2023 FORD MUSTANG MACH E Power Train Problems

After stopping the vehicle to run an errand, the vehicle locked up. The steering wheel would not turn. The vehicle would not shift into any gear. The vehicle was inoperable and I found myself stranded 25 miles from home. The vehicle was towed to our local Ford dealership where it has been for the past two weeks. This failure could just as occurred on the road causing a dangerous situation.

Car constantly shuts down at electric vehicle charging stations and has even loss power will driving on highway and bought up powertrain fault

I have taken my car to the dealership is three different occasions and reported problems with the screens (they go black, even when driving), rear-view image missing, proximity sensor malfunctioning (beeps even when there are no objects or cars around) and the driving assistance system (constantly disengages and reports it, without intervention). Additionally, I've read that the recalls talks about a possible lock-out issue that could put my children well-being at risk and I'm aware of issues with the doors of the vehicle. Despite the multiple reports and trips to the repair department these problems are still present and this last time my car has been retained at the dealership for over a week without any update or ETA for fixing the problem and I'm being told my only option would be get a new car and start my financing all over

When the "High voltage junction box" malfunctions it can leave you stranded in an unsafe situation. Ford has been replacing them but the new ones also fail. A more robust HVJB should be demanded to avoid putting the public at risk.

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.

We were driving my Ford Mach E when the vehicle disengaged the accelerator pedal and accelerated forward in which we had no control of. Pressing the break would cause the vehicle to accelerate faster almost causing multiple accidents at a high rate of speed. Multiple sensor malfunction even after being “ fixed “

Vehicle failed to operate. Did not “turn on” and main battery power would not connect to transmission/motors leaving driver and passengers stranded.

Undocumented, programmed power loss at interstate speed. Power purposely and dangerously reduced at speed due, and is even displayed on the dash board with small "gray" bars within the "Power Gauge". The "Power Gauge" indicates power, regeneration and power reduction level. ***There is no reasoning in the Owners Manual explaining the power reduction.*** l only found this after I purchased the car; "When the system limits the available maximum power, the right side of the gauge shows gray lines representing the proportional reduction in available power."

All I was doing was charging the battery of the car at my house on a level two charger that was provided by Ford. I got a message on my Ford pass saying High voltage Battery warning. The car stopped charging at 59 percent of the battery capacity. The vehicle has only 2800 miles on it. Also got a power train malfunction/ reduced power warning as well and a service wrench when you turn on the car. This high voltage battery warning is a known issue on 2022 as I had it happen to me while driving it in a turn as I own one of those as well. But this is the 2023 that is not recalled. I have parked it outside of my garage as if the battery is getting hot enough to where it will stop charging this puts these vehicles all at the risk of something called thermal runaway. I do now know why this is not mentioned or even talked about with these types of batteries but basically, this happens when one cell goes into thermal runaway from being too hot and can melt the car. This is a huge safety concern. I have complained about it multiple times but have been ignored. I have parked my vehicle outside of my garage as I fear it may go into thermal away. I will take it to the dealer tomorrow. Please fix this NHSTA it's still not fixed. Happened to my 2022 Mustang Mach E with an extended-range battery now it's happening to my 2023 Mustang Mach e with an extended battery neither of which is part of the recall. If this is a known issue you must investigate it NHSTA and make Ford fix the issue not just wait until someone ends up dead this will not be acceptable and every time I have an issue like this and anyone who also has one should complain. Thermal runaway of a battery is a serious issue that can happen to this battery on the car. It is a real concern I have seen a battery much smaller on a helicopter go into thermal runaway it was not very pretty. Please Ford Fix this issue the high-voltage battery issue is already known.

After a few days in garage attempted to drive out where first upon engaging drive selection, releasing brake pedal, and slight throttle, a clunk and jerk launch occurred. With each subsequent wheel rotation there was a scraping sound synchronized with a torque dip in the propulsion. drove 1-2 blocks up street up to ~5 MPH and this symptom followed exact with speed. Stopped car, tried reverse a block, same thing, surging like propulsion with apparent torque dips in sync with speed. Repeated in drive, then reverse a few times, then parked back in garage to be towed into dealer. I put masking tape on steering wheel AND on Windshield saying not to drive over 2MPH to witness the symptoms. Upon receipt at dealer, was told symptom was then repeated, therefore car would be held for a while as it would need to be torn down and analyzed to find the cause. After 3 weeks, told not yet finding the cause, we discussed possibility of brakes where they agreed and was to pull them apart to inspect. Never did. Now 4 weeks later, still at dealer, telling me they cannot repeat the effect but that drove it around. I told speed may have wiped it away, this 2nd time it was towed in for this. I consider this a safety / drivability issue and want it noted, (And fixed of course).

