NHTSA Complaint #11682272 — 2024 FORD MUSTANG MACH E

I lease a 2024 Ford Mustang Mach-E. On [XXX] the vehicle suddenly displayed a High-Voltage Battery Fault, Powertrain Malfunction / Reduced Power warning. The dealer replaced the High-Voltage Junction Box (HVJB), however I am unsure whether the actual root cause was ever identified. This failure shows a major defect in the high-voltage electrical system. Separately, my vehicle is also subject to Recall 25S65 / NHTSA 25V404, where a discharged 12-volt battery can prevent the electronic door latches from opening, risking passenger entrapment. Ford has no remedy available and has only projected a future software update. My car is still at the dealership. These two issues are connected: the HV system (through the HVJB) powers the DC-DC converter that keeps the 12-volt battery charged. A failure on the HV side can starve the 12-volt system, which directly creates the entrapment risk described in the recall. I live in Florida, where extreme heat makes this risk especially dangerous for children, pets, and elderly passengers. What is my emergency plan...carry a hammer to break the windows on every trip? This is an unreasonable and unsafe expectation for consumers. Ford has not provided any fix or assurance of safety. I have specifically asked Ford whether my car is safe to drive — they have not provided any assurances, merely repeating that Ford has not issued a stop-driving order on the vehicle. This unresolved defect substantially impairs the use, value, and safety of my vehicle, and Ford has failed to provide an adequate repair.
