Got in the truck in the morning, the truck was cold was backing up and pushed the break pedal and did not have breaks..this has happened twice to me.once in November of 2015 and February of 2016, when I called my wife to ask for the VIN# to fill out this report she said it has happened to her also 3 times in the last month.no breaks.in the morning, we live in Michigan.
The contact owns a 2012 Ford F-150. While driving approximately 40 mph, the brake pedal was depressed and traveled to the floorboard without warning. The vehicle failed to slow down and crashed into the rear of the preceding vehicle. The ABS activated even though the road surface was dry. The vehicle resumed normal operation, but the brake warning indicator was illuminated. There were no injuries. The front bumper sustained minor damage. A police report was not filed. On five separate occasions, the failure recurred. The vehicle was not diagnosed nor repaired. The manufacturer was not notified of the failures. The approximate failure mileage was 75,000.
After having the brake pads replaced at about 24,000 miles, I was backing up and lost power and almost ran into my neighbors yard. The mechanic is saying its the vacuum assist pump and possibly something else but this problem didn't happen before and only when I start the car and back
On start up the power brakes can fail to work resulting in extreme difficulty in stopping the truck when backing up our of the driveway or a parking space. This has resulted in two near miss accidents with parked cars in a parking garage. The issue appears to be limited to start-up for now. If you start the engine and let it run for a few minutes, the brakes appear to pressurize and work fine. It has not occurred while driving at speed. There is not indication of any braking issue with the onboard display.

Vacuum assist pump is failing at 33000 miles. This is the second pump that has failed.. pump makes loud noise and vehicle loses braking ability brake pedal requires excessive force to stop vehicle and greatly extends stopping distance.
Each morning, when I pull the truck out of the garage, the brakes sometimes do not work. Sometimes, it is very difficult to stop the truck. I heard it might be a vacuum issue, but it happens all the time, summer winter, etc. Truck was stationary to begin with. The brakes sometimes make a loud noise, as well. It's happened ever since I bought it, last year.
Periodically lose brake power and it sounds/feels like the antilock brakes are kicking in. Typically happens immediately after starting and at low speeds (<5mph). Brake power is returned if I rev the engine in neutral or park. Nearly hit a person in the parking lot and did minor damage to snow fence today when backing up and could not stop in time.
The contact owns a 2012 Ford F-150. The contact stated that while driving at approximately 35 mph, the brake pedal was depressed but the vehicle failed to stop. The contact veered to the right to avoid crashing into the vehicle in front and crashed into a tree. The air bags failed to deploy. The contact sustained unknown medical injuries that required medical attention. A police report was filed. The vehicle was towed to a dealer for diagnostic testing. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 39,000.
I have been hearing a loud noise behind my headlight on the drivers side for quite some time now. A few months back, my brakes didn't seem to work correctly and I rear ended someone. I am going through brake pads like crazy on my truck and my brakes still don't seem to work correctly. I was doing research and found out about the vacuum brake assist behind the driver side headlight. That's what's making that noise inder my hood & has got to be the problem for the loss of my brakes. If my brakes worked correctly I would have never rear ended car in front of me. I knew something was wrong at that point. & now I know the exact cause. But with everyone having this issue with the 2011-2012S, I think this is something that should be a recall. Ford should be the one paying for the wreck I got into since it's a common problem that's happening. Hopefully we could come to a conclusion before someone gets killed! I do have an accident report if you need more information from it.
At cold startup, the electric vacuum pump fails due to corrosion and the brakes do not work at all. The truck will not stop regardless of how much pressure is applied to the pedal during the first 2 minutes of startup time. This happens every time the vehicle is started after not running for more than 5 hours. I have nearly hit pets, kids, pedestrians, and mailboxes because of this. Parking attendants driving my vehicle have hit other vehicles because of this. This happens when the vehicle is first started, and immediately put into gear, it begins to move with no ability to use the brakes.
The contact owns a 2012 Ford F-150. When the vehicle was started, the brake pedal was depressed but failed to respond. The vehicle was taken to a dealer where it was diagnosed that the vacuum pump and wiring harness needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 67,000.
