My breaks made a growling sound from the front left side behind the headlight. As time went on it got louder and the breaks were harder to apply in order to stop the vehicle. I took my truck to the local Ford dealer and they replaced the vacuum pump.they charged me $597.40 for this repair that I feel should have been covered by a Ford recall! the dealer told me that they had this same problem with numerous other trucks.I feel that this should have been a recall.

On morning start up in my driveway the brakes made a crunching sound w/ a stiff brake pedal and would still roll forward while brakes were applied and the engine in idle. The dealer replaced the brake vacuum pump and harness under extended warranty less $100 deductible. Brakes work ok now but concerned if will fail same later after warranty. The dealer was very professional and courteous. Problem mentioned in tsb 15-0105 as stated on my bill.

2011 F-150 ecoboost: My brakes have been failing on cold start-up for approximately 18 months. Braking is so hard in the morning, truck will not stop. I brought this to the attention of the benna Ford dealership in superior, wi on two occasions and they did nothing. I then did a little research on-line and determined hundreds of other 2011 F-150 ecoboost owners have complained of the same issue and it was determined that it was a flawed design of the vacuum pump. This is a very expensive part that is directly related to safety upon cold braking. Why has the NHTSA done nothing about this known problem for the past 2 years when this should have been a recall? I had to pay over $500 for a new vacuum pump that should never go bad

When first starting vehicle the brakes fail, they are hard to push and have to brake at all. Very dangerous after being parked on a hill, I rolled out into the cross road and luckily there was no traffic, found out online that is serious problem with year truck and model and should be recalled and fixed before a death occurs. It is the 2011 ecoboost 3,5.

When I first start my F150 2011 and move it the brake pedal is hard as a rock it will take at least a few minutes to get back to normal, but it happens all the time when first start up. I did some research and found that a vacuum pump that provides power braking gets corroded. In my opinion this part should be recall because is a safety issue you could loose braking, I checked on the part and it cost around $600. This issue should be looked into before someone gets hurt.

Vacuum assist pump went failed with no warning. Luckily it happened at a repair shop, but the fail was sudden and complete. If this had happened on the road either at low or high speed, it could easily resulted in loss of life. The fail was complete resulting in no way to stop the truck at all.

While backing out of my driveway one morning I was not able to brake because my brake pedal felt like it had seized and was stiff. I pushed extremely hard and it helped the vehicle slow down and there was a slight grinding sound. After the truck sat for a few minutes, the brakes began to work. This has happened to me on several different occasions now where when the truck has been idle not running for approximately 8 or more hours, the brakes seize and do not work for the first few minutes. I believe that this is caused by the electronic vacuum pump for the brakes malfunctioning. This is a serious safety concern because if the brakes should give out while I am on a main road and going full speed, lives could be in danger.

Brake pedal is really hard after start up, yet the brakes don't work. Brake assist vacuum pump whines few several seconds at start up. Truck rolled in the ditch at my house a couple times while I was backing out. Luckily, my ditch isn't very deep and no damage to my property or vehicle has occurred up to this point. This has happened to me several times, it is not an isolated incident. This is an expensive repair, and I really hope it doesn't cause me to collide with another vehicle or run over another person in a parking lot or somewhere similar before I can afford to perform the repair. According to my internet research, this is a fairly common problem with this model vehicle, and should really be recalled before someone is seriously hurt or even killed.

The contact owns a 2011 Ford F-150. While driving at approximately 20 mph, the steering wheel seized. In addition, the vehicle drifted slightly to the left and the brake pedal was hard when depressed. The vehicle continued to drift and crashed into the front of another vehicle. The contact stated that the "service advancetrac" warning message displayed. The air bags did not deploy. The vehicle was not diagnosed or repaired. A police report was filed and no injuries were reported. The approximate failure mileage was 75,000.

I have a 2011 Ford F-150 FX4 ecoboost with 44,100 miles. When the truck is first started after sitting for 4 hours plus, the braking system fails until the vehicle has been running for a couple of minutes at which point the braking system comes back. This happens every morning when backing down a flat driveway or backing out of my parking space at work (truck has been sitting for 8 hours). From what I am reading, this appears to be a common issue with 2011 Ford F-150 ecoboost trucks. I brought this issue up with my local Ford dealership and they said there was nothing they could do about it.

