ABS brake light warning came on. Brakes pretty much stopped working without any prior warning to the lights. Had to depress the pedal all the way to get brakes. Very unsafe. Now the brake is stuck on and the car doesn't move. Have talked to and read about several people that had the same issue. Why hasn't there been a recall yet?Owner report · Service Brakes · May 2019

Stop safely now chimes and displayed on dash followed by no acceleration until vehicle stalls and stops.starts right back up but continues to happen especially in la rush hour traffic. Very dangerous! Had recall work done on the mecs 3yrs ago but problem has continued. This happens while in motion on the 110 freeway in downtown los angleles, ca. Could be the electric throttle body or rear actuator. Or any other component that works with the electric motor and battery.Owner report · Electrical System · Dec 2018
Car has been rock solid reliable up until 3 weeks ago. Driving normally on city streets the car abruptly shut down the hybrid and ice propulsion units. Steering froze up and it was like putting the brakes on it stranded me in the middle of traffic causing delays for other drivers and a dangerous obstruction. The car has no limp mode to allow for safely getting out of traffic. It had to be towed. Ford dealer has had car for 3 weeks and are still uncertain as to what caused the unsafe shutdown.Owner report · Fuel/Propulsion System · Oct 2018
