“The contact owns a 2005 Ford F-150. The contact stated while driving approximately 30 mph and depressing the brake pedal, the brake pedal traveled to the floor. The driver immediately turned the steering to avoid hitting several kids that were crossing the street. During the failure, the brake warning light illuminated. The cause of the failure was not yet determined. The local dealer was notified of the failure. The contact was informed that the part to replace the ABS module was no longer produced by the manufacturer and was therefore unavailable for a repair.

“TL* THE CONTACT OWNS A 2005 FORD F-150. THE CONTACT STATED THAT WHILE DRIVING 65 MPH, THE BRAKES STARTED TO PULSATE AND THE STEERING WHEEL JERKED VIOLENTLY. THE VEHICLE WAS TAKEN TO THE DEALER WHO DIAGNOSED THAT THE ROTORS WERE WARPED AND AS A RESULT, THE ROTORS NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE AND THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 12,000 AND THE CURRENT MILEAGE WAS 31,000. UPDATED 03/16/12*LJ UPDATED 04/19/12”

“TL* THE CONTACT OWNS A 2005 FORD F-150. THE CONTACT STATED THE FRONT ROTORS HAD TO BE REPLACED TWICE BECAUSE THEY WERE WARPED. THE FAILURE CAUSED THE STEERING TO WHEEL TO SHAKE VIOLENTLY WHEN DRIVING AT HIGH SPEEDS AND BRAKING. THE CONTACT ALSO STATED THAT THE ROTORS WERE REPLACED TWICE WITHIN 7,000 MILES OF DRIVING. THE DEALER HAD NOT GIVEN A REASON FOR WHY THE FAILURE OCCURRED. THE FAILURE MILEAGE WAS 23,000 AND THE CURRENT MILEAGE WAS 30,000.”

“TL* THE CONTACT OWNS A 2005 FORD F-150. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 30 MPH UPHILL, THE BRAKES BEGAN PULSATING AS THE CONTACT DECELERATED.

WHILE TRAVELING AT 70MPH ON I-10 WITH THE SPEED CONTROL ENGAGED, I WENT TO EXIT THE HIGHWAY TO GET FUEL AND WHILE DEPRESSING THE BRAKE PEDAL TO REDUCE SPEED, THE SPEED CONTROL BEGAN ATTEMPTING TO RESUME THE ORIGINAL 70MPH SPEED BY REVVING THE ENGINE. LATER I DETERMINED THAT THE ALTERNATOR ON THE VEHICLE HAD FAILED AND WHILE THE BATTERY HAD ENOUGH VOLTAGE TO KEEP THE ENGINE RUNNING AND THE VOLTAGE GAUGE HAD NOT MOVED YET, THE BATTERY DID NOT HAVE A FULL 12.5V OUTPUT.
