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 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.

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.

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!!!.

The first time this happened I was sliding into traffic due to icy conditions. After hitting the brakes hard and engaging the abs system the brakes became spongey and went to the floor. This happened again after having to hit the brakes hard again and this time we were on an interstate. My mechanic has replaced the master cylinder, brakes, and adjusted them. After this happening several times my mechanic researched it to find the the abs modules on this model are faulty. This has happened 4 times in the last year. This is a very dangerous and expensive defect on this automobile. After searching online I have read several complaints with this model and the same defect has been noted.

In November 2015 I took my 2008 Ford Fusion to a mechanic because the brake pedal went soft. As I recall, I hit a regular ole pot hole and the brakes were non-existent until I pushed the pedal all the way to the floor. When I took it to the mechanic, he said there was power steering in my master cylinder, and that I needed my master cylinder replaced. I allowed him to do so and the brakes were working properly again. In December of 2015 I was pulling into ted's hotdogs and the pedal went soft, again. I took it back to the same mechanic and he noticed the soft pedal. After bleeding out the brakes the brakes returned to working properly. He said he saw nothing wrong with it and called it, "weird. " when I picked it up everything was working fine. January 13th, 2016 I was returning home. There was snow on the ground and I was making a left turn onto my street. The brake pedal went soft again. This morning my mother took it to work and she was forced to run a red light at 5:30 am because she could not stop because the pedal was soft. Every time the pedal went soft, it was because I was making a turn. The speeds I was going at were 40mph, 35mph and 20mph. After further research, I have learned that it has nothing to do with the master cylinder, brakes, rotors nor calipers, but has to do with the abs and hcu.

After noticing braking issues I had a mechanic look at it to investigate what the issue maybe. I was told it was the master cylinder. This part was replaced and then after replacing noticed air going into the line. After noticing the sound of air there was air lines after the flush. It was determined a faulty abs sensor.

Have lost breaking when making turn and applying brakes on rough roads (in winter) the brake pedal went to the floor in order to stop and after quite some time the brakes would return to "normal" and then tis problem would reoccur, to date this has happened several times over a two and a half period, when taken into mechanic he could find no problem, he has suggested to replace the master cylinder, how ever I have never had a master cylinder fail and then fix itself and then fail over again and again, I believe it is the abs control valve and I feel that this is not a normal wear issue, and that Ford should do a total recall to repair this "safety" issue.

The brakes went all the way down to the floor, the Ford dealer said that there are 3 components in the system 1)master cylinder 2)hcu 3)power booster, he said that the master cylinder probably leaked into the hcu, which in turn messed up the power booster. The dealership also said that there have been numerous complaints from other 2008 Ford Fusion owners with the same thing. So our question is why doesn't Ford have a recall since they said there is a problem with the brake system on the 2008 Ford Fusion? now they want us to pay $2070 to have it fixed, we have a small grandchild that we transport to school daily, if something happens to the brake system, then what? we want Ford to have a recall on this before someone dies. How could all 3 components go bad at once????.

While driving on a gravel road at slow speed for about 3 miles I came to a stop sign/intersection. When I applied the brakes there was no resistance and the pedal went to the floor before it did brake and locked the wheels and slid to a stop. I drove another hundred feet and pulled off the road and it did the same thing; pedal to the floor. With motor idling I opened the hood and checked the brake fluid level which was full, closed the hood and checked the brakes and they were fine; a full pedal. I drove another 20 miles or so in stop and go traffic and the brakes were flawless, full working pedal, no problems at all. I then went to my local Ford dealership where I related the above to the service mgr. And was told there was no way to diagnose the problem since at that time everything was working fine. He advised me that it could be the booster or master cylinder losing vacuum , but there was no way to check it. I suggested trading the vehicle since it is dangerous to drive but that might get someone else killed. The service mgr. Said if/when it happens and does not change or correct itself, they could then fix it. When it happens again I fear it will result in an accident. What can I do? there are several forums, etc. That suggest I am not alone. I bought this car new and nothing has been done to it. I am so afraid it will happen again and cause an accident that I cannot keep it and I fear for anyone who purchases it. I need an answer.
