Vehicle was stopped on a steep city street behind another vehicle turning left. Vehicle went to move forward and turn left and it shut off and rolled backwards down the steep hill. Wheel could not be turned, brakes could not be pressed, when gas was pressed it did not go forward, it rolled backwards it was like it shut off after being in auto stop mode. Parking brake assist came on automatically and vehicle rolled into a cement pole. Vehicle was able to be restarted. Parking brake would not release. Had to shut off vehicle, restart and tried to release parking brake 5 more times before it released. This vehicle often rolls backwards after being in auto stop mode and the gas needs to be pushed hard in order for it to go forward. This vehicle feels like it slows down when pressing the gas at times and you need to push the gas pedal harder. The brakes squeak often when wet and cold and sometimes when starting the vehicle the brake will not allow you to push it down, you have to push it several times, let up and push it again before the vehicle will start.
