NHTSA Complaint #10498541 — 2013 AUDI S4

AUDI'S ELECTRONIC ASSISTED STEERING ON MY S4 EXHIBITS UNPREDICTABLE BEHAVIOR WHICH COULD RESULT IN AN ACCIDENT. IT HAS A "NOTCH" AT 12 O'CLOCK WHERE THE CAR USUALLY DOES NOT RESPOND TO WHEEL INPUTS UNTIL YOU TURN IT MORE THAN AN INCH IN EITHER DIRECTION. WHEN IT DOES FINALLY REACT, IT OFTEN OVERCOMPENSATES. IT DOES NOT ALWAYS HAPPEN HOWEVER. SOMETIMES THE NOTCHINESS IS PRESENT, SOMETIMES IT'S NOT EVEN ON THE SAME STEERING SETTINGS/SAME SPEED. I CAN NOT KEEP THE CAR GOING STRAIGHT AT TIMES. THE SLIGHTEST MOVEMENT TO THE RIGHT STEPS IT OVER INTO WHAT FEELS LIKE THE NEXT GROOVE AND I START SLIGHTLY HEADING OFF THE ROAD TOO THE RIGHT, TRY TO CORRECT AND IT STEPS A NOTCH OVER TO THE LEFT AND I START SLOWLY CHANGING LANES THAT DIRECTION. *TR
