Battery & Propulsion Reliability
Battery Electric (BEV)
Battery & propulsion complaint analysis for the 2021-2025 Ford Mustang Mach-E
That's roughly 5.7x the typical rate for BEVs in this dataset (median 5.5 per year). This generation has materially more battery & propulsion complaints than its peers, even after accounting for sales volume.
What kind of battery complaint?
Among the 227 battery-related complaints, here's the type mix. These percentages describe what the complaints are about — not how reliable the vehicle is overall.
Propulsion battery defects, capacity loss, BMS faults, replacement claims.
Low-voltage battery deaths, common on EVs and hybrids that use a 12V for accessories.
Loss of power, drive unit, inverter, traction motor, DC-DC converter.
Charge port, cable, mobile connector, or session failures.
Regen brake feel, one-pedal driving, B-mode complaints.
Battery fires, smoke, thermal runaway. Includes any complaint with fire reported.
Sample complaint excerpts
High-Voltage Battery
- [2021] 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 a
- [2021] 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 co
- [2021] The contact owns a 2021 Ford Mustang Mach E. The contact received notification of NHTSA Campaign Number: 25V404000 (Electrical System, Latches/Locks/Linkages); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that his wife parked and turned off the vehicle; however,

- [2021] On Saturday, [XXX], while driving under normal conditions, the vehicle experienced a sudden and complete loss of propulsion without warning. There was no reduced-power mode, no dashboard alert, and no mobile app notification prior to shutdown. The vehicle was subsequently inspected by a Ford dealership. The technician identified an intermittent software-related condition consistent with Ford TSB

Electric Propulsion
- [2021] 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

Charging System
- [2021] 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 wor
- [2021] The contact owns a 2021 Ford Mustang Mach-E. The contact stated that the vehicle failed to charge as designed. The vehicle was taken to the dealer, who informed the contact that they were awaiting the charging port and had ordered an unknown part; however, the part was on backorder. The contact stated that the vehicle was undrivable and remained at the dealer. The dealer notified the manufacturer
- [2021] 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 withi
Regenerative Braking
- [2021] It accelerated unexpectedly with no input while decelerating in one pedal drive mode. Cruise control was not in use at all during the drive.
- [2021] Mach e standard edition shows multiple signs of a failing High Voltage Battery Junction Box (HVBJB). The vehicle was bought certified pre owned with only 12k miles on the vehicle. At 16k miles (2 months of ownership) the vehicle showed a high voltage battery warning and power train malfunction warning. Three warning lights were displayed on the dash which were: a yellow turtle, wrench, and car
- [2021] There is a permanent fault on the front camera of the vehicle, making it unavailable. This has permanently disabled the vehicle's pre-collision safety feature. The adaptive/normal cruise control is also unavailable because of this. Prior to the permanent issue, the fault would occur randomly and without warning, creating an extremely hazardous condition, especially while utilizing the vehicle's "o
Thermal Events
- [2021] My vehicle was built with under-specked high voltage battery joint assembly bracket. The failure of this connection has caused many incidents whereby the car cannot start, or suddenly stops while driving. The part is either not to original specification or was not designed correctly. In either case, providing a SW fix to simply limit the voltage does not actually prevent or correct the problem.
- [2021] The contact owns a 2021 Ford Mustang Mach-E. The contact stated while charging the vehicle, he smelled smoke coming from the garage. The contact checked and noticed that the odor was coming from the wire that connected the charger to the wall outlet. The charger was the original equipment; Ford wall box Model: ML9Z-10C83-A. The dealer was contacted and a complaint was filed. The dealer stated they
- [2022] I am going to try to explain this as best as I can. Ford has faulty charging cables that they know about and have not recalled voluntarily. This I have an issue with because it is causing the battery on my car to overheat and put it at a potential risk of catastrophic thermal runaway incident. I have had two charging cables go bad on my car. I just got my car back today and I noticed the new cable
Source: classified from NHTSA complaint and recall data. "Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. Rates are absolute counts, not normalized per-VIN — high-volume models naturally produce more raw complaints than low-volume ones. Self-reported death and injury counts are capped per complaint to limit form abuse.
