In owners’ own words

I went to start the vehicle and it gave me a red warning "stop safely now". It was already stopped and would not start at all. It had plenty of charge on the battery pack. It's been at the dealer for nearly two weeks and they have had to order the HVJBC, I believe.
The contact owns a 2021 Ford Mustang Mach-E. The contact stated while in reverse(R) and driving approximately 3 MPH, the vehicle would independently brake suddenly. The contact stated that the parking brake light was illuminated. The contact stated that the brake failure was intermittent and occurred without warning.
on 8/22/2022 received a powertrain malfunction notice by Ford. Since that time on four occasions the vehicle has lost power causing a significant jerking and loud thud. It loses all power. This has happened twice after Blue Cruise has disengaged. Two other times include when the vehicle was placed in drive or reverse.
Two problems on multiple separate occasions occurred. 1st problem - more than twenty (20) times car had suddenly accelerated or slowed down while driving with cruise control. This supposedly should have been resolved with an update that was downloaded around a month ago. Nothing changed, car still accelerates or slows down randomly.
Power loss a week ago. Had to have Mach E towed to dealership. Ford is aware of Mach E power loss
