Ok we have a big issue with a 2013 Ford Fusion that none of us can figure out. This model has the electronic parking brake. There is a switch inside the car that is supposed to engage and disengage the parking brake. The problem is that the parking brake will engage but not disengage. So right now t…

My problem with the EPB has similar symptoms. I get the Release Park Brake as soon as I turn on the ignition. If I release it, it actually locks up the EPB. I have to shut off the car to reset it. So I’m driving around with the brake light flashing and the beeper beeping for a few weeks now. I never…
