Production Dates : MAR 17, 2021 – MAY 16, 2022 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : Over time, moisture intrusion may cause the inhibitor switch to become inoperative. An inoperative inhibitor switch may result in the backup lamps not illuminating when in reverse gear, the rear-view monitor not displaying, the transmission gear select indicator in the instrument panel not being displayed, or inability to start the engine. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : An inoperative inhibitor switch may result in the backup lamps not illuminating when in reverse gear, the rear-view monitor not displaying, each of which increases the risk of a crash. Description of the Cause : A worn welding jig resulted in an insufficient weld thickness between the stator and cover. This condition may result in a loss of sealing integrity and allow water intrusion. The moisture may then cause electrical corrosion leading to failure of the switch. Identification of Any Warning that can Occur : If the inhibitor switch were to fail, a driver may notice one or more warning signs including the rear-view monitor not being displayed, the backup lamps not illuminating, no transmission gear selection displayed in the instrument panel; Malfunction Indicator Lamp (MIL) displayed in the instrument panel or experience the inability to start the engine. Involved Components : Part 573 Safety Recall Report 23V-755 Page 4 The information contained in this report was submitted pursuant to 49 CFR §573 Component Name 1 : INHIBITOR SWITCH Component Description : SWITCH-INHIBITOR Component Part Number : 31918AA120 Supplier Identification : Component Manufacturer Name : TOKAI RIKA CO., LTD. Address : 3-260 Toyota, Oguchi-cho, Niwa-gun Aichi Foreign States 480-0195 Country : Japan Chronology : June 2021 – Subaru received the first technical report from the U.S. market indicating ‘D’ or ‘R’ was not displayed on the combination meter when in drive or reverse ranges, respectively. After examining the part, no abnormality was found. June 16, 2021 – Supplier rotated the welding jig out of the production process under normal maintenance. July 2021 – June 2022 – Additional failed parts were collected for further investigation. While most did not find a conclusive cause, later parts collected began to show signs of water intrusion. June 2022 – September 2022 – The supplier conducted testing to reproduce the failure mode. The cause was determined to be a defect in the welding jig used from February to June 2021. August 2022 – July 2023 – Subaru continued to monitor field data. During this period, seven (7) new nondealer field reports were submitted and all non-dealer field reports, including those prior to this period, involved alleged symptoms such as check engine light illumination or inability to start the engine and no cases indicated a crash or injury. July 2023 – October 2023 – Subaru escalated this topic for further consideration of field action after a data analysis predicted an increasing upward trend in claims. Following escalation, Subaru determined the extent of potential symptoms that could be caused by an inoperable inhibitor switch. Based on the results of this multidisciplinary review, Subaru reassessed this topic for safety and noncompliance implications. November 2, 2023 – Out of an abundance of caution, Subaru decided to conduct a voluntary safety recall. Subaru is aware of twelve (12) technical reports in the U.S. market. Subaru is not aware of any crashes or Part 573 Safety Recall Report 23V-755 Page 5 The information contained in this report was submitted pursuant to 49 CFR §573 injuries resulting from this condition. Description of Remedy : Description of Remedy Program : For all the potentially affected vehicles, Subaru dealers will replace the inhibitor switch with a new one at no cost to the customer. Subaru will provide reimbursement to owners for repairs according to the general plan submitted in May 2022. How Remedy Component Differs from Recalled Component : The remedy component has been manufactured with an appropriate weld. Identify How/When Recall Condition was Corrected in Production : The recall condition was corrected at the supplier on June 16, 2021. Recall Schedule : Description of Recall Schedule : Dealer notification is expected to occur on November 10, 2023 Owner notification is scheduled to begin on or about January 8, 2024 Planned Dealer Notification Date : NOV 10, 2023 – NOV 10, 2023 Planned Owner Notification Date : JAN 08, 2024 – JAN 08, 2024 * NR – Not Reported

Subarunet Announcement To: All Subaru Retailers From: Subaru of America, Inc. Date: November 10, 2023 New Safety Recall: WRQ-23 Inhibitor Switch Replacement Subaru of America, Inc. (Subaru) has initiated a safety recall for certain 2021 model year Crosstrek vehicles, certain 2022 model year Forester, and certain 2021-2023 model year Legacy and Outback vehicles. Description of the Defect and Safety Risk The vehicles included in this recall may contain an inhibitor switch that was manufactured with an insufficient weld between the switch stator and cover which may allow water intrusion. Over time, moisture intrusion may cause the inhibitor switch to become inoperative. An inoperative inhibitor switch may result in the backup lamps not illuminating when in reverse gear, the rear-view monitor not displaying, the transmission gear select indicator in the instrument panel not being displayed, or inability to start the engine. Remedy For all the potentially affected vehicles, Subaru dealers will replace the inhibitor switch with a new one at no cost to the customer. The recall repair procedure will be forthcoming in a subsequent subarunet announcement. Affected Vehicles A total of 95,830 U.S. vehicles will be affected by this recall, as listed below. Not all vehicles in the production range listed below are affected by this recall. Coverage must be confirmed by using the Vehicle Coverage Inquiry function on subarunet.com prior to repair.
