2024 Ford Mustang Mach-E electrical system problems

“Our 2024 Ford Mustang Mach-E repeatedly displays "Pre-Collision Assist Not Available," meaning forward collision warning and automatic emergency braking assistance are unavailable. The Ford app recorded 26 occurrences from April 19, 2026 at 8:52 p.m. through October 11, 2026 at 1:51 p.m. No crash, fire, injury, or death occurred. The vehicle was purchased new on November 5, 2024 and is titled to my spouse; I am reporting as spouse, operator, and case coordinator. Performance Ford in West Covina has had three repair visits for this concern. Visit 1, July 29-August 10, 2026, in at 34,296 miles, repair order 240919: dealer found IPMA camera diagnostic codes B1385:68, B1385:82, and B1578:89, cleaned the camera area, and updated IPMA software under warranty. Visit 2, September 28-October 8, 2026, in at 37,701 miles, invoice 241715: the same IPMA codes appeared among many diagnostic codes, with service-required, brake-assist, and adaptive-cruise faults, and a "Stop Safely Now" fault occurred during the dealer's own test drive; the dealer replaced a frunk/hood latch and charged $841.01, but the warning returned on October 11, three days after pickup. Visit 3 opened…”

“On [XXX] while traveling south on [XXX] at highway speed (in heavy traffic), multiple dashboard messages started to flash, and the car came to a stop in the middle lane. Thankfully, the people behind me were paying attention and did not hit me. I could not get the car to start or put it in neutral. I called 911 and police were dispatched. They blocked two lanes of the highway to push the car to the side. I was able to override the emergency brake to get it into neutral. It was put on a flatbed and taken to Kings Ford for diagnostics. Kings Ford service said that there were pins that came disconnected that resulted in this. They said this was resolved. I have not had a recurrence since, but I can no longer trust the car. My concern is that there could be other 2024 Mustang Mach-E's with the same issue that could result in someone getting hurt. I have also opened a case with Ford EV support directly. I do have a video showing the dashboard messages that I was receiving. I was unable to attach this to the submission as it is a .MOV file.”

“My Ford Mustang Mach-E has repeatedly slowed down unexpectedly while using Adaptive Cruise Control and BlueCruise, even when there were no vehicles in front of me. The vehicle incorrectly displays a car ahead of me on the driver’s screen and begins slowing down as though it is following that car. However, the road ahead is completely clear. This has happened both on the highway while using BlueCruise and on local roads while using Adaptive Cruise Control. In both situations, the vehicle continued slowing down until I manually intervened. I believe it would have continued slowing to a complete stop if I had not taken control. This creates a serious safety concern because the vehicle can unexpectedly and significantly reduce its speed in moving traffic, putting me and other drivers at risk of a rear-end collision. There were no warning lights or error messages before or during these incidents. The only indication was the appearance of a vehicle on the driver’s display that was not actually there. The problem has not yet been inspected or confirmed by a Ford dealership. I am arranging a service appointment to have it investigated. The vehicle is available for…”

“While driving my 2024 Ford Mustang Mach-E GT in mild 49°F weather with a 95% battery state of charge, the vehicle suddenly displayed a 'Performance reduced to lower temperature' message on the dashboard. The vehicle entered a protective 'limp mode,' abruptly and unexpectedly reducing available motor power while actively driving in traffic. This sudden loss of propulsion created a hazardous driving condition. No secondary warning icons or wrench lights appeared. Contacted the Ford dealership, but they refused immediate diagnostic service due to technician availability. This code appeared on 9/15/26 dealership failed to return my call.”

“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…”

“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.”
