Failure Date: 11/07/2014

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.

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.

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.

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.
