Certain 2016-2018 Ford and Lincoln, trucks and SUVs equipped with 3.5L Ecoboost engines could require more braking effort and distance to stop the vehicle. Ford will be asking owners to return to their dealerships for repairs.
In May 2016, Ford issued a recall (16V-345) for F-150s equipped with the 3.5L Ecoboost engines, because the brake master cylinder could leak and allow brake fluid from the front wheel circuit into the brake booster. After continued field data monitoring and discussions with NHTSA, Ford issued a second recall (20V-332), to extend the population for F-150s.
Ford continued to monitor field reports expanding the coverage into Ford Expedition and Lincoln Navigator vehicles built during the same period. These vehicles share a similar brake master cylinder design as the F-150 3.5L Ecoboost vehicles
Investigation into supplier records and discussion with the supplier identified additional steps taken by the supplier to further improve brake master cylinder seal installation from August 2016 to December 2016. These include an automated process to remove imperfect threads from the master cylinder outlet port, as well as actions to improve the installation of the rearmost cup seal in the master cylinder. Master cylinders with these improvements were incorporated into vehicle production by January 31, 2017.
In March 2022, Ford’s Field Review Committee reviewed the concern and approved a safety
recall action. Ford is aware of 4 low-speed/low-impact accident allegations with no injuries.
