Failure Date: 11/18/2016

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.

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.

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.

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.

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.

I have a pending case with Ford . The number is cas-7605243-r8k8v5. Brake problem is intermittent. On several occasions the brakes have gone spongy and require a lot of pressure to stop the vehicle. The brake pedal has to be pressed all the way to the floor and even then the car "slips" several feet before it stops. On two separate occasions I've almost hit a pedestrian who has stepped out into the street at a cross walk. I've taken the car to a dealership and they have replaced the master cylinder and booster. Second time was told the brakes were "normal" even though the service manager was able to replicate the issue. Ford fixed this issue for hybrids and I've asked multiple time for them to look into this for the conventional Fusions. . Read more...

Brakes failed, went all the way to the floor. Had to put the car into first gear, pull over to the emergency lane, and pump madly to get brakes to finally stop the car. This is the third time it happened, and by far the worst incident. Had to pay Ford dealer $1688. 00 for new master cylinder and new hcu. Went online to see if there was a recall. So far, none. But scores of other complaints on several web sites describe the same situation, same cost to repair.

I took my car into the dealer to have my brakes checked. I was told I needed new brakes and rotors, after replacing brakes and rear rotors drove the car out , less than a quarter of a mile on the way home brake paddle went down to the floor. Return to the dealer was suggested I need a master cylinder , the master cylinder was replaced was told that was not the problem. No one knew exactly what it was for two days, I was called and inform it was abs valve module. Ford dealer had to order valve module one week later still waiting. Don't understand why there is no recall. (many complaints).

While driving the vehicle and needing to come to a stop the brake pedal is soft and goes striaght to the floor. We have had the brakes checked and all the fluid and those are fine. I have been told that it could be the master cylinder but probably the hydraulic cylinder unit. The dash by the passanger air bag is lifting from the dashboard. I have seen many of the same exact post for both issues. A recall needs to be made on these parts before someone seriously gets hurt. This is unexceptable that Ford is not taking car of these issues. There is obviously a serious problem with as many people that are reporting the same exact issues that my car is experiencing. Take this serious please, submit through recalls so people don't have to die or get seriously hurt in an accident to get your attention.

2009 Ford Fusion sel v6 I am having issues with the abs system. The brakes are soft and really only activate when pushed almost to the floor. The issue started at about 75000 miles. I have replaced the brakes, bleed and replaced brake fluid, no leaks, checked calipers and master cylinder. The problem is the abs hydraulic control system. When replacement of the fluid and brakes the problem resolved until I made a sharp turn to the right and had wheel slip. Abs activated and from that point on it lost most braking ability. After much research I have found this is a common problem among many small Ford manufactured vehicles. This is a very dangerous problem as it has caused countless near misses in my car. Ford knows of the issue and that it disables the abs system but will not fix the problem. It does however offer to replace the part for over $1000.

This problem has happened to me twice already. The first time, the abs brakes engaged after driving over some water on the highway. The brake pedal got soft, went down almost to the floor, and did not reset itself. I was afraid to drive with the decreased braking power. I called a Ford dealer and they said they had never heard of this problem, although I could hear some snickering in the background. I told them I found forum after forum online of other Fusion owners complaining of the very same thing. They could only offer an appointment in 2. 5 weeks to take a look at it. I called an independent garage and a mechanic looked at it the same day, checked a few things and added some brake fluid to the master cylinder (mc). The braking power returned. He said I would need a new mc if it happened again. A few weeks later it happened again. The abs brakes engaged after I braked to avoid a car making a surprise turn in front of me. The brake pedal went to the floor and became soft. It felt like I had no braking power at all. I had to press the brake pedal extremely hard in order to slow down or stop. I got off the highway and kept pumping the brake pedal repeatedly to get it to reset. After a few attempts, it reset itself to its normal position. I took the car to a Ford dealer a few days later. They could get the abs to engage, but could not recreate the problem with the brake pedal going to the floor. They did not know what to do, and could only offer a $2000 "fix" they would not guarantee. I did not take them up on their offer, and they did not believe changing the master cylinder would correct the problem. The problem could occur again any time the abs is activated.

The brakes on my 2010 Ford Fusion go to the floor and I need to pump them continuously to get my car to stop. When it first happened I took it to a shop and they said it did not have brake fluid. I had my brakes flushed and brake fluid added. The brakes were good for about two weeks and then they again went to the floor. I took them into a brake shop and they did a reverse bleed, checked my pads, my abs system, my master cylinder, flushed them again and did not find any leaks or any problems. My brakes worked for about two days and then it happened again. Now it is a daily occurrence and I do not know what to do other than replace the m/c which I have been told is not bad. No leaking behind it or around it. I am at a loss. Something is wrong with my brakes and I have read that other 2010 Ford Fusion owners have had this problem.

