My vehicle was in motion every time the problem occurs. I lose all braking ability for approximately two to no more than five second periods. This has occurred on six total occasions on different days and months. I have replaced my vehicles master cylinder six months ago. I don't feel safe driving my own car. I have witnesses that can confirm this information. The problem has occurred on highways, public roads, also in private drives.

For the last few months I have had intermittent problems with my braking system. Many times, when I would apply the brakes as I was going over uneven surfaces or gravel, the abs system would engage and the brake pedal would lose pressure. During this time I would have to apply a much greater force to the pedal to get the car to stop. Almost every time this would happen, I would not stop where I was intending to, but would go by my intended target. Until today, this has not caused problems. However, today, I was traveling at a speed of approximately 25mph as I was going down a hill and approaching a turn. As I was applying the brakes the abs system engaged unexpectedly, the pedal lost all pressure and went straight to the floor, and the car was not slowing down at all. I lost control of the vehicle, went over a curb, hit an embankment and finally came to a stop. I had the vehicle looked at, immediately, by my local mechanic. He told me that the general braking system seemed to be in good working order (pads, rotors, calipers, hoses, pressure, master cylinder, etc. . . ) he mentioned that this model of vehicle had some problems with the abs systems and recommended that I take it to my local Ford dealer. I have an appointment with them this week. In the meantime, I researched the abs issue he mentioned and found the open investigation into exactly my problem. This is another complaint showing that this problem is very real and quite dangerous. Nhtsa action number: pe16017.

Driving in light snow approx. 20 mph, stopping at a stop sign pedal went to floor and remained soft, pumping pedal brought it up again slightly but stopping is very slow. After not moving it for a day, pedal came back up and seemed fine. Second time this has happened in 6 months. It is now in the repair shop as I feel it is unsafe to drive. Mechanics have said it is mechanical either master cylinder or abs valve but there is no test to determine what the problem is according to Ford mechanics. There are only 73000 miles on the car. Seems this happens when it is wet or snowing and it is random when it happens, however once the pedal goes to the floor it does not come back up to normal until after the car sits for a day. This is a very expensive repair and if it turns out to be the valve there is a 3 day wait to get the part, in the meantime I am forced to rent a car also. I have heard that Ford is well aware of this issue but is not addressing the situation or taking responsibility for poor design and engineering. In the meantime the consumer is forced to either pay for the repair or get rid of an unsafe car.

Issue happened 4 times in last year and a half. Slight skid twice on wet pavement, once on stone driveway, and once on wet metal sensor plate leading into toll booth. All 4 times were at low speed. Two times I was turning. Two times I was just slowing to a stop. Brake pedal went soft and braking distance increased. Soft pedal gradually improved over a period of weeks, but still felt softer than it should be and I questioned the reliability. The first time it happened, I took to a mechanic who couldn't find anything wrong. The last time I took to a Ford dealership, told them the symptoms, and asked them to check the hcu for the abs. They told me the master cylinder was shot and had to be replaced and they could only check the hcu afterwards, which turned out to be faulty. So they ended up replacing both the master cylinder and the hcu. The bill was $2000 but the brakes now feel like they are supposed to.

2009 Ford Fusion - brake system: I have been having trouble with my vehicle for over a year. When the anti-lock brake system (abs) engages while my car is in motion due to sudden stops, braking on wet surface, crossing uneven surface (railroad tracks) while braking, or maintaining speed while crossing a pothole my brakes become "spongy" immediately after. The brakes feel as if the brake pedal lost pressure requiring me to press my brake all the way to the floor. This has increased my stopping distance and has become a safety concern. These occurrences happened on a city street and/or highway and has happened going straight or turning. The speeds in which my abs has engaged occurred at or below the speed limit of the road I was on (I. E. 15 mph to 70 mph). At first, I would pump the brakes and my brakes would return to normal within an hour or so. It has gotten worse over the year or so and currently my brakes do not return to normal and are still in the "spongy" state. Last month I had my master cylinder replaced and I thought that had fixed the problem up until yesterday when my abs engaged again crossing train tracks while decelerating. My brakes are currently in the "spongy" state due to yesterdays event. I am uncertain to what the cause of the problem is but can speculate from online forums that it could be the hydraulic control unit. Please contact me if you need any additional information. I do not currently have my invoice from the master cylinder replacement with me but can obtain it if needed once I get home.

The car lost braking power. When the abs brakes engaged, I had to push the brake pedal all the way down to get them to engage. My mechanic replaced the master cylinder initially. This fixed the problem temporarily, but later, again when the abs engaged, the pedal got spongy and the pedal had to go all the way to the floor to brake. Then, my mechanic found that this was a known defect and replaced the abs control module, costing me > $1,000. The part cost $805. This problem should be recalled.

