Abs light came on and brake system failed to stop the vehicle until pressed hard the brake pedal. The abs light comes on and off.

Abs warning light comes on and check brake system message comes on at anytime while driving on sitting still. Lose braking power, causing driver to push brake very hard to stop and brake pedal sometimes goes to the floor and you have to use emergency brake to stop. Dealer couldn't look at the car for three weeks said its okay to drive in "manual mode", however manual mode only uses rear brakes and will take vehicle a long distance to stop in rainy conditions. (I went through a busy intersection in the rain and almost had an accident so left it at the dealer). Dealer had vehicle for almost six weeks, replaced the abs huc twice, finally called Ford. Ford advised to replace all brake hoses "due to restrictions". Dealers are telling owners they have to replace abs hcu and part alone cost $4700. 00. However, Ford knows of the problem and is not putting out a bulletin or recall, until someone gets killed. Owners are trading the unsafe car because the dealer is misdiagnosing the real problem which cost approximately $300. 00.

Upon startup and sometimes when driving the abs warning light will illuminate along with the service brake system and the regenerative brake system shutdown. Causing the brakes to become weak and ineffective.

April 2016 the abs light was on along with the message "check brake system and the regen brakes. " when breaking the vehicle took much longer than normal to slow and stop. The repair for this was $4100 ($4800 with labor). I was advised that this was a safety issue since the brakes were not working properly and to not drive the vehicle. I chose to have the repair since I need the vehicle for work and still owe money on it. I did some research and it apears that this is a known problem as other complaints on NHTSA and other forums attest to. I contacted Ford and asked that I be reimbursed as this is a safety issue. They declined my request.
