2021 FORD MUSTANG MACH E Electrical System Problems

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...

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...

Car stalled once while going to a military appt but started up 3 mins later. Car then made a noise then stalled out of nowhere on the highway at a slow speed in heavy traffic causing anxiety. vehicle then had me stranded waiting for a tow to find out it’s the HVJB .

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.

The contact owns a 2021 Ford Mustang Mach-E. The contact stated that the safety system occasionally became inoperable. The contact stated that the cable wires were damaged and caused the dropping of the camera after traveling over a bump in the roadway, and the safety features were not available. The camera dropped five to six times per hour. The blue cruise became inoperable, and the driver assistance was inoperable. The vehicle began to pull to the side of the road. There was no audible chime detected. There was an unknown warning light illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted but declined to repair the vehicle under warranty. The failure mileage was approximately 34,000.

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 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.

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.

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. The manufacturer was notified of the failure. The failure mileage was 60,600.

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.

My cameras will not work and the screen will be black. Anytime I reverse or come too close to an object the cameras will show, but since there is a problem with the camera wire the image is just a black screen. This is a serious safety issue that Ford has yet to address and I have notified them about it, with an image and video of the problem.

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...

It has several error messages including "Stop safely now". This seems to be the same issue as recall 23S56 (TSB 22-2178). The vehicle is not drivable as it will not start or go into gear. Seems to be known issue with the HVBJB.

The contact owns a 2021 Ford Mustang Mach-E. The contact stated while driving 60 MPH, the messages "Power Train Malfunction - Reduced Power", "High Voltage Battery Warning", and another message to “Stop the vehicle as soon as possible because the vehicle may shut down without further warning” were displayed. The contact was able to pull to the side of the road. The contact was able to restart the vehicle and continued driving at 35 MPH. The vehicle was taken to the dealer but was not yet diagnosed or repaired. The contact related the failure to NHTSA Campaign Number: 23V687000 (Electrical System); however, the VIN was not included. The manufacturer was notified of the failure. The failure mileage was approximately 41,000.

Front Camera Fault & Pre-Collision Assist Not Available Errors COLLISION WARN MALFUNCTION, COLLISION WARN NOT AVAILABLE or COLLISION WARN DISPLAY FAULT. Over 30k miles in the car so the warranty is over for bumper to bumper coverage. Dealer said an update would fix the issue. It cost 2k. Paid. The error came back within a day. Dealer says the next option is to replace all the wiring for the cameras. Which would be another 2-3k.

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.

Front camera stopped working after a long period of working intermittently (started to happen after passing warranty at 30,000 miles). Without that camera many safety features are disabled, like a front collision warning, lane departure, cruise control with adoptive speed, emergency breaking. The cable and processor issue was confirmed by Ford dealership service.

The contact owns a 2021 Ford Mustang Mach-E. The contact stated that while the vehicle was parked, the contact became aware that the cruise control had inadvertently been engaged, causing the vehicle to accelerate. There was no warning light illuminated. The contact depressed the brake pedal to stop the vehicle. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 30,000.

Received intermittent warnings that the front collision warning system, cruise control and front camera were not working. The problem I think began after having my roof/windshield removed/reglued under recall. It was intermittent and I could not tell if software updates were resolving the problem, but then the problem became permanent at which time my car was out of warranty. Which does not seem fair since the problem began during the warranty period,. likely as a result of the windshield recall.

Forward camera failure, will not reset, continues to come up since 2021 multiple times this vehicle has been in the shop for this repair now that the warranty is over it is not covered and is not getting fixed I cannot use my cruise control and it continues to come up on the dash. This needs to be repaired and no one wants to fix it

Received a front camera fault warning in the car. The fault disables the safety feature of pre-collision-collision assist. Had an independent service center check it out, they let me know there is a TSB from ford. Waiting for the a scheduled appointment.

While driving I get a camera alert and a collision avoidance system is not working. Then I have to reset the system by pushing a button on the steering wheel. The car has been in for this problem 3 times since 2022 .Now the 3 year warranty is up and Ford won’t cover the repair. May dealership has been dealing with this issue on a lot of cars. I filed a lemon law suit. They are not going to repair the car or by it back. They to want to give a couple of thousand. But nobody can tell me what the cost will be to fix the car. So I am at a standstill

The instrument panel center display fell out of the housing today. Keep in mind this display controls things like all HVAC, defrosting, audio, rear cross traffic camera, and is the sole access to the front trunk (frunk). It looks like two seals on the top failed. When driving slightly inclined on a hill, it became detached and was dangling. This caused immediate distraction. The screen did not break. The screen fits back into the casing but there is no mechanism to attach it without complete permanent (ie superglue).

The fuse blew for the 12v power port (cigarette lighter type) in the back hatch area of our 2021 Mustang Mach E. We went to try and replace it. Couldn't find the fuse panel anywhere. Researched it online and discovered it was under plastic panels in the frunk. I didn't want to break a panel so I went to the local dealer. We removed 4 or 5 panels and finally found the fuse box but we still couldn't check or replace fuses. The fuse panel is mounted with the face with the fuses pointing away from you. There is a small panel you can open but this only exposes the back of the fuse box where the connectors are. The dealer couldn't do it either with casual help. They said I need to make an appointment for a technician to block some repair time to replace the blown fuse. This...

