Electric vacuum assist pump failures that resulting in the loss of brake power assist'making it far more difficult to get the vehicle to stop. This vehicle has 39,000 miles on it and it gives no warning. I am concerned with injury or a crash. The dealer states this is not a current recall. I have noticed there a several complaints and some crashes have occurred because of this issue.

I have a 2012 F-150 with the 3.5L ecoboost engine, 100,000 miles. I have been having problems with no power brakes when truck is initially started and the dealer diagnosed this as a failed vacuum pump this typically happens at slow speeds the first several times you stop. A recall was forced in Canada and a customer satisfaction warranty extension is in place in the usa (15N05). Both cover the 2011 to 2012 F-150 with ecoboost engine. For some reason my VIN is not included in the recall & customer satisfaction policy. Brakes intermittently have no power assist and its very difficult to stop truck, especially when you arent expecting the brakes to fail like that. This is a common problem and I have contacted Ford customer service - but all they will tell me is my VIN isnt covered. They need to expand this to cover more vehicles - its a huge safety related issue. I cant believe no recall has been issued.

In February 2017 while backing out of a parking space on a down hill slop I was unable to stop the vehicle and into grass area almost hitting a tree in reverse. The power brakes were so hard I could not move the brake pedal. Once it came to rest I put the vehicle in drive and let off the brake pedal then reapplied the brake and they worked. I then took the vehicle to the dealer and they performed a recall fsa 15N05 on 2/27/2017 with 35,514 miles on the vehicle. Then on 2/16/2019 I was backing out of my garage and again could not stop the vehicle and went into grass hill of my yard.again my brake pedal was hard and no power brakes. When the vehicle came to a stop I let off the brake and reapplied and they started to work again. I took vehicle to the dealer that day for them to check it out. They notified me it again was the brake vacuum pump has has failed again and Ford will not fix it since it was fixed once before under this recall. The dealer also told me they cannot fix it due to the pumps being back ordered for at least 30 days. So the first recall repair only lasted 19,108 miles and less than 2 years. Luckily no one was behind me behind me to get run over and no damage occurred. My feeling that this is clearly a safety issue and parts should last longer. It appears to be a problem since the part is now on back order and looks to be a poor design.

The vehicle was in motion and as I was driving in a parking lot I went to apply the brakes but the pedal went to the floor and the low fluid indicator came on. I was able to use the parking brake to get the vehicle to stop. I opened the hood and found my reservoir was nearly empty but there were no signs of leakage around the reservoir. I got under the vehicle and could night see signs of leakage on brake line or any of the calipers.

Theory - vehicle manufacturers can simulate or induce failure of various parts/systems through the computer programming systems that run vehicles causing vehicle owners to make unneeded repairs which creates demand for parts and labor throughout the dealership network. My vehicle has had the following issues arise after the warranty expired. 1) dashboard display of gear vehicle is operating in stopped illuminating 2) windshield wiper stays on lowest intermittent setting after wiper is turned off 3) vehicle makes noise for 5-10 seconds following ignition during which brake pedal is soft. 4) sound of grinding/scraping from the front end 5) power steering is stiff during low speed turns my response to these situations were/are as follows: 1) checked the fuses - everything was good there. Several months later the display illuminated and has stayed illuminated ever since. 2) the local dealership recommended replacing a $100 part - I continued to switch the wipers on and off until wipers stayed off. Situation still requires on/off switching sometimes but has improved over time 3) the local dealership recommended replacement of a $400 brake vacuum pump. I continued to wait for brake pedal to firm before operating the vehicle and the situation resolved to normal presently. That is to say there is no problem with the brakes. 4) took the vehicle in for service and incurred a $700+ charge for iwes system. Dealership said the check valves had stuck open and dirt and dust had entered the system requiring replacement of parts 5) this is the latest issue with the vehicle. It only happens when turning after a stop and doesn't happen every day. I suspect it will resolve itself overtime if my theory as stated at the top is correct.

The contact owns a 2012 F-150. While driving in reverse, the brake pedal was applied, but failed to respond and traveled to the floorboard. The vehicle was taken to bill brown Ford (32222 Plymouth rd, livonia, mi 48150, (734) 399-4244) where it was diagnosed that the front brakes needed to be repaired. The brakes were replaced, but the failure recurred. The manufacturer was not contacted. The failure mileage was 70,000.

