Power Steering Pump problems of the 2014 BMW 328

Vehicle cruising at 70mph on the freeway when the car stalled out with no warning. It simply went into neutral and cut the engine, rendering the vehicle hard to control since power steering and braking were not working. The car broke down again without warning on a city surface street with a speed limit of 45mph. Independent mechanic diagnosed that the high pressure fuel pump imploded, sending metal throughout the entire fuel system. Again there was no warning and braking/steering were affected.
