Failure Date: 10/26/2015

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.

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.

Its the abs. I have changed the brakes gotten new master cylinder and I still cannot get full brake control. Still pushing pedal almost to the floor. My mechanic checked on this site which showed others with same problem. Which he stated is a factory defect.

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.

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.
