What 334 owners told NHTSA about the 2021 Ford Mustang Mach-e Bev Bev

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.

On October 15, 2023, with my EV battery charged at 69% and about 2 minutes after beginning my drive, I suddenly received a warning on the dashboard which stated "Stop Safely Now". Within 5 seconds, the vehicle would not accelerate and eventually came to a stop. The first episode of this occurred on Sunday, October 15. My car had to be towed to Gullo Ford in Conroe, TX, where I purchased the car in March 2022. The vehicle was serviced by Gullo Ford's service department on October 16, 2023. The repair invoice references replacing the electronic parking brake harness connector and reprogramming the battery charge control module per recall on October 16. 2023. I picked the vehicle up from Gullo Ford on the afternoon of October 16. The car worked normally until Monday, October 30, 2023 when the same thing happened. About 2 minutes after starting and driving the car, I received the warning to "Stop Safely Now". The vehicle would not accelerate. My battery was charged over 70% when this occurred. The first time this happened on October 15, 2023, I was able to coast the car into a parking lot, out of traffic. On Monday, October 30, my car did not have enough speed to allow me to coast out of the flow of traffic which left me stranded in my car during rush hour, blocking one lane and the entry to a turn lane. This was a very unsafe circumstance as my car would not accelerate again, leaving me without a way to move out of the flow of traffic. Again, my car had to be towed to Gullo Ford in Conroe, TX where it remains at this time. I do not feel safe driving a car which will stop accelerating with only a 5 second notice to "Stop Safely Now". I have no idea when this will happen leaving me stranded in the flow of traffic with no way to move.

Display gave warning - Service Vehicle soon and car did not start after being parked for about an hour. Outside temp was 65F. Car was driven about 400 miles that day including DCFC once. Had to be towed to dealership where it has sat for over 3 weeks with no repair and no information about what is wrong. I had someone familiar with the Ford system look up the codes who found that there was likely a problem with HVBJB that now is recalled. Not sure what to do anymore since dealership has car for 3 weeks now.

After using fast charger in Santa Rosa Ca, to 85% proceeded to freeway on ramp, getting on freeway on ramp, Message came up on screen "STOP SAFELY NOW" 2nd Message. "FULL ACCESSORY POWER ACTIVE. I pulled over to shoulder, unable to restart car. After getting started after 15-20 minutes again the same thing happen again 5 minutes later blocking lanes of traffic. Restarted after 25 minutes went to Ford dealership which was 1 mile away. Rented car and waited the next day till I called at 4;30 to see how car was and it was. The reason for incident from Ford technician was due to Erroneous network traffic caused the fault.??????? Needs to say I'm selling my MME 2021 I can't be stuck on freeway onramp or anywhere else, this is very unnerving to a [XXX] women and her 14 year old dog.

while driving, the range on the electric battery went from 150 miles to only 64 miles in less than a minute. when i went to the DC fast charger it gave error and could not charge even after i verified that the fast charger was operational because the next car was able to charge car with no issue. after a while when i charged the car, it started charging but drastically reduced the battery range. i have attached the picture. at 78% it only gave me 76 miles range. usually at 78% it gives me a 180 miles or higher. took my car to the dealer to run diagnostics and dealer don't seem to agree to any battery issue.

Car gave me the high voltage fault that many Mach e owners have reported. Car is in the dealership now and I don’t have the car. Why weren’t these recalled?

Ford delivered the car with only one key FOB which was corrected in later builds of the car. To fix this they had a program where you could go to your dealer to get the second key FOB for free. I set up an appointment to go to the dealer and was reassured that even though the date was after the expiration of the program I would still get the second key for free. When I went in I was told this was untrue and every Ford representative has told me that even though I was lied to they would not fix things for free as it should be with the program. Eventually I was told to contact nhtsa about this issue. I currently have to use my phone as a key which has become increasingly unreliable requiring my backup code often to be entered into the car even when my phone is on and has the Fordpass app open to act like a key. This has caused issues with when I shift out of drive or reverse that it places itself in park asking for the backup code to be entered again before I can continue driving.

I want to draw attention to a significant concern: U.S. auto safety regulators announced in August of this year that they are currently investigating whether Ford Motor's 2022 recall of nearly 49,000 Ford Mustang Mach-E electric vehicles comprehensively addressed the associated safety concerns. The basis for the 2022 recall was that the high voltage battery main contactors could overheat, particularly from DC fast-charging and repeated wide-open pedal events. This overheating presents a very real danger as it could result in an immediate loss of power, markedly increasing the risk of a vehicular accident. Furthermore, after the recall, Ford issued a technical service bulletin, directing the replacement of the High Voltage Battery Junction Box on the recalled vehicles. However, the National Highway Traffic Safety Administration (NHTSA) has since opened a recall query. This action was prompted by 12 consumer complaints related to Mach-E vehicles that had supposedly received the necessary recall fixes. It is worth noting that the High Voltage Battery Junction Box has been replaced on my Mach-E already, and I am still facing problems. This is my third encounter with this particular safety issue.

