2021 Ford Mustang Mach-E Recalls, Ratings & Complaints

Incident: August 8, 2026 · Filed: October 29, 2026

On August 8, 2026, my 2021 Ford Mustang Mach-E Premium experienced a serious electronic lockout. The vehicle was running, with the air conditioning and music on, when the doors locked and I was unable to regain entry. My keys, phone, purse, medication, and other essential belongings were inside the vehicle. I attempted multiple methods to regain access, including the driver’s door keypad, but I was unsuccessful. I remained locked out for approximately 7.5 hours and ultimately had to break the windshield to reach inside and unlock the vehicle. My understanding is that Ford had previously performed a recall remedy addressing a potential electronic door-lockout issue on this vehicle. I am concerned that the vehicle experienced a similar safety-related malfunction after that remedy. I do not yet know the precise technical cause and am requesting investigation. Following this incident, my vehicle experienced repeated 12-volt battery and no-start problems. When the vehicle was left at Kenny Ross Ford for diagnosis, I was later unable to get it to respond to the key or show lights or audible signals, and it did not appear to respond when connected to a charger. The dealership’s inspection subsequently recommended replacing the 12-volt battery and conducting a parasitic-drain test, but the report provided to me did not establish the cause of the original lockout. I am concerned that an electronic failure involving the door-latch system, 12-volt power supply, vehicle control modules, or recall-related software may have prevented safe access to the vehicle. I am requesting that NHTSA review this incident in light of Ford recall 25V404, manufacturer campaign 25S65, which addresses a potential lockout condition associated with low 12-volt battery voltage and electronic door latches retaining their locked state. I am not asserting that the recall has been proven to be the cause. I am requesting investigation into whether this incident reflects the same or a related safety defect

Incident: September 26, 2026 · Filed: October 11, 2026

2021 model mustang Mache got a new High Voltage Battery Warning on the dashboard and asked to stop the vehicle. My car is Premium trim standard range, but other trims and extended range battery models were recalled for this exact issue earlier, but the premium trim standard range car was not included in recalls. I have read online forums that many people who own standard range cars are seeing this warning suddenly now. Please work with Ford to include standard range cars from 2021 mustang Mache EV to recall for this repair, i think it is also called HVBJB error. I don't have the exact recall number issued for extended range cars earlier for this same error.

I was involved in a car accident on the XXX I was in the turn lane and a second vehicle hit my driver side, spun me around, and I ended up facing the opposite direction. What occurred next is my safety complaint. The vehicle continued to travel forward and, in fact, accelerated and I was unable to turn or stop in spite of hitting the brake. It caused me to hit a third vehicle and I stopped short of a gas line. There was a recall on this vehicle 22S29. The issue was a functional safety monitor software fault which potentially caused unintended acceleration, unintended deceleration, or unexpected movement I purchased the car in 2023. The recall was dated May of 2022 and was noted on the market valuation report / supplemental information. I was not aware of this recall and I do not believe the issue had been corrected prior to purchase in spite of being told that all recalls had been addressed prior to my purchase. Luckily, nobody was severely injured. I sustained chest wall contusion from the airbag, possibly rib fracture(s) and sternal fracture. My grandson who was [XXX] old was in the backseat and he was not injured luckily but was very traumatized. There were no warning signs. There was a police report but no ticket. The car was totaled so it is not in my possession at this time. The auto dealer that had performed several recall issues for me after my purchase did not have any record that this particular recall had been addressed. I have filed a complaint with Ford as well.

This is linked to tracking case 11768528. I wanted to provide the tsb: 23-2040. The fault causes the pre-collision assist to become disabled.

Incident: September 23, 2026 · Filed: October 2, 2026

The Pre-Collision Assist becomes suddenly unavailable when driving over uneven surfaces, including bumps and rumble strips. When the service center of my local ford dealer investigated this code, they discovered it is a software issue, and the only way to remedy the problem is to perform 5 software updates and an alignment: The updates are on: IPMA, PSCM, CCM, CMR, PDW. IPMA alignment. There are no other solutions to correct the issue to prevent the safety feature from failing. The impact of this failure is an increased chance of a collision due to sudden loss of front collision detection.

