NHTSA Complaint #10883251 — 2005 TOYOTA SIENNA

WHILE DRIVING AT APPROXIMATELY 40 MPH AND ENTERING A LEFT TURN CURVE, THE ABS AND VSC LIGHTS ACTIVATED AND THE VEHCLE LURCHED VIOLENTLY TO THE RIGHT THEN BACK TO THGE LEFT. I WAS ABLE TO REGAIN CONTROL AFTER A FEW SECONDS, BUT DURING THIS TIME TIME I WAS NOT ABLE TO STEER PROPERLY. THE VEHICLE WAS TAKEN TO AN INDEPENDENT SERVICE FACILITY. THE BRAKES AND STABILITY CONTROL WERE INSPECTED. THERE WERE NOT ANY TROUBLE CODES STORED. EXAMINATION OF THE WHEEL SPEED SENSORS REVEALED THE RIGHT AND LEFT SENSORS WERE SEIZED IN THEIR MOUNTING BRACKETS. WE BELIEVE THE SENSORS HAVE RUSTED AND HAVE SWOLLEN. WE HAD THE ABS AND VSC SYSTEMS DISCONNECTED. THE PROBLEM HAS NOT OCCURRED SINCE THIS WAS DONE. WE ARE PLANNING ON REPLACING THESE SENSOR IN THE NEAR FUTURE. THIS IS A VERY SERIOUS CONDITION AND NEEDS TO BE INVESTIGATED.
