NHTSA Complaint #10970378 — 2005 TOYOTA SIENNA

WHILE DRIVING AROUND CURVES WITH DRY PAVEMENT ON HIGHWAYS AND EXIT/ENTRANCE RAMPS AT HIGHWAY RATES OF SPEED (55-65 MILES PER HOUR OR LESS) THE ANTI-LOCK BRAKE SYSTEM ENGAGE,S CAUSING THE VAN TO PULSE AND SLOW DOWN UNEXPECTEDLY. IT DISENGAGES ONCE THE WHEEL STRAIGHTENS. WE FIRST TRIED TO TROUBLE SHOOT WITH OUR LOCAL MECHANIC WITH NO SUCCESS, PROMPTING US TO HAVE OUR LOCAL TOYOTA SERVICE DEPARTMENT ATTEMPT TO DIAGNOSIS. INITIALLY THEY SAID THEY WERE NOT ABLE TO DIAGNOSIS THE PROBLEM OR REPLICATE IT ON A LOCAL HIGHWAY (AS IT DOES NOT OCCUR ON EVERY CURVE ENCOUNTERED) AND WERE READY TO SEND US HOME WITHOUT ANY REMEDY. THIS WAS UNACCEPTABLE. WITH OUR PERSISTENCE THEY HOOKED IT UP TO A COMPUTER AND DETERMINED(WITHOUT GUARANTEEING) IT WAS THE STEERING ANGEL SENSOR AND REPLACED IT. NOW WITHOUT RETURNING THE VAN TO US, THEY WANT US TO REPLACE THE RACK AND PINION SYSTEM FOR EVEN MORE COST, AGAIN, WITHOUT GUARANTEEING THIS WILL ALLEVIATE THE PROBLEM. PER OUR READING UP ON THIS PROBLEM, WE HAVE FOUND THAT THIS APPEARS TO BE PROBLEM FOR OTHER 2005 TOYOTA SIENNA MINIVANS.
