2021 Ford Mustang Mach E Electrical Problems

While merging onto the freeway and accelerating, the center touchscreen detached from its mount. The screen has two components: a rear housing fixed to the dash and a glass front panel that sits on top of it — the glass panel came loose on its own; I have never attempted to remove or pry it. The panel remained connected only by internal wiring and hung loose from the dash while the vehicle was in motion. This created three distinct safety hazards: (1) the screen was dangling and at risk of fully detaching, (2) the failure occurred during a high-attention driving maneuver (accelerating while merging), and (3) I was forced to catch the glass panel with one hand to prevent it from falling or shattering, then reattach it while still navigating traffic — as the sole occupant of the vehicle. Heavier-than-usual traffic that day gave me a lower-speed window to manage this; at highway speed under normal conditions, this could have been considerably more dangerous. No warning lights or dashboard messages preceded the failure — this is a hardware/mechanical defect, likely related to the internal mounting clips. Since the initial failure, the screen has detached repeatedly during acceleration, occurring frequently over the following days. In subsequent incidents, my boyfriend was a passenger and able to assist in stabilizing the screen. The screen has since stopped functioning entirely, which independently constitutes a safety issue, as it disables the backup camera display and other driver-assist systems that rely on it. The dealer has not yet been able to reproduce the issue. A service appointment has been scheduled and is pending.

The HVBJB ($3500 + Tax) went on my car. It is out of battery system warranty by 25,000 miles (ended at 100,000 miles, I have 125,000 miles). I called Ford Corporate and they said they "have no current programs" to give me any good will discount on the repair. This is a big, known issue with Mustang Mach-e's There was a recall for this HVBJB part / system on many of the 2021 models, but somehow mine wasn't included in the recall. I cannot afford this repair, and I was hoping the NHTSA can get involved to get me some financial relief from Ford. There was also a safety issue as this morning when this all happened, the car forced me to stop at an intersection and would not move or restart. The police had to push me through the intersection. It's currently at Chapman Ford in Egg Harbour Townshop, NJ.

This is a safety issue. The front collision assist is not working. I have returned the car to the Ford Dealer (Biener Ford) several times but the dangerous issue persists. I'm not the only one. There are many complaints listed on the web and the Ford Mach E forum. Ford needs to recall their EV Ford Mach-E vehicles and fix this dangerous safety issue once and for all.

The car gives two messages, "Front Camera Fault Service Required" and "Pre-Collision assist not available." The cruise control does not work, however, the front camera does work. I had the vehicle scan done at the Ford dealer and was told it needs a 7 hour software update, after which it may need cables replaced. I do not understand how software goes bad. I do understand something may have happened to cables but that would not be checked until they had charged me $ 1,400 for a software update. This is a safety issue and, from what I read on the Mach E forum, is not where near unique to my vehicle.

Vehicle experienced immediate loss of motive power while in motion at 45 mph after "Stop Safely Now" alert. This is a repeat power failure. The vehicle was in service for 75+ days (Dec-Feb) for this exact defect. The Ford service center said they replaced the “battery controller” yet the issue recurred. The car previously flagged this alert while in motion 2 times prior (one on the highway going ~65mph and on another major street going roughly ~45 mph). As a Ford Reacquired Vehicle (Buyback), the failure to resolve this catastrophic electrical fault creates an extreme risk of crash and entrapment in traffic, putting myself, my family and the drivers in vicinity at significant safety risk. The car is currently at a different Ford Service Center. They have been able to reproduce the issue and are currently running diagnostics to identify a resolution.

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.

I am requesting immediate escalation regarding my 2021 Ford Mustang Mach-E (VIN: [XXX] ), which is currently undrivable due to being stuck in “Power Accessory Active” mode. The vehicle will not enter Drive. The dealer has diagnosed DCEM / high-voltage system-related faults and stated that recall repairs cannot be completed unless I first pay approximately $3,000 to repair the “main battery.” My concern is that the symptoms and failure mode exactly match the known High-Voltage Battery Junction Box / DCEM defect described in Ford Safety Recall 23S56, including: •Vehicle unable to drive •High-voltage system refusing to close contactors •Vehicle remaining in accessory power mode •Safety-related loss of motive power While my VIN may not be currently listed as eligible for these recalls, my vehicle is exhibiting identical symptoms and failure modes associated with the following Ford safety recalls: •HV Battery Junction Box / DCEM defect (Recall 23S56) •Powertrain / Software Update (Recall 22S29) •12-Volt Battery / Door Latch Entrapment Risk (Recall 25S65) It is important to note that other Mustang Mach-E owners have reported the same recall-related failures even when their VINs were not listed for these recalls. These failures involve contactor issues, loss of motive power, and vehicles being stuck in accessory mode — identical to the symptoms my vehicle is experiencing. Given that my vehicle is experiencing a safety-related loss of motive power, Given the safety implications and known defect history, I request that this matter be reviewed.

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

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.

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.

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 electrical system failed. Issue was it disengaged the 12 volt system as well. Vehicle seized and stopped in the middle of a high usage road with no ability to put into neutral. After speaking with Ford, they concede that there must be 12 volt battery power in order to put car in neutral. After 2 hours of blocking traffic The tow truck arrived ( was a rainy day) and within a minute hooked up a 12 volt battery and drove the vehicle off the road way. This is not acceptable and needs to be addressed. My claim number with Ford is: case [XXX]. Thank you. Feel free to contact me in any further information is needed.