The contact owns a 2008 Ford Fusion. The contact stated that while driving 20 mph, the brakes failed. The contact was able to stop the vehicle. The vehicle was taken to an independent mechanic for diagnosis where it was stated that the master cylinder needed to be replaced. The vehicle was not repaired and the manufacturer was not notified. The approximate failure mileage was 28,000.

When backing out of a parking spot I depressed the brake pedal and it went straight to the floor. The car did not stop. I put car immediately into park and then pumped brakes. Pressure seemed to return to the brakes so I proceeded to back out again, testing brakes consistently. Brakes seemed to respond but seemed "soft" still. I drove car to mechanic without incident, thinking the problem was the master cylinder. Mechanic informed me that the problem was not the master cylinder but rather the abs hydraulic control module and that he had seen this same problem with four other Ford vehicles, two of them Fusions. Mechanic stated that when he looked up the symptoms I reported to him in his "identifix/oem" database that this problem came up associated with a technical service bulletin from Ford, including the instructions for how to repair the problem. He could not find a recall notice for this problem, however. This appears to be a manufacturer's defect and I am perplexed as to why there is no recall. I will be contacting the Ford motor company to investigate further. My mechanic repaired the problem which cost just over $2000 and did include him taking the car to a Ford dealer to reset the abs and associate the repair with my VIN. Two days since repair and I have not had any brake problems.

Was driving and as I went around a corner, the brake pedal (which was slightly depressed) went completely to the floor. Lost all pressure. I pulled into a parking lot. Turned car off and back on. Gradually pressure resumed. Drove another day or so and it happened again while I was going straight. I went to the dealer. Had my master cylinder, brakes, rotors, and brake booster all replaced. That was the beginning of September. Now in December, it is happening again.

While driving around 25 to 30 mph on wet roads in stop and go traffic, I was braking normally and my right front tire was over a man hole cover. The abs engaged and the pedal went to the floor. The brakes have never returned to a normal feel. I've had the master cylinder replaced and brakes bled on numerous occasions and was finally told that the abs valve module was stuck open. I was quoted over $1,000 by Ford dealership. Can't afford it so I've learned to live with a spongy brake pedal. I just pray I don't need to stop suddenly.

When coming to a sudden stop and pressing hard on the brake pedal, the pedal went all the way to the floor and the abs system rapidly pumped. Since the car was not stopping like it should I had to pump the pedal again to finally get the car stopped. After this I had to depress the pedal nearly to the floor to properly brake the car. Checking brake fluid level I found it was normal. The first auto repair shop changed the master cylinder, found no improvement, and re-installed the original master cylinder. The second auto repair shop stated it required authorized Ford dealer to communicate with a "solenoid" to clear the problem. The third auto repair (a Ford dealer) stated no problem found without major dis-assembly and likely $$$ to fix. However the brakes worked a little better but still "mushy" when depressing the pedal. There have been multiple times when braking hard on a rough road the abs rapidly pumps with worsening of braking. It generally recovers somewhat over time but still too "mushy" for a normal braking. Ex-Ford repair man suggested checking recalls and have found similar experiences on this website. Surprised to find no recall yet.

The vehicle would randomly lose its breaking efficiency. The brake pedal would go all the way to the floor and would require 3 times more distance to stop. The vehicle was taken to a Ford service center for repairs. The correction completed included: test drive, found brake pedal is low due to air in the system, check for leaks, found master cylinder is leaking on the inside, replaced master cylinder, bleed brake system, perform abs system bleed and retest. Then again on 02/14/2012 the issue reappeared without warning. Took vehicle back to Ford service center and the following corrections were completed. Test drive, cannot duplicate customers concerns at this time. (service center advised me that they bleed the brake, but didn't list it out on the report. On 04/11/12 again had the same issue come expectantly. Took the vehicle to a Ford service center and the following corrections were made. Found brake pedal goes to the floor and car does not stop very well. Found abs valve is stuck open, r&r abs module, replace hcu, bleed brake system, perform abs system bleed, bleed brake system again and retest.

Brake pedal went all the way to the floor. Driving on the street about 25-30 miles per hour when brake was pressed and it went all the way to the floor with no warning or lights popping up. Took the car to the dealer where they diagnosed it with the need for the master cylinder to be replaced, calipers serviced and system bleed. That did not solve the problem and I left with an unsafe vehicle and with my 2 year old son in the vehicle. Took the car back and after 5 days they told us that we need a new hydraulic control unit. The cost for the repairs is over $2000. Manufacturer was made aware of the issue since there are other customers complaining about the same issue and they have the exact same vehicle. A recall is needed for this issued since it's unsafe and someone can get hurt without any signs. Manufacturer is not taking any responsibility for the cost of the repairs since there are no open recalls or warranties.
