Loss on all braking systems. Multiple warning lights including on dash. Brakes will become spongy and not stop or lock up all 4 wheels at slightest touch. Taken to dealer who provided a service memo SSM 53683 which basically says vehicle unable to power down and no fix available. Ford is aware of the problem and has done nothing to fix this despite multiple phone calls and emails. This is a significant safety issue Vehicle is also brand new will less than 1000 miles on it
