2022 Ford Mustang Mach E Murrieta, CA

ENGINE

The high voltage battery junction box connector has failed. There have been two recalls one software and one to replace this part the high voltage battery junction box with a more robust part to handle thermal loads. As of now there are zero recalls on my car open so they are all done. The first time this component failed was around 24k miles ish it's now 56k miles ish and it has failed again even after two recalls and an investigation around the same exact time. This means one of two things has happened either somehow the recalls by Tim Moran ford where not done properly and somehow the older failed part number was installed in my car or the more likely senario is that fords supposed robust part was just a simple part number change without a robust enough design to handle the thermal load. I would like to think that Tim Moran ford who is independent from for has done there due diligence the first time it was replaced and but the correct part number which leads me to conclude the investigation by the NHSTA that resulted in a part change did not fix the issue at hand and the car is now unsafe to drive as this is the second time it has happened to me on this vehicle. Thank god this time I was not going through a curve and headed off road. Same issue almost exact same failure part gone wrong and same issue to date. I demand not only for myself but the safety of others as a former Quality Assurance Representative of electronics on Hueys and Cobras that this be re investigated immediately. It is to late in the game to have zero recalls on my car open two that have been done and the same part fails a second time this should never happen to anyone if it has already been investigated and supposedly fixed. I do not believe it is fixed and the car is not safe to drive I'm hesitant to even go get it when it's ready next week with this serious safety flaw in the design of this vehicle with it still incurring.

2022 Ford Mustang Mach E San Diego, CA

ENGINE

I am unsure, but I think it's the High Voltage Battery Junction Box. A week after buying the car used from Aaron Ford of Poway, I received a Safely Stop now warning, then the car broke down on the middle of the turning lane into my job a medical clinic putting myself, patients, other drivers, and my coworkers all on danger as it is a busy street. The hazard lights would not work, and the car would not go into neutral. The next day, all the dealership did was replace the 12v battery, then I only got 1 mile from the dealership before it broke down again in an even more busier and dangerous highway in the slow lane and crosswalk. The hazard lights would not work, and the car would not go into neutral.

2021 Ford Mustang Mach E Mount Laurel Township, NJ

ENGINE

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.

2021 Ford Mustang Mach E Chillicothe, OH

ENGINE

While driving my 2021 Ford Mustang Mach-E, the front electric drive unit failed suddenly with no warning signs, warning lights, unusual noises, or any prior indication of a problem. During the failure, multiple fault messages appeared on the instrument cluster, including warnings that disabled adaptive cruise control and indicated the all-wheel-drive system was no longer functioning. The vehicle began to vibrate severely, feeling as though it was driving over rumble strips. As I slowed down, the front of the vehicle became extremely clunky and exhibited abnormal drivetrain behavior. Shortly afterward, the vehicle became undrivable and could no longer be operated under its own power. It had to be towed to a Ford dealership, where I was informed that the front electric drive assembly had failed and required replacement. This is the second time this exact component has failed on the same vehicle. The first front electric drive assembly failed at approximately 33,000 miles and was replaced under warranty. The second failure occurred at approximately 102,000 miles with no warning. I believe this repeated and sudden failure of a critical drivetrain component presents a significant safety concern because it can leave drivers stranded without warning and results in an unexpected loss of propulsion while operating the vehicle in traffic.

2022 Ford Mustang Mach E Peoria, AZ

ENGINE

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.

2023 Ford Mustang Mach E Lebanon, MO

ENGINE

I’ve had this situation happen at least 2 to 3 times but specifically I’ll talk about the most recent. I was reversing out of my parking spot approximately 20 feet or so to where I can turn around and circle around the parking lot and exit. When I switched over to drive the vehicle accelerated rapidly unprompted. I was able to stop it by using the break, but I can also see how this could be a significant safety issue.

2023 Ford Mustang Mach E Lexington, SC Crash

ENGINE

I have a 2023 Mach e premium on lease.  
I drive using single pedal mode. 
Three days ago I pulled into a parking spot in front of a restaurant in a plaza. When I took my foot off the accelerator the car came to a complete stop (as it should have ) … about a half a second later, before I could put the transmission into park, the vehicle went full throttle and jolted forward up over the curb onto the plaza sidewalk and crashed into a full brick column. I slammed on the breaks as fast as I could, but if the brick column was not there, we would have crashed into the restaurant. There is damage to the front drivers side of the vehicle. The airbags did not deploy. The beeping sensors never went off. Honestly, the experience scared the crap out of me. We’re lucky no one was injured. 
Ford has the car at the dealership now. 
they told me that something seems to have malfunctioned. They told me that the car should have deployed the airbags, the sensors should have went off, a deceleration stamp should be logged in the vehicle data and it should be telling ford that the car experienced a collision. None of that happened. 
needless to say, they are now telling me that because they can’t mimic the problem, Ford is instructing them to return the vehicle to me. 
they have nothing to repair, and are not taking ownership for the damage. I honestly don’t want to take the car back. 
my wife isn’t comfortable driving it anymore as she feels it’s a safety risk.

