What 42 owners told NHTSA about the 2024 Ford Mustang Mach-e Bev Bev

The exact failed component is unknown to me at this time, but the issue appears related to the vehicle’s electrical system. Prior to the incident, I received a charging error notification while the vehicle was plugged in. I unplugged the charger from the wall outlet, waited briefly, and plugged it back in. Later that same day, the vehicle entered a no-start condition and would not start despite repeated attempts over approximately two hours. The vehicle is available for inspection upon request. The vehicle left me stranded at night for approximately two hours without warning. Because the vehicle would not start, I was unable to reliably move or operate the vehicle. Depending on location, weather conditions, surrounding traffic, and other circumstances or emergency situations, this type of failure could place occupants and other drivers at risk. Additionally, I previously reported a separate safety-related incident involving this same vehicle in February 2026 in which the vehicle suddenly and unexpectedly accelerated in my daughter’s daycare parking lot. This has not been reproduced. The vehicle unexpectedly started and operated again at approximately the same time the tow truck arrived, after remaining inoperable for roughly two hours. Because the issue resolved itself without repair, it’s not clear what the root cause is. The vehicle has not yet been inspected. The vehicle has remained garaged following the incident pending further evaluation and communication with Ford. There were some warnings. Prior to operating the vehicle that evening, I received a charging error notification while the vehicle was plugged in. After unplugging and reconnecting the charger, the vehicle later experienced the no-start condition. During the incident, the vehicle provided no clear indication through the vehicle interface or mobile app explaining why it would not start, only “Stop safely now.”

The vehicle experiences a drivability issue where it stalls or loses power and is not safe to operate. The vehicle is currently undrivable and has been at the dealership for nearly one month without a completed diagnosis or repair. The dealership has indicated a possible powertrain or transmission-related issue, but no confirmed repair has been completed. Additionally, there is an active safety recall associated with the vehicle that has not been repaired multiple notifications. This situation poses a safety risk and remains unresolved despite repeated follow-ups.

While picking up my daughter from school this week, I entered a school parking lot and began a low-speed right turn to pull into a parking space. During this maneuver, the car unexpectedly and abruptly accelerated forward. I reacted immediately and applied the brakes, but the car traveled approximately two car lengths beyond the intended parking spot. I came to a stop across two parking spaces. This occurred in an active school pickup area with parents and children nearby. There were no cars or pedestrians directly in front of me at that moment. I still fear what the outcome might have been if anyone had been present. Immediately after stopping, I observed that the adaptive cruise control speed indicator on the instrument cluster was set to 15 and was crossed out, indicating it had recently been active and disengaged. However, I did not engage adaptive cruise control during that trip. Based on the car’s behavior and the display state, my best assessment is that adaptive cruise control was unintentionally engaged during the parking maneuver causing the car to attempt to accelerate toward a previously set cruise speed despite being in a low-speed, turning scenario. Again, I did not use ACC on this trip. A sudden acceleration in a school parking lot presents an extreme hazard. The only reason this incident did not result in injury or death was immediate braking and luck. There were no warning lamps or messages prior to the incident. The car has not yet been inspected by a dealer or manufacturer. I am aware of multiple publicly shared videos from other Mach-E owners documenting similar incidents, some resulting in crashes. This appears to be a systemic adaptive cruise control design or software issue that warrants immediate investigation and correction to avoid serious injury or death.

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.

What component or system failed or malfunctioned, and is it available for inspection upon request? The high-voltage battery system and powertrain system both failed. The vehicle went into limp mode, showing alerts for “Powertrain Malfunction / Reduced Power” and a “High-Voltage Battery Warning.” The vehicle is available for inspection if requested. How was your safety or the safety of others put at risk? The incident occurred while driving on the freeway at 75–77 mph, which significantly increased the risk of a crash. The sudden loss of power in heavy traffic was dangerous and could have led to a collision. Has the problem been reproduced or confirmed by a dealer or independent service center? Not yet. The issue has been documented through the Ford app and in-vehicle warning messages, and I am in the process of waiting for a diagnostic to be completed by the dealer. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Waiting for dealer to look at it. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes, immediately before and during the failure, the vehicle and the Ford app displayed messages indicating a powertrain malfunction/reduced power, along with a high-voltage battery warning alert. Additional description: While driving on the freeway at approximately 75–77 mph, the vehicle suddenly entered limp mode with a dramatic reduction in speed and power. Warning lights for a powertrain malfunction and high-voltage battery appeared. This created an unsafe situation in high-speed traffic. The vehicle had approximately 1,459 miles at the time of the incident. This also happened on my 2022 ford mustang Mach E 8 other times.

While driving the vehicle electrical console started flashing then lost power and stopped dead in the road. The battery was reading between 70% to 80% prior with a range of over 250 miles still available. Due to complete lack of any power the car could not be moved or placed into neutral for towing. It caused a traffic situation blocking 2 lanes of traffic for approximately 4 hours waiting for roadside assistance for jump start and towing. EV's cannot be towed like a regular car and not having access to the electronics made the car like a brick. Eventually I was able to attain assistance with a jump start that was able to provide enough power to drive onto the back of a tow truck and to the Ford dealership. Roadside assistance noted the 12-volt battery at the front of the vehicle was bulging and potentially overheated creating a potential explosion hazard and lack of electrical support to the main vehicle.
