Production Dates : DEC 01, 2019 – DEC 12, 2021 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : A manufacturing defect in one or more of the vehicle’s high voltage battery cells may result in a lower capacity cell. In certain cases, the low capacity cell will develop an internal short circuit. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : In the event of a high voltage battery cell internal short, customers may experience a battery power off. A battery power off will result in a loss of motive power with coasting, increasing the risk of crash. Customers will continue to have 12V accessories, steering, and braking control. If a second, still undetermined, factor is present with the folded tab, the customer may experience battery thermal venting potentially resulting in a vehicle fire, increasing the risk of injury. Description of the Cause : The root cause of this condition is partially due to the presence of a folded anode tab within a cell in the high voltage battery. The folded anode tab is introduced during the cell manufacturing process. A folded tab may result in a cell with lower capacity. In addition to the folded tab, a second factor must be present or induced for a cell internal short with thermal venting to result. This factor is still unknown and under investigation. Identification of Any Warning that can Occur : Customer will experience a Malfunction Indicator Light (MIL) in the event of a high voltage battery cell internal short. Part 573 Safety Recall Report 23V-626 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 Involved Components : Component Name 1 : UNT ASY BAT H/V TRCT Component Description : High Voltage Battery Pack Component Part Number : L1M* 10B759 AP Supplier Identification : Component Manufacturer Name : LGES Address : 1 LG Way Holland 49423 Country : NR Chronology : Chronology is provided as an attachment. Description of Remedy : Description of Remedy Program : Owners will be notified by mail and instructed to take their vehicle to a Ford or Lincoln dealer to have a Battery Energy Control Module (BECM) diagnostic test performed. If a cell capacity anomaly, indicative of a folded anode tab introduced during cell manufacturing, is detected during the test, dealers will replace the high voltage battery pack. There will be no charge for this service. Ford provided the general reimbursement plan for the cost of remedies paid for by vehicle owners prior to notification of a safety recall in May 2023. The ending date for reimbursement eligibility is estimated to be December 14, 2023. Ford will forward a copy of the notification letters to dealers to the agency when available. How Remedy Component Differs from Recalled Component : Replacement high voltage battery packs will have cells that are produced post-supplier manufacturing process improvements.

Box 1904 Service Engineering Operations Dearborn, Michigan 48121 Ford Customer Service Division September 13, 2023 TO: All U.S. Ford and Lincoln Dealers SUBJECT: NEW VEHICLE DEMONSTRATION / DELIVERY HOLD – Advance Notice – Safety Recall 23S53 Certain 2020-2022 Model Year Aviator and Explorer Plug-in Hybrid Electric Vehicles (PHEV) – High Voltage Battery Diagnostic Inspection AFFECTED VEHICLES Vehicle Model Year Assembly Plant Build Dates Aviator PHEV 2020-2021 Chicago Assembly June 28, 2019 through September 26, 2020 2021-2022 Chicago SHO Center September 14, 2020 through May 23, 2022 Explorer PHEV 2020 Chicago Assembly July 09, 2019 through September 24, 2020 2021-2022 Chicago SHO Center September 14, 2020 through March 16, 2022 US population of affected vehicles: 2,952. Affected vehicles are identified in OASIS and FSA VIN Lists. REASON FOR THIS SAFETY RECALL In some of the affected vehicles, a manufacturing defect in one or more of the vehicle’s high voltage battery cells may result in a cell with lower capacity. In certain cases, the low-capacity cell will develop an internal short circuit. Customers will experience a Malfunction Indicator Light (MIL) in the event of a high voltage battery cell internal short. Customers may also experience a loss of motive power, increasing the risk of a crash. Customers will continue to have 12-volt (V) accessories, steering, and braking control. Customer may also experience battery thermal venting potentially resulting in a vehicle fire, increasing the risk of injury. NOTE: Certain vehicles were determined to not be at risk due to battery cell capacity information available through connected vehicle data and therefore removed from the recall population. Ó Copyright 2023 Ford Motor Company SERVICE ACTION DO NOT DEMONSTRATE OR DELIVER any new in-stock vehicles involved in this safety recall. For new vehicle storage guidelines, refer to EFC13033. A complete Dealer Bulletin will be provided to dealers in the 4th quarter of 2023 when it is anticipated that software and repair instructions will be available to support this safety recall. IMPORTANT: Dealers should open a Repair Order (RO) only when a full dealer bulletin is published. Opening an RO against an Awareness or Advance Notice will result in warranty rejections against a recall. CUSTOMER NOTIFICATION Owners of record will be notified via first-class mail after repair instructions and parts ordering information have been provided to dealers. PLEASE NOTE: Federal law requires dealers to complete this recall service before a new vehicle is delivered to the buyer or lessee. Violation of this requirement by a dealer could result in a civil penalty of up to $26,315 per vehicle. Correct all vehicles in your new vehicle inventory prior to delivery. DEALER-OPERATED RENTAL VEHICLES The Fixing America’s Surface Transportation (FAST) Act law effective June 2016 prohibits a rental company from selling, renting or leasing vehicles subject to a safety or compliance recall. Please consult your legal counsel for legal advice. QUESTIONS & ASSISTANCE For questions and assistance, contact the Special Service Support Center (SSSC) via the SSSC Web Contact Site.
