2021 Ford Mustang Mach-E Electrical System Problems

While charging my electric vehicle with this Enel X JuiceBox 40 charger, a burning plastic smell was noted. Upon examining the Enel X charger plug that was attached to my home's NEMA 14-50, it appeared partially melted and very to touch. Using a towel, the plug was removed and a small fire and sparks flew out of the NEMA outlet. The right half of the outlet's plastic shell was melted and the inner metal was charred. Same charring and melting was noted on the corresponding side of the Enel X plug. I turned the circuit breaker off and the sparks and fire subsided. Model of JuiceBox: 2JBO401RNA-PJWX-300

After recall-related software updates were performed on my 2021 Ford Mustang Mach-E, the vehicle began experiencing repeated electrical and climate control failures. The heating and defrost system stopped working, leaving the vehicle without heat and causing the windows to fog, which reduces visibility in cold weather and creates unsafe driving conditions. The vehicle has been taken to multiple authorized Ford dealerships for inspection and repair; however, the problem returned immediately after the repair. The issue was reproduced and confirmed by a second dealer. A required part is currently on back order until the end of Feburary, leaving the vehicle unrepaired for an extended period. In addition, the vehicle experienced 12-volt battery failure and slow charging after the last recall update. These issues were not present prior to the recall. There were no warning lights before the failures occurred. During severe winter weather conditions in Pennsylvania, the lack of heat and defrost made it extremely difficult and unsafe to operate the vehicle. Because of reduced visibility and freezing interior temperatures, the vehicle could not be safely driven and, due to frigid temperatures, has remained parked. I am still making monthly payments on a vehicle that cannot be reliably or safely used.

On [XXX], my 2021 Ford Mustang Mach-E (VIN [XXX] ) experienced a complete electrical failure related to its V12 battery system. The vehicle required roadside assistance twice during the same service call — first to jump the car to release the hood latch and again to restore enough power to unlock the doors. An elderly occupant was trapped inside until power was restored. After exiting, she became light-headed and fell; EMS responded and transported her to the hospital. This represents a serious safety defect because total electrical shutdown prevented door operation and normal egress. I am requesting investigation and possible recall review.

Car gave me a warning to bring car to dealer, who told me I need to replace the High Voltage Battery Junction Box. This part was recalled on other models, but not my specific model, despite the cars using the same part. Dealer said it will cost $3,593 to replace and Ford customer service says there is no recall for it. Also, I intermittenly have gotten a warning that the front camera will not work for forward collision warning or cruise control. It often happens after a bump in the road, but also happens at other random times.

My 12-volt battery died and due to my car being an Electric Vehicle there was no way for me to get inside my car without jumper cables. The safety concern was that it happened without noticed when i stepped out the car to get my [XXX] out of the back seat. Completely locking me out the car and no way to get inside. The car doesn’t have a conventional door handle and cannot open without electricity. I had to have emergency services come and break into the car.

Melted High Volt Junction Box after DC Fast Charging. Car became compromised while 3 hours from home. Limiting speed and ability to recharge. This vehicle had the High Voltage Junction Box melt back in the summer of 2022. The original was replaced under Warranty. The replacement part they installed is also faulty. I do not DC Fast charge very often. Maybe 12 times in the lifespan of this car. The original recall for this issue was a Software upgrade in the summer of 2022. There appears to have been a recall for hardware in fall of 2023 but for some reason this car was not part of that recall. The part that Ford installed in July of 2022 has since been redesigned several times, but I was left with the old version and that Melted down. Please recall the faulty HVJB part installed in these cars that were impacted when the originals melted. This costs $3,000 to have them repair and is not covered by warranty any longer.

The car was parked and will not move. The car turns on, an alert displays that to stop the car and pull over and the car is in park and will not allow you to move the dial out of park. Had to have the car towed to dealership. The 12v battery was replaced, this did not help, the car still will not allow you to put it in drive.

Some of the driver assistance warning systems may not be operable due to multiple and frequent warning messages. Messages are: Front Camera Fault Service Required; Pre-Collision Assist Not Available; Lane Keeping System Fault Service Required. Ford is unable to correct these making it potentially unsafe. Additionally, they are not covering the attempt to fix this under the extended warranty. There are hundreds (if not thousands) of owners of the same model and year of my car, and subsequent years as well, having this issue with no resolution. There needs to be a recall.

The contact owns a 2021 Ford Mustang Mach-E. The contact stated that while driving at approximately 20 MPH, the infotainment screen flipped forward and opened. The vehicle was taken to a dealer where it was diagnosed and determined the infotainment system screen needed to be replaced due to the clips malfunctioning. The vehicle was not repaired.

My vehicle is not a part of the Recall #23S56, however, my High Voltage Battery Junction Box has gone back and in need of replacement. The warranty light appeared on 2/2/25 after acceleration. I was able to make an appointment with my local Ford Dealership for today 2/4/25 and was informed of the issue.

The forward collision detection system failed first. Then the car suddenly would not move and gave a pull over immediately warning on the dash and also flashed a battery light. It was 15 degrees outside and my wife and son were stuck in the cold. Not a safe environment. This is inexcusable for a car to be driving fine on minute and to be completely inoperative the next.

The car had an issue with the 12V battery which caused it to be completely disabled and unresponsive to the key fob and phone as a key. My wife had gotten out of the car without knowing this had happened and went to the rear door to let out our infant son, but the door would not open. We called emergency services and roadside assistance. AAA arrived first and tried to open the lock but were unsuccessful. I had to smash the window to open the door and rescue my son. Emergency services arrived after I had already done this. The only reason I know it was an issue with the 12V battery is because the Ford dealership told me after I had the car towed there for inspection. The only way to open the car in this situation is to use a portable jumper to jump two wires hidden in the bumper which open the Frunk. Then you need to jump the actual battery that is located in the frunk. It does not have a mechanical release for the doors. This supposed fix is highly dangerous as it requires one to have a readily available jumper and the 12V battery needs to be completely drained in this scenario. In my case, this didn’t work even when the Ford technician arrived. The only possible way to get in was to break through a laminated glass window which was incredibly difficult to break even with the correct tool to do it.

For over a year I got this warning that said pre collision assist not available. And it would go away after a few minutes. A few weeks ago it never left. Now I have that error as well as adaptive cruise not available. I cannot use my cruise control. I just recently had another issue and paid over 3 thousand. Now ford wants to give me another quote for 3 thousand. I searched and I'm not the only one with issue. This should he a recall problem as we are all having same issue.
