2001 Toyota Sequoia Electronic Stability Control Esc Traction Control System Problems

2001 TOYOTA SEQUOIA YAW SENSOR FAILED WHILE ON I95, CAUSING A LOUD WARNING BUZZER, THE VSC WARNING LIGHT ON DASHBOARD STARTED FLASHING, TRACTION CONTROL WARNING INDICATOR FLASHED, BRAKES WERE UNABLE TO QUICKLY SLOW THE SUV AND A LOUD GRINDING NOISE UNTIL THE CAR COASTED TO A STOP. WE HAD TO PAY TOYOTA TO REPLACE THE YAW SENSOR, THE SECOND TIME SINCE WE BOUGHT THE CAR IN 2001. THE FIRST REPLACEMENT WAS IN 2003/4. WE HAVE DOCUMENTED OVER TEN COMPLAINTS TO DEALER SINCE PURCHASE THAT VSC LIGHTS WOULD NOT TURN OFF AFTER STARTING TRUCK. *TR

MY 2001 TOYOTA SEQUOIA IS EXPERIENCING FALSE SKID INDICATIONS RESULTING IN DANGEROUS APPLICATIONS OF THE RIGHT FRONT WHEEL BRAKE. THE INDICATIONS ARE ILLUMINATION OF THE SKID SYMBOL, RAPID ANTISKID SERVO ACTION, RIGHT FRONT WHEEL BRAKE APPLICATION WHICH LAST FROM ONE SECOND TO AS MUCH AS 30 SECONDS. ONCE THE RIGHT FRONT BRAKE APPLICATION STOPS, THE SKID SYMBOL IS NO LONGER ILLUMINATED AND THE TRAC OFF AND VSC TRAC LIGHTS ILLUMINATE. THIS OCCURS IN ALL DRIVING CONDITIONS AT LOW OR HIGH SPEED, SMOOTH ROAD SURFACES, AND WHETHER GOING STRAIGHT OR TURNING. I HAVE HAD THE TOYOTA SERVICE DEPARTMENT CONNECT THEIR COMPUTER SEVERAL TIMES TO DETERMINE A CAUSE AND THEY CAN NOT DEFINITIVELY TELL WHAT HAS FAILED. SOMETIMES THEY TELL ME IT COULD BE THE YAW SENSOR OR THE SKID CONTROL ECM, BUT THESE ARE VERY EXPENSIVE PARTS THAT MAY OR MAY NOT FIX THE PROBLEM. THIS PROBLEM HAS BEEN OCCURRING FOR ABOUT A YEAR. INITIALLY, THE FIRST SIGN OF A PROBLEM WITH THE CAR OCCURRED WHILE DRIVING AT 35 MPH AND THE THROTTLE WENT TO IDLE AND THE TRAC OFF, VSC TRAC, AND ENGINE LIGHTS ILLUMINATED. TOYOTA SAID IT WAS THE THROTTLE CABLE AND THROTTLE SENSOR AND I PAID THEM TO REPLACE BOTH PARTS. SHORTLY AFTER THIS, THE FALSE SKID FAILURES BEGAN. THE FALSE SKID FAILURES OCCUR RANDOMLY AND WITHOUT WARNING AND RECENTLY, THE FREQUENCY OF OCCURRENCE HAS INCREASED. *TR
