IllustrationI LEASED A NEW INFINITI QX56. THE BRAKES FAILED AT 2500 MILES AND PADS AND ROTORS HAD TO BE REPLACED. MY CAR IS BEING SERVICED AGAIN TODAY FOR THE SAME REASON. THE STEERING WHEEL SHAKES UNCONTROLLABLE WHEN THE BRAKES AND ROTORS WEAR. I HAVE BEEN DRIVING FOR OVER 20 YEARS AND HAVE NEVER HAD BRAKES FAIL EVERY 2500 MILES!
