While driving at highway speed 70 mph electric emergency brake engaged without warning causing sudden and sustained loss of speed. Shortly after truck was pulled to the side of the road rear brake area was noted to have burnt odor emitting from the area. Further attempts to evacuate the vehicle from the roadway were unsuccessful as the vehicle rear wheels intermittently locked up while the truck was in forward motion.

Brakes have completely ceased working at random times. Three times total: The vehicle will be in motion (at varying speeds) and when brake is applied, the pedal goes all the way to the floor with little resistance. One time I was traveling at 55 mph on the highway and had to stop suddenly for slow traffic - I was forced to use the emergency brake. Another time I was traveling at approximately 20 mph approaching a red light and I had to use the emergency brake to stop. The third time I was decelerating and trying to brake to take a hard right turn and the brakes didnt work; fortunately the I was already at a reduced rate of speed and the hard turn in slowed the vehicle enough that I was able to make the turn. But the truck traveled through my lane into the oncoming lane of traffic. Thankfully no cars were waiting at that intersection.

While driving on rural Maryland road, complete loss of brakes without warning other than "low brake fluid" warning less than two minutes beforehand. No accident, fortunately. I understand that this is a known issue and that Ford has not issued a recall for this extremely dangerous defect. Dealer has said that it will rebuild master brake cylinder and brake booster, using manufacturer original equipment but cannot state reason or cause for failure, nor provide any assurance that failure will not recur. Please compel a recall, if that is within NHTSA power.

On 8-19-17 truck was moving at about 30 mph on a street, went to stop at a stop sign, brake pedal went all the way to the floor, truck would not stop. Released brakes, and tried again, this time pumping the brake pedal. Truck stopped this time. Continued on, brakes felt spongy but would stop and started feeling normal again. On 8-26-17 same scenario occurred. Dropped truck off at Ford dealership on 8-28-17. As of 8-31-17 dealership has not duplicated problem, found any fluid leaks and has not solved problem. Just a side note. My brother in-law has the same exact truck and experienced the same situation about a year ago. At that time the dealership replaced the master cylinder and has seemed to solve his problem. I have also googled this problem and it seems to be a problem with other owners. Some have had the master cylinder replaced. I suggested this to the service writer at the dealership, service writer has declined to replace master cylinder since they can not duplicate problem or find any leaks.

Just over 21000 miles on my 2016 F150. While pulling into a parking spot right after getting my truck washed, the engine revved and I had no brakes. Pushed brakes all the way to the floor again and again to no avail. Truck jumped the curb and smashed into the wall. Crash warning lights/ alarm did not go on and the airbag did not deploy, though the airbag light came on. Truck filled with smoke...but cleared out relatively quickly. Brakes seemed fine after that....in the shop now...see what Ford has to say.

As a Ford owner why was I not notified of possible brake issues with my F150? I was driving home from the airport on Sunday morning on the freeway when a light came on about brake fluid. I tested my brakes. They worked. I continued cautiously to my exit. For whatever reason (grace of god) I took my foot off the gas when I got off on the off the exit. As I neared the stop light and applied the brake, I found I didnt have any!!!! the E brake barely stopped me. Had I not decelerated when I did I would not have been able to stop! I could've been killed!!! when I called Ford they never mentioned any issues!!! I pull a travel trailer and had a trip planned this upcoming week. Had this happened then the outcome could've been horrific! how can I trust that once the vehicle is fixed it is safe" im afraid to take my grand kids in my car! how can I trust Ford when they weren't up front about the situation to begin with. Do we wait for fatalities before we do something? what's my recourse" I have always been a strong Ford supporter (my mom retired from Ford) but am extremely disappointed by Ford and by any and all agencies that govern notifications of such issues. I should not have to be web surfing to find out that there are issues. I have a brand new rig for a reason and am paying for it with the expectation that I can feel safe in my rig!

The truck just turned 10,000 and now the brake pedal has gone very soft and it requires pushing the pedal to the floor to get the brakes to activate. Gentle driving, regular service, not a fluid issue. This truck has the 2.7 ecoboost engine.

After owning this vehicle for 1 month, the breaks failed on me while I attempted to stop at a stop sign before pulling out onto a highway. The break pedal went straight to the floor and I rolled out into traffic instead of stopping. This is my main family vehicle, it is what I drive my 2, 3-year old children in 99% of the time. I looked for a recall status and found multiple complaints of this issue online, but no recall being issued. I am terrified to use the vehicle now and I am now stuck with it for a minimum of the next 6yrs till it's paid off. If this had happened while I was on a family vacation towing a 6000 pound trailer (what this vehicle is intend for in my family) my family could have been seriously injured or died! now I'm stuck with a $35K vehicle, not feeling safe taking our family vacations and my $17K camper just sits here unused because I don't have a safe vehicale to use for towing.

2016 F-150 platinum with 20K miles just had "low brake fluid" notice come on as I started pulling out of parking lot that was downhill and realized I had no brakes when the pedal went to the floor. I quickly used emergency brake to stop the truck and pull back into parking space. Pulled up the hood to find the reservoir was low. Pulled up good ol google and what do you know... its a common problem with the master cylinder. Glad I wasn't driving with my kids towing the boat going downhill. Off for repair.

While driving my truck I had total loss of brake function without warning. Further investigation showed the fluid reservoir was empty despite no evidence of leaks. I feel this is inline with the brake booster/master cylinder recalls of 2013-2014 year models. I suspect the brake fluid has been drawn into the vacuum booster. I'm awaiting dealership service at this time. I was on a mountain road and luckily we were on a level spot instead of on a hill.

- Rio Rancho, NM, USA

I experienced a sudden and complete loss of my brakes while backing out of my garage. When it happened it was instantaneous and I had no braking power at all. The brake light came on immediately and low brake fluid light was also on. The Ford dealer confirmed upon repair that the master cylinder dumped most or all of my brake fluid into the brake booster. They repaired the issue, but used the same factory parts my truck was made with. What's to say this won't happen again"?"
