Brake Drum Wheel Cylinder problems of the 2017 Ford F-150

Tl- the contact owns a 2017 Ford F-150. The contact stated that brake pedal had hardened without warning which had made it difficult to depress the brake pedal when traveling at various speeds. The contact had taken the vehicle to tindol Ford(1901 e franklin blvd, gastonia, nc 28054) where an inspection was performed on the vehicle however the dealer found no fault with his brakes or brake cylinder. Upon investigation, the contact linked his failure to NHTSA campaign number: 20v332000 (service brakes, hydraulic); however, his vehicle was not included in the recall. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 27,000.

Driving from California to oregon through nevada on interstate when vehicle started to overheat nevada dealer would not even look at the vehicle. Informed Ford motor company. Continued to oregon and then on to bozeman montana. Vehicle is now at bozeman Ford having the motor dismantled for diagnosis. Was told there is a issue with the number one cylinder, Ford corporation has not been of any help what so ever.

Master brake cylinder went out at 6,267 miles- brake pedal went to floor while at intersection- was able to pump up - had to pump up every time vehicle was shut off and failed once after pumping up at traffic light.

On 08/07/2017 while traveling approximately 55 miles per hour on highway 281 in san antonio, TX my 2017 Ford F-150, v8 super crew, 4x4 ftx experienced complete brake failure. My brakes went to the floor with no brake activation and I had to swerve to the left two lanes to avoid impacting the vehicles in front of me. Once on the shoulder I had to pump the brakes in order to stop after travelling several hundred yards. There was absolutely no warning (noise, service lights, etc. ) prior to, during or after the brake failure. The vehicle was only four months old with 6400 miles on it. If there was no shoulder or clear lanes it would have caused a severe accident likely resulting in injuries. I was able to slowly and carefully make my way to the dealership on side roads but experienced total brake failure three additional times. The first time was while I was stationary at a stop sign facing slightly downhill my brake pedal went completely to the floor and I had to pump it several times to make the vehicle stop again. The other two times I was traveling approximately 25 miles per hour and missed my turn (right) and proceeded past the turn approximately 50 yards and had to pump the brakes in order to stop. The dealership had to remove and replace the master brake cylinder. They indicated it was leaking internally and gave no explanation why a service light or other warning did not come on and there is no current recall for that part.