Driving in a 40mph zone and car suddenly lost all power followed by a message stop safetly now and the 12v battery icon. While coasting car lost power steering and upon stopping went into park and would not go into neutral for 30+ minutes

What component or system failed or malfunctioned, and is it available for inspection upon request? The front IPMA camera is faulty, not working. The dealership was able to diagnose it properly. How was your safety or the safety of others put at risk? The camera fault means that the vehicle safety features for front collision assistance and anything else that uses the front camera will NOT work. Has the problem been reproduced or confirmed by a dealer or independent service center? Bob Tomes Service center in Mckinney, TX has confirmed that the fault. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There are dashboard alerts for Front Camera Fault, and No Adapative Lane Assistance.

9 months ago I received a safety recall notice from Ford Motor Company regarding the Mustang Mach E battery terminals could possibly melt together at high speeds and that the car will lose power. Considering the severity of this issue I took it to a dealership right away where it sat unable to be fixed for over a month. They did not offer me a rental and having 2 kids and no car was devastating. I had to go pick the car back up without the recall being repaired and have had to use the vehicle in the meantime because I have no other option. I filed a case through the Ford BuyBack Program and was denied. I filed a complaint with the Better Business Bureau in hopes of a remedy or mediation with Ford and was also denied. I just called 3 dealerships this week after receiving a letter...

On April 19th, I picked up dinner and when I went to leave the parking lot, my vehicle turned on, but did not allow me to move out of park, nor shift into any other gear. I turned the vehicle on and off about ten times to see whether that might allow me to shift into another gear, but to no avail. It was later in the evening, so when I called the Ford customer service line I received an after hours message, and then thereafter I received a call from a Ford customer service center caller saying that they saw I was "stranded" and would send a tow truck to take the vehicle to the nearest Ford mechanic shop. They picked the vehicle up around 11pm in the evening. While the vehicle has had numerous other recalls, (windshield, etc.) I had not received any recall notice related to a...

I had my MME in to the local Ford dealership for recent work concerning Ford Recall 23S56 (HVBJB). This work was completed along with numerous other software updates needed as indicated by dealership service department. Shortly after getting car back a "1Pedal Drive Fault - Press Brake Pedal To Reduce Speed" warning message was displayed on the instrument panel and the one pedal function quit working. This feature reset it self after the car was parked overnight. Yesterday while driving over many miles this same warning message appeared to happen again and the one pedal feature quit. This happened while vehicle was traveling in an active school zone very near a crosswalk being used by students. This could have been a very bad situation if not quickly going from one pedal braking to two pedal braking which is needed to stop the car.

The contact owns a 2021 Ford Mustang Mach-E. The contact received notification of NHTSA Campaign Number: 23V687000 (Electrical System) however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and a case was opened. The contact had not experienced a failure. VIN tool confirms parts not available.

One pedal drive system failure. Had the 22B50 charge port recall done on the 18th of April 24. After leaving the dealer upon approach to a light one mile away, one pedal disengaged during de-acceleration for the light. Warning did come up near the same time. It felt like vehicle was accelerating, but just loss regen. It has since happened daily. sometimes multiple times. Restart the car and it works normal. The recall was to reprogram the BCCM according to the dealer.

On April 10, 2024, my vehicle experienced a warning message to service vehicle and a sudden loss of power while I was driving on the freeway. The issue was caused by a failure in my high voltage battery junction block. Something that Ford had already issued a software update vehicle to my vehicle for a recall. However clearly the software update was not an appropriate fix for the issue and should not be considered fulfillment of the recall. In fact, Ford has an open recall for the extended battery configuration of my vehicle to proactively replace this defective part. I am reporting this issue to the NHTSA because clearly the software ‘fix’ did not resolve the safety issue AND it’s scary that standard range batteries are neglected from the overall recall that applied to the rest of the model. Ford needs to be proactively addressing this issue for all affected...

The 2021 Mustang Mach-E has repeatedly shown these "Pre-Collision Assist" and "Front Camera Fault" errors ever since we got it 6 months ago. The errors can come and go multiple times during any drive. For my wife it is just an annoyance since she never uses Adaptive Cruise. But for me or anyone else using Adaptive Cruise, it becomes a safety concern because this error suddenly cancels the cruise and being an EV it begins regenerative breaking and slowing down much faster than other drivers expect while its driver must react as quickly as possible to return to pedal control. It's my understanding that this is starting to happen on many modern Ford vehicles at around this age and dealership service centers have been given guidance on fixing it. Ours has been in for this service and the error is still occurring.

While getting my recalls repaired at the dealership, I warned them of an issue my car was having with its front camera. I was receiving a “Pre-Collision Assist Not Available” notification each time I started my car. Upon investigation, the issue was described to me by the repair technician as. an internal failure IPM-A module on the car. This results in pre-collision no longer working on the vehicle along with the car no longer being able to utilize cruise control. The car is unable to detect vehicles in front of it to warn of a possible collision.

Twice in about a week my 12V battery has died without warning. The car is inoperable and there’s no way to open the car doors or even the trunk and front trunk. We’ve been locked out entirely. Left stranded in parking lots waiting for tow trucks. The only fix is jumping the vehicle’s 12V battery. If this happened while you’re in the vehicle you’d be stuck in the car since none of the accessory functions (including locks) function when this happens.
