MPH ON A CITY STREET TO 65 MPH ON FREEWAYS. WHAT IS REALLY ALARMING IS THAT SOMETIMES WHILE THE LIGHT TURNS ON THE SYSTEM APPLIES THE BRAKES TO ONE WHEEL PULLING THE VEHICLE SUDDENLY TO ONE SIDE. THIS IS VERY DANGEROUS AT HIGH SPEEDS. I HAVE REPLACED MANY PARTS- SHOCKS, CONTROL ARMS, JOINTS AND TAKEN IT TO MULTIPLE MECHANICS. THIS IS A COMMON PROBLEM WHEN SEARCHING THE WEB BUT NOBODY IS ABLE TO FIND A SOLUTION.”

“WHEN DRIVING AT SPEEDS OF 38 MPH OR MORE AND TURNING THE STEERING WHEEL/TIRES, THE VSC WARNING ALARM WILL GO OFF. WHEN THIS HAPPENS, THE CARS AUTOMATICALLY BRAKES. THIS HAPPENS WHEN THERE ARE NO PROBLEMS WITH THE DRIVING CONDITIONS. THE SEVERITY OF THE BRAKING AND LENGTH OF ALARM VARY. IT IS ESPECIALLY PROBLEMATIC ON TIGHT TURNS. IT DOES NOT MATTER WHETHER YOU ARE GOING UPHILL, DOWNHILL, OR TURNING ON A FLAT ROAD. WE DO NOT KNOW WHAT IS CAUSING THIS UNSAFE ISSUE. WE HAVE TRIED TURNING OFF THE TRAC. IT MADE NO DIFFERENCE.”
