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.

I was involved in a car accident on the XXX I was in the turn lane and a second vehicle hit my driver side, spun me around, and I ended up facing the opposite direction. What occurred next is my safety complaint. The vehicle continued to travel forward and, in fact, accelerated and I was unable to turn or stop in spite of hitting the brake. It caused me to hit a third vehicle and I stopped short of a gas line. There was a recall on this vehicle 22S29. The issue was a functional safety monitor software fault which potentially caused unintended acceleration, unintended deceleration, or unexpected movement I purchased the car in 2023. The recall was dated May of 2022 and was noted on the market valuation report / supplemental information. I was not aware of this recall and I do not believe the issue had been corrected prior to purchase in spite of being told that all recalls had been addressed prior to my purchase. Luckily, nobody was severely injured. I sustained chest wall contusion from the airbag, possibly rib fracture(s) and sternal fracture. My grandson who was [XXX] old was in the backseat and he was not injured luckily but was very traumatized. There were no warning signs. There was a police report but no ticket. The car was totaled so it is not in my possession at this time. The auto dealer that had performed several recall issues for me after my purchase did not have any record that this particular recall had been addressed. I have filed a complaint with Ford as well.

I had put the vehicle into One Pedal Drive mode for the first time on the morning of Aug 29th. Vehicle operated as it should for first few places I drove to and stopped, but then I approached a red light, removed foot slowly from accelerator and vehicle came to a full stop as it should. Approximately 2-5 seconds later, without warning or even the collision avoidance system activating, my vehicle suddenly accelerated into the rear of the stopped truck in front of me. Fortunately no serious injuries but someone could have been killed. My foot was NOT on the accelerator at the time - it was hovering over it while waiting for the light to change to green. My vehicle was taken to Ford for evaluation, but they claim it has to be repaired before they can diagnose/confirm the issue. I am the original owner with no previous accidents or incidents.

Multiple intermittent electrical/software malfunctions in my Ford Mustang Mach-E, one of which poses an acute safety risk. STEERING WHEEL BUTTON / UNCOMMANDED ACCELERATION: A button on the steering wheel, when pressed, causes the vehicle to suddenly accelerate to a high speed with no corresponding throttle input from me, and speed cannot be immediately brought back under control. This creates a serious risk of collision to myself, passengers, and other road users. DOOR LATCH: A door does not open fully ("bounce open") as designed. This matches Ford recall 25V404, covering doors that may fail to open, potentially trapping an occupant during an emergency exit. ALARM SYSTEM: Alarm is either overly sensitive (false triggers) or fails to trigger when it should — an inconsistent fault suggesting an underlying electrical issue. DISPLAY SCREEN: Center/instrument screen intermittently goes black while driving, temporarily removing visibility of speed, warnings, and camera views. REAR SOUND BAR: Rear-seat speaker intermittently stops working. Not itself a safety risk, but suggests a broader wiring/electrical fault affecting several systems at once. Component available for inspection: Yes, upon request. Reproduced/confirmed by dealer or independent shop: UNKNOWN. I have called the dealer twice and been unable to reach anyone to schedule diagnostic service. Inspected by manufacturer, police, or insurance: UNKNOWN. No inspection has occurred yet. Warning lamps/messages before failures: UNKNOWN. No consistent warning appeared beforehand; symptoms occur intermittently without advance alert.

I was backing out of a parking spot in a strip mall, when I changed the gear to Drive, and moved forward by a foot. I felt a bump, as I appeared to have hit some obstruction on the left underside of the vehicle (likely a low curb/island). After that, I lost control of the vehicle - the car accelerated very hard, and I tried to stop the car, but it was not responding to my brake input. I crashed into a stationary vehicle, which deflected my car to a storefront wall. The total distance travelled from when the sudden acceleration started to the crash against the wall, was probably 20 - 30 feet (and not in a straight line). But the impact was severe enough to have deployed the air bags and the car is considered totalled. Besides the sudden acceleration which did not happen on my input, and the inability of the car to stop based on my brake input, neither did the Forward Collision Warning go off, nor did the Automatic Emergency Braking turn on, to prevent the crash.

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.

Vehicle: 2023 Ford Mustang Mach-E (leased) The issue involves the cruise control system and steering wheel control layout (human-machine interface). Cruise control is unintentionally activated when attempting to use the turn signal due to the placement of the cruise control buttons. The vehicle is available for inspection upon request. On two separate occasions while using one-pedal driving, unintended cruise control activation caused sudden acceleration during low-speed turning maneuvers. The first incident occurred while signaling to turn into a parking spot. The second occurred while entering a left-turn pocket. In both cases, the unexpected acceleration created an immediate risk of collision with surrounding vehicles and required sudden panic braking to avoid an accident. The issue has occurred multiple times during normal driving but has not yet been formally reproduced or confirmed by a dealer or independent service center, and the vehicle has not yet been inspected by the manufacturer or other parties regarding this issue. No warning lamps, alerts, or messages appeared prior to the unintended acceleration. Cruise control engaged without driver intent and without advance warning.

When in cruise control, any speed, car suddenly accelerates This happens while driving, or sometimes after stopping and then resuming previous set speed. For example I was driving in cruise control at 38 mph, when the car suddenly sped to 50mph. Or when on a highway, driving at 55mph, the car suddenly accelerated to 70mph. Started about 3 weeks ago.

On 2 occassions in the past 2 week, our Mustang Mach E has accelerated on its own. In the first incident, it was a minor acceleration. It caught me by surprise as I was pulling up to a curb to drop off a passenger. It was easily stopped with brake pressure. In the 2nd incident, the acceleration was greater and more pronounced while pulling into a parking spot, requiring the pressure of both feet to quickly stop it before it went up onto a sidewalk and into a store front. It's never done this before, but certainly could cause an accident and was unsettling. We have not taken it to the dealer because it is random and not replicate-able. There were no warning lamps or error messages at the time. The vehicle was functioning and acting normal otherwise.

I was waiting in a drive thru behind a line of cars at a full stop for some time, so I was using One Pedal assist/Auto Hold. My car suddenly accelerated and slammed into the car in front of me.
