If a vehicle already has accumulated more than 150,000 miles, this coverage will last through April 30, 2024. AFFECTED VEHICLES Vehicle Model Year Assembly Plant Build Dates Mustang Mach-E 2021 Cuautitlan February 24, 2020 through December 23, 2021 Mustang Mach-E 2022 Cuautitlan August 16, 2021 through February 23, 2022 US population of affected vehicles: 36,427. Affected vehicles are identified in OASIS and FSA VIN Lists. Note: Monitor OASIS before opening an RO and/or beginning a repair. Parts purchased for an FSA can be returned for credit if required. See the EXCESS STOCK RETURN details in Attachment II for more information. REASON FOR THIS PROGRAM In some of the affected vehicles, the Electronic Park Brake (EPB) may not function due to damaged or broken wiring. Customers may experience an audible chime, a wrench light, and a message on the Instrument Panel Cluster (IPC) specifying there is a “Parking brake failure, service immediately”. Some customers may be unable to disengage the park brake resulting in brake drag while driving accompanied by a constant minder and chime. The vehicle design will allow the affected vehicles to remain stationary on a grade even with a non-functioning EPB. SERVICE ACTION Dealers are to replace the connector to the Electronic Park Brake on the rear calipers. This service must be performed on all affected vehicles at no charge to the vehicle owner. OWNER NOTIFICATION MAILING SCHEDULE Owner letters will not be mailed for this program.  Copyright 2023 Ford Motor Company ATTACHMENTS Attachment I: Administrative Information Attachment II: Labor Allowances and Parts Ordering Information Attachment III: Technical Information QUESTIONS & ASSISTANCE For questions and assistance, contact the Special Service Support Center (SSSC) via the SSSC Web Contact Site.

REPLACED FSA PARTS INSPECTION AND SIGN OFF Effective March 1st, 2021 all parts replaced as part of an FSA repair with a repair order open date of March 1st, 2021, or later must be inspected and signed off on the repair order by a member of your dealer fixed operations management team or an employee of the task has been delegated to. If the task is to be delegated to a non-management employee, the employee needs to be someone other than the technician who completed the repair and needs to understand the importance of completing this task consistently and accurately. • All parts replaced as part of an FSA repair should be returned to the parts department following the Warranty Parts Retention and Return Policies. • Inspect the replaced parts to verify the FSA repair was completed. • If the FSA repair is found to be complete, the designated employee signs the repair order line or parts return stamp area (electronic or hand signed) for the FSA repair indicating the parts were inspected and validated to have been replaced. • After the parts have been inspected, they should be handled based on the guidance in the parts status report in the Online Warranty System (Hold, Return, CORE, Scrap, etc.). • This process is subject to review during warranty audits for FSA repairs with a repair order open date of March 1st, 2021 or later. Any eligible FSA claims requiring parts replacement found not to have been inspected and signed off during a warranty audit will be subject to chargeback and consideration for enrollment into the Dealer Incomplete Recall Repair Process. Note: Other approvals (electronic or handwritten) for add-on repair lines, dealer-owned vehicle repairs, and repeat repairs do not qualify as FSA parts inspection approvals. The post-repair FSA parts inspection process (electronic or handwritten) is independent of other warranty approval requirements. The approval by the designated employee implies that the FSA parts were found to be replaced and must be able to be clearly identified on the Repair Order. If multiple FSAs require approval on a single Repair Order, each applicable occurrence will require individual post-repair approval by the designated employee.
