2023 Ford Mustang Mach E problems

SEAT BELTS

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.

UNKNOWN OR OTHER

Impacts: Electric system software & fools/locks/linegae. The EV vehicle has suffered a catastrophic, complete failure of its central software architecture, specifically impacting the APIM module and RDS system. Ford's internal In-Vehicle Technology (IVT) records confirm this failure originated in December 2025 while vehicle was fully under its 3-year bumper-to-bumper warranty. Because vehicle's underlying diagnostic and software infrastructure is completely frozen in an unresolved "updating" loop, the vehicle's onboard diagnostic tools are entirely incapable of reading or reporting critical hardware and structural component failures. Initial service was May 26. This software failure has caused severe, active safety hazards. In July 2026, the driver-side door latch completely failed to secure. Because software is bricked, no diagnostic code or dashboard warning was generated. As a 100% disabled driver, I was forced to drive 35 minutes home from an oncology medical appointment physically holding the driver’s door shut at speed on public roads to prevent it from swinging open. Furthermore, vehicle's network connectivity has completely shut down while driving on 3 separate occasions. During door latch failure, I was trapped in a rural area with zero cellular service. Because onboard telematics and modem systems are frozen and failing to receive critical safety patches, vehicle's SOS Post-Crash Alert System and tracking telemetry are severely compromised. If an accident or ejection had occurred due to the door latch failure, emergency services would have had no automated tracking link. Ford has failed to repair this after multiple extended dealer stays and has admitted through their IVT department that vehicle is unfixable due to massive never before seen software failure via standard service and requires manufacturer buyback. Dealer files att show no vehicle updates since Feb 2026 tho IVT confirmed May 28 not updates since Dec 2025 from Ford known software glitch.

SERVICE BRAKES

My 2023 Ford Mustang Mach-E GT experienced a sudden electronic parking brake failure. The vehicle displayed a parking brake fault warning, and the electronic parking brake became stuck in the engaged position and would not release despite repeated attempts and restarting the vehicle. The failure completely immobilized the vehicle and required Ford Roadside Assistance to tow it to an authorized Ford dealership. The Ford dealer diagnosed the issue in writing as: “REAR EPB HARNESS CORRODED; STARTING TO CORRODE ON RR AS WELL; RECOMMEND REPLACING BOTH REAR PIGTAILS WITH UPDATED STYLE.” The dealer therefore found corrosion affecting the electronic parking brake wiring on one rear side and corrosion beginning on the other side. Both rear EPB pigtails are being replaced with an updated-style component. This failure appears substantially similar to the electronic parking brake wiring/connector issue Ford previously identified in Customer Satisfaction Program 22P31 for certain earlier Mustang Mach-E vehicles. Ford's documentation for 22P31 states that damage to the EPB wiring can result in a parking brake malfunction and, in some cases, an inability to disengage the parking brake. My 2023 vehicle is apparently not included in that program despite experiencing a very similar failure mode. I am submitting this complaint because corrosion of the electronic parking brake wiring on a relatively new vehicle resulted in the parking brake becoming permanently engaged and the vehicle being completely immobilized. The dealer also found corrosion developing on the opposite-side EPB wiring and recommended replacement of both sides with updated-style pigtails. I believe NHTSA should evaluate whether this EPB wiring/connector corrosion condition extends to 2023 Mustang Mach-E vehicles beyond the population originally identified by Ford.

FORWARD COLLISION AVOIDANCE: WARNINGS

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!

There was a message " Motor coolant over temperature '' popped up on 05/21/2026. Sent the car to Ford dealership for diagnosing it .Found out there was a big hole on the Motor casing . Told them, there was a crash on 04/14/2026. After diagnosing ,they did not know what caused the issue. We resubmitted the case to AAA insurance company for the sub-claim, they told me that the issue was not related to the previous crash . On the ford side, Car warranty did not cover the replacement of motor case and the repair cost. But it is really the quality issue of the part ( the casing of the motor)made by the Ford company.

In the event of a differential pinion shaft failure, the customer may experience a loss of motive power and/or unintended vehicle movement with Park requested if the parking brake is not applied. A loss of motive power or unintended vehicle movement increases the risk of a crash

Vehicle in question had problems since day. One computer was affected was never fixed. Many problems ended up in agency for repairs a total of 9 1/2 months and I’ve only have a three year lease on the vehicle and have not been able to use it fully because of electrical and further issues. Litigation found with my attorneys and Ford attorneys, that the vehicle had multiple problems and was issued by a judge, repayment and penalties.

POWER TRAIN

While I was driving the brakes did not work. I had to slam on the brakes in order to stop the car. The back portion of the car then skid. The following warnings were sent to the phone and appeared on the dashboard as well. There were more on the dashboard but since I was driving I focused on trying to maneuver the car and not reading the dashboard. Not knowing what happened I continued to drive to duplicate the issue. The brakes were consistently only working when slamming on the brakes (and skidding). There was no traffic, allowing us to rely on driving slow speeds and letting the car to come to natural stops. We took it to the dealership immediately who were unable to duplicate. They diagnosed it as a network overload and attempted to release the car back to us. Currently working with a Ford Advocate as a Network Overload will shut our brakes off again. It's just a matter of when. Which is why they can't duplicate it. They can't predict when the Ford Network that communicates to the MachE braking mechanism will overload again.

Had a warning on my vehicle that said Electric Park Brake fault. Prior year vehicles had this issue that resulted in a recall. When the warning light came on the dealership was able to get the car in and fix it immediately.
