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.

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.

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.

Intermittent issue with the driver seat belt sensor which illuminates the restraints indicator warning light. Message sent in FordPass app says: "The restraints control module has detected a fault with the driver seatbelt buckle sensor circuit" Consultation with the dealership indicated that when the restraints warning light is illuminated the airbags become disabled. However, stopping the vehicle, turning it off, removing and reinserting the seatbelt into the buckle, and starting the vehicle clears the warning light. This is extremely intermittent and replication is difficult.
