Subject: Formal Safety Complaint – Sudden Unintended Acceleration, Suspected System Malfunction, and Collision Following Recall Repair I am writing to formally report a serious safety incident involving our 2024 Ford Mustang Mach-E, which experienced sudden unintended acceleration and crashed into a commercial building just a few days after undergoing a recall repair at Future Ford of Sacramento. Our vehicle has been subject to three recalls within the past 12 months, raising significant concerns about its reliability and overall safety. On October 10, 2026, we took our vehicle to Future Ford of Sacramento for recall-related repairs, including Recall 26B07, concerning unintended acceleration associated with the Adaptive Cruise Control system. According to the service documentation, the recall repair was completed. However, approximately five days after this repair, our vehicle suddenly accelerated on its own, without the driver’s intention or command. The vehicle became uncontrollable, and despite our attempts to regain control, it continued accelerating and ultimately crashed into a commercial building. Even more concerning, the vehicle’s automatic emergency braking system did not activate, no collision warning was issued, and no apparent safety intervention occurred to prevent or reduce the impact. We strongly believe this incident may have resulted from a serious vehicle system malfunction rather than driver error, particularly considering the vehicle’s recall history and the recent repair involving unintended acceleration. This incident placed our lives in immediate danger and could have resulted in catastrophic injuries or fatalities. We are requesting a comprehensive, independent technical investigation into the vehicle’s electronic control systems, acceleration system, Adaptive Cruise Control, automatic emergency braking, collision avoidance features, and all relevant software and safety systems. We want to emphasize that this was not an ordinary accident.

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 inspection. I am concerned that the vehicle’s driver-assistance system is incorrectly detecting vehicles and reducing speed without a valid reason. I am reporting this because the behavior has occurred multiple times under different driving conditions and presents a potential safety hazard. I’ve had a number of electrical issues with this car since I purchased it less than a year ago, and I no longer trust it.

There is an issue with the Mach E where while in a parking lot at low speeds the user may accidentally press the cruise control setting which will initiate the car jolting up to 15 mph (minimum speed for adaptive cruise control system) instantly. This happens when you are going 5 mph or less in a parking lot. Although this is more of a design issue where some users may not deal with this issue, it should be noted that forums have been posted about this same exact issue and it can cause a danger in terms of hitting pedestrians or other vehicles in parking lots or other slow moving traffic. There have been several instances where this has happened to me.

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.

Everyday I drive the vehicle There are 2 error messages 1. Front Camera fault, service required 2. Pre-collision Assist not available I have 32 Pre-collision warning messages in the last month, one for every day I drive. I had to drive 4 hours with no cruise control causing my leg to cramp at the 2 hour mark. There needs to be a recall for this issue. Many many other owners of the Mach-e have mentioned the same.

There is an issue with Cruise Control while moving out of a parking space. I am concerned for my wife who knows nothing about technology. If she were to MISTAKENLY press the Cruise Control button while parked and a car is in front of her, the car's Cruise Control will ACTIVATE AND LUNG FORWARD at a speed of 15MPH. This can be frightening and in a panic a person can crash. This has happened to me on SEVERAL occasions but I am able to handle the situation. If it happens to my WIFE, there surely will be a HUGE problem. I can reproduce the problem very easily. If you are parked behind a car Cruise Control can be activated. If you are STOPPED and there are no cars in front of you, you CANNOT activate Cruise Control. Therefore, when you need Adaptive Cruise Control (for traffic jams) a double click of the button seems feasible. Single click when you are over 30mph. This should be an easy software update.

Was driving when the driver instrument display went blank and is no longer functioning. This display shows speed of vehicle and other status information, such as battery level, range and cruise control status. There has been a software update remotely installed today, which may be a coincidence.