2023 Ford Mustang Mach E Orlando, FL

ENGINE

I was driving along the road at 35 mph when the vehicle lost power and refused to accelerate or keep speed. The cluster flashed a warning indicating "Stop Safely Now", so I pulled over and came to a stop, and I shifted to P. Thereafter, the vehicle shut off and would not start, continuing to indicate to "Service Vehicle Now", as well as additional new errors, including "Service Powertrain", "Full Accessory Power", "Collision Assist Unavailable", and at least 8 other errors that would not go away. Two red lights were indicated on the cluster - one of them looks like a car with a "!" through it, and the other is a wrench. The vehicle is charged every night to 95% using a Level 2 CCS charger directly to the vehicle's charging port, no adapters. The vehicle had 91% battery remaining when this occurred. About 20 minutes after the incident, while waiting for a tow truck, the vehicle went completely dead and all components were unresponsive. The ignition would not activate, the doors would not open, and the open doors would not properly shut (the electronic catch mechanisms were not catching the door to keep it shut). I could not activate the screen to put it into Emergency Tow mode. The vehicle has 17,999 miles and was purchased brand new in September 2023 with 0 miles.

2023 Ford Mustang Mach E Laguna Hills, CA

ENGINE

Vehicle will suddenly without warning change driving "mode". This includes while in motion or when vehicle is parked, shut off, and re-started. I had submitted video of this occurring many times to the Ford Service Dealer. Vehicle will disengage from "One-Pedal Driving" mode without warning. This is a serious driving hazard because the normal "brake regen" feature to slow and stop the vehicle is suddenly no longer "engaged". Vehicle will no longer receive safety updates via vehicle OTA (over the air) updates to address these and other vehicle defects. The last OTA was in June 2024 with a regression/repeat update manually applied at the Ford Service Dealer in September 2024. The vehicle is now substantially out of date with respect to safety and other vehicle OTA updates. The Ford Service Dealer cannot repair these problems. They have attempted to address and repair without success, even claiming in Sept 2024 this vehicle was "road-tested" by their Technician, however the mileage on the odometer had not changed since the vehicle was left at the Ford Service Dealer. Lastly, regarding the active recall on the vehicle, 5 Ford Service Dealers in the area stated the NHTSA Recall is "unnecessary" and the manufacturer (Ford) knows the replacement parts are not available. Specifically, I was informed my vehicle would remain "parked" waiting for service for 4-6 weeks before any diagnosis or repairs would be made.

2022 Ford Mustang Mach E Agoura Hills, CA Crash

ENGINE

Car was stopped at the top of a hill. Driver put the car in park and exited to talk to a security guard to raise a security barrier. Car began to roll down a hill and didn't stop until it hit a metal security gate 250 yards away. Car was totaled as result of collision with gate. No one was hurt. It would appear that the transmission/engine did not stay in park and began to roll and that none of the other safety features stopped the car. There were no passengers in the car at the time of the accident and no airbags went off.

2021 Ford Mustang Mach E West Orange, NJ

ENGINE

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 battery issue. The dashboard showed a wrench in a car symbol as well as the battery symbol and a note that said "Stop safely now," and "full accessory power active." For the two and a half weeks following, I was not told what was wrong with the vehicle, nor was I provided a courtesy car. When I requested rental coverage, I was informed I would have to call "corporate" in order for them to cover the request, and when I did reach them, I was told that until they diagnosed the vehicle, they could not tell me whether it was my fault or theirs. After weeks of going back and forth, they agreed to cover a Ford rental (that I had to find on my own,) but have still not been given my vehicle as I have been informed that there are program wide software holds on the vehicle that prevent the technician from working on it. My lease ends in another month, and I have not been provided any information as to what my options are, or whether the vehicle will be fixed. I was also informed that I was not eligible for the Ford repurchase program as the vehicle is over the allotted 2 year/24K mile period, but I am extremely frustrated by the lack of care Ford has shown for my safety and ability to get around.
