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.

For around 8 months, often while braking my brake pedal will lose pressure and go almost to the floor. It doesn't lose all pressure but makes for a difficult stop. This has caused me several times to almost rear end other cars and not be able to slow down enough while taking corners. It happens in motion highway and city. More so on bumpy roads or harder braking. My mechanic, which is at a Ford dealer checks everything out for me every oil change. He states that there are no leaks and the master cylinder if functioning properly. I believe it was the hydraulic control unit that he suggested could be the issue. There are numerous complaints online about similar year cars having the same issue. I consider this a serious safety issue, I believe the reason I haven't had an accident is that I'm used to the issue now, but I believe it's a matter of time before an accident happens.

Once my antilock brakes kicked in this winter, my brake pedal never went back to normal. It is very mushy and sometimes when going slowly down a small incline (I. E. Exiting a parking lot), or over rough roads, it is hard to brake. In 2015 the exact same thing happened - my abs system kicked in once during winter and my brakes were mushy. Except that time, carx did a free brake examination, couldn't find the problem but when I got the car back. The brake pedal was firm again. This time, in 2017 I took to Ford dealership and so far, they have no idea what is wrong with it. Carx thinks I need a whole new hydraulic cylinder unit for abs and/or master cylinder.

Investigation opened 12/20/16 on 2009-2011 Fusions for soft brakes after abs deployment I suggest you add the 2008 year model as I have been experiencing the same problem. One month ago, the shop replaced the master cylinder to "fix" the problem, which worked until yesterday when the abs activated again.

Brakes went soft, replaced the master cylinder then I didn't have any brakes at all. Took it to my mechanic and he thinks the abs system is bad, I read a lot of comments on line to see that this is a common problem. I did stop on snow and the abs system work then after that the brakes went soft.

Brakes have become spongey and a lot of pressure is needed to engage the brakes. The master cylinder and the rotors and brake pads have been serviced and inspected. The Fusion has done this multiple times and now has stayed consistently spongey. All services have been done through the Ford dealership.

As stated in NHTSA action number: pe16017, my car is having the same issue of the brakes going to the floor and not being able to build brake pressure. I have fixed/replaced every brake component (calipers, brake booster, master cylinder) but have not replaced the abs control module. All research leads to this being the issue of the valves sticking open and causing not brake fluid pressure to build.

I was driving on a snow covered road and went to brake and the abs kicked in like it should, so everything was normal. Then afterwards the brake pedal felt soft and would just about go to the floor when it would be depressed. I did not lose my braking power all together but I would have to pump the brakes or begin to stop far in advance to be able to stop like normal. It was like that for about two weeks and then one day the brake pedal went back to normal, but this is the second time in two years that this has happened and it worries me that this will happen again. I have looked into the situation and from what I've read it seems that it's a problem with the abs control module and is pretty common. Most people and even dealerships diagnose this as a faulty master cylinder, worn rotors and a number of other things and they end up replacing what they thought was the issue only to have the same problem occur again! I have not replaced anything in relation to this problem due to the fact of my brakes going back to "normal" and the abs control module being so expensive to fix. So I am taking my chances that this will not happen again until there is a recall on this issue. I believe it is a safety concern because although I did not lose my brakes all-together, I did lose most of my braking power and it could happen again at a time where I need to stop quickly and don't have time to pump the brakes.

This is the second time we've had issues with the braking system on our 2009 Ford Fusion. The first occurrence was in August 2016, the second on November 30, 2016. This last time I took the vehicle to the local Ford dealer and had them do a thorough diagnostic check on the braking system. The dealership says there is nothing wrong with our brakes that they can document or replicate. However, the failure of the breaking system, temporarily, nearly caused an accident for my son this week. Back in August it was my wife that had the episode. In August she was driving on a wet blacktop four-lane divided highway and hit the breaks for a car slowing in front of her. Immediately she had almost no breaking function, with the pedal being extremely soft and going almost to the floor. This was not a case of pulsating abs action like normal. She was able to pump the brakes aggressively for a while and gradually get back enough breaking function to drive the car home. On inspection the brake reservoir was full. This week, the same thing happened on a perfectly dry concrete four-lane divided highway during a braking action when preparing to make a turn onto a side road. He nearly hit a brick sign at the college campus entrance. He pumped the brakes repeatedly and gradually had enough breaking function return that he could drive slowly to the parking lot. I took off work and drove down to meet him and tested the vehicle. The master cylinder was full to the normal level. There was no sign of leaking on any of the calipers or on the ground below. The brake pedal was still very soft but after pumping gradually returned to normal so that I could drive the vehicle home very slowly. We've now almost had two accidents when the brakes fail temporarily and without warning, then gradually return to normal operation. What is going on here? this is really scary and frustrating.

