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.

We recently brough the Mach E in for a recall of the rear camera. We mention the front camera alerts. They said due to safety concerns, sometime when the back camera goes out it affects all cameras. When we picked up the car, they told use that the front camera, which controls active cruise control, self-driving and emergency stopping is not covered under the recall. How can this not be a safety issue. The cost to fix it is over $4000. Please let me know if there are any upcoming recalls. Thanks!

I was pulling into a parking lot at low speed when the car suddenly began accelerating rapidly on its own. Fortunately, when I hit the brakes it stopped without incident. However, if someone had been right in front of me at the time - a pedestrian or car - it could have resulted in a crash. I am certain that I didn't hit the accelerator, nor was it pushed by floor mats or anything like that. It is conceivable that when I was turning, my left palm activated the cruise control in some manner, but that scenario wouldn't explain the acceleration part. And frankly, I don't think that is what happened. I love the vehicle and am not trying to get anything out of it. I am a capable driver with good reflexes and experience. I was able to stop it, but if this were to happen to a new driver or senior driver it could result in a crash. I looked on reddit and many others report exact same issues.

While driving my 2021 Ford Mustang Mach-E, the front electric drive unit failed suddenly with no warning signs, warning lights, unusual noises, or any prior indication of a problem. During the failure, multiple fault messages appeared on the instrument cluster, including warnings that disabled adaptive cruise control and indicated the all-wheel-drive system was no longer functioning. The vehicle began to vibrate severely, feeling as though it was driving over rumble strips. As I slowed down, the front of the vehicle became extremely clunky and exhibited abnormal drivetrain behavior. Shortly afterward, the vehicle became undrivable and could no longer be operated under its own power. It had to be towed to a Ford dealership, where I was informed that the front electric drive assembly had failed and required replacement. This is the second time this exact component has failed on the same vehicle. The first front electric drive assembly failed at approximately 33,000 miles and was replaced under warranty. The second failure occurred at approximately 102,000 miles with no warning. I believe this repeated and sudden failure of a critical drivetrain component presents a significant safety concern because it can leave drivers stranded without warning and results in an unexpected loss of propulsion while operating the vehicle in traffic.

Ongoing issues with forward facing radar preventing collision assistance and adaptive cruise control along with lane keep assist from working. Ford knows about this. There is even a TSB. A car manufactured in an era that requires collision prevention should not be allowed to have significant camera faults that prevent safety systems from functioning properly. Unfortunately, the plan for many is to continue operating without these important safety features and crashes will occur as a result. Ford should be required to properly fix their radar system functionality in the Mach-E.

The front camera system does not function which causes all forward collision safety features to become unavailable, as well as any cruise control or automatic high beam lights. Seems to be a common issues and is related to faulty fiber optic cables.

The car gives two messages, "Front Camera Fault Service Required" and "Pre-Collision assist not available." The cruise control does not work, however, the front camera does work. I had the vehicle scan done at the Ford dealer and was told it needs a 7 hour software update, after which it may need cables replaced. I do not understand how software goes bad. I do understand something may have happened to cables but that would not be checked until they had charged me $ 1,400 for a software update. This is a safety issue and, from what I read on the Mach E forum, is not where near unique to my vehicle.

Vehicle: 2021 Ford Mustang Mach-E Component: Image Processing Module A (IPMA) / Front Camera / Forward Collision Avoidance System The IPMA and front camera system have failed, disabling Pre-Collision Assist, AEB, forward collision warning, and adaptive cruise control while driving. The vehicle is available for inspection upon request. Warning messages "Front Camera Fault Service Required" and "Pre-Collision Assist Not Available" first appeared August 24, 2022 and have recurred consistently over nearly four years. No accident, physical damage, or obstruction was present at any occurrence. This failure puts safety at risk by silently disabling AEB and forward collision warning during normal driving — systems a driver may depend on in an emergency braking situation with no advance notice they are unavailable. The problem was confirmed by a Ford dealership in February 2026. Their repair order documents: "RAN IPMA SELF TEST AND FOUND DTC SET U3000-49... HARDWARE TEST FAILED... FOUND TSB RELATED REC REPLACE MODULE." The dealer contacted Ford, who authorized 50% off the module replacement only, characterizing it as a "loyal customer discount" rather than a warranty or goodwill repair. I declined to pay for the fix. the federal safety agency Campaign 11028164 (superseding TSB 25-2156) covers this exact failure. Ford's own TSB acknowledges the defect and the dealer confirmed it applies to my vehicle, yet owners are being quoted up to $8,000 for a known safety system failure. I'm requesting the federal safety agency investigate whether this warrants a recall. First occurrence: August 24, 2022 (mileage not recorded) Service visit: February 17-18, 2026 at 80,029 miles Current mileage: 83,988 Attachments: photos of both fault messages, dealer invoice