I own a 2021 Ford Mustang Mach-E Standard Range RWD. My vehicle has experienced a high-voltage powertrain malfunction involving the high-voltage battery system/HV Battery Junction Box (HVBJB). The vehicle is currently at a Ford dealership for diagnosis and repair. What concerns me is that the same high-voltage/powertrain warning appeared on my vehicle previously, before the vehicle reached 100,000 miles. The warning appeared in my FordPass history, then went away. The vehicle later developed the same type of warning again, and the problem has now resulted in a current high-voltage powertrain malfunction. My vehicle is not included in the existing HVBJB recall (23S56) based on its VIN/build configuration. I believe this may indicate that vehicles outside the current recall population can experience the same HVBJB/high-voltage failure. I contacted Ford about the issue and requested Goodwill Assistance. Ford denied the request. I am asking NHTSA to review whether the existing recall population adequately covers 2021 Mustang Mach-E vehicles experiencing this failure and whether vehicles outside the current recall population may have the same safety defect. The fact that the warning appeared before 100,000 miles is particularly important because it suggests the current failure may have been preceded by an earlier warning while the vehicle was still below the mileage associated with the battery warranty. I have FordPass history documenting the earlier warning and can provide additional documentation, including dealership diagnostic information, repair records, and photographs/screenshots if requested. I am concerned about the safety implications of a high-voltage battery/powertrain failure because loss of propulsion can occur while driving and may create a hazardous situation, particularly in traffic or at highway speeds.

My 2021 Mustang MachE experienced a failure of the relay which connects its high-voltage battery to the rest of the car. The car is an EV, and the result of this is that the drive-motor had no power, and the car would not move. I would like to ask, please, that all model years with this known-issue (HVBJB - high voltage battery junction box) be recalled.

Incident: August 19, 2025 · Filed: September 28, 2026

While accelerating on a highway on-ramp, the vehicle displayed Powertrain Malfunction/Reduced Power, a High-Voltage Battery Warning. Power was reduced while merging into traffic. The same warnings appeared at about 90,000 miles and cleared on their own. This is a Standard Range RWD Mach-E, which was excluded from the high-voltage battery junction box recall. The vehicle was towed to AutoNation Ford Katy and diagnosed with HVBJB failure. Loss of propulsion at highway speeds is a safety hazard. I am requesting that NHTSA investigate whether Standard Range vehicles should be included in the recall.

While driving my front passenger door opened. It has now done it several times while driving the vehicle. Also, I will lock my car and walk into the house and work and my door will open setting my alarm off.

Incident: June 15, 2026 · Filed: September 1, 2026

My 2021 Ford Mustang Mach-E (142,009 miles) intermittently fails to accept a charge at public DC fast-charging stations. My husband relies on these stations because our home electrical panel cannot support a home EV charger, and he uses this vehicle daily for his work in commercial real estate, often needing to charge it twice a day while traveling throughout Southern California. We first brought the vehicle to Tuttle-Click’s Capistrano Ford (San Juan Capistrano, CA) for this issue, and were charged $250 for a diagnosis and software-related repair (Invoice XXX, dated XXX). The technician’s notes state the vehicle would stop charging after about a minute at DC fast chargers, that the code P0EEE:27 was stored in the SOBDM module, and that the battery was manually charged to 99% and the code cleared. Ford refunded the $250 after the same problem recurred shortly after this repair. When we brought the vehicle back in a second time for the identical issue, the dealership informed us that Ford currently has no fix for this defect, and that only a Level 1 or Level 2 AC home charger can reliably charge the vehicle — which is not an option for us since we have no home charger installed. The dealership subsequently provided us with a copy of Ford’s own internal Special Service Message, SSM 55080, titled ‘Stop Charging When Using DC Fast Charger Level 3 With DTC P0EEE:27 And/Or P2E53:27 Stored In the SOBDM Module.’ This bulletin confirms Ford is aware this defect affects 2021–2023 Mustang Mach-E, 2022–2025 E-Transit, and 2022–2023 F-150 Lightning vehicles, that replacing the charge port hardware will not resolve it, and that a software fix was targeted for Q3 2026 — a deadline that has passed without a working fix reaching our vehicle. This defect leaves us with no reliable way to charge the vehicle away from home, directly impacting my husband’s ability to conduct his work.
