Brake Abs Warning Light problems of the 2011 Ford Fusion

Ii was in a parking lot and pressed on the brake pedal and it went to the floor and did not stop the car. I had to pump the brake pedal to get the car to stop. I had to continue to pump the brakes any time I tried to slow down or stop the rest of the way home. I stopped driving the car as the brakes are now unreliable but I am taking it in to the dealer today for repair. When the brakes stopped working the abs light came on.

In August 2016, I cranked my car (a 2011 Ford Fusion hybrid) in my driveway and noticed the service advancetrac, brake failure system, and abs lights lit up on the dash. I tried to back out and notcied the electric break were not working and the break peddle was to the floor and difficult to press. The car was towed to a Ford dealer. They kept the car for a week and could not find a probelm. The lights went off and the probelm was resolved on its own. In August 2019, this probelm happened again. I cranked the car in a parking lot and noticed the same warning lights from 3 years ago were on. I was able to get home, but the brakes were not very responsive and were significiantly further down than usual. I took the car to a Ford dealership and they claimed they "reset the system" and the problem was resolved. A few weeks later, the issue reoccured. The dealership said they did not know how to relsove the problem. After about 4 days the warning lights went off and the brakes returned to normal. On October 20, 2019 the warning lights came on again and the issue is still occuring. The car is drivable, but it does not feel safe. It could not come to an abrupt stop if needed and I live on a highway where people often pull out in front of me. In 2009, Ford issued a software update for the brake system for Fusion hybrids. It seems later hybrid models also need a software update. I have read that replacing the brakes or abs control module does not reslove the probelm. It is an issue with the computer system.

The abs light and the traction control light comes on when starting car and chimes and the service traction control is displayed on dash. Then when starting to drive and stopping brake pedal seams soft. After driving about a mile the lights go off and braking is normal. It seams like it's the abs control. There has bean a recall on earlier model years to replace abs control assembly.

Both rear driver and passenger brakes are simultaneously wearing down within 2 weeks of standard use. Outer pad wears twice as fast as inner for both calipers. Pads and rotors changed twice. Calipers tested without issue. Pad wear is severely uneven. Others online have noted faulty abs modules from Ford. Spongy brake pedal. Occasionally brakes get stuck on rear. Front brakes operate without issue or abnormalities. Issues began after abs light flashed while driving.

After abs activation brake pedal goes to floor with greatly reduced braking effectiveness. No abs fault light. Recall on earlier model years.

At least three times on separate occasions, abs warning lights came on and engaged suddenly while there was a loss of braking power. Brakes were spongy and could barely stop the car. Trouble codes c00002 c0022, c1012, u0415 and u30000 codes showed. My mechanics checked my mechanical brake systems and all were fine and found no problem. My mechanic thinks a computer problem is the issue. I took car to local Ford dealer and they found no braking problem.
