NHTSA Complaint #11711513 — 2022 FORD MUSTANG MACH E

Vehicle: 2022 Ford Mustang Mach-E Mileage at failure: ~36,800 miles Complaint Description: The left rear electronic parking brake (EPB) wiring harness/connector failed, resulting in a parking brake fault and abnormal braking behavior. This component is not a wear-and-tear item and is located in a fixed, protected area of the vehicle. It is not subject to routine maintenance or driver interaction. The failed wiring harness was inspected by an authorized Ford dealership and is available for further inspection upon request. This failure put safety at risk because the electronic parking brake is a safety-critical braking system. The fault created uncertainty regarding proper engagement and release of the parking brake, increasing the risk of unintended vehicle movement when parked and reduced confidence in braking reliability while driving. The problem was confirmed and diagnosed by a Ford dealership, which determined the wiring failure developed over time due to moisture intrusion and corrosion, not misuse, accident damage, or normal wear. The vehicle and component were inspected by an authorized Ford dealership. Ford Motor Company reviewed the repair documentation through Ford Customer Care but did not dispute the diagnosis. The component has not been inspected by police or insurance representatives. A parking brake fault warning message appeared shortly before diagnosis, accompanied by abnormal braking behavior. There were no prior accidents, vehicle modifications, or external damage related to the failure. This failure is identical to a known defect already acknowledged by Ford in Customer Satisfaction Program 22P31, which covers EPB wiring harness connector failures on other 2021–2022 Mustang Mach-E vehicles. Although my VIN was excluded, the same non-wear safety defect occurred within the same model year, indicating a broader safety concern beyond the original VIN population.
