2021 FORD MUSTANG MACH E Complaints

Was driving home and stoped at a business with no issues. Return to car to operate and car not functioning properly. Getting error light “Stop safely now”. Car will not start with power button, will only go into full accessory power mode. The car cannot be switched from park to anything else. R, N, D not accessible. It seems that a system update was recently pushed to the vehicle.

On 4/1, while entering the FWY @ about 50 mph under moderate accel, big thump (felt like the trans fell out), drivers display cycled thru multiple errors with "stop safely now" repeatedly flashing. Throttle went dead, speed dropped to 35 and steadily decreased. Was able to slowly exit FWY @ next exit, rolled thru light @ bottom of ramp and pulled over to the side of a busy side street. Came to a stop & car would not move. Put in park, cycled on/off several times. Would not come out of park. Tow truck arrived. Found emergency tow function in the main display. Tow driver hooked up front, put rears on dolly & towed to dealer.

The contact owns a 2021 Ford Mustang Mach E. The contact received notification of NHTSA Campaign Number: 21V711000 (Visibility) however, the part to do the recall repair was not yet available. The dealer was made aware of the issue. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

The 12V battery drains to the point the car will not boot or go in gear. It spits about 8 error messages at you but none that say low 12V battery. This has now happened 3 times in the last year. This has left me stranded in the cold hundreds of miles from home one of those times. They are now saying that a high voltage junction box and a battery energy control module is required. After waiting 4 months for parts we will see soon I am hoping. Noted in additional details the first time it happened is referenced. OBD 2 ============1============== P0AA2 Raw code: 0AA2 ECU: 7EC Status: Confirmed OBDII: Hybrid battery positive contactor - circuit stuck open ============2============== U0594 Raw code: C594 ECU: 7EC Status: Confirmed OBDII: Invalid data received from hybrid powertrain control module

Car was parked in my home garage and would not start, displaying "Stop safely now." Vehicle appears to have code P0AA1 Hybrid battery positive contactor - circuit stuck closed. Many other Mach-E vechicles are exhibiting this defective part in the high voltage battery system, which appears to be the Battery Electrical Control Module (BECM). Ford appears to be aware of this issue, and, unconfirmed, has stopped production of the Mach-E to canibalize parts to fix vehicles that fail. However, some are less lucky than me and had their car stop dead while driving on the highway, and Ford should not be waiting for vehicles to stop and strand people before fixing this serious defect.

The vehicle displayed "Stop Safely Now" on the instrument panel and would not drive. Required a tow to the dealer, High Voltage Battery removal, replacement of the High Voltage Battery Junction Box, and vehicle reassembly.

As the vehicle was braking to a stop at a stoplight the rear motors began chattering. The vehicle stopped and gave multiple error messages including "Shift System Fault" and "Stop Vehicle Safely." It locked the parking brake and could not be moved. It was stuck in the middle of a busy intersection on a county highway. It could not be driven or pushed out of traffic until the error cleared. It was a hazard to the occupants and other drivers on the road. 911 was called to get support with traffic. There was no indication before this failure occurred. It will be going in for service in 2 days. This is the second occurrence of the failure on this vehicle, the previous one at 2011 miles.

The dealer was able to confirm that the error codes had occurred but could not reproduce the failure and made no specific fixes other than replugging electrical harnesses..

Found when friends were sitting in the backseat that the seatbelt retractors were not functioning correctly. Upon further investigation, we found that one had a slight tear in it and then she was trying to pull the retractor out and releasing it to get it to cross her chest it ripped right out of the mechanism. I took a look at the other side and noticed that there was some fraying on the seat belt and this too must've been damaged by the mechanism. Both seatbelts are now considered not usable one completely tore out of the mechanism. Opening Ford replace

No clear sound or indication when BlueCruise disengages leading to unexpected behavior.