After the abs engaged on the car on some ice (going approximately 20mph) the brake pedal sank nearly to the floor. Now I have no abs and the pedal sinks to about 2 inches above the floor before braking starts. I have had the lines and master cylinder looked at and they were fine. The dealer believes it is the abs pump that has a stuck valve. Apparently this is not uncommon and needs to be a recall not just an expensive repair bill for something that could kill people.

My problem is exactly as described in the open investigation NHTSA action number pe16017 called "extended braking distance". After engaging the abs due to icy and snowy conditions, my brake pedal became very "soft" and almost goes to the floor. The typical braking characteristics are changed dramatically, much greater force and distance are required to stop the car. This is very repeatable. Pumpint the brakes did not immediately help, but eventually the pedal did come back to the normal position. During the summer of 2017 I must have had the same problem without realizing it, the shop replaced my master cylinder but as of yesterday it's obvious changing the master cylinder did not help. I see this as a major safety issue, I will not let my daughter drive this car again until this is fixed.

When driving brakes became very weak almost to the floor, we replaced the brakes with still no good pedal. Then we replaced the master cylinder, once it was replaced it would not bleed, and still no brakes. We called the Ford dealer and was advised the Fusions were difficult to bleed once master cylinders were replaced. We sent it out for diagnostics at the Ford dealer and were charged $98. 00. They called and said the system needed to be bleed before they could give us an exact answer of what was wrong and the would be an additional $100. They called a few days later and said it needed a master cylinder. We told them we just had replaced it. They said maybe it was a faulty part, so we picked up the car exchanged the part and still have the same issue. Called back to the Ford dealer and was told the only other thing it could be was the hcu and that was about $1600 to change. So 2 tow bills, and $200 later we still have no brakes. After extensive research we have seen this is a very common issue with the Ford Fusions and this is a very dangerous issue. Ford should issue a recall ! losing brakes while driving is dangerous ! I would like a Ford rep to contact me !.

Yesterday I was turning left from a 2 lane road onto the one lane street where I work and had to brake suddenly because a car was stopped at the entrance to the road. I believe this engaged my abs. Immediately after that, my brakes suddenly required me to push my brake pedal almost to the floor to engage it. I brought it to a mechanic this morning and they recommended I replace the master cylinder but that there is no test to know if that would even fix it. I googled this issue and come to find out it is a very common issue with a faulty hcu in all 2008 Ford Fusions. I do not understand why this known issue is not a formal recall as it is putting people's lives as risk including mine. Also, because it is not a formal recall, people are wasting hundreds of dollars on master cylinder replacement when that does not fix the issue at all. Please get this extremely dangerous issue addressed so everyone with a 2008 Ford Fusion gets the hcu replaced and can brake safely. Here are some links that describe this exact same issue on other Ford Fusions. Https://youtu. . Read more...

In November of 2017 my break pedal became unresponsive and would go all the way to the floor when�s pressed. It would break after I pumped my breaks but breaking was still compromised. I replaced my master cylinder and bled my breaks, checked for leaks to no avai. I took it to a mechanic and he�s could find nothing wrong but suspected the abs hydraulic control unit. This issue can only be handled by Ford dealerships. No harsh breaking occurred to cause the issue and I narrowly avoided an accident due to the failure (I had to swerve into the oncoming lane to avoid the accident). I feel this is a safety issue and should be recalled because I researched it and found numerous complaints that are similar to mine and I could�ve seriously injured myself or others due to the problem.

On October 20, 2017 my elderly mother had traveled about 150 miles out of town. When traveling a two lane road a funeral procession was coming the opposite direction. She had pull the car half way off the road with one side off the road and the other on the road. When everyone started to go again the car in front of her came to a sudden stop. When my mother tried to stop she had no brakes. She tried to leave the road to avoid hitting the car in front of her but she ended up hitting the right corner of the car. . Thankfully my brother-in-law was behind her. He drove the Ford Fusion 150 miles using the emergency brakes for stopping her car. It was mostly interstate miles to get her home. If the brakes had not failed until she was on the interstate this could have been a fatal incident. Her 2007 Ford Fusion has 85,000 miles. She loved the car because it handles and rides so well even though the dash is buckling and coming apart. Now she is afraid of it. Her mechanic replaced the master cylinder which did not correct the problem. The car was taken to another mechanic who replaced the abs hydraulic control unit which corrected the issue. This is a rare part to fail and it is a real issue.

Tucson, az. City driving; potholes and sand on roadways common. No evasive or avoidance skidding preceded poor brake performance. Brake pedal must be pushed nearly to the floor to get brake action, which is only partial brake effectiveness. Brake repair shop replaced master cylinder - no change in brake performance. Brake repair shop then replaced abs hydraulic control unit - brake performance returns to normal. Brake shop advised abs can activate with cause, then hcu valve sticks open, creating reported condition.

