NHTSA Complaint #10394568 — 2010 TOYOTA COROLLA

1. THIS CAR CAN NOT BE DRIVEN IN A STRAIGHT LINE ON THE HIGHWAY EVEN WHEN YOU HOLD STEERING WITHOUT MOVING. IT SEEMS VEHICLE SLOWLY, CONSISTENTLY DRIFTS MOSTLY TO THE LEFT AND TO THE RIGHT. ONE NEEDS TO PAY SO MUCH ATTENTION ON STEERING WHILE DRIVING. THIS PROBLEM HAS BEEN THERE SINCE DAY ONE (8 MILES) AND I REQUESTED TO FIX BEFORE I SIGN THE PAPER WORK BUT NOT HAS BEEN TAKEN CARE OTHER THAN CAR WASH. THIS ISSUE STILL EXISTS EVEN AFTER PERFORMING ALIGNMENT DURING OUR FIRST SERVICE VISIT AS I THOUGHT IT WAS AN ALIGNMENT ISSUE. WE BELIEVE IT IS A VERY SERIOUS ISSUE THAN STICKY PEDAL AND POSE A POTENTIAL RISK FOR COROLLA OWNERS IF WE CAN NOT CONTROL STEERING. IT HAS POTENTIAL ROAD HAZARD AS THE VEHICLE WANDERS BOTH LEFT AND RIGHT ESPECIALLY WITH HEAVY TRAFFIC AND FEELS LIKE CAR WHEELS ARE NOT UNDER CONTROL. WE ARE POSITIVE THAT THESE STEERING/SUSPENSION ISSUES WERE ALSO RAISED ON OTHER 2010 COROLLAS BY A NUMBER OF OWNERS. TOYOTA AND DEALERS MUST BE FULLY AWARE OF THESE CONCERNS BUT FAILED TO DECLARE UP FRONT. DURING OUR SECOND VISIT THEY TOLD US ABOUT TS 1040 AND REPLACED STEERING CONTROL COMPUTER BOARD. SEEMS WANDERING ISSUE IS GONE FOR NOW. BUT TIRES ARE PROBLEM AS I AM HAVING CONCERN FROM THE BEGINNING. 2. I FEEL HUMMING MILD VIBRATION/RESONANCE IN STEERING WHEEL WHEN WE CROSS 50-60 MPH. IT FEELS LIKE TIRES ARE VIBRATING THE STEERING WHEEL. REPLACING COMPUTER CONTROLLER DID NOT FIX MILD VIBRATION OF STEERING. 3. TIRES: AS I HAD DOUBT ABOUT TIRES THIS COULD BE TIRES PROBLEM BUT TOYOTA SERVICE TEAM IS NOT WILLING TO ACCEPT THE FACT. ONCE YOU CROSS 62 MPH YOU CAN CLEARLY FEEL THE TIRE VIBRATION MAINLY IN A STEERING WHEEL AND ALSO ON THE VEHICLE. ROAD FORCE BALANCING HAS BEEN DONE BUT THERE IS NO IMPROVEMENT. I AM NOT SURE IT IS ENGINE RELATED OR TIRES. I HAVE BEEN INSISTING ON REPLACING ANOTHER SET OF BETTER BALANCED TIRES OR DIFFERENT MAKE OF TIRES.
