Impacts: Electric system software & fools/locks/linegae. The EV vehicle has suffered a catastrophic, complete failure of its central software architecture, specifically impacting the APIM module and RDS system. Ford's internal In-Vehicle Technology (IVT) records confirm this failure originated in December 2025 while vehicle was fully under its 3-year bumper-to-bumper warranty. Because vehicle's underlying diagnostic and software infrastructure is completely frozen in an unresolved "updating" loop, the vehicle's onboard diagnostic tools are entirely incapable of reading or reporting critical hardware and structural component failures. Initial service was May 26. This software failure has caused severe, active safety hazards. In July 2026, the driver-side door latch completely failed to secure. Because software is bricked, no diagnostic code or dashboard warning was generated. As a 100% disabled driver, I was forced to drive 35 minutes home from an oncology medical appointment physically holding the driver’s door shut at speed on public roads to prevent it from swinging open. Furthermore, vehicle's network connectivity has completely shut down while driving on 3 separate occasions. During door latch failure, I was trapped in a rural area with zero cellular service. Because onboard telematics and modem systems are frozen and failing to receive critical safety patches, vehicle's SOS Post-Crash Alert System and tracking telemetry are severely compromised. If an accident or ejection had occurred due to the door latch failure, emergency services would have had no automated tracking link. Ford has failed to repair this after multiple extended dealer stays and has admitted through their IVT department that vehicle is unfixable due to massive never before seen software failure via standard service and requires manufacturer buyback. Dealer files att show no vehicle updates since Feb 2026 tho IVT confirmed May 28 not updates since Dec 2025 from Ford known software glitch.

Summary: My 2025 Ford Mustang Mach-E GT has repeatedly experienced a complete and unexpected loss of propulsion while driving in active traffic. Each time, the vehicle displayed a red “Stop Safely Now” warning with additional critical alerts, followed by an immediate loss of forward motion with no prior indication. This left the vehicle stalled in traffic and created a significant safety hazard. Details of Each Incident: While driving under normal conditions or coming to a stop, the vehicle triggered the red “Stop Safely Now” alert with powertrain and brake warnings. Propulsion shut down instantly and the vehicle locked in Park, leaving it immobilized in traffic lane. I had to exit the vehicle and wait for it to complete a full power-down cycle before it would restart. After restarting, the vehicle operated with reduced functionality and limited range. Ford Roadside Assistance was contacted for every incident. Safety Concern: A sudden loss of forward motion in moving traffic poses a serious crash risk to me and to other drivers. The repeated nature of this failure suggests a defect in the propulsion system, sensors, electrical components or related modules. Current Status: The vehicle is now at the local Ford dealership for evaluation. I have also notified Ford Corporate Customer Care. The root cause has not yet been identified or resolved. Requested Action: I request that the federal safety agency document this complaint and consider further review due to the recurring safety-related failure and the potential risk to other owners.
