Brake Fluid Leak problems of the 2009 Ford Fusion

I was moving about 40mph going straight and when I hit the brakes to turn they went to the floor applying no braking action at all. I was lucky that I was going straight on a country road with no traffic or this could have been catastrophic. There are no brake fluid leaks, pads have maybe 15,000 miles on them and are good. There were no warning lights illuminated in the car. Several months back after the abs was activated the brakes got soft and reset after the car was shut off and sat for a while. There were literally no brakes whatsoever today. After letting the car sit for a while turned off the brakes are back, but the pedal is still soft and I don't want to test drive the car as it is too dangerous. This appears to be a common problem from looking at various web pages that should be addressed ASAP.

Driving car in inclement weather. Was going forward ( straight) on a local road with a downhill grade at a speed of approximately 15 mph. Used brake to maintain speed as I was going down the hill. The abs engaged briefly as expected due to snow on the road. Removed foot from brake briefly but when I stepped on the brake again to stop at the stop sign the brake did not engage as it usually does but instead went almost all the way to the floor before engaging. Stopping distance was significantly longer that usual. If I had not allowed extra stopping distance as a precaution due to the weather I would have driven through the stop sign on to a busy road. Once stopped I turned left onto a flat straight road. As I drove forward going approximately 25 mph I tested the brakes 4 additional times over a distance of approximately a mile and a half. Each time the brake petal went almost to the floor before it engaged. When it did engage it took much longer to slow the car down. I pulled into a flat parking lot and called a family member to check the area where the car was parked for evidence of a brake fluid leak. There was none. I kept the car running for approximately 10 - 15 minutes thinking the issue might be related to the cold ( it was about 20 degree fahrenheit). After allowing the car to run I tested the breaking again by accelerating and stopping in the parking lot. The brakes appeared to be working as usual. I am having the vehicle towed to the dealership as I feel it is unsafe to drive.

Driving at about 35 mph going straight, I stepped on the brakes so that I could turn, snow/ice covered roads, abs engaged. I continued on driving after that at about 45 mph, went to stop to turn into my driveway and the pedal went to the floor with no brake action at all. No fluid leaks,no warning lights on the dash, pads had maybe 25k miles on them, everything was working fine until the abs engaged on my first turn. A few months back, after the abs was activated the brakes got soft/spongy. After the car was shut off and sat for a while, the brakes reset. Today, my car felt like it had no brakes. This appears to be a common problem from some of the research I have done online.

After anti-lock brakes engaged while driving, the brake pedal went all the way to the floor and lost most of the braking ability. This happened 3 times. The first 2 times it happened, the braking pressure recovered within a day and brakes went back to normal. The 3rd time it happened the brake pressure never recovered completely. I still have braking ability, but requires a long brake pedal travel to engage brakes fully. If I pump brakes, pedal pressure seems to build to a normal level, but will go back to a soft feel immediately after I stop pumping (as if the brake fluid is leaking past something internally). Had dealer look at it after 1st incident, but couldn't diagnose any problems with system (brakes had gone back to normal by then). I am currently driving with the long pedal travel and soft feel of the brakes, but have learned to compensate for it.
