THE BRAKE SYSTEM WENT OUT WHILE DRIVING MY 2017 FORD EXPEDITION ON THE FREEWAY. THE WARNING LIGHT CAME ON INDICATING LOW BRAKE FLUID. WAS ABLE TO SLOWLY MAKE IT TO THE NEAREST SERVICE STATION, AS BRAKES COMPLETELY FAILED, PEDAL TO THE FLOOR. AFTER SOME RESEARCH THERE IS A RECALL ON THE MASTER BRAKE CYLINDER AND BRAKE BOOSTER SYSTEM ON THE F150 ECOBOOST. NHTSA CAMPAIGN NUMBER: 20V-332. FORD'S REFERENCE NUMBER FOR THIS RECALL IS 20S31. 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.

Aug 11, 2021

Brake master cylinder failed causing brake fluid in the brake booster and little to no breaking at freeway speeds. There is a current recall on same model year F150 with the same 3.5L eco boost engine manufactured out of the same plant as our expedition. Took off the master cylinder and the brake booster was filled with brake fluid. SUV has aprox 67k miles.

Jul 9, 2021

Brakes failed while driving. Mechanics found all brake fluid leaked internally from master cylinder into the brake booster. I have another Ford vehicle that was recalled for this exact problem in 2017.

Jun 14, 2021

Wife started car. Pushed on the brake to put it in gear. Brake pedal went to floor. Checked master cylinder. Cylinder was completely empty. Brake fluid leaked past seals in master cylinder into the brake booster, then got sucked into engine and burned. No warning lights came on at all.. Luckily wife was at the pool down the road from our house when it happened. She drove 5 mph back to the house. A four year car should not have a faulty brake master cylinder. Master cylinders should last for at least 10 years. Ford has a major problem brewing.
