Ford has a problem with brakes on over 100,000 F-150 pickup trucks, Expeditions, and Lincoln Navigators. It affects older vehicles from 2017 and 2018, and it could lead to reduced brake function. If left unchecked, it could ultimately lead to brake failure. Since that constitutes an obvious safety risk, Ford has issued a recall.
The recall number from Ford is 25S37. It applies to 87,738 F-150s, 30,200 Expeditions, and 5,673 Navigators, all from the 2017 and 2018 model years, and all equipped with 3.5-liter EcoBoost engines. In total, 123,611 vehicles are covered under the recall.
The problem lies with the brake master cylinder. A leak could develop from the master cylinder front wheel circuit, allowing brake fluid to enter the brake booster. As fluid leaks over time, brake performance could diminish. Lose enough fluid and the brakes will stop working altogether. Drivers should feel a very soft, spongy pedal before things get that bad. Also, warning notifications on the dash should warn drivers of a problem with the brake system.
The good here is that, as of now, Ford is unaware of any accidents or injuries resulting from this problem. The issue came to Ford’s attention in January 2025 courtesy of the National Highway Traffic Safety Administration (NHTSA). Documents at the NHTSA reference a Vehicle Owner Questionnaire about fluid potentially leaking from 2017 Expeditions. The issue went to Ford’s Critical Concern Group in February, which investigated through February and March. Elevated warranty claims were found for Expeditions and Lincoln Navigators, but curiously, the F-150 didn’t show a similar trend.
In any case, Ford will replace the master cylinder on recalled vehicles. The automaker will also replace the brake booster if there’s evidence that fluid is leaking from the master cylinder. Naturally, it’s all at no charge to vehicle owners.
Dealer notification for the recall is already underway. Specific owner notification will begin April 28.