NHTSA ODI 11548102

We came out to our parked car and got a message that said Stop Safely Now. The vehicle would not shift into gear. The dealership had confirmed that the high voltage junction box has failed. We did not get the Service Vehicle Soon warning prior to the failure, despite having had the recall software update applied. The first sign of failure was a loss of motive power. This is a safety issue because loss of motive power while driving can result in loss of control of the vehicle. The loss of heating and cooling combined with the loss of motive power is also a significant safety risk if the failure occurs in a remote location experiencing extreme temperatures. The part has yet to be replaced, but I’m sure Ford will be retaining it for inspection.

Pre collision assist and front camera malfunctions randomly. Dealer did a software update and has not resolved the issue. This happens at least once every time the vehicle is driven. It is out of warranty and will not be covered. This is a problem that plagues a significant amount of vehicles, I follow a mach-e group on social media and it’s a prominent issue. If you’re using blue cruise. The vehicle stops self driving abruptly.

NHTSA ODI 11541581

The front camera system has failed. The cables need replacing, which was diagnosed by a Ford dealer. I have no collision assist, no cruise control, no lane keeping abilities, nothing that has to do with the camera in front. This is a known problem that Ford is not admitting to. All years of the Mach-E are having this issue, frequently. It has put myself and others on the road in danger by not being able to function as it should. Every time I turn the car on I get multiple warnings on the dash concerning these issues. This is not the only problem and safety issue I've had with this car in less than 9 months of owning it. Something must be done to hold Ford accountable.

It would appear that after the recall repair my car is experiencing problems that we’re supposed to be addressed with the recall. All systems are constantly malfunctioning.

The charging port on my Mach-E is failing. I am unable to change at the manufacture reported limit of 48 amps. If I try to charge my Mach-E at any rate higher than 32 amps, it will unexpectedly stop charging within 30 minutes, and only change the car 2% or 3% per charging session. Once I derate my EVSE to 32 amps, then my Mach-E can fully charge up to the 80% limit that I have set in the car within a single charge session. Several others have reported the same issue on the following forum post: [XXX] . It seems to be an issue with the temperature sensor in the charge port failing prematurely. I can confirm that the charging issue can occur outside of environmental factors like during a hot summer day. I usually charge during the late evening and at night, around 8:00 p.m. to 12:00 a.m., and the car always stops charging within 30 minutes. I have even charged successfully at a public L2 charger during the day when the charging cord handle was in direct sun light, and was hot to the touch. So the failure seems directly related to the charge rate. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The HVBJB subassembly in ALL Ford Mach-e vehicles has known defects with 'under-designed' main contacts that are known to fail under normal charging and driving conditions as outlined in current open Ford recall notice. Unfortunately, the internal damage to contactors is not visible externally, and warning notices on display only AFTER the 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 contacts 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.​ ​ 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.​

I am filing this complaint regarding the potential failure of the High Voltage Battery Junction Box. There have been many failures reported on the forums some experiencing multiple failures. Ford provided a software update that supposedly predicts an impending failure reducing available propulsion power. I do not feel comfortable driving a vehicle with a ticking time bomb. Losing propulsion power while driving at highway speeds could result in a serious safety senerio. I would like to see Ford provide a real fix.

NHTSA ODI 11540005

Ford has installed a sub par HVBJB in my car which was manufactured in 12/01. In lieu of replacing the poorly designed unit they have added software that does not guarantee that the car will not brick. Numerous car have failed and I am afraid of having my wife drive the car at night for fear of it breaking down. This is a ticking time bomb.

Began to receive error messages stating "Front Camera Fault" and "Forward Collision Detection Fault". For a while it fixed on its own, then the messages started to become more and more frequent until now the error messages come up every time we turn on the car. With the malfunction that is happening with front camera and collision detection, it prevents cruise control from being used (which is adaptive) and forward collision warnings are not working/inactive. The lack of both of these systems presents a safety issue. The car has been taken to the local Ford dealership which has determined what needs to be replaced (the front camera and cables connecting the camera). However the parts must come from the Ford manufacturer and there is current no ETA that the dealership is being given for the parts to be delivered. When searching online for this issue, there are other owners that have experienced this and there is currently a TSB for this issue (TSB 23-2155).
