2023 FORD MUSTANG MACH E Complaints
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.;