The brakes do not function properly. During any driving, the first third of typical brake pedal press is normal and the vehicle brakes normally. However the middle third does nothing additional to brake the vehicle and the last third brakes aggressively. I have recently replaced the brake pads, serviced the rotors, replaced the master cylinder, and bled the brake lines. None of these services have correct the issue. I have read many forums where other users were experiencing the same problem with the final solution being replacement of the abs control module; a very expensive part to replace.

I purchased this used car on sept. 28, 2016. Five weeks later, on Nov. 4, I was nearing a red light on a city street and began to brake. Unexpectedly, the abs engaged and I found myself without any braking power. I had to push the brake pedal to the floor until the car eventually stopped approximately 12-15 feet later. If another car or a person had been in front of me, I would have hit them. I immediately contacted the Ford dealership where I bought the car (autonation Ford of white beat lake, minnesota), told them what happened and then drove my car slowly to the dealership where they kept it for four days. They replaced the master cylinder and I was led to believe that that was the end of the problem. The dealership claimed that they didn't know what else might have caused such a braking problem. Five weeks later, on Dec. 10, 2016, the same thing happened on another city street as I approached a red light except this time the abs engaged because the road was semi-slippery after a snowfall and I had to brake a bit harder. Again, the brakes didn't work properly and I had to press them to the floor. My car ended up sliding through the intersection (against a red light) before coming to a stop. Luckily, there wasn't any other traffic or obstacles in the intersection or I would have hit them as well. I did some research on the internet and discovered that there have been numerous similar complaints with Ford Fusion abs systems, including a number of complaints made to NHTSA. (there's also a video about the problem at youtube. ) I discovered that the problem is often misdiagnosed and that the cause if a faulty/defective abs hydraulic control unit needing to be replaced in a significant number of Fusions built within the last several years. These Ford Fusions with faulty abs need to be recalled before there are injuries and fatalities, if there haven't been already.

When pressing brake pedal at any speed the pedal goes all the way to the floor. When I took to dealer for repair they told me that the problem was due to master cylinder. I paid over $800 for repair but the problem persists. Now dealer is telling me it could be the abs. They are asking for an additional $1000 to fix. Help me? I am continuing to drive the car.

Brakes go to the floor at different speeds greatly increasing stopping distance and poses significant safety concerns. Brake hcu (hydrolic control unit) /abs system malfunction poses issues with bumps in the road, and braking while turning even at slow speeds. Brakes return to normal after being pumped and no other malfunctions with brake system (brake booster/master cylinder/brake pads, calipers, brake fluid) operating normal after ase dealership master mechanics can be identified. Occurs in city streets, driveway, parking lots.

Brake pedal goes to the floor before brakes start to engage. Local shop isolated any issues with the wheel brake assemblies and stated that is was either the master cylinder or the abs module. Brakes will engage sooner in the pedal travel if they are pumped once. Based on research it appears that it is most likely a stuck valve in the abs hydraulic unit.

I own a 2009 Ford Fusion sel with the 3. 0 engine. I have a problem with the brakes. The brake pedal is very sponge, I have replaced pads, calipers, and the master cylinder. This has not taken care of the problem, I have reviewed other information and it seems this is a very common problem. Ford has not done anything about it. I have researched more of this problem and the only thing left is the abs pump and motor. My research shows this has taken care of the problem, the cost to do this is approximately $1500. Plus labor cost. I have not had any close call accidents as some of the other complaints. This is and could be a accident waiting to happen. This problem occurs all the time while driving.

On cold starts this summer I back out of my driveway and press the brakes to stop and the brake pedal is rock hard and I can't stop. This is going to be my third time for this problem. The dealership has replaced the brake booster, master cylinder, brake fluid reservoir and brake booster check valve and vacuum hose.

Several near miss accidents occurred with my 2008 Ford Fusion, after my brake pedal went "soft", the car took longer to stop in most driving conditions, particularly slippery, snowy, roads. The brake would require to be pushed nearly all the way to the floor to successfully stop. The brakes would require this no matter what speed I was traveling it, particularly very dangerous on highways. The brakes being in this condition led me to not use the car on highways or in slick conditions. As a result of these brakes, I had to have my car serviced and have the abs pump & master cylinder replaced, leading to $1,700 repair. My local mechanic mentioned that Ford has seen this occur on numerous occasions in Fusions, yet has not put a recall out. As a driver with two small children, I was unable to use my Fusion for 3-6 months during any slick road conditions due to the bad brakes. I had numerous near miss accidents occur. I would like for Ford to be investigated on this part and be refunded for my cost of repair if it is recalled.

