F-150 4WD 6-cyl

  • 69,650 miles


During first startup of the day, the electric vacuum pump makes a terrible noise for approx. 10 seconds as it builds up assist vacuum pressure. The brake pedal becomes hard as a stone with no vacuum assist. This is due to a faulty design with the pump assy. It becomes corroded internally and externally, and the piston inside the cheap housing becomes corroded and the pump will eventually seize. This is definitely a dangerous issue. If the pump seizes, there is not enough vacuum assist coming from the engine to provide enough vacuum pressure to the brake boost system and the pedal becomes hard as a rock to press. This happens every day during first startup in the morning, and start up in the afternoon when the vehicle sits for a long period of time and vacuum pressure depletes.

Started truck and pulled away, pressed the brake pedal to stop and no brakes. As truck runs a few minutes the brakes start working. Failed 2 days now. Ford wants about $600 for replacement of vacuum pump. Should be recalled for safety.

F-150 4WD 6-cyl

  • 32,000 miles
On 27 December 2013, I returned home from work sometime between 5-6pm. I parked the vehicle in the driveway just as I had every day since I have owned the vehicle. I put the vehicle in park, and exited the vehicle and walked to the passenger side to retrieve bags that I had to take into the house. I opened the passenger side door, took out the bags, closed the door, and pressed the lock button on the key fob as I walked into my house. I remember it was a windy day and as I recently researched, gusts were up to 27 miles per hour during the time in question. Approximately 45 minutes after I went into the house, the neighbor was at the door and told me that my truck had rolled down the hill. In panic and disbelief I ran outside to see that my truck had rolled down my driveway, but since the wheels were slightly turned, it stopped in my yard after running into the mailbox. I quickly ran down to the vehicle and tried to open the door but it was locked. I put in the code and unlocked the truck. I then ran into the house to get the keys. I had not brought them out the first time I ran out. When I got back in the car, I noticed that the gear selector in the dashboard did not have the orange line it usually does when in park. It looked like a smaller line, almost as if it was somehow between park and reverse. When I assessed the damages the truck ran into the mailbox and busted the driver's side tail light. T the next day, I took the truck to the dealership. They said they could not find anything wrong with the vehicle, and stated that they would not pay for the vehicle damage even though it was still under factory warranty. They suggested a file a claim with my insurance. I filed a claim with Ford, but they stated that my information did not substantiate my claim of a manufacturing or design defect.

"check brake system" warning appeared on dash display. No problem found with brakes. Turning off the ignition for a time seems to return things to normal until the next episode which has happened many times. Two dealerships have not found the problem. Outside ambient temperature seems to play a part since no problem in winter. This is not an isolated issue since a search of the internet confirms other owners have the problem. I have become inclined to ignore the warning but worry that there may be one time when there is a true problem that if ignored may jeopardize the safety of my vehicle and passengers.

Below is the email I sent to Ford, please help me. I have just bought a 2012 F150 ecoboost and have had a issue with the breaks when in reverse, I almost crashed with my 3 year old son in the car the first time this happened, a quick google search showed that this is a common issue, a issue I am sure you have heard of, I am an iraq war vet who could have been killed along with my 3 year old son because of this defect, I demand answers this is a serious safety defect and I am putting you on notice no denying you knew about this when someone is killed. Here is a link documenting this issue www.F150online.com/forums/2009-2014-F-150/500762-ecoboost-no-brakes-first-thing-morning-here-S- I have taken it to the shop repair bill of $890 this is why Ford is not recalling it, although they changed the part in model year 2014.

The vacuum pump on my ecoboost truck needs to be replaced. When I start my car every once and while the brakes are super stiff and it has trouble stopping the car for a few seconds. After driving for a bit the brakes are fine. This seems to be a common issue with the 2011/2012 ecoboosts.

The contact owns a 2012 Ford F-150. While driving 5 mph, the eco boost braking system failed. The contact was able to engage the eco braking system once the vehicle was driven for awhile. The failure occurred multiple times. The vehicle was taken to the dealer, but was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 5,874.

F-150 6-cyl

  • 33,000 miles
I am writing to complain about the failure of the vacuum pump on our 2012 Ford F150 with ecoboost. Once the vehicle had been driven around 33,000 miles, we began to notice some issues with the brakes immediately following startup: The brake pedal was difficult to press and unless pumped several times before moving, the brakes would not fully engage. This in other words, the vehicle could not be brought to a complete stop in a normal or safe amount of distance. We informed the technicians at our local Ford dealer of this issue while having the annual inspection completed. Ultimately, they found the vacuum pump to be completely inoperable and it had to be replaced. Fortunately, no accident occurred before we had this part replaced, but the potential was significant. Ford should take some action to prevent any possible crashes that may happen as a result of the early malfunction of this component.

After the vehicle is started and placed in gear, there are times when no power brakes are available and the vehicle is difficult to stop when it is only rolling at a few miles per hour (less than 5mph). You have to stand on the brakes to stop the vehicle, and if I'm towing a load when this happens it's a very scary event because the vehicle doesn't stop when you need it to stop. When pulling out of a parking position in a parking lot, I've come close to hitting a parked vehicle when my vehicle wouldn't stop as you would expect it to. I had my vehicle into the Ford dealership today to have this vacuum brake pump replaced to correct this problem, a problem that they know that exists and that is a safety issue, and I was told that the part will not be available until halloween timeframe.... a 3.5 month back order. This is the most popular selling vehicle in North America, and if this is happening to only a small percentage of Ford F150 ecoboost's, it's only a matter of time before an individual is seriously injured or killed from this vacuum brake pump failure on this vehicle equipped with the ecoboost engine.

Brakes engaged partly when I was going down the road without stepping on the brake. This has happened several times. Dealer turned rotaries but did not solve problem. This truck had less than 10,000 miles when this problem was occurring. I have taken the truck to two different dealerships, but Ford has not corrected the problem yet. The reason I bought the Ford was to respect the workers who did not take the government bailout and to get better gas mileage. I feel this is a safety issue.
