Ford issued a do-not-drive warning and recall for more than 312,000 vehicles due to potential loss of power brake assist.
The automaker estimates the problem could exist in just 1% of the 2025 vehicles but recalled all potentially affected due to the risk of crash. They are the Bronco, F-150, Expedition, Lincoln Navigator and Ranger.
Ford said the vehicles’ electronic brake booster module could “enter a faulted state” while in motion, including when an Advanced Driver Assistance System feature is in use, causing loss of brake boost until the module enters sleep mode after the vehicle is turned off.
The problem can lead to increased stopping distance, especially during an ADAS braking scenario, thus the crash risk.
Ford said in a notice filed with the National Highway Traffic Safety Administration that the issue stems from the EBB motor’s potential for voltage disturbances and accompanying current surges that can temporarily exceed the module’s limits, causing shutdown.
If the problem occurs, the vehicle should issue a warning sound and instrument panel messages, and the driver should notice a change in the feel of the braking, along with increased stop distance.
Ford said it’s aware of nearly 40 warranty claims and one low-speed crash related to the issue but no injuries or fires.
The flaw will be repaired with an over-the-air software update or by a Ford dealer. The automaker is scheduled to mail recall notices to owners on Aug. 25.
