The car I am having a issue with is with my moms 2009 Ford Fusion V6 SE with Sport Appearance Package. The car has 170,000 miles now. I am not sure if the car has Advance Trac, but it does have ABS. I am having a intermittent braking problem that has happened twice now in the past month. Both times happened on the highway and she said that when she hit the brake pedal that it damn near went straight to the floor and the car did not stop very well. After that she pumped the brake pedal and the brakes returned to normal. I looked at the car and the brake fluid level it full and clean. I cant find any external leaks. I just put new pads on the car not to long ago. My first thought with the brake issue was the master cylinder leaking internally but after reading some stuff on the internet it seems that may not be the problem but rather the ABS control unit. Also, there is no known codes or idiot lights at all. I don't really want to just start throwing parts at the car and wasting time and money.
Any ideas?
