DEARBORN, Mich. – Ford is recalling certain 2021 F-150 pickup trucks which might experience reduced braking capability due to brake fluid leaking into the brake system’s electronic control unit (ECU).

The recall affects 51 pickup trucks manufactured between Dec. 11, 2020, and Jan. 31, 2021, according to the National Highway Traffic Safety Administration’s Part 573 Safety Recall Report 21V-533.

Affected vehicles were built with electronic brake boosters that were incorrectly manufactured by the supplier, creating a leak path for brake fluid to migrate into the ECU.

NHTSA reported, “A brake booster with an incomplete clinch between the pressure sensor and the brake booster housing will cause brake fluid to leak through the pressure sensor into the brake booster control unit. Customers may experience longer pedal travel, higher pedal efforts and reduced braking, increasing the risk of a crash.”

According to the federal agency, neither it nor Ford is aware of any accidents due to this situation. There have been 12 reported warranty claims for this issue.

Owners will be notified by mail and instructed to take their vehicle to a Ford or Lincoln dealer to have the electronic brake booster assembly replaced at no charge.

The replacement electronic brake boosters (Part number: ML34-2D335-AR) will have a complete clinch between the pressure sensor and the brake booster housing.

Dealers are scheduled to begin receiving recall notification July 16th and owners July 26th.
