. last Sunday I got a 2017 F150 XLT stuck in a small two foot snow drift. Once I got stuck I tried rocking the truck, but the transmission would not shift from forward to rear ward without the truck coming to a complete stop. After several attempts I got a fault warning for the limited slip diff. The warning for the power steering, the ABS, the parking brake, the hill descent, hill start assist, park assist warning (which I do not have), advanced track warning (which I do not have) and 4X4 low. Additionally the truck would shift in and out of 4 high, but not 4 low. In 4 high no tires would move. In two high only the left rear tire would spin. Because of darkness and grizzly bear I had to wait until morning to walk out far enough to get cell reception. The temp never got below 34 degrees, but it did rain and snow all night. When the tow truck pulled me out of the drift (a total of 10 feet) everything except the power steering worked. It was not until the 3 rd day when the power steering suddenly started to work. The dealer will not see me until next week and I am afraid I will loose all the fault codes by then. Its great to have a 4X4 that only works on dry ground. Had this happened in the winter or further away from cell phone coverage it could have proven to be a life threatening situation

Brake pedal must be pressed at least 1 1/2 to 2 inches for braking to begin. At this point the brakes are not firm. Also, while on a downward grade or hill the brakes initially brake, but slowly lose pressure and have to be pumped to retain braking. I have taken my truck to dealership 4 times and was told that this common to all lariat trucks and they cannot repair. Obviously, this is a defect that Ford should address immediately.

No break lights, backup lights, parking lights, turn signal lights in rear.

Sudden loss brakes in a hard stop. There are videos explaining the problem where the ABS unit goes into bypass and for one wheel; but then the value does not reset. This issue has happened to me 4 times while driving the car, and to my wife once. Taking out the ABS fuse, and thereby disabling the function solves the problem, as the bypass valve will not engage. However you lose the mandated feature of ABS. Detailed explanation found at https://www.youtube.com/watch?V=0R46_unyyk8. This started at 7,500 miles and continued until I disabled the feature when Ford could not isolate and fix the issue.

While applying the brakes, it is very easy to simultaneously push on the throttle pedal. This has happened several times, one time resulting in a rear-end collision, this is my first Ford and this problem has never happened in any of the numerous vehicles I have owned. I had thought that software was in place that would not allow the engine to rev with the brake applied. If not so, it would seem like a very good idea.

When I come to a stop the brakes will be firm and the go soft and go all the way to the floor. Also when I press the brakes I have to pump them so they will work. When this happens I'm either at a stop sign or a stop light. Its also happened when I'm coming to a stop. The worse part it happens separately and the dealership thinks I'm crazy.

I was shocked at the number of F150's on the web with brake pedals suddenly going to the floor during all types of stopping situations. The problem seems to span 2016-17 models regardless of engine. It started yesterday with a freeway off-ramp failure and put me in the middle of a relatively safe intersection today... no brakes. I've seen master cylinders replaced to dealers stating that is the normal operation. That last part is pretty lame... brake pedal going to the floor? the brake initially seems to work and then the pedal sinks slowly to the floor with no braking force at that point. At a full stop in park, I can repeat the failure. Touch the brake and it appears to be ok. Quickly touch it again and it immediately sinks to the floor. Apparently knowledgeable dealer indicated that there may be an ABS solenoid sticking cycling brake fluid back to the reservoir instead of being applied to brake pressure. This sounded much more logical than replacing the master cylinder unless the ABS is integrated into it in some manner.

Master brake cylinder went out at 6,267 miles- brake pedal went to floor while at intersection- was able to pump up - had to pump up every time vehicle was shut off and failed once after pumping up at traffic light

- Saginaw, TX, USA

I got in my truck and started driving. As I approached the intersection I started to brake. The brakes went all the way down and the truck did not brake. I ended up past the stop sign in the middle of the intersection. I turned around and went back slowly to my house. I almost hit a pedestrian where the truck did not brake.

- Pecos, TX, USA

I was coming up to a stop light and applied the brakes. The pedal went to the floor and the vehicle was not stoping. I released the brake pedal and pushed it again. This time the vehicle stopped. I immediately pulled over and checked the brake fluid and it was full.

There has always been a "brake light" sign turn on inside dashboard, and the brakes do not brake while it is in motion. When I step on the brake pad, the pad goes all the way in but does not stop my vehicle at all. It works sometimes, but my stopping is not guaranteed every time. Also, when I am at a red light, my engine is supposed to shut down then start back up once I release the brakes (2017 F150). However, my engine does not shut down at all. I have been to the dealer a few times and had my vehicle serviced, however, nothing has changed. Now, my dealership is avoiding me by not picking up my phone calls. I am afraid to drive on the road with this vehicle for my safety, and the safety of others.

