Brakes fade, sometimes to floor on 2015 Ford F150 with 3.5 engine. No warning light or chime alet's the driver. 2015 models usually have a warning indication if this happened and 2016 models do not. Build date is Oct. 2015. The dealership can not find any problem with the brakes! these 3.5 models must be investigated and repaired!

My fiance and I were driving down the highway, with no cruise control on, and suddenly my sensors go off as if I was about to hit something. Then after a second (probably was only a split-second, but it felt like forever), it went away. If adaptive cruise control would have been enabled, this would have caused the brakes to automatically press (I know because this has happened to me before). I was passing a semi, if that helps. This is a very dangerous issue (sensors thinking they are going to hit something, when it should be nothing). I wish I had a video of it happening, but it only has happened 3 times for at most 3 seconds in the the 1.5 years I have owned the vehicle.

I just read an article about the brake failures on the 2015 & 2016 F-150. I have a 2015 F-150 platinum 4X4 with approximately 31,000 miles and experienced a similar event about 2 weeks ago. As I approached a stop signal on my normal route home, the brakes failed when I stepped on the pedal, it acted like the anti-skid brake system had taken over and wouldn't allow the pedal to apply hydraulic pressure to the brake calipers. This was the first and only time it has happened, so I did not report the event to Ford. No damage or injury occurred.

Had my boat trailer (9000lbs with electric/hyd breaks) hooked up, was trying to backup my steep driveway and the truck slid a bit forward in reverse and I tried to hit the break pedal but no action so had to turn quickly into the street to avoid an danger, was able to stop the truck on the flat street and low 4 wheel drive on. Stop the engine and tried the breaks and they were working fine. Did not think more about it until I saw this concern on the news and therefor a bit late reporting it.

- Shoreline, WA, USA

The contact owns a 2015 Ford F-150. While driving approximately 70 mph and upon slowing down to exit the highway, the brake pedal traveled to the floorboard. The contact managed to pull over to the side of the road and drove slowly to the dealer. It was diagnosed that the master cylinder caused the brake failure. The manufacturer was made aware of the failure and the master cylinder was sent to the manufacturer for analysis. The vehicle was not repaired. The failure mileage was approximately 9,600.

I was driving the vehicle when its diagnostic system reported "low brake fluid". I pulled into the closest gas station and checked brake fluid level. It was almost totally out, so I purchased 2 small cans and filled up brake fluid reservoir. I had just had the vehicle into the dealer for its scheduled maintenance, so it was odd that brake fluid was low. No external leaks were visible. I drove another 5 miles, and the diagnostic system reported again, "low brake fluid". I pulled into another gas station and rechecked the brake fluid reservoir. Again, it was almost totally empty. I could not detect a visible brake fluid leak, but could smell brake fluid in the engine bay. I parked the vehicle, and called the dealership to see if they were still open. They were about to close. I restarted the vehicle and the brake pedal went all the way to the floor. I called a tow truck and had the vehicle towed to the dealership. While attempting to park the vehicle in the dealer's lot, I had no braking capabilities. Dealer diagnosed the problem as a defective master cylinder. Repair was done by dealer by replacing master cylinder and brake booster. There was an approximate 30 day delay in repairing the vehicle because there is an existing recall on 2014 Ford F-150's for defective brake boosters, and Ford was back ordered on the parts. I just picked up my vehicle from the dealership and it was successfully repaired.

Brake pedal dropped to floor and significantly lost ability to stop. Mechanic says needs to replace brake master cylinder and brake booster. Parts are on backorder which indicates there is a problem - parts department said there are 700 on backorder and it will take over a month to get them

Low brake fluid light came on, with in one mile the brake pedel went to the floor with very little stopping power. Brake fluid resevior was completely empty. Added brake fluid as warning light recommended, drove 1 mile and brake fluid resevior was empty again. Luckly I was driving in town with very little traffic.

- Lewiston, ID, USA

I was driving to work at ~65mph during rush hour and the brakes failed. First a warning light about low brake fluid then followed immediately by complete brake failure. I was lucky and got to the shoulder and coasted until stopping. The truck has been at the dealership for almost a month (still don't have the vehicle back).

