My truck is a 2016 F150 with 4053 miles. The vehicle has a 5.0 V8 and 7 weeks after purchasing the vehicle new, the master cylinder failed. The vehicle was in motion on a city street and the signal light turned red. I depressed the brake pedal and it went all the way to the floor and was not stopping, only slowing. I downshifted the automatic transmission and pumped the brakes before finally stopping. This occurred without warning. I immediately drove to a Ford dealer less than 2 miles away and they confirmed it was the master cylinder which of course is not in stock. After doing some research, earlier models have had the same issue. Apparently, Ford has not corrected the problem. This is a safety issue that needs immediate attention!

2.5 month old truck with approximately 7K miles driven. I was rolling down a hill about 10mph and tried to stop to talk with a neighbor. The pedal travel didn't feel normal and I rolled about 5 feet past my neighbor. After coming to a stop the pedal slowly sunk to the floor. I shifted to park then released and reapplied the pedal. There was initial resistance at roughly the normal pedal height, and again the pedal slowly sank to the floor. When I shifted back to drive and tested the brakes I experienced a slightly diminished "initial grab" when applying the brakes which then would decrease even further while the pedal sank to the floor. When the pedal was completely depressed I had very very little braking ability. Ford has had the truck for over 3 weeks and states that they believe the master cylinder to be faulty and the lead time on a replacement is quite long. (3 weeks they hope). I have spoken with Ford customer service and opened a case. The told me they would seek to prioritize the part for me. I have not heard from them (were supposed to call last Thursday) dealer has no updates for me either. In view of the recall for previous year F150 trucks for brake related issues that are identical to what I have experienced, I am not comfortable towing with this truck...assuming it is actually fixed any time soon.

Brand new king ranch Ford F-150 brakes recurrently fail. No accident but they currently have greatly reduced stopping power, super dangerous. Ford reports long back order 3+weeks on master cylinder, makes me wonder if there is larger issue.

6,500 miles on new vehicle and brakes completely failed, no accident to report

Brakes completely fail, when I pushed the brake pedal down. It went straight to the floor with no resistance. This has happened 4 times. Sometimes pumping the brakes helps. The emergency brake was used to stop the vehicle 2 times. Once a sharp swerve off the road while pumping to stop. The last time I coasted to a stop. There seems to be no matter of speed, type of stop or incline in common. Except the vehicle is in motion and the brakes won't work. I'm waiting for a tow truck right now

The pickup truck is no older than 3 months and while driving on the expressway I suddenly lost function of my brakes. The brake pedal went all the way down with no brake reaction. The midway Ford dealership informed me the master cylinder brake was defective. Thankfully no one was injured, nor any physical damage to property; however the traumatic incident did cause me angina due to my heart condition. I was extremely lucky to have been able to have controlled the health condition with nitroglycerin. All I ask is that Ford take this incident seriously to avoid any future accidents which may potential result in a fatality. I no longer have faith in my vehicle and prefer a different car moving forward.

Adaptive cruise control braking issue. My new 2016 Ford F150 platinum edition pick up truck will automatically brake hard when passing some large trucks while operating in adaptive cruise control. The lane ahead of me was clear with no vehicles in sight in my lane each time this happened. The large trucks I passed were on my right and not in my lane or even close to the lane markers. The large trucks did not have anything hanging over into my lane. These dangerous braking events happened while I was driving on very good dry highways and freeways in Arizona. I have no stickers or after market items on my new F150 truck. This hard automatic braking happened to me on four different occasions during the month of March. In each of the four braking events I was traveling between 65 and 75 mph on straight high quality roads in Arizona. I was almost rear-ended the last time it happened so I'm no longer using cruise control. As of today 4/8 my truck is at the morgan hill Ford store in morgan hill calif for inspection of this dangerous problem.

While in park with the driver door open, truck off, radio on, confirmed shifter was in park position. I accidentally engaged manual transmission control in front of and gear selector at thumb position of shifter as both are unavoidable. As I was getting out to reach something in the back seat, truck released park and rolled away. In addition, while driving in D (drive) thumb accidentally made contact with (-) control and quickly decelerated to a quick stalled stop, beginning at 50 mph down to a stop in the road in less than one quarter of a mile. M (manual) selector is an option on the panel, however, both these events happened while in P and D, respectively. In park the truck was in a stall and stopped. In D the truck was traveling at 50 mph. This is a software malfunction that is allowing an override of braking while in park and rapid shifting at the touch of one control that sits under the drivers thumb.

My 2016 F150 has adaptive cruise control ("acc") that applies brakes in the event a vehicle is detected in lane ahead in order to match speed and maintain safe distance. F150 also has collision avoidance system that increases sensitivity of brakes if imminent collision is detected. 2015 Ford F150 has been subject to a recall (NHTSA campaign number: 15V614000) to fix problems with acc - the acc may falsely detect an obstacle in its path and may unexpectedly apply the brakes increasing the risk of a rear-end collision from a following vehicle. My 2016 F150 was built after the date covered by the recall however it exhibits the exact problem described in the recall I.e. the problem continues to exist with Ford's acc system and the recall was insufficient. In my case, on four separate occasions from 3/19 through 3/26/2016 the acc system activated unexpectedly and for no reason, causing heavy braking and in one case almost causing collision with a following vehicle. The collision warning lights also lit up - this system may itself have increased severity of braking. Braking events occurred with two different drivers, on straight freeway, no steering input, no bridges, or safety barriers to confuse the acc radar. In all cases we were driving in left lane of a two lane freeway, approaching to pass a large vehicle travelling in right lane - a semi-truck in two cases, empty car transporter in other two. The vehicle being passed was well in its lane and not drifting over or presenting any danger to our vehicle. Ford's response has been that this is "normal" and was due to our driving on a curve, or other vehicle drifting over or some road "furniture" like a bridge / barrier confusing the system. However, none of these factors applied.
