NHTSA Complaint #10664488 — 2014 KIA OPTIMA

AT ANY SPEED ABOVE 30 MPH, THE STEERING SYSTEM HAS A DELAYED RESPONSE. AS YOU TORQUE THE STEERING TO HOLD A POSITION ON A CROWNED ROAD SURFACE, THE STEERING FINALLY RECOGNIZES A STEERING INPUT COMMAND AND IMMEDIATELY JUMPS TO THE NEW POSITION. NOT ONLY IS IT DISCONCERTING, BUT DEPENDING ON THE ROAD CONDITION (TRAFFIC, LANE WIDTH, OVERALL SPEED) THESE "DIGITAL" JUMPS IN POSITIONING OF THE STEERING WHEEL RESULT IN SIGNIFICANT DRIFTING TO THE LEFT OR RIGHT. I HAVE FOUR CARS, THIS IS THE ONLY "FLY BY WIRE" CAR OF THE LOT. ALL OTHERS HAVE "ANALOG" STEERING WHICH ENABLES CONTINUOUS PRESSURE TO BE APPLIED TO THE STEERING SYSTEM TO MAINTAIN POSITION ON THE ROAD. THIS IS AN EXTREMELY UNSAFE SITUATION. I HAVE THE TURBO OPTIMA. THE DEALER "SOLUTION" WAS TO "TAKE THE STEERING OFF SPORT MODE" AND PUT IN STANDARD MODE. I DIDN'T BUY A TURBO VEHICLE TO BE FORCED TO OPERATE IT LIKE A STANDARD OPTIMA. THE STEERING PERFORMANCE IS FAR LESS IN STANDARD MODE AND MAKES THE VEHICLE RESPONSE SLUGGISH. *TR