My vehicle lost power when I was accelerating onto a highway. The car would not go over 35 mph all the way home. There was no warning light until after I attempted to accelerate and was not able to. Ford is saying it’s only 2022 models, but I have a 2023.

The contact owns a 2023 Ford Mustang Mach-E. The contact stated that the vehicle failed to start. The contact stated that after five minutes of attempting to start the vehicle, the vehicle started. The contact then stated that a message displayed on the instrument panel “High Voltage Battery warning and to Contact Roadside Assistance” and “Powertrain Malfunction - Reduced Power”. The contact stated that the vehicle decelerated and failed to accelerate while the accelerator pedal was depressed. Limited Power was displayed on the instrument panel. The vehicle was taken to the dealer where the cause of the failure could not be determined. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 1,317.

Mileage: 1,317

The car came to an abrupt stop and wouldn’t start up again. This happened three times. First time, I was at a charging station. Second time it happened in middle of the road while driving. It Put the safety of my family and me at danger. I had to call 911 to help manage busy traffic around me and towing service to take the car to dealership/service. The ford service center told me car was fixed - they had the car for 10 days before returning it to me. Two weeks and ~200 miles later the same thing happened yet again. My wife and child were stranded in middle of traffic. I am just thankful they were able to avoid collisions with other vehicles. The car has been back in the ship for another 24days and counting. Online forums indicate that my issue is not isolated. Ford has yet to comment or address my issue directly. Imagine the car coming to a full stop in the middle of a busy interstate highway!!

Vehicle suddenly lost power with a warning on the dashboard (service vehicle soon). The component ended up being a high voltage battery junction box (HVBJB) which was replaced by the dealer under warranty. This is a known issue reported on widely on forums such as macheforum.com

The HVBJB subassembly in ALL Ford Mach-e vehicles has known defects with 'under-designed' main contactors that are known to fail under normal charging and driving conditions as outlined in current open Ford recall notice for my vehicle 22s41. Unfortunately, the internal damage to contactors is not visible externally, and warning notices on display only after damage has occurred, and can result in sudden loss of propulsion power at highway speed, loss of power steering, and power brakes... and failure of other 12v systems due to failure to charge the 12v battery properly after contactors are damaged. Less catastrophic results can include failure to start; which can 'strand' driver's and passengers in remote areas, bad weather conditions, as well as cause loss of use for weeks due to delays in replacement parts and local Dealerships needing equipment and training to effect removal/replacement of faulty unit with a new HVBJB having re-designed 'beefier' components.​ ​ My complaint is that Ford's recall notice 22s41 is a software-only attempt to prevent future damage, and does not require removal of the part(s) which are KNOWN TO FAIL to be replaced with the re-designed components which are available, and have been used to repair failures under warranty. I have no way of inspecting the original equipment to evaluate current condition; and failure can result in sudden and unexpected loss of power, steering, and braking as well as potentially 'stranding me' in unsafe conditions unable to re-start my vehicle.​ Even though I have a MY 2023 Mach-E, it is known that the HVBJB is failing in '23s, and additional failures in earlier MYs that have had the HVBJB replaced with the newer part. ​ I would like to see NHTSA strengthen the Ford recall to include both improved software AND removal/replacement of the HVBJB sub-assembly with the new 'beefier' parts, even the latest revision of the part is still failing at an unacceptable rate.

2 days after ownership the vehicle shutdown and went into limp mode with a picture of a turtle and battery icon in middle of road with traffic, apple valley ford replaced the 12v battery and that solved the issue, today 3 days later same issue! Stuck in the road, ev battery charged to 90%

I took car a month ago and it stops between the road..saying STOP SAFELY NOW and than i am unable to move my car, it happened thrice, last time it stopped on the road and cop had to call roadside assistance so i contacted my dealer on 10 Aug about this issue, they diagnose the problem and re run test some test and recycled the system, now again today on 14 August, it got stopped in middle of traffic and the crash was about to happen, i was lucky that my life got saved or else it would be a major accident, so i went again to my dealer and explained everything now they are again gonna re run those test, but it's becoming a life threatening issue for me to drive this car, so please i need help for it.

All 4 occasions the service lights illuminated on the dash and power to the vehicle was reduced significantly. Took to the Dealer (David Wilson Villa Ford, Orange CA) on 8/9/23 - They indicated they could not replicate and there was no repair to make. Contacted Ford and they were unresponsive.

After backing out of the driveway, our Mach-e started accelerating without putting my foot on the accelerator. Car literally was just getting faster and faster without me doing anything. When I did press the accelerator after the stop sign to the entrance to our neighborhood, nothing happened and the car just rolled forward. Took my foot off the right pedal and it started accelerating again. Got out to the main road, had to pull over, and rode the brake back home. In short, the car accelerates without pressing the accelerator.