I was on my way to work one morning when I noticed my break pedal seems to be going lower than normal. After driving a little more it seemed to be ok. As I got about half way across houston, I was coming T a red light and when I hit my breaks they went completely to the floor and I went through a red light. Luckily it was so early that there was not much traffic. I called roadside to row my truck to the Ford dealer to find that this seems to be an ongoing issue with trucks around this year model, and the master cylinder is on recall until (hopefully) Aug, 22. That's is a full month without my truck. There has currently been no recalls on these models, but if there is not one soon, someone is going T get seriously injured or even killed with this default. ( I only have 5600 miles on this truck by the way).

Driving on interrstate 70 at 65 mph, I had several alerts begin flashing ranging from check 4X4, hill assist failure, 2H, parking brake and many more. In addition I lost power steering, brake lights and turn signals. I was able to drive truck home. This happened 4 more times. I called dealer and they suggested I drive it to their establishment some 20 miles away. I did not feel safe and contacted roadside assistance to tow the truck. I had to beg for a loaner one week later I received a call stating the technician needed to drive the truck to see if the same alerts happened even though they found 12 plus alerts when they analyzed the truck in their shop. I allowed this to occur as I wanted answers. I received a call today stating they had found the problem, a wire had became corroded in the steering column causing all the alerts to malfunction. They are replacing the entire column and my truck will be completed by Tuesday. I had purchased this truck just 4 months prior and have been a loyal Ford customer for 30+ years.

My girlfriend and I were driving down the highway on a sunny day at around 70 mph. I was using adaptive cruise control. There were other cars on the road, but none within distance to affect my speed/cruise control (they were all way ahead or behind). All of a sudden, for about a half second, my truck flashed the warning light and sound as if I was going to hit something, and it automatically pressed the brake for me. It was very scary and dangerous. Then it came out of the warning and we continued on our way (we were in a bit of shock). I of course turned off the adaptive cruise control so the vehicle was under my complete control. Thinking back, I'm wondering if the shadow from an overpass caused my truck to think there was a vehicle close and an impending crash. Either way, it was very unsafe, and I'm hoping it doesn't happen again to me, or anyone else.

While on vacation and towing a 16' enclosed trailer the trailer brake control module (tbc) failed. While driving, failure was temporarily indicated by a momentary winking off, then back on, of the tow haul mode indicator. No trailer brake control failure code was given. The vehicle was able to continue to the next stop at which time it was turned off. After re-starting and attempting to leave, the trailer brakes were fully locked. After removing the electric pigtail connector the trailer brakes released and it was taken to a nearby rv dealer where it was determined the fault was with the vehicle not the trailer. The vehicle was then taken to the nearest Ford dealer were it was determined the trailer brake control module had failed. The dealer indicated the part was on back order for several weeks, at which time it was determined the best solution was to install an aftermarket unit which was done so the following day. Although the vehicle is still under warranty, neither Ford nor the dealer would cover the cost. Failure of the tbc at highway speed may cause the trailer brakes to lock, causing serious damage or injury. This seems to be a recurring problem as indicated by the back ordered part and noting several threads regarding the same issue on the F150 forum. www.F150forum.com/F82/2015-integrated-trailer-brake-controller-malfunction-308674/

Complete brake failure. Brake fluid low level light illuminated while driving a very busy road and within 2 minutes the master cylinder had depleted all fluid and brake pedal was going all the way to floor board. Luckily the wife was able to get the truck into a parking lot unscathed. Truck has been at dealer for a week due to master cylinder being on backorder. Apparently the issue affecting 2013-2014 F-150S is also affecting 2015S as well. Truck has approx. 15K miles.

Brakes went out while driving. Pedal went completely to the floor. A warning light came on indicating low fluid. I took the truck to a local garage and they determined that the master cylinder had failed and also brake fluid had looked into the booster. The brake fluid reservoir was completely empty. The vehicle had been parked for a few days. We drove the vehicle 5 miles without issue. Vehicle was towed to nearest Ford dealer nearly 40 miles away. That Ford dealer has failed to begin repairs, claiming they are busy and consequently it will take 4 or more days to repair. We are 12 hours from home and stranded by this new pickup. This is precisely the same issue as raised in the complaint with NHTSA id number 10873438
