WHILE STOPPING VEHICLE, BRAKING BECAME NON-RESPONSIVE AND ENGINE BEGAN RACING. VEHICLE WAS EXTREMELY DIFFICULT TO STOP COMPLETELY. AFTER TAKING FOOT OFF OF BRAKE PEDAL, VEHICLE LUNGED FORWARD AS IF ACCELERATOR PEDAL WAS FULLY DEPRESSED. THIS HAS OCCURRED ON 12/9/12 , 12/10/12, 12/15/12. INFINITI HAS NOT CORRECTED PROBLEM. THIS RAPID ACCELERATION / NON-RESPONSIVE BRAKING HAS CAUSED TWO (2) NEAR MISS ACCIDENTS.

TL* THE CONTACT OWNS A 2009 INFINITI G37. WHILE THE VEHICLE WAS PARKED, THE VOC WARNING LIGHT ILLUMINATED ON THE INSTRUMENT PANEL. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE TECHNICIAN STATED THE REAR BRAKE PADS NEEDED TO BE REPLACED AND THE REAR ROTORS NEED TO BE RESURFACED. AFTER THE VEHICLE WAS REPAIRED, THE CONTACT HEARD A CLICKING NOISE WHILE DRIVING APPROXIMATELY 10 MPH AND DEPRESSING THE BRAKE PEDAL. THE VEHICLE WAS TAKEN BACK TO THE DEALER FOR DIAGNOSTIC TESTING. THE TECHNICIAN NOTICED EXCESSIVE VIBRATION WHEN THE BRAKES WERE APPLIED AND STATED THE REAR ROTORS HAD TO BE RESURFACED, AND THE REAR BRAKE PADS HAD TO BE REPLACED A SECOND TIME. THE SWAY BAR BUSHINGS WERE ALSO REPAIRED. THE FAILURE CONTINUED TO OCCUR AFTER THE VEHICLE WAS REPAIRED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC FOR DIAGNOSTIC TESTING. THE MECHANIC STATED THE BRAKE PADS HAD TO BE REPLACED BECAUSE THEY DID NOT FIT PROPERLY WITH THE REAR DISKS WHICH CAUSED EXCESSIVE WEAR ON THE BRAKE PADS AND ROTORS. THE MECHANIC REPLACED THE REAR BRAKE PADS. THE APPROXIMATE FAILURE MILEAGE WAS 15,686. UPDATED 07/02/12 *BF UPDATED 07/10/12

TECHNICAL SERVICE BULLETIN ITB09-037 FROM INFINITI STATES OVERHEATING OF THE BRAKES CAN CAUSE BRAKE JUDDER. THEY RECOMMEND INSTALLING A BRAKE BACKING PLATE, RESURFACING, OR REPLACING THE ROTORS. I TOOK MY CAR TO MY INIFINITI DEALER AND THE PLATE WAS INSTALLED. THE FRONT ROTORS WERE RESURFACED, BRAKE PADS REPLACED, AND I STILL HAD THE BRAKE JUDDER. I TOOK IT BACK AND THEY RESURFACED THE REAR ROTORS AND RECOMMENDED BALANCING AND ROTATING TIRES. I DID THIS (AT MY OWN COST) AND THE BRAKE JUDDER IS STILL PRESENT. THE CAR HAD 15,000 MILES WHEN THE PROBLEM OCCURRED. I FEEL A MANDATORY REPLACEMENT OF THE ROTORS AND THE PADS AT THE SAME TIME IS REQUIRED. THE WARPED ROTORS CONTINUE TO CAUSE VIBRATION AFTER RESURFACING AND MY DEALER WILL NOT REPLACE THEM AT COST. *TR

VEHICLE VIBRATES WHEN BRAKING. DEALERSHIP FOUND ALL FOUR ROTORS OUT OF ROUND. DEALERSHIP ALSO FOUND REAR ROTORS WARPED. DEALERSHIP CUT FRONT ROTORS AND RESURFACED REAR ROTORS. *TR