Takata recall. The brakes seem to not be fixable. I have replace brake pads, master cynlinder, flushed out break fluid, bled brake. Brake are still not working properly. If I hit a bump at a pretty good speed, the brakes get worse and then I have to push the pedal all the way to the floor and still doesn't really slow down. I have spent a lot of money on getting these brakes repaired and still not working properly. I hit on brakes to pull over and I hit a bump on the side of the road and brakes stopped working properly again. I don't know what else to do. I have had Ford dealership inspect brakes and they said I need to replace master cylinder. I replaced it and no change.

Soft and low brake pedal. So I have a2015 Ford Fusion se I recently changed my pads and rotor on. While on,the lift my battery died. After putting it back together ansld boosting my car I then had a soft brake and the pedal would not engage until extremely far down, I have shop has bled the system numerous times changed the master cylinder and still nothing. I was told it could,be a caliper doing,this and ialso,seen online it could be the abs mod. Everything I have read is leading to the abs module but nothing can be proved so I'm left to dump money in parts and hope it gets fixed. Fixing tgungs that are not broke is insane in my eyes. . . . . .

Have had 2 incidents of abs engagement followed by loss of brakes, where pedal went down to the floor. First time was in February of this year. Road conditions were slick and the car slid slightly. Abs was activated and then there was loss of brakes. Had the car towed to a local mechanic and the whole brake system was inspected. All that was found was some air in the lines and brake pressure came back. Rotors, pads, calipers, master cylinder were fine. Second incident happened August 5th while going on vacation. Was about an hour from home when I slowed down to go through a toll booth. Road was wet and I hit a slight bump going through the toll. After I got through the toll, brake pedal sunk to the floor! I then exited the turnpike and headed back home and drove it back an hour with no brake pressure. Fortunately it was early morning and traffic wasn't heavy. I got home, switched all of the luggage into my other car and I called a friend who works on cars and he said I could drop it off and he would look at it while we were on vacation. While he had it, the brake pressure came back. But again entire braking system was inspected and nothing wrong was found. There has to be a glitch in the abs. The first five years I had the car, nothing like this ever happened. Other on line postings I've read describe similar situations happening when the vehicle has 60,000 or more miles on it. My vehicle is at 60,000. Ford needs to look into this! does someone have to get seriously injured or killed before they take any action?.

I was driving down the highway at 70pmh, tried to slow entering a curve onto another highway, 271s to 71s, in ohio and had to hit my brakes hard because traffic jammed suddenly. I didn't have brakes at all, my abs never kicked in. I went off the side of the highway and even then couldn't stop with my foot all the way down. I nearly hit the person in front of me going about 50+. I took it directly to my mechanic who replaced my master cylinder again (2x in 5 months) and after he was done the pedal no longer brakes properly. When attempting to stop the pedal is nearly to the floor. It is akin to not having pedals at all. I have to stand on it to stop and even then its the panic feeling of being unable to stop. This is an issue that could kill and I've read many other stories of people with similar issues with braking. Ford said that happens sometimes when my mechanic called and gave no further reasoning to it. I don't feel safe driving a car I've had a year that's not even a decade old.

This past may 2017 I was in traffic and a car pulled out in front of me had to slam my brakes on and I barely got stopped ! scared me to death . . Brakes were extremely spongy by the time I made it home I didn't have any brakes at all !!! my husband replaced brake pads , calibers, master cylinder , and rotors ! well over $700 I paid out . Still have no brakes at all . This is a safety issue why is nothing being done ????? I'm the only income my family has and now I have a car almost paid for that just sits !!! it's yard art prett much . . . . I am spending a fortune to get to work and back and can't afford the $500 for theabs module / pump not to mention the cost to have it put on !!! this is horrible . . . I'm already die hard Ford girl but after his experience I will never buy another one . . . .

Brakes were operational w/ normal function/ response. I firmly pressed the pedal, to avoid a pothole, traveling over a railroad crossing. Immediately thereafter, the brakes became/remain 30% effective, w/ no loss of fluid. I've had my mechanic replace the abs module & master cylinder to no avail/ success. I'll now take to dealer for diagnostics, so I may unload/sell immediately thereafter repairs.

Brake pedal collapsing before brakes engage. Replaced vacuum booster and master cylinder in attempt to repair. Slightly improved but condition still exist, diminishing brake effectiveness. I relied on reputable shop for these repairs and spent $700 for only partial improvement. Google search indicates a failure in the abs valving. Unknown if abs works in this condition. Abs was severely engaged within weeks before failure. See the following from google "2008 Ford Fusion soft brake pedal. This video describes all circumstances perfectly, other than on this car, the brake pedal is constantly diminished at any speed whenever driven. . Read more...

While driving in my neighborhood I hit a rough spot in the road and my brake pedal went to the floor I could barely stop the car. I took the car to a local shop and they replaced the master cylinder and brake booster. Still no brakes, they replaced the abs module with a used unit a new one is 1300. 00 dollars and that fixed the problem 1168. 00 dollars later. I called Ford and if they could help me with the cost of this and they said it was not a recall. I will not be purchasing a Ford product in the future. The abs module in these cars are defective.
