Brake booster needs to be replaced because it has failed, making the car unable to stop. This has caused the car to shut off if the brake pedal is pressed to long, like stopping at a stop light. The vehicle is in a Ford authorized service shop and has been confirmed as brake booster failure. The issue started with stalling, car throwing codes such as no oil, hissing in the brake lines, spongy brake pedal, leading to zero ability to stop. Issues started slowly around October and by January, the car is completely unable to stop.
