Recently reported SERVICE BRAKES problems on 2011 Ford F-150

Started my vehicle and went to leave a gas station. stepped on brakes to stop for oncoming traffic and the pedal was hard as a rock and did not stop the vehicle. pressed super hard on the pedal and the vehicle stopped. it was fine after that until i got home, turned off the vehicle and left sit for an hour. started vehicle and the same issue happened again. did some research and found out about the brake vacuum pump issue. i called ford to see if my vehicle was on the extended warranty coverage (15n05), of course my vehicle was not covered. had my wife been driving this vehicle, i do not think she would have been able to press hard enough for it to stop.

Total loss of brakes, almost got into an accident. brake light warking suddenly came on, pulled over to check, empty brake fliud, fillled up the brake fluid, in 10 minutes all the brake fluid is gone. no signs of leak on the floor. towing it back to the hpuse

Brake vacuum pump failed which resulted in brake pedal being very stiff and brakes being very poor after a cold start.

Had ford customer satisfaction program 15n05 done on my truck january 2017 after vacuum pump noises in the front end. vehicle was at 90.5k miles then and is now at 120.5k miles. noticed a few weeks ago the vacuum pump was again making the same vibration noises at startup...probably even worse (noisier, several cycles of vibration instead of just one). since i was past their 1-year/12k mile warranty program on the unit, ford dealer and customer service have both declined to support another replacement in any way. was reading on f150 forums and other customers are experiencing the same faulty vacuum pumps after having the warranty work done. so, now i have a noisy vacuum pump and very slight pedal changes at first start-up that i must pay to fix. no incidents so far but now i'm on the hook for an additional repair after only 18months/30k miles with the ford recommend replacement pump. nothing on vehicles these days only has a 30k mile life. that's terrible. for safety's sake, i'm going to handle this replacement on my own and have no recourse at this moment for satisfaction besides to atleast ...

I own a 2011 ford f150 that was under a transmission recall that was very serious in nature: 16v248000 -ford motor company (ford) is recalling certain model year 2011-2012 ford f-150 trucks, 2012 ford expedition, lincoln navigator, and ford mustang vehicles. the affected vehicles are equipped with an automatic transmission that may unexpectedly downshift to first gear, regardless of vehicle speed. i had this recall performed and ever since, i've had transmission issues. the transmission does not respond as it should. the truck takes off very slowly as it accelerates (very dangerous in traffic). on top of that it has shifting problems. the dealership (eby ford in goshen, in) has been no help whatsoever. now, on top of not getting this taken care of, i now have another issue with the vehicle (that's also been an ongoing problem): 'field service action number: 15n05. my vehicle has 152,xxx miles on it and they're saying they can't cover this because it's over 150,000. i need help getting this vehicle in a a safe driving condition so that i someone doesn't end up seriously injured or dead. please help! these things ...

No or poor braking right after engine startup and traveling in reverse (vacuum assist). very poor braking at emergency or panic stop (as if the brake lines need bled). travel speed at about 45mph. only 27k miles on vehicle. similar to concerns that prompted the ford 19s07 warranty extension for the electric vacuum assist unit, but this vehicle is not covered by that. ford dealership wants over $100 to diagnose brake system. very scarry driving!

The brake vacuum pump is not working. i'm unable to get into my car, start it then drive off. it needs to warm up for about 5 minutes to fill the pump. based on research that i have done, there was a recall on this part 15n05. but my vehicle doesn't list it as a recall. can i get an explanation why my vehicle doesn't list the recall? thanks

Upon starting vehicle and beginning movement, the brakes do not work for a short time. engine light has came on. pressing on gas pedal movement is sluggish.

Power train coming on all time / brake problems/ light coming on all times

The brakes do not work in the morning when i start up my vehicle.

While driving down the highway the fault code for timing chain p0016 came on and engine seized in the middle of the highway. i lost all power steering and brake power which caused me to almost collide with other vehicles trying to get off the highway with no power. after finally getting truck on the off ramp it took all i had to get it to stop at the intersection putting my life and the driver of the suv at the intersection life in danger.

After sitting overnight, and turning on the truck the vacuum pump is extremely loud. if driving the truck immediately the brakes will not work unless pushed very hard. after about 3 minutes the sound diminishes and the brakes work adequately.

From a cold start, the service brakes did not work upon initial application. with extreme pedal pressure, truck eventually stopped rolling narrowly avoiding impact. incident occurred in our driveway.

Had complete brake failure. was able to get the truck stopped. saw it was 2 pints low on fluid. added fluid, drove towards my auto shop, had to stop to fill the brake fluid again (the light went on this time). did this a few times. just before i got to the stop, the truck blew out some smoke, chugged, and the motor seized up. towed the truck to the shop, they found out the master cylinder leaked and the vacuum lines sucked the brake fluid out of the master cylinder and dumped it into the cylinders in the motor and this blew my motor. i hear there is a recall for this on 2014 f-150s but not on the 2011. terrible design. a brake problem should not blow up my motor.

Vacuum pump and brake booster has failed on my f150. ford states that the vehicle is not covered under "15n05" extended coverage/recall. vehicle was manufactured at the effected plants during the time listed in the bulletin. ford is charging me over $1300 to fix my vehicle, despite this being a known safety problem.
