Vehicle was in motion on the freeway nearing speeds of 65mph when the break light came on and indicated low break fluid (prior to the alert my breaking system was functioning normal) my breaks completely gave out, and I depressed the break petal as far as it could go only slightly slowing my vehicle and relied on my parking break to come to a complete stop. After towing it to an official Ford repair shop, the diagnostic showed a failed master cylinder, which leaked break fluid into the break booster causing the whole system to suddenly fail putting my three year old sons life in danger as well as mine

The check brake light turned on. The brake fluid reservoir was empty. Refilled and drained immediately with no visible leaks from system. Pedal could be pressed to floor without activating brakes. Mechanic determined that master cylinder was defective and leaking into booster.

Master cylinder and booster total failure. Thankfully this happened in my driveway before heading out to dinner. Brake pedal traveled all the way to floor. Master cylinder reservoir totally empty. No signs of any leaks or fluid on the ground. Had it towed to Ford dealership for repair thinking it would be covered by the Ford cpo power train warranty. Service advisor said this is the first time in 15 years he has seen a master cylinder fail on an Expedition. I agree with other owners this sounds very similar to the issue Ford had with the 2013-2014 ym F-150 pick up trucks with the 3.5L ecoboost engine.

The contact owns a 2016 Ford Expedition. While driving 40 mph and making a turn, the brake pedal was depressed and traveled to the floorboard. The contact could not stop the vehicle. When the contact pumped the brake pedal, the vehicle stopped. Also, the brake fluid warning indicator illumined. The vehicle was taken to an independent mechanic, but was not diagnosed or repaired. The contact called a Ford customer service line and was informed that the brake cylinder was fractured and was leaking brake fluid. The vehicle was not repaired. The manufacturer was made aware of the failure and provided a case number. The dealer was not contacted. The failure mileage was 50,450.

Brake fluid warning light came on while taking daughter to school, stopped at gas station to check. Was almost completely empty. No visible sign of leaks in engine compartment, under vehicle or on wheels/tires. Refilled. Warning light came on mile later. Stopped at another gas station, almost completely empty again. Bought more fluid, refilled and attempted to drive home. About a mile later warning light appeared again. Once home, brake fluid level was empty again. Looked on-line and noticed there was a recall on 2015 F-150 trucks for the exact same issue (master cylinder failure, leaking fluid to brake booster). Refilled then attempted to drive to dealership. Stopped once to refill after warning light came on again. Got to dealership and as pulling into service bay brake pedal had no pressure, went to floor and vehicle would not stop. Luckily, was just rolling slow and was able to but vehicle in park to stop. Very dangerous if this had occurred on street! Ford dealership confirmed suspicion, master cylinder leaking in brake booster. Same issue as 2015 F150 recall, but there is no recall for 2016 Ford Expedition even though they use the same drivetrain? vehicle out of warranty so had to pay out of pocket.

Catastrophic brake failure during normal operation on a city street I was able to safely stop due to a low fluid light but by the time I was at a safe place to stop the brakes had almost completely failed. I had to be towed to dealer. Was told the master cylinder, brake booster, valve assembly, and vacuum brake sensor all needed to be replaced because the mc was leaking into the brake booster causing them to fail. This is the exact issue that the 2013-2014 F150S (very similar platform) had a recall for. Https://media.Ford.com/content/fordmedia/fna/us/en/news/2016/05/25/Ford-motor-company-issues-one-safety-recall-and-one-safety-compl.html service tech stated the mc had likely been leaking for some time to cause the failure. I had the vehicle in for routine maintenance at the dealer which included a full brake inspection which was given a clean bill of health less than one month prior to this failure.

Wife was driving home from work when the "low brake fluid" warning light came on going 45 mph. Less that one minute later when she went to stop and the brake pedal went to the floor and the vehicle would not slow down. Thankfully she was going up hill and able to get the vehicle to stop safely. Checked the brake master cylinder reservoir and there was no fluid in it. Checked the brake master cylinder for visible leaks and did not see any fluid.

- Hawthorne, NY, USA

Approximately 21000 miles, sudden and complete brake failure while driving the vehicle. A warning message was displayed on the dash "low brake fluid". I touched the brake pedal and it depressed completely to the floor. I inspected the vehicle, no visible leaks at any of the wheels or in the engine bay. Brake fluid reservoir was empty. Refilled reservoir only to watch it drain with no visible leaks (into the booster?)

Brake failure. 2016 Expedition ecoboost, car notification of 'low brake fluid'. even after adding brake fluid purchased from Ford dealer; the fluid keeps decreasing all without any visible leakage around car and/or tires/etc. Eventually and quickly you will quickly get zero brake response; the brake pedal will go to bottom of floor and in my case; there was white clouds coming out of our exhaust. Zero braking ability. We had our vehicle parked on a flat parking lot and after checking the fluid, after filling it up; turned car on; had emergency parking brake enabled and then putting it in drive; just to test brakes; the car rolled but zero ability to brake, thus reapplied parking brake to control vehicle to a stop. All while engine appears to sound ok; with an occasional 'stutter' while white smoke comes from the tailpipe.

Was diagnosed with a damaged master cylinder that leaked into the brake booster and had to be completely replaced.

The contact owns a 2016 Ford Expedition. After the vehicle was started and the accelerator pedal was depressed, the contact experienced unintended acceleration even after the contact depressed the brake pedal. As a result, the contact crashed into a pine tree. The vehicle remained at full acceleration until it was de-powered manually. There were no injuries and a police report was filed. The vehicle was towed to a dealer, but the diagnostic results had not yet been determined. The manufacturer was not notified of the failure. The failure mileage was approximately 35,000.

- Hot Springs Village, AR, USA

Leased car 11/2016. On 1-6-16, complete loss of brake power, no warning, no warning lights. Sudden. Avoided collision. Dealer found vacuum pump failure, fixed. Then happened again 1 month later 2-2-16, again accident avoided. Brake pedal went to floor w/O any pressure. I am told by cust service that they found same problem. They are trying make us take car back. We are concerned that braking system flawed and car unsafe. We refuse to accept car back. Broiled in debate between cust service and dealer. Dealer trying make us financially responsible for defective breaks, and claiming lemon law requires 4 events.

My 2016 Ford Expedition el ltd V-6 3.5L with 354 odometer miles produced 4 minor Prelude engine surges within a couple hours on the roadways before it went full throttle 5 times within a couple minutes. It suddenly, and without warning, ran down my wife after squishing her against the garage-bedroom wall (which was destroyed) in reverse, placed me in traffic danger when it raced out of the driveway, placed a witness driving in the street in danger as it backed up, and while turning into my driveway forward, plowed half its length into a neighbors house, and destroyed most of its exterior as a result of the forward and reverse collisions. The brakes were absolutely useless and could not begin to overpower the individual engine full power surges. The air bags never deployed despite the frontal impact exceeding 15 mph. The full throttle engine surge durations approximated 6 seconds each; and, the temporary returns to idle lasted 2-4 seconds. My wife is quite injured; but, could easily have been killed. I was planning a head-on large oak tree ramming to stop the vehicle once-and-for-all. Other people and Ford need to be advised of this potential death trap situation. Please help.
