  • 57,390 miles


The contact owns a 2011 Ford F-150. The contact stated that the brakes failed to respond without warning. The contact turned off and restarted the vehicle. The brake pedal responded after the contact reset the computer, but the failure recurred. The vehicle was not included in NHTSA action number: PE15026 (service brakes, electrical system, service brakes, hydraulic). While traveling approximately 45 mph, the contact pumped the brakes and the brake pedal extended to the floorboard. The contact crashed into the preceding vehicle as well as the guardrail on the passenger side. The driver sustained minor abrasions that did not require medical attention. A police report was filed. The vehicle was towed to a collision center and the body damage was repaired. The vehicle was towed to an authorized dealer where it was diagnosed that the brake pump assembly vacuum needed to be replaced. The pump was locked up and blew out fuses, which indicated a malfunction or potential defect with the component. The vehicle was repaired by the dealer. The approximate failure mileage was 57,390.

After the truck had been parked for a week, I started the vehicle and proceeded to move it. There were no brakes for about 3-4 minutes. Every time the vehicle would be parked overnight, the brakes would be inadequate until they had been depressed several times. After that, they would be fine until it was parked for more than a few hours. On June 3, I took the truck to the dealer to have them looked at. At that time, I was informed that the brake booster had a leak, and they proceeded to replace the booster at my expense. They are now operating to my satisfaction.

At around 2 years / 40K miles the electric vacuum assist pump for the brakes began to make an abnormal sound and upon replacement was found to be excessively corroded, possibly due to salt spray.

The brakes on my 2011 Ford F150 failed due to a master cylinder failure. The engine then injested the brake fluid and blew the engine. Ford refused any repairs.

This F150 is a 3.5 ecoboost with electric brake assist vacuum booster. The vacuum booster started making a very loud noise when applying the brakes and it felt like the braking power was diminished. I took the truck to the dealer and they told me it was the vacuum electric assist pump that was bad. They did replace it and helped me with the price even though the truck was out of warranty by time. If this comes to be a recall, I would like Ford Motor Co. To reimburse me my out of pocket expense.

I own a 2011 Ford F-150 FX4 with the 3.5L ecoboost engine. Approximately 18 months (odometer 23,260) after I bought it I noticed that in the morning when I would start it and begin driving my brake pedal would be hard as a rock and would not work! I made an appt with my local Ford dealer and they confirmed that the vacuum pump assembly had no pressure at the brake booster and needed replace. Fortunately I was not in an accident. The vehicle was still under warranty and the repairs did not cost me anything. Fast forward another 18 months (odometer 44,693) to May 2015 and I was having the identical issue again. I took the truck to Ford and after testing they confirmed that I was having the same exact issue again and that the vacuum pump assembly for the brakes would need replaced yet again. Only this time I was out of warranty and it was going to cost me $900 to fix it. I reminded them that this is now the 3 vacuum pump assembly that needed replaced in a span of 3 years and that the design was obviously defective and shouldn't cost me anything. The dealership refused to offer any accommodations and told me to contact Ford Motor Company if I wasn't happy. I did that and after some haggling they offered to replace it and I would have to pay them $106, which I did. I have the Ford invoice's for both occurrences. I have zero confidence that the issue is resolved and that I will likely have to deal with this issue again in the near future. I am concerned for my safety and that of my family considering the brakes could fail at any time. I also believe this to be an exact match to current NHTSA investigation PE15026.

The vehicle was taken to the dealer to be diagnosed. The dealer was unable to duplicate the failure. The vehicle was not repaired. The manufacture was notified of the failure. The failure mileage was 44,000.

  • 26,093 miles
On several different occasions after starting my Ford F-150 ecoboost I experienced difficulty stopping the vehicle when approaching an intersection. My spouse complained that the vehicle "took off" after she put the truck in reverse in the driveway. I complained about this issue to the dealer on 3/16/15 saying that I was unable to stop at a stop sign. I told them it felt like I was being pushed into the intersection. My initial feeling was that the engine was overpowering the brakes. The turbo can be heard spinning up after a cold start. I am unsure if it is really brake or engine/transmission related....updated 09/15/15

No braking when just starting up. When you start the vehicle and shift into gear the brake pedal is very hard and it is very difficult to get stopped. I searched the internet for similar problems and found many instances of the same issue. Apparently the brake booster vacuum pump seizes so no power brake assist is available. After the engine runs for a short period the brakes will function normally. You will get no notice that this condition exists via a warning light or check engine light. This situation is very dangerous, a building, a tree, or a person could be behind you and you would not be able to stop. Ford must be aware of this problem because they re-designed the pump for the 2013 model year but have not recalled the 2011-2012 models to correct this problem. The parts are expensive ($700) and many on line posts say the parts are on back order at Ford. This is a serious safety concern and should be addressed expedited.

