2024 Ford Mustang Mach E: doors won't lock, open or latch

Filed Aug 21, 2025 · Electrical, Fuel system · FL

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 / the federal safety agency 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.

I am reporting a serious safety defect involving the electronic front door latches on my 2024 Ford Mustang Mach E. During a 12V battery discharge, the electric latches can fail, preventing the doors from opening in the outside. This means the driver or passengers could become trapped in the vehicle, or the driver can be locked out in an emergency, even if both key fob and key are present. This defect poses a critical safety risk in situations requiring a rapid exit - such as accident or extreme heat and increases the risk of injury or death. As an active duty service member, I work in a secure federal government facility and have to leave my phone in my vehicle during working hours. This heightens the danger, because if the latch fails, I would have no secondary means to gain entry or exit, potentially delaying emergency responses. Ford has acknowledged the defect in the recall (25S65/25V404) in early June. They said to expect an update by the end of Q3, which is nearing and I haven’t heard anything yet. I believe this defect warrants urgent attention, and consideration of a manufacturer buyback due to severe safety implications.

I lease a brand-new 2024 Ford Mustang Mach-E with approximately 5,000 miles. The vehicle is subject to the federal safety agency Campaign Number 25V404 (Ford Recall 25S65) for defective exterior electronic door latches that may fail to open if the 12-volt battery discharges. Ford has confirmed there is no repair available and no timeline for a fix. This defect has been acknowledged by my Ford dealer and Ford corporate. While Ford states that the interior manual handles still function, this ignores a serious real-world safety hazard. I frequently transport dogs and other passengers who cannot operate the manual handles. If I step outside the vehicle — even briefly — and the exterior handles fail, these occupants could be trapped inside. In an emergency such as extreme heat, cold, or fire, this could result in injury or death, and rescue would require breaking the glass, creating additional risk of harm. Ford’s own recall language acknowledges this is a “safety defect,” yet the current stance is that the vehicle is “safe to drive.” This does not address the entrapment risk for vulnerable occupants. The defect has not yet resulted in entrapment or injury, but it is an active and unresolved hazard that could occur without warning. This complaint is being filed to document the risk before harm occurs and to ensure a timely, safe remedy is provided.

The contact owns a 2024 Ford Mustang Mach-E. The contact received notification of the federal safety agency Campaign Number: 25V404000 (Electrical System, Latches/Locks/Linkages); however, the part to do the recall repair was not yet available. The contact stated that after the vehicle was parked with the engine turned off, the front driver’s side door failed to open as intended. After several attempts with the key fob and the door latch, the doors failed to open. A family member opened the door. The local dealer was contacted. The vehicle was not repaired. The contact was informed that the door needed to fail three times to be repaired. The contact stated that on a separate occasion, while driving at an undisclosed speed, there was an abnormal sound coming from the vehicle. The vehicle was not diagnosed or repaired after the most recent failure. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The failure mileage was approximately 9,500.

[XXX] @ [XXX] The door locks are not opening from the outside. The battery will not charge. I cannot get my items out. I have a [XXX] work & personal electronics, along with personal items for myself & my family, inside that I cannot access. It's early Sunday morning, I am over 3 hours away from home, in Corpus Christi, with my brother & [XXX] nephew, along with both of my Dogs. The ford dealerships in this city will not be open until Monday. The plan was to stay for a night & drive back home, as both myself & brother have to work on Monday. I am a therapist (Psychotherapist) with critical clients, & this is problematic. This is NOT the 1st or 2ND time I had an issue like this. This is actually the 3RD time, but the last time I dealt with this, the dealership had no recollection or documentation of a bad battery or battery issues; however, that IS what I was told the first time, but when I picked it up, I was told they just FIXED something, with the battery. The 2nd time, the doors locked up, the battery would not charge & I had it towed to the same dealership, that it was purchased from, from my home of Giddings, TX to College Station, TX, & I was told, I needed a whole new Battery replacement. The car was purchased brand new with approximately 11 miles in October/November of 2024, & it currently has between 7000-8000 (I do not remember the total amount, but it has over 7,000, but less than 8,000). Fast forward to roadside giving me a hard time for having to bring a device to charge the battery to open it, leaving, & cutting my wrist, while grabbing things out of the vehicle, between the seat & center console, as my hand got stuck, & I forgot the seat could not move without any electric charge (there is a JAGGED edge in between that it's dangerous for ANYONE, & it's hidden by a cloth flap). I also had to pay for a rental vehicle despite having this service, when the dealership opened, for 2 days). INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
