While traveling the vehicle unexpectedly puts itself into park. The vehicle then locks up the breaks and skids across the road. After skidding the vehicle's throttle does not work and the vehicle is inoperable. This has happened for approximately two (2) years. It has happened while driving at high speed (70 mph) on a limited access highway facility. It has occurred at stop lights. In one instance while at a stop light the vehicle ceased to operate and was struck by another vehicle. Last week was notified by the vehicle manufacturer that they were conducting a recall for the exact reason that has caused me problems for the past two years. The malfunction has caused mechanical damages to the vehicle's suspension, steering, tires, and acceleration. The vehicle vibrates uncontrollably at any speed over 35 mph. There are also rattling inside and outside of the vehicle.

I have a 2011 Ford F150 ecoboost. I received a extended warranty for issues occurring with the electric vacuum pump. I have diagnosed an issue with the brakes after starting the truck up. I started the truck up put it in reverse backed down the driveway and lost all ability to brake and stop the truck. If there was a vehicle or individual behind me there could have been an accident where injury or death could have occurred due to the inability to stop the truck with the brake pedal. I brought the truck to the dealership with the issue and they ignored the electric vacuum pump stating that it was the master piston and it would cost 700 dollars to fix. After doing research I believe I was lied too after others have reenacted the same situation that has occurred to me. If the braking issue occurs more than once I will escalate this issue to higher authority individuals at Ford. This issue must be fixed before injury, death or litigation occurs.

The brake vaccum pump makes noise on start up. This is the second one since I have had it. Theremember is also a loss of brake pressure. When tapping the brakes in reverse the pump will always make like a build up noise. Also extreme brake dust is visible on rims. I have brakes and roars just under the best you can get.

The truck brakes did not work once the vehicle was started. The engine was at fast idle, placed in drive and the brakes would not function. This lurched the truck forward while extreme pressure was applied to stop it. Dangerous in a parking setting where a pedestrian is walking in front or behind the truck. It jumps forwards or back, depending if drive or reverse is selected. As time went by the brakes became weaker when applying at stops. As I reflect back in the past when pulling a trailer it hit the backend of another vehicle in an emergency stopping situation on the interstate. The truck would park well in the garage, but when pulling out you have to be aware of it lurching into the house or another vehicle. Took the truck to Ford dealer which diagnosed it as a brake vacuum pump failure. The eco boost engine is turbo charged which robs the vacuum system of needed vacuum. To supplement the need for vacuum this vacuum pump was engineered into the system to provide additional vacuum. If it failures the brakes fail also. The 2014 models have been reengineered to a mechanical pump eleminating the electrical pump. The Ford service man said that there have been a range of numerous brake failures due to this pump configuration. The Ford garage charged $832.57 to get us back on the road and for us to have a safe trip.

No brake boost upon starting, when you start the motor when cold there is no brake vacuum boost for about 15 to 20 seconds.. the "brake assist pump" behind the left headlamp corrodes and locks up and untill the motor gets enough vacuum there is very little braking ability. Ford gave me a new pump but I had to [xxx], I know you are looking into this, just wanted to let you know. This could very easily be a very dangerous situation. There should be a recall. Please don't wait until a child gets crushed under a pick-up to act. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I was pulling into a drive and my brake pedal went all the way to the floor. Luckily there was not a car in front of me, however it took much longer to stop the truck. My mechanic said it was the brake master cylinder...at 50K miles, Ford should cover this.

No brakes when first started up. I had to throw it in park to keep from running over hill. After searching on line I find that this is a common problem with ecoboost trucks. Ford should recall these and put the updated part on.

- Point Pleasant, WV, USA

Bad vacuum pump causing the pressure in the brakes not to function properly. When you press on the brakes its really hard to stop in motion.

- Burlington, NC, USA

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.
