This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
The brake fluid light came on and the brakes stopped working. There was no sign of a leak. I filled the master cylinder 2 times within 2 miles and samething continued to happen. I was able to slowly get it to a dealership and it was the booster and master cylinder. No signs of leaks. Immediately stopped functioning.
Riding down the road low brake fluid light comes on and brake light pull over put 24 oz. Brake fluid in drive for 20 miles hi-way same thing pull over master cylinder almost dry. Refill check vehicle for leaks nothing drive 1/2 mile check fluid down half way take truck to dealer say, S master cylinder leaking into booster pump luckily driving early morning no traffic and was able to pull off road quickly could have been disasters
I also have experienced the brake pedal going to the floor and not having any brakes when applied. The dealer replaced several parts to no avail. The first time it happened I was getting off the interstate highway and the brakes went all the way to the floor and I went straight through the stop sign at the end of the ramp. I believe the problem has been resolved but I am still very careful. I would love to find the exact problem.
Started vehicle placed in drive gave a little gas was unable to stop, I was standing on brake pedal but was not stopping until going through the corner post of my garage.
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.
