2017 Ford Expedition Brakes Problems

“The brakes went out suddenly. After taking to a mechanic we were informed that the master cylinder had a catastrophic failure which resulted in leaking brake fluid corroding the brake booster. Research has LED me to believe that this is a common problem found in these vehicles. Thankfully my wife was only backing out of the driveway when it happened so she did not have an accident.”

“Total brake failure while backing up , almost hit another vehicle, shifted to forward to avoid accident , loss of brake fluid in master cylinder to brake booster. Exact symptoms as recall 20s31 with 2014 to 2017 f150. The Expedition is on af150 chassis . According to dealer not under recall but probably should be. Out of warranty. Repaired on my dime. Replaced master cylinder and cleaned booster. Vehicle was in motion at time of incident. Just glad I wasn't on the boat ramp or highway”

The car at this point was beginning to decelerate almost to a stop so I inched car onto an unpaved area. …”

The my Expedition has they same issue . The f150 and Expedition are the same under the hood. The vehicle is safety hazard due to this issue.”

“Below please find my account of a very frightening event that took place when my 2017 Ford Expedition malfunctioned. In late august, 2018 we were on vacation in seattle, wa., visiting my son and his family. Five of us were in my Expedition and my son was driving. We pulled up to park by his house on a steep road. He put the vehicle into park, applied the parking brake, removed the keys, and proceeded to get out. There were three adults and two children (ages 7 and 4). All three adults got out and were helping the children out when the car rolled forward on its own. …”
