2023 Ford Mustang Mach E: sudden unintended acceleration

Filed Sep 12, 2026 · Acceleration, Electrical · VA

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.

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.

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.

While driving the 2023 Ford MachE in 1 Peddle mode Friday 12 July 2024. I had to suddenly brake due to a car cutting of the car in front of me to make an illegal turn. I applied the brakes (HARD) and my car came to a complete stop. Just as I was breathing a sigh of relief, and waiting for the still parked car in front of me to move. On I released my foot of the brake (the car should have held in place). However, warning lights sensors started beeping going crazy as the car lunged forward. It caused me to hit the car in front of me. The lunge was so forceful that for a moment I thought another car had rear-ended me and pushed me into the stopped car in front of me. I did not have time to see all of the alerts flashing on the dash as they were flashing as the car was propelled forward. The other car did not sustain any damage. However my car car did. While waiting on the Police to come make a report I did use the in car engineer feedback and recorded a message notifying Ford that my car had lunged forward. On Monday 15 July I called the Ford BEV team to tell them what happened. Was advised to take it to a dealership to be checked out. The dealership ran diagnostics and updated the car via a technical service bulletin. 24-2187 issued on 07 June 2024. Prior to me taking my car to the dealership I also came to your website and there were no active recalls and no mention of this bulletin. The bulletin address the 1 pedal drive fault. I was not aware of this TSB. I have documented over 50 posts related to this error and fail.
