2025 Ford Mustang Mach-E Problems: 7 Known Issues

On the 2021-2025 Ford Mustang Mach-E, the Ford Mustang Mach-E has a critical design issue where a depleted 12V auxiliary battery can cause the electronic door latches to become inoperable, potentially trapping occupants inside the vehicle. The doors use electronic latches, and if the 12V battery discharges below 8.4V at key-off the e-latches keep their locked state, so a front door opened with the mechanical inside release handle and then shut stays locked, locking the driver out and potentially trapping an occupant who cannot use the inside release handles, such as a child in the rear seat. Ford recalled 197,432 vehicles (NHTSA 25V404000) to address this with a software update. The 12V battery in the Mach-E is under heavy load from constant electronic systems and can drain faster than in conventional vehicles, especially in cold weather or if the vehicle sits unused for extended periods.

On the 2021-2025 Ford Mustang Mach-E, the Mustang Mach-E 12V auxiliary battery drains prematurely, leaving the vehicle completely inoperable. Unlike ICE vehicles, the Mach-E cannot be jump-started in the traditional sense when the 12V dies — the vehicle cannot even unlock its doors or engage the HV system. The 12V battery charges from the main HV battery via a DC-DC converter, but software bugs can prevent proper charging when the vehicle is parked. OTA updates have addressed some scenarios, but the issue recurs for many owners.

On the 2025-2026 Ford Mustang Mach-E, ford recalled approximately 45,047 Mustang Mach-E vehicles because the Light Driver Control Module B (LDCMB) may fail. A faulted non-volatile memory component within the module can prevent it from rebooting; once it fails, that headlamp assembly's high beam, low beam, position lamp, daytime running lamp and turn signal all stop working. This is a hard electronic failure of the module rather than a bulb or LED problem, which is why an entire cluster of unrelated exterior lamp functions goes dark at once - a distinctive symptom pattern worth recognizing. Losing exterior lighting reduces both the driver's forward visibility at night and the vehicle's conspicuity to other traffic. The vehicles fail to comply with Federal Motor Vehicle Safety Standard 108, 'Lamps, Reflective Devices, and Associated Equipment.' Ford reported no accidents or injuries related to the defect at the time of filing.

On the 2021-2025 Ford Mustang Mach-E, the Mach-E SYNC 4A infotainment system with the 15.5-inch touchscreen experiences freezing, black screens, and spontaneous reboots while driving. Since the touchscreen controls nearly all vehicle functions (climate, charging, drive modes), a frozen or rebooting screen can leave the driver unable to adjust settings or use navigation. The system may take 30-90 seconds to reboot, during which the backup camera and climate controls are unavailable. Ford has released multiple OTA updates to address stability.

On the 2021-2025 Ford Mustang Mach-E, the Mach-E DC fast charging (DCFC) speed drops dramatically in cold weather, sometimes charging at 10-20 kW instead of the rated 115-150 kW peak. The battery management system limits charging current when the battery is cold to protect cell health. Early software lacked battery preconditioning before DC fast charging; Ford later added En-Route Preconditioning via OTA, which warms the battery only when navigating to a DC fast charger. Cold weather fast charging sessions can take 2-3 times longer than expected.

On the 2024-2026 Ford Mustang Mach-E, ford recalled approximately 88,064 Mustang Mach-E vehicles because the integrated park module may fail to lock into the park position when the driver selects Park. The park pawl can bind against an adjacent slider and fail to return to the fully engaged position, so the driveline is not mechanically locked; when this happens the cluster does not illuminate P and shows a wrench light and a shift system fault message. Ford traced the condition to variations in the manufacturing process plus possible material issues that create extra friction at the pawl/slider interface. The vehicles do not comply with Federal Motor Vehicle Safety Standard 114, 'Theft Protection and Rollaway Prevention.' A loss of park function allows the vehicle to roll away, increasing crash risk. This campaign was filed alongside related Ford park-system recalls covering the F-150 Lightning and Maverick - roughly 273,000 vehicles in total - but the Mach-E is named in its own right in 25V863. A separate, narrower 2025-model-year campaign (25V394) covers a park rod that may fail to engage the park position and is remedied by replacing the transmission park rod assembly rather than by software.

On the 2021-2025 Ford Mustang Mach-E, the Mustang Mach-E windshield is prone to developing stress cracks that originate from the edges without any rock chip or impact. The large, steeply raked windshield is under significant structural stress, and temperature changes can trigger crack propagation. The windshield also houses sensors for Lane Centering and adaptive cruise control, making replacement expensive due to required ADAS camera recalibration. Some owners have replaced the windshield 2-3 times.