We purchased the vehicle in July 2014. We noticed after buying it that when starting the truck, the brakes are hard and no stopping ability. Once you pump it a couple of times and go to drive the brakes work normally. We talked to people in general and said some vehicles are prone to that issue when starting and that it's not a big deal. If you happen to be on a grade when this happens, you do drift until pressure is built up. I did some research online and found a video that explains the issue very well. It is a safety issue and a simple but costly fix. It has an electric brake pump instead of a mechanical one and seizes up when the vehicle is parked for prolonged amounts of time. We took the truck to Ford to have some work done when the mechanic brought up the brake pump and said the vehicle is unsafe to drive as is incase the pump would fully go out. It is over a $700 fix with labor and is something that was faulty in the engineering of the truck model and produces a safety risk for the driver and others in the surrounding area. youtu.be/sxo2qvwbdki I attached the link to the video explaining the pumps issue in regarding to the trucks size.

After the truck sets for 8-10 hours, when you start it up you will have a very hard brake pedal but no brakes. The vacuum pump that supplies vacuum to the power brake booster is sticking and failing to supply vacuum at start up. If I put the truck in neutral and press hard on the brake pedal for about 10-15 seconds the pedal will go down to the normal height ( the pump brakes loose and starts to supply vacuum) then the brakes will be fine until the trucks sets for an extended time. I removed the vacuum pump and found that the pump housing was busted. It looked like it had gotten moisture in it and had froze. In my search on line I found many people having problems with this pump.

At my house, the driveway is sloped. I had just parked the truck, turned the engine off, but left key in accessory position. My two daughters were in back seat (3 and 8 years old) watching a movie. I walked into my garage to drop off coffee, went back to the truck to retrieve pastries and then walked them into garage. I was out of the truck for 3-4 minutes. I went back to truck and took my three year old out of her car seat. She sits in rear seat, passenger side. I had her in my arms when I opened passenger side front door, reached across to remove keys. When I removed the keys from the ignition the truck began rolling down the driveway. My 8 year old was 1/2 out of the truck when it began to roll. I quickly put my 3 year old down and grabbed the 8 year old out of the truck. The truck was making a metal clicking sound the entire time it was rolling. Truck rolled down the driveway, across the street and into the neighbors yard. Their tree stopped the truck from rolling further into the yard and their house. The truck was still in park when I went inside to start it back up to move it back into the driveway. I drove it the Ford dealer about an hour later. Ford dealer and fomoco were involved for several months. Eventually a 'specialist' was flown in to look at truck. In the end, they claim there are no mechanical defaults and therefore, they are not responsible. They are unable to answer any questions as to how the truck did not move for the 3-4 minutes it was on the driveway when I was back and forth to the garage. They also have no explanation for how the truck rolled even though it was still in park when this happened. End results is Ford claims they never repaired or modified my truck. I have no way to prove they did or did not repair anything during the periods of time they had my truck in their possession.

Brakes fail when vehicle is first started and either backing up or pulling forward. Has happened more than 4-5 times since I bought the vehicle new in 2012. Since this problem is serious in nature, Ford should issue a recall before someone is seriously hurt or killed if not taken care of. It needs the attention of NHTSA now! Ford service did perform a technical service bulletin dealing with hard brake pedal during normal braking, but the diagnosis performed indicated an intermittent problem with the brake vacuum pump and the operation of the power assist brake. This part and repair in not covered now even tough it was indicated to Ford service department on a number of occasions. Ford has not admitted to a recall, but did redesigned the pump on 2014 models and later. Problem inherited to the F-150 eco-boost engine. Recall now!

Brake booster pump been replaced 3 times in a 2 year span. The last time within 3 months. Vacuum booster leaks when the vehicle is not running. When started and put into gear the brakes will not work until it the system can gain vacuum, approximately 10 to 30 seconds. If vehicle is put into gear you cannot stop it from moving. It nearly caused me to get into several accidents. The vacuum booster has been replaced 3 times with no success. This summer (2014) Ford had 1200 of the boosters on back order due to the number that were failing in the F150's. my vehicle could not be fixed for 6 weeks while the dealer waited for the part. If the issue is ignored the booster will have a catastrophic failure causing brake system to stop working and a potential for a accident.

F-150 4WD 6-cyl

  • 20,000 miles
Brakes were difficult to engage during emergency braking due to hard pedal. Braking seems more difficult than previous experience (like having no brake assist). After searching the internet for known problems, I verified a blown vacuum pump fuse. The dealer verified that the vacuum pump assembly was seized therefore blowing the fuse. I find it curious why a major brake component can fail while not setting a failure code or indicating a failure on the Ford display panel (check brake light, etc.). how can the vacuum assist for the brakes totally fail on a 2011 vehicle and not tell the driver there is a problem? why did the vacuum pump fail (internal pump bearings lacked lubricant and seized due to atmospheric moisture) with just over 20000 miles on the truck" why won't Ford fess up that they sold their customers a defective $750 pump" I guess Ford only knows!