Took car in several times because brake pedal went all the way to the floor for it to stop. Dealership stated it was the rear brakes, replaced them. Problem still exist. Took back a couple mos later, dealership stated front brakes & rotors, fixed. Problem still exist. Took car back again, dealership stated master cylinder needs to be replaced. Replaced it. Took back again, now they state it's the hydraulic control unit in the abs system. Need to press brake pedal to the floor to stop.

I was driving at 40 mph on the highway in rain, abs kicked in because the car started sliding, brake pedal vibrated and after it stopped the brake pedal feels loose. I have to push the pedal almost all the way to the floor for brakes to engage. I've tried pumping my brakes but it's been a week since it occurred and I've experienced no change. I took it to a Ford dealership and was told the master cylinder needs to be replaced but they seemed so clueless I feel like it was just their best guess. I've researched the problem and I've found out that hundreds of people are wasting money on their cars trying to fix the same issue I'm having. I've recently received the airbag recall notification on my car and now a problem with my brakes has occurred. I don't feel safe in my car anymore and I hope Ford will take notice to the hundreds of complaints about the brake system.

During summer 2016, slammed on brakes and swerved left thus activating the abs at highway speeds to avoid an accident with another vehicle that was changing lanes without looking, at which time, my brake pedal went to the floor and brakes lost stopping power. Car continued to have diminished braking with pedal traveling to floor and taking a lot of extra distance to stop. The next day it appeared to somewhat correct itself but pedal still had extended travel and spongy pedal. Took to mechanic who could not diagnose but thought it might be the abs or master cylinder. Continued to drive with spongy pedal. Four months later, abs activated after sliding on icy road, pedal again went to floor with little stopping power. The car would not stop within normal distance even on clear surface. Carefully drove it home and scheduled dealer appointment. Took car to two different Ford dealers because first estimate was so expensive, but both diagnosed problem as abs hydraulic control unit. Replaced hcu and brakes are back to normal feel. Repair paperwork available upon request.

As I came to an intersection, I was depressing the brake and the pedal went all the way down. Ever since then, I have to press the brake pedal all the way to the floor of the car in order to come to a complete stop. Every time the brake pedal is unpressed their is an "air" noise coming from the hood of the car. I have changed the brake fluid cap, bled the brake lines, changed the calipers, and even replaced the master cylinder and the problem is still the same: brake pedal has to be depressed all the way to come to a complete stop and every time the brake is unpressed it makes an "air' noise. My dashboard never lit up with a warning before this happened.

In winter 2014/2015, cars brakes quit working while driving in snow. I took the car to a mechanic who could not replicate the problem. Drove car for about a year to this past winter 2015/2016, when driving on snow attempted to slow down at traffic light for a left-hand turn doing 45 mph when breaks quit working again. I could not stop and cars slid through intersection. Finally coasted to a stop on side of road. Took her back to mechanic who replace the master cylinder. On April 20, 2016, I pulled into a convenience store and hit a bump in the parking lot breaks quit working and I almost ran into the building of the store. After sitting in park and pushing the break as I had done previously, they worked fine and I was able to drive home. I may 3,2016, I pulled into that same convenient store with the same bump and lost my brakes again. This time bumping the curb before I stopped. I called Ford I may for 2016 after doing some research online and finding that this is a common problem with the 2008 Ford Fusion yet there is no recall. Ford said unfortunately there is no recall but I could take my car to a Ford service center for repair. I feel this is a serious safety problem and I could die or end up killing someone else because I can't stop.

On three occasions, upon suddenly braking, brake pedal failed. Took it to Ford once and they couldnt tell me what was wrong. Ford dealer said, "must've been a freak accident. " I ignored the second time brake pedal went to the floor as pressure built up soon after, but the third time, took it back to Ford dealer. They quickly said it was the master cylinder. I didn't accept the diagnoses. Did some research and found online that there are so many other 2008 Fusion brakes issues like mine! and no recall!?! research points towards the hydrualic control unit, the mechanical part of the abs module is bad. And it's a common issue! people can die over this! I have no abs indication showing on my instrument panel. . . On all three occasions I was driving on level roads or highways. How can Ford not fix this? is it not common enough just yet!?! maybe let a few die and have the media have a field day with the deaths before Ford responds??? Ford has a responsibility to its vehicles! where's the pride and good will from Ford? god forbid Ford take responsibility and make a recall and prevent them from taking away from there profits!!!.