The vehicle was bought brand new in corpus christ, tx back in April 2017. August 26, 2017, I was on my way to Colorado and realize my break pedal would go all the way to the floor and suddenly lose braking ability simultaneously, which would be a disaster if an emergency brake is necessary in some situation. Fortunately, it happens when I was on a parking lot trying to get back to the main road from a short break. I did not take it very serious as there is only about 4500 miles on the truck, and the brake did function okay when you need to slow down on highway (I mean slow down, not to make a stop), but not until I almost hit a pedestrian in the neighborhood in denver. After that, I had to be very very very very careful whenever I need to perform a brake since I realize it was extremely difficult for the vehicle to make a complete stop even driving in neighborhood at about 25 mph. The brake pedal would go all the way down even when your transmission is at park. So I cancelled everything I planned in Colorado and stayed hotel for 2 days until corpus was cleared from hurricane hazard. I drove the vehicle back very very very very carefully and sent it to the dealer the next day when I got home, which was Thursday August 31, 2017. The tech identified the problem as master cylinder failure and got the master cylinder ordered and replace on September 8, 2017. I understand the dealer is very busy because of the hurricane, and I do appreciate the they manage to give me a loaner vehicle Taurus to drive. However, the master cylinder did not fix the problem according to the tech and they have to order and replace the hydraulic control unit, which would take another 10 business days. I did some research online and saw other people having similar problems. I hope Ford, if not, NHTSA could take this issue serious before someone got injured or killed due to this problem.

On 08/07/2017 while traveling approximately 55 miles per hour on highway 281 in san antonio, tx my 2017 Ford F-150, V8 super crew, 4X4 ftx experienced complete brake failure. My brakes went to the floor with no brake activation and I had to swerve to the left two lanes to avoid impacting the vehicles in front of me. Once on the shoulder I had to pump the brakes in order to stop after travelling several hundred yards. There was absolutely no warning (noise, service lights, etc.) prior to, during or after the brake failure. The vehicle was only four months old with 6400 miles on it. If there was no shoulder or clear lanes it would have caused a severe accident likely resulting in injuries. I was able to slowly and carefully make my way to the dealership on side roads but experienced total brake failure three additional times. The first time was while I was stationary at a stop sign facing slightly downhill my brake pedal went completely to the floor and I had to pump it several times to make the vehicle stop again. The other two times I was traveling approximately 25 miles per hour and missed my turn (right) and proceeded past the turn approximately 50 yards and had to pump the brakes in order to stop. The dealership had to remove and replace the master brake cylinder. They indicated it was leaking internally and gave no explanation why a service light or other warning did not come on and there is no current recall for that part.

The brakes went completely out. They replaced the master cylinder, upon getting it back the brakes failed to stop adequately, and it was returned at that moment. They "bled the brakes" again and returned it. There was only 1 work order for this. The truck sat for a week and not the brakes are soft and inconsistent. I returned it to Ford and they stated it was working as expected; however in a panic stop the brakes failed to do more than 50% stop effort and on another occasion I pressed the pedal to the floor, and had hardly any brake. I took it back to the Ford dealer and they said there was nothing wrong. Since they did not take it in for service there is no record of this third attempt to get the brakes fixed. I then called the Ford customer service line and their answer is just to take it somewhere else. This vehicle is dangerous and it falls outside the recall notice for a replacement master cylinder. However that is the initial failure. I suspect additional issues; but Ford is failing to address them.

- Frisco, TX, USA

I was driving and when I need to make a hard stop, the brake pedal went to the floor. I had to use the emergency brake to help slow me down. While there is some braking, if you are stopped and push hard on the brakes, the pedal goes to the floor.

- Irving, TX, USA

While driving at 35mph, the low brake fluid warning light came on. Within 200M while trying to slow, brake pedal went to the floor with complete and total loss of braking ability. While using emergency brake, large puff of smoke came from exhaust

- Houston, TX, USA

The vehicle will not stop completely sometimes. Other times, the brake pedal is all the way to the floor before the vehicle will cease movement. No matter how great or how little pressure is applied to the brakes the pedal will go all the way to the floor.

- Baton Rouge, LA, USA

Purchased vehicle about 2 months ago. This morning I was slowing the vehicle at a stop light. Once pressure was applied to the pedal it would continue to progress all the way to the floor. Checked brake fluid and it was full. Problem persisted so vehicle was taken to the dealership.