The contact owns a 2011 Ford F-150. While driving approximately 5 mph and depressed the brake pedal to stop at a stop sign, the anti lock brake warning indicator illuminated. The brake pedal was pumped and the vehicle slid into the intersection. The failure recurred on two other occasions. On the third occasion, while driving approximately 30 mph, the brake pedal failed to respond when depressed. The brake pedal was pumped as the contact slid into an intersection. The contact clipped the rear of a Jeep that was traveling approximately 60 mph, causing the Jeep to flip over twice before landing upright. The contact and the driver of the other vehicle sustained injuries that required medical attention and were transported by ambulance. A police report was filed. The vehicle was towed to a body shop, but the failure was unable to be determined. The damage to the vehicle was repaired. The contact also stated that when the windshield wipers were powered off, they would independently swipe across the windshield approximately every ten seconds. The contact stated that the fuse had to be removed so the windshield wipers would disengage. The manufacturer was not made aware of the failures. The approximate failure mileage was 59,000.

When starting the truck and backing out of my garage, I had no power assist brakes. I was able to press harder on the brakes, however I did come close to hitting my house and the ABS was activated. This is the second time this has happened with this vehicle. The first time was taken care of under warranty around 26000 miles. I was informed that since the vehicle is outside of bumper to bumper warranty coverage, and it has been over a year since I had this part replaced last, it would be around $600 for parts and labor out of pocket (for something that has failed twice in about 51000 miles).

No brakes when the vehicle first starts up. Start vehicle, shift into gear, pedal does not engage unless it is stomped on and even then its difficult to stop vehicle. I have taken this to dealership where purchased. First time dealer replaced front brake pads with a modified pad and recalibrated the ABS module. Second time they replaced brake vacuum pump and vacuum line. Third time dealer replaced vacuum line. All of these failed to solve problem, dealer contacted Ford tech line and Ford engineers told tthe dealer that it was a characteristic of the truck and could not be fixed we called Ford customer service and they opened a case. We recieved a callback from a Ford regional customer service manager and was told if this concerned us that we should just sell the vehicle and buy a new Ford since we have the Z plan. There are no warning lights that alert you to this happening! I can not longer even drive the truck I bought because I do not have the strength it takes to stomp the pedal down when this happens. Im so concerned that this truck could hurt someone. Im a 58 year old women and Ford does not even care to resolve this serious safety issue.

I was backing out of my driveway and felt the brake pedal get soft like I had no power booster. The truck was very difficult to stop. I had to pump the brake a few times before the pedal stiuffened up a bit. This has happened everyday since, but only in reverse and only if I go in reverse 1st. The pedal seems a little softer than normal going forward but not near as bad as in reverse. I replaced the front brakes on 7/25/2015 (rotors and pads- high end replacements) and that did not help the problem. I just replaced the rear brakes on 8/15/2015 (rotors and pads- again better than oem) and I can still tell there is something not right when I back up as a first action. The pedal still needs to be pumped a couple of times before it feels better.

As I start my 2011 Ford F150 3.5 ecoboost after it has sat for some time, such as overnight, I have no power brakes for 30 to 45 seconds, the pedal becomes stiff and the truck keeps moving even under heavy breaking. This is dangerous because I often park on an incline or on a steep grade. I have also lost my power brakes when I was pulling a trailer and had to take evasive maneuvers and use the transmission to slow me down until my brakes came back. At no time did I get a warning that my brakes were failing or any kind of code to check brakes I talked to the dealership and the said it was a common problem and that the brake vacuum pump had gone out. And they said for $600 they would replace the pump. I decided against it and he told me it would be fine to drive it like that. This seems so dangerous and Ford is unconcerned about possible brake failure and an accident. I don't let my wife drive it anymore because I'm not sure she would know what to do if it happens while she is driving.

The brakes on our truck have started to fail when the vehicle is first started. It used to be less frequent and only after sitting over night but has increased in occurrence and is now occurring each time you start the vehicle. If you put the truck in drive, there is a mushy brake pedal and the anti-lock brakes kick in. In reverse, the pedal is mushy and there are no brakes. Once the truck has been running for a few minutes and you have pumped the brake, the brakes seem to work okay. The dealership service department has replaced the vacuum booster but this did not fix the problem. Because the problem has gotten worse and more frequently, it is worries one that it may happen when driving. We trailer a lot and we live on a very steep graded road.
