What 113 owners told NHTSA about the 2023 Ford Mustang Mach-e Bev Bev

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.

Dear NHTSA Team, I am writing to urgently raise concern and seek answers regarding what appears to be a systemic safety issue affecting vehicles equipped with Advanced Driver Assistance Systems (ADAS) and self-driving technologies. I have personally experienced repeated and dangerous incidents of phantom braking, overcorrection, and loss of control while driving a 2019 Toyota Prius. The car suddenly brakes, swerves, or pulls sharply when it detects shadows, road inclinations, or mild curves — making it unsafe to drive, especially at highway speeds. These events occur without any driver error. To make things worse, this issue is not limited to one brand or vehicle. Over the past year, I have driven and rented multiple cars from different brands and models through rental companies, and many of them presented the exact same unsafe behavior — unpredictable braking, steering correction, and traction instability. This clearly indicates that the issue is industry-wide, not isolated to a single manufacturer. I have been a professional rideshare driver for over five years, completing more than 500,000 miles without a single accident or ticket. Since October 2023, these vehicle behaviors have made it nearly impossible for me to continue working safely. This situation has destroyed my livelihood — I am now three months behind on rent, my mental health has been severely impacted, and I am facing homelessness for the second time in two years. All of this has happened because of unsafe technology that drivers cannot fully disable, even when it is clearly malfunctioning. I respectfully ask NHTSA: Why are automakers allowed to release and maintain these unsafe systems on public roads? Why do drivers not have the right to safely disable malfunctioning ADAS or self-driving features, like any other electronic system that can be shut down in an emergency? When will NHTSA take meaningful action to stop these dangerous practices before more lives are affected?

I’m writing this message out of frustration, exhaustion, and genuine concern for public safety. Over the past months, I’ve been renting and driving multiple cars from different brands and models — Toyota, Subaru, Nissan, and now a 2023 Ford Mustang Mach-E and all of them show the same dangerous behavior: sudden phantom braking for no reason, traction control malfunctioning, throwing the car from side to side, unstable handling, especially on highways or during light rain. This is not an isolated case it’s happening across several brands and systems, which makes me question what is really going on. Why are drivers being forced to deal with unreliable technology that clearly isn’t ready for real-world conditions? Are these systems being tested using real drivers as data sources to “teach” self-driving cars how to handle special situations? Because that’s what it feels like we are being used without consent, forced to correct constant software mistakes that could cost lives. This situation has destroyed my professional and financial stability. I work as a rideshare driver (Uber and Lyft), and passengers have reported me as “unsafe” because the car suddenly brakes or moves erratically something completely out of my control. I’ve lost access to stable work, fell behind on my car payments, and ended up returning my own vehicle because of all the expenses and stress trying to fix something that was never broken in the first place. And I have to ask: Why did NHTSA approve a regulation that prevents drivers from fully turning off these driver assistance systems? In what world does it make sense for a safety-critical technology to have no emergency off switch? In any other context like electricity we have breakers to stop the system when it becomes unsafe. Cars should be no different. I’ve lost almost everything I worked for because of this. Please, take this seriously. People’s lives, jobs, and mental health are being destroyed by technology that we can’t control.

Ford Motor Company Dear Ford Customer Service Team, I am writing as a highly disappointed owner of a Ford (specify model, e.g., Mustang Mach‑E), having observed a dramatic unexplained jump of over 10,000 miles on my vehicle’s odometer in just three months. I firmly reject the insinuation that I drove that distance—I maintain an accurate charging and usage log proving otherwise—and I demand a refund of my warranty payment plus a prompt and transparent investigation. Key Facts & Concerns 1. Sudden mileage spike (~10,000 miles in 3 months) • I did not charge or drive anywhere near that distance. My charging logs and event logs—comprehensively detailed—show a maximum of [X] miles total for that period. • The odometer reading is simply inconsistent with verifiable usage data. 2. Likelihood of system error or tampering • Similar issues have been documented in EVs: • Tesla vehicles are currently under multiple lawsuits alleging artificially inflated odometer mileage, sometimes by as much as 15–117%—accusations that have triggered a proposed class-action in California and garnered widespread reports and press coverage    . • Ford EV owners have also flagged odometer anomalies—both underreporting and overreporting, including a Ford Lightning report revealing odometer mismatch in a vehicle health report (). 3. Legal precedent and consumer protection • Odometer manipulation—even unintentional—is taken seriously under federal law (Federal Odometer Act), with strict penalties for tampering  . • Odometer discrepancies significantly affect warranty eligibility and residual vehicle value. What I Want Ford to Do 1. Full refund of the prorated warranty cost, as it has been voided unfairly by incorrect mileage totals. 2. Comprehensive odometer and software audit of my vehicle. I request a certified statement of findings. 3. Corrected mileage records and warranty reinstatement based on actual usage. 4. Clear, documented communication detailing how this issue

The vehicle regularly, and at random times, will drop out of the chosen drive setting and go to the default "Engage" mid-level setting. This changes the driving dynamics, such as pedal pressure required to move the car, and the sensitivity of the steering. If the driver was in "Unbridle", for example, the car will immediately lose speed and steering sensitivity, while if the driver was in "Whisper", the car will lurch forward. This has happened at city speeds, highway speeds, and even while at a stop in a line of cars. The stop is especially dangerous, as 1-pedal drivers would expect the car to be fully stopped, but it still lurches forward towards people or other cars. Temperature of the engine and battery does not seem to be a factor, as this happens in all conditions. It appears to be a dangerous software error.
