2007 TOYOTA SIENNA Electronic Stability Control Esc Problems

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.

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...

AT RANDOM SPEEDS, ON CURVES AND STRAIGHTAWAYS, THE TRACTION LIGHTS ALARMS AND ENGAGES THE BRAKES. THIS SEEMS REALLY DANGEROUS. OUR MECHANIC DOESN'T KNOW WHAT IS THE CAUSE OR HOW TO FIX IT.

I HAD THE FRONT BRAKES AND ROTORS REPLACED A FEW WEEKS AGO. THIS PAST WEEKEND ALL 4 TIRES WERE REPLACED. WHEN DRIVING OFF THE DEALER AFTER THE TIRE REPLACEMENT, I NOTICED THE ABS AND VSC LIGHTS WERE ON. TURNED BACK AND TOOK THE MINIVAN BACK TO THE DEALER. NEXT DAY SERVICE MGR SAID ACCORDING TO THE MECHANIC, THE ABS ACTUATOR NEEDS TO BE REPLACED. THIS IS A $2500 PART, PLUS LABOR.

INTERMITTENT VSC ACTIVATION AFTER STARTING THE ENGINE AND DRIVING STRAIGHT FROM A STOP POSITION. THIS CONDITION IS ALWAYS ACCOMPANIED BY THE INSTRUMENT PANEL VSC LIGHT AND AUDIBLE WARNING BUZZER TURNING ON AT THE SAME TIME. BRAKES ACTIVATED AT SAME TIME CAUSING SKID

THE SLIP INDICATOR SENDS A FALSE POSITIVE WHICH CAUSES THE BRAKES TO APPLY AUTOMATICALLY WHEN I GO OVER 10 MPH. THE ROAD IS DRY, WEATHER CLEAR AND THERE IS NO POOR CONDITIONS FOR DRIVINGTHE VEHICLE IS UNSAFE BECAUSE WHILE I AM DRIVING IT CAN COME TO AN ABRUPT HALT AND THE VEHICLE BEHIND ME COULD CRASH INTO ME.THE VEHICLE OVERRIDES MY ATTEMPT TO ACCELERATE AND I AM SUBJECT TO THE 'COMPUTER'S DECISION TO BRAKE UNNECESSARILY. I HAD A DEALER LOOK INTO THIS AND THEY SAID IT WAS THE BRAKES. I HAVE ALWAYS BEEN A LOYAL TOYOTA CUSTOMER, BUT THERE ARE MANY COMPLAINTS ABOUT THIS PROBLEM SOME OF WHICH ARE ON YOUTUBE AND TOYOTA SEEMS TO BE UNWILLING TO ADDRESS THIS ISSUE. PLEASE HELP I NEED MY VEHICLE AND I NEED TO BE SAFE WHILE DRIVING.

THE VEHICLE STABILITY CONTROL SYSTEM (VSC) IS MALFUNCTIONING. AT RANDOM TIMES WHEN THE VEHICLE IS IN MOTION THE SYSTEM GOES OFF AND BEGINS APPLYING THE BREAKS. THIS IS VERY DANGEROUS, AND CAUSES THE VEHICLE TO BE UNCONTROLLABLE. THIS PROBLEM IS NOT RELATED TO SLICK OR WET ROAD CONDITIONS. IT HAPPENS IN COLD AND DRY HOT WEATHER. IT IS ALSO NOT RELATED TO SPEED AS THE PROBLEM CONTINUES WHEN I DRIVE WELL BELOW THE SPEED LIMIT. I HAVE TAKEN THE VAN TO THE DEALER, AND BEEN TOLD THERE IS NOTHING WRONG. I AM VERY CONCERNED FOR THE SAFETY OF MY FAMILY.
