2022 Ford Mustang Mach E transmission problems

Filed Sep 28, 2026 · Driver assistance, Transmission · NY

My vehicle dash displayed "vehicle not in park" multiple times immediately after I put it in the drive position. At times I could push the "ok" prompt and proceed to drive but when I slowed or. stopped at intersections it would occur again and sometimes it applied the park brake without any action on my part. Around the same time I started getting "door module fault" or "door lock fault" warnings. It's been at a dealer over a month so I don't recall the exact wording now. The dealer diagnosed the vehicle and determined the door module fault made the vehicle think it was moving with the door open and replaced it. After the repair they're now saying it's unsafe to operate because while in their custody it's automatically applying the brake and displaying a "shift indicator module fault" that also requires replacement. They told me Ford doesn't offer coverage beyond the 3/36 basic warranty however it doesn't seem unreasonable to expect a shift mechanism to work for the life of a vehicle but certainly longer than 4 years. The dealer service advisor commented to me that he's seen these gear shift modules fail on several models including F150's as well as EV and combustion models. If this is a component known to fail across different models that posses a safety risk such as unexpected braking it could be an accident waiting to happen if it hasn't already.

The contact owns a 2022 Ford Mustang Mach-E. The contact stated that while driving at an undisclosed speed, the vehicle became inoperable and the vehicle stalled, and the gear shifter was inoperable. The contact exited the vehicle and was unable to re-enter the vehicle because the doors were locked and failed to unlock. The messages "Service Now" and "Battery Management" were displayed on the instrument panel. The pre-collision sensor warning light and several other unknown warning lights were illuminated. The failure had occurred on several occasions. The vehicle was towed to the residence, and the batteries were replaced. The contact researched the issue and became aware of an unknown recall; however, the VIN was not included. The vehicle was taken to a dealer, where it was determined that the battery management system needed to be reset. The vehicle was repaired, and the dealer advised the contact to drive the vehicle for 30-40 miles. However, after approximately 3 miles, the message "Stop Now" was displayed on the instrument panel, and the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 40,000.

On 6/4, I completed a long road trip of over 650 miles. When I got back into my vehicle to move it to where it would be parked for the night, it displayed messages for a Powertrain Malfunction/Reduced Power and a High Voltage Battery Warning. I powered the car off and back on within about 5 minutes, and the messages were still being displayed. I connected a code scanner to the car and the car had stored codes P0D0F and P0AA4. Both of these codes indicated a fault with the High Voltage Battery Junction Box, a known issue with the Mustang Mach E. I was able to drive the car to a dealer the next day without incident but am wary of trusting the vehicle to make the same trip back home.

File against: Ford Motor Company Vehicle: 2022 Ford Mustang Mach-E VIN: [XXX] Safety Complaint While driving, the vehicle unexpectedly slowed down, lost power, and became inoperable, creating a serious safety hazard. I was able to pull over safely, but the sudden loss of motive power occurred during active roadway conditions. Dealer diagnosis identified a wiring harness connector failure affecting communication between vehicle control modules. After the repair, the same issue reoccurred within one to two days, again causing loss of power. The vehicle is currently back at the dealership, and the underlying defect has not yet been permanently resolved. This recurring electrical failure represents a loss-of-motive-power safety risk that may indicate a broader wiring harness defect affecting vehicle reliability and safety.

I have a 2022 Mustang Mach-E GT and have now experienced two (2) High Voltage Battery Junction Box (HVJB) failures. First failure was in July 2023 when the vehicle had approximately 12,000 miles. I received the stop safely now message. Vehicle codes displayed via the Ford app showed a High Voltage Battery Warning and Power train Malfunction / Reduced Power warnings. I have now received this same failure and warnings again. The car currently has 54,000 miles and I was just advised by my dealer that the HVJB has failed a second time. My concern is that the replacement voltage boxes are nothing more than a Band-aid for the problem and not a permanent solution. As I prepare to receive by 3rd HVJB, I feel this is nothing more than a temporary fix until I receive another Stop Safely Now message while operating my vehicle. Please look into the HVJB failure rate for these vehicles. I am in online two Mustang Mach-E owners groups and this issue is rampant among owners. I feel this issue requires outside attention as Ford has now had 4 years to solve this issue for early produced Mach Es. Yet the issue continues to exist. Thank you for your attention in the matter.

I was driving my car when all of a sudden it lost all acceleration and power, I was lucky that I wasn't on the highway anymore and was able to pull over safely on a side street while car was rolling still. Dealer said 12V battery fused, and I have been reading forums where this is a common issue.. In a normal ICE car when 12V battery dies while driving, car can still drive, in this case, it just stops and pops up a dozen errors about everything being broken.

At highway speeds, the power brakes failed. In order to slow the car down, the brakes pedal had to be modulated with extreme force, upwards of 100 pounds of pressure on the brake pedal. As this happened, the car raised 4 Active Alerts - Powertrain Malfunction / Reduced Power - Antilock Brake Fault - Hill Start Assist Warning - Pre-Collision Assist Not Available. It took a lot of force and distance to bring the car safely to a stop. After 20 minutes we restarted the car and it began to operate normally. The car was brought to a nearby dealer immediately, however, the dealership is unable to diagnose nor replicate the problem. ***We were extremely lucky there were no cars immediately in front of us, and that we have an extreme amount of room to stop. Had we been driving in traffic, there would have been an extremely high likelihood of an accident with injury.