Bought 2012 F150 w/ ecoboost new. At 91K miles, experienced loss of power when accelerating while merging into heavy traffic flow. As a result of no power, we were almost T-boned into the passenger side which would have severly injured or killed my wife. Come to discover there is a chronic timing chain design defect and caused catastrophic engine failure at 91K miles. The engine was maintained religeously and oil changes were with nothing but high quality amsoil. Ford knows about the timing chain problem with the 2012 3.5 ecoboost motor. Ford mechanic stated the failure was most likely delayed due to using amsoil, the failures typically occur earlier than 91K miles. Ford will not do anything about it. Ford dealer is putting a new Ford motor in it entirely at my expense. Also the vehicle had a recall for a brake problem involving the electronic brake vacuum system. Ford completed the recall but must have replaced the faulty parts with the same new faulty parts because it is happening again. Ford again will not stand behind their product and fix or cover the costs of the design defect problem. Ford even addresses this problem with their customer satisfaction program 15N05. Niether the Ford dealer completing the repairs or the Ford dealer where I purchased the truck new are able to do anything about the problems because Ford Motor Company will not allow them. Ford is at fault and both are safety issues that they refuse to fix. These defects are unsafe and unacceptable. So much for Ford customer satisfaction. I will never buy another Ford product again!

2012 F150: Replaced the vacuum pump in Oct 2016 based on recall and issues with pressing the brake down when starting up. Same issue started again in June 2018. Brought it back to liccardi Ford and they state the issue is "brake booster vacuum pump sensor and pump relay". they charge me $140 for diagnosis and when I pick up the truck for a second opinion, the "check brake system" warning light is on. I did not have this issue when I dropped it off.

Loss of braking while backing up just after cold start, due to vacuum pump failure on 3.5L ecoboost, reference Ford customer satisfaction program 15N05 & NHTSA investigation - even after having repair done previously by Ford under the program / extended warranty - vacuum pump failed again less than 2 years after first vacuum pump replacement causing the braking issues

While attempting to start the truck I place my foot on the brake it is hard as a rock, will not move down or allow to use, put vehicle in gear no brakes almost drove through garage door this occurs every time I use the vehicle the cause is brake assist vacuum pump which should cause a recall, as somebody who uses this truck or one like it with the same problem could run over somebody no photos available as the part is hidden behind the left front headlight

When I start the truck I have to let it idle and warm up for about five minutes. If I do not let the truck warm-up and I put it in gear the brake pedal is very firm and the truck will not stop. The brake pedal pulses like the ABS system is kicking on but the truck will not stop. Recently, the truck will not stop if cruise control is turned on. If cruise control is on and I push the brake pedal the brake pedal is very firm and cruise control will not turn off and the truck will not slow down. I have to manually turn off cruise control from the steering wheel and then the brakes will work again. I was driving down interstate 44 in Oklahoma when I tried to hit the brakes and the truck did not stop. Before I left on the road trip I let the truck warm-up so that the brakes would work when I first left the driveway.

Our 2012 raptor that we have had since new, with 63K miles, was driving fine when the brake fluid light and emergency brake lights came on and lost all power braking. We were able to get the truck to the dealer without an accident and it was diagnosed with a failed master cylinder which bled into the brake booster. We can update with work receipts when we receive the truck back next week.

I purchased the vehicle as certified used in 2014 with 32,000 miles. Since ownership, we have taken the vehicle to 4 different dealerships around the St. Louis area with complaints of excessive brake noise on start up. All dealerships have mentioned that it's normal and vehicles will make some noise after sitting. This issue can happen if vehicle is driven, parked and then moved within a 15-20 minute period. The noise was to the point of being obnoxious, at approximately 65,000 miles I replaced the brakes on both axles. The problem still continues to happen and has gotten even worse. Appears that there is already a service bulletin and Ford extended warranty regarding this issue, but multiple dealers have made it appear that there wasn't an issue.

I filed a complaint # 11078458 about the brake vacuam booster pump, that has already been replaced once and neglected the fact that I was involved in a low speed accident on 1/17/18, and did not connect them until reading on line. I found out about the problem 3/10/18 the accident was at an intersection, trying to accelerate into traffic from stop when car in front dead stopped at green light. Speed at time of impact 4 mph?

I had NY truck in for service, was told there was a recall on vacuam oump and it was replaced. I did not initiate that repair. Less than 75000 miles. Now truck in for service again and I am told the pump needs to be replaced again, again not initiated by me, but now not covered. Still less than 100,000 miles. Pedal has no assist at startup. Hard to stop after startup

Ford issued recall 15N05 for the electric vacuum pump. This was to be a onetime fix which I had repaired when it failed. The new electric vacuum pump failed again 20,000 miles and 13 months later with the same issue. Ford will not repair. The parts are obviuosly faulty as my dealer told me several F150 trucks they repaired unter this recall are breaking again.

The brakes give out periodically I was almost involved in a collision due to it I took it to asheville nc Ford and they replaced a part but it is still doing it I now live in elko nv I checked for a recall and it says my trucks VIN showed no recall but it's doing the same thing as the trucks on recall. As I'd start in the morning and apply the brakes they'd be stiff and not work I'd try pumping them and they'd growel and barely work then after a short time they'd be find they gave out once while I was driving almost causing a wreck that's when I took it to asheville Ford nc and thought it was fixed but it's still doing it and you never know when it's going to happen not a real warm feeling
