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.

This issue also affects: Ford Explorer, Ford Fusion, Ford Transit

Common Symptoms

  • Vehicle completely unresponsive to key fob
  • Cannot unlock doors or open frunk
  • Phone-as-key does not work
  • Dashboard shows no power at all
  • FordPass app shows vehicle offline
  • 12V battery voltage below 10V

How to Fix

Install the latest OTA software update, which includes improved 12V battery management. If the 12V battery has died, use the manual door release (under the front left fender), then connect a 12V charger or jump pack to the terminals under the hood (positive terminal under a cap near the frunk). A battery tender connected when parked for extended periods prevents drain. If the issue recurs frequently, have the dealer test the DC-DC converter and replace the 12V battery ($150-250).

Typical repair cost:$0 - $500

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. The affected modules were produced with a faulted non-volatile memory component that prevents the module from rebooting; once it fails, the turn signals, daytime running lights, low beams and high beams all stop illuminating. 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.

Common Symptoms

  • Low beam and high beam headlights fail to illuminate
  • Turn signals inoperative
  • Daytime running lights do not come on
  • Multiple exterior lighting functions lost simultaneously
  • Exterior lighting fault message in the cluster

How to Fix

A free recall remedy exists. Under NHTSA campaign 25V885, Ford will release an over-the-air software update, or dealers will update the LDCMB software, at no charge. Interim owner notification letters explaining the safety risk were scheduled to be mailed January 30, 2026, with a second letter once the remedy became available in approximately April 2026. Because the fix is a software update to a module with a memory fault, owners should confirm the update actually took; a module that has already failed hard and will not reboot may require module replacement instead, which remains covered under the campaign.

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.

This issue also affects: Ford F-150, Lincoln Nautilus, Ford Mustang

Common Symptoms

  • 15.5-inch screen goes black while driving
  • Screen freezes and does not respond to touch
  • System reboots spontaneously showing Ford logo
  • Climate controls unavailable during reboot
  • Backup camera blank when screen is rebooting
  • Apple CarPlay/Android Auto disconnects

How to Fix

Install all available OTA software updates — Ford has released numerous stability fixes. Perform a soft reset by pressing and holding the power button on the center screen for 10 seconds. For a full system reset, disconnect the 12V battery for 2 minutes. If freezing persists after updates, the APIM (Accessory Protocol Interface Module) may need replacement under warranty. Avoid running many apps simultaneously to reduce memory pressure.

Typical repair cost:$0 - $1,200

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. Unlike some competitors, the Mach-E lacks an active battery preconditioning system that warms the battery before arriving at a charger (added via OTA for newer software versions). Cold weather fast charging sessions can take 2-3 times longer than expected.

Common Symptoms

  • DC fast charging at 10-20 kW instead of 100+ kW
  • Charging session taking 2-3 times longer than expected
  • Battery temperature indicator showing cold
  • Estimated charge time much longer than usual
  • Charging speed does not increase even after extended session

How to Fix

Use the trip planner in the navigation system — on newer software versions, it activates battery preconditioning when routing to a DC fast charger. Drive at highway speeds for at least 20-30 minutes before arriving at a charger to warm the battery. If possible, charge when the vehicle has been recently driven rather than after sitting overnight in cold weather. Setting the cabin pre-conditioning while plugged in at home also warms the battery. Install the latest OTA update for improved preconditioning.

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 never mechanically locked even though the cluster shows P. 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.

Common Symptoms

  • Vehicle rolls away after being shifted into Park
  • Cluster displays P but the vehicle is not mechanically held
  • Vehicle creeps or moves on a grade with the shifter in Park
  • No audible or tactile park engagement when selecting P

How to Fix

A free remedy exists. Under NHTSA campaign 25V863 (Ford reference 25C69), the park module software is updated over the air or by a dealer at no charge, with the remedy anticipated February 2026 - the software change alters how the module drives the pawl so it fully seats. For 2025 vehicles under 25V394, dealers replace the transmission park rod assembly. Until the remedy is applied, always set the electronic parking brake and, where possible, curb the wheels - the parking brake acts on the rear calipers and is independent of the failed park pawl.

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.

This issue also affects: Ford Edge, Ford Bronco Sport

Common Symptoms

  • Crack appearing from windshield edge
  • No visible impact point
  • Crack grows rapidly across windshield
  • ADAS warning lights after crack develops
  • Multiple windshield replacements needed

How to Fix

Replace the windshield. Due to the ADAS camera system, professional installation with camera recalibration is required — total cost $800-1,500 at a dealer, $500-1,000 through a specialty glass company. Safelite and similar mobile glass services can handle Mach-E windshields but must perform ADAS recalibration. File an NHTSA complaint if no impact caused the crack. Some owners have gotten Ford goodwill coverage for stress cracks on vehicles under basic warranty.

Typical repair cost:$500 - $1,500
