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 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.