I have had continuous problems with braking after cold start when backing or driving forward out of my driveway. Replaced vacuum pump as this is a documented problem and after only a few days the problem resumed. This has been happening for several months. My truck is currently at my mechanic for further evaluation and potential repair. This is a serious safety concern and also costing me alot of money in repairs! I have not experienced any issues when driving on the roadway, however, I do not Transport my family in the truck due to this issue.
The below problem has repeated itself more than 20 times since the first incident. When parked overnight or over a long period of time, upon starting and operating the truck - either reverse or drive - the brakes fail to engage the first one or two times. Had to either hit the brakes very hard or I had to revert the truck to P(parking) position. This just about works to bring the truck to a halt, but even this failed a couple of times when D(driving forward). Thankfully, no one was around for 10 meters. This has led me to only starting the vehicle when there is no person/object either in front or the rear. It is high-risk each time given the damage the truck can do if it collides into something. It is not readily reproducible as it works fine thereafter and hence could not prove it exists to Ford technicians. Reported it first to Ford along with an E-brake issue on 02/12/2015. They replaced the E-brake but brushed off this issue saying it could be rust and it's normal on vehicles parked for long. However the frequency has increased of late and I see quite a few Ford owners having the same issue on Ford forums. The possible issues could be the vacuum pump failing, but Ford technicians claim to have never heard of this problem. Really at a loss and hope Ford sends out a bulletin to fix this asap. This is not a joke. It's life threatening and could cause real damage very soon.
When I started the car in the driveway and tried to move it 20 feet away from my garage, the brakes would not immediatly work and I came within 2 feet from hitting another car. I took the vehicle into the Ford dealership and they informed me that I had a brake vacuum pump failure and I had to pay $900 to have it fixed. If there were a child walking in front of my vehicle, I would have not been able to stop.
When vehicle is started with a foot on the brake, and then put into gear, the brake pedal depresses completely and the ABS system then kicks in to assist in stopping. The result was that there was a defect in the brake system's vacuum pump, which also blew the fuse for it. Under my extended warranty, the dealer replaced the vacuum pump, although not the fuse which caused a subsequent trip to the dealership as the problem did not seem to have been resolved.
Loss of brake pedal when parked at cold start. Able to eventually pump brake pedal to achieve vehicle braking. Problem occurs intermittently. Reported to dealer on 10/28/2014 but no problem found. Reported to dealer again on 8/19/2015 for further investigation.
2012 Ford F-150 ecoboost came off warranty in April, on July 2nd I started the truck, put it in gear (drive), and had no brakes. There was a grinding noise as if the ABS was trying to engage. I had to practically stand on the brake pedal to stop the truck and put it back in park. Pumped the brakes a few times and tried it again same thing. I shut off the engine, turned it back on, and let it warm up a few minutes. Now it was ok. From then on when the truck started cold it has done this on a regular basis. Good thing I found this before I reached any speed, and while there was no cargo in the bed to add inertia. I did some research and reported to Ford that the brake vacuum assist pump was likely corroded, and that this was a known issue on 2011-2013 F-150 ecoboost models. They needed a Ford technician to make the diagnosis, which I was charged $100 for (to determine that I was right). They also reported a bad fuse for the pump. I am hoping nobody is trying to say that with a bad fuse these pumps will disintegrate in three weeks of summer weather? let's be honest- the bad pump took out the fuse, if the fuse was blown. They estimate a ~$900 repair. I opened a ticket with Ford Motor Company because this event exactly matches NHTSA preliminary investigation item PE15026. People with these trucks or anyone around them could get seriously hurt if the driver cannot react quickly or panics when this part fails, and it is a poorly designed part. Apparently this part was re-engineered for 2014 and later models. At the time of this writing I am hoping I can get some help from Ford. I am a long time customer and have had no prior issue with the dealership or their service department. This is a manufacturing quality issue, pure and simple. I just wanted to report in order to make sure that this case was included with the others related to PE15026... updated 09/30/15
