Subarunet Announcement To: All Subaru Retailers From: Subaru of America, Inc. Date: May 13, 2021 UPDATE Safety Recall: WRE-21 Impreza/Crosstrek Ignition Coil Replacement Owner Notification Please be advised that owner notification will begin on June 1 and continue through June 11, 2021. Subaru of America, Inc. (Subaru) is recalling certain 2017-2019 model year Impreza and 2018-2019 model year Crosstrek vehicles to check and/or update the ECM programming, and to replace all four ignition coils in each vehicle. A total of 466,205 U.S. vehicles will be affected by this recall. This new recall supersedes Subaru’s previous WUQ-02 ignition coil reprogramming recall issued in October 2019. All vehicles previously affected by the WUQ-02 recall are now affected by this new recall, WRE-21, and must return to complete the WRE-21 recall repair. Affected Vehicles Model Year Carline Production Date Range 2017-2019 Impreza 4D 7/1/2016 – 6/17/2019 2017-2019 Impreza 5D 7/1/2016 – 6/17/2019 2018-2019 Crosstrek 5/09/17 – 5/08/2019 Not all vehicles in the production date ranges listed above are affected by this new recall. Coverage must be confirmed by using the Vehicle Coverage Inquiry function on subarunet.com prior to repair. This information is now available. • Any incomplete WUQ-02 recall coverage is now expired, and the repair procedures for recall number WRE-21 should be performed instead. • Vehicles that already had the WUQ-02 recall repair completed must return for the WRE-21 recall repair, even if one or more ignition coil(s) were previously replaced. Reason for this Recall Subaru has determined that the ECM reprogramming was effective for vehicles that were repaired under previous recall WUQ-02. However, as a result of further analysis, Subaru has determined that all four ignition coils should be replaced to prevent the condition described below. Under certain circumstances, the ignition coil may be energized longer than designed after the engine is OFF. If the ignition coil remains energized for too long, the internal temperature of ignition coil may increase which could cause a short circuit and a blown fuse. Safety Risk If a short circuit in the ignition coil occurs while the vehicle is in motion, the vehicle may experience a loss of motive power while driving without the ability to immediately restart the engine, increasing the risk of a crash. Description of the Remedy For all vehicles included in this recall, Subaru retailers will check and, if necessary, update the ECM programming, and replace all four ignition coils at no cost to the customer. If a certain DTC is found to be stored, Subaru will replace the front exhaust pipe at no cost as well. Please refer to the WRE-21 Product Campaign Bulletin on STIS for further details. Service, Parts, and Claim Instructions For detailed service, parts, and claim information, please refer to the WRE-21 Product Campaign Bulletin on STIS. Retailer Responsibility Any vehicles listed in any recall/campaign that are in retailer stock must be: ▪ Immediately identified ▪ Tagged or otherwise marked to prevent their delivery or use prior to repair ▪ Repaired in accordance with the repair procedures outlined in the Product Campaign Bulletin Retailers are to promptly perform the applicable service procedures to correct all affected vehicles in their inventory (used, demo & SSLP). Additionally, whenever a vehicle subject to this recall is taken into retailer inventory necessary steps should be taken to ensure the recall correction has been made before selling or releasing the vehicle. Please be sure to download a copy of your complete inventory report from the Vehicle Inventory Dashboard available on subarunet.com to identify any vehicles with open recalls that may be in your retail, CPO, and SSLP inventory. Affected vehicles will show an Open Recall column indicator (Y).

SUBARU OF AMERICA, INC. has decided that a defect, which relates to motor vehicle safety, exists in certain 2017-2019 Impreza vehicles and 2018-2019 model year Crosstrek vehicles. You received this notice because our records indicate that you currently own one of these vehicles. This recall replaces Subaru’s previous WUQ-02 ignition coil reprogramming recall issued in October 2019. All vehicles affected by the previous recall must return to complete the WRE-21 recall repair, even if the previous recall repair was completed. REASON FOR THIS SAFETY RECALL Subaru has determined that the ECM reprogramming was effective for vehicles that were repaired under previous recall WUQ-02. However, as a result of further analysis, Subaru has determined that all ignition coils should be replaced to prevent the condition described below. Under certain circumstances, the ignition coil may remain energized longer than designed after the engine is OFF. If the ignition coil remains energized for too long, the internal temperature of the ignition coil may increase which could cause a short circuit and a blown fuse. SAFETY RISK If a short circuit in the ignition coil occurs while the vehicle is in motion, the vehicle may experience a sudden loss of power while driving without the ability to immediately restart the engine, increasing the risk of a crash. WHAT SUBARU WILL DO Subaru will check and, if necessary, update the electronic control module (ECM) programming, and replace all four ignition coils in your vehicle at no cost to you. Additionally, in the unlikely event that a certain diagnostic trouble code (DTC) is found, Subaru will replace the front exhaust pipe including the catalytic converter at no cost to you. WHAT YOU SHOULD DO As mentioned above, all vehicles affected by the previous recall must return to complete the WRE-21 recall repair, even if the previous recall repair was completed. Please contact your Subaru retailer (dealer) immediately for an appointment to have this repair performed, at no cost to you. Bulletin Number: WRE-21R; Revised: 08/23/22 Page 11 of 12 HOW LONG WILL THE REPAIR TAKE? The time required for the ECM program check, DTC check, and ignition coil replacement is approximately one hour and ten minutes. However, if it is determined that the ECM needs to be reprogrammed, that reprogramming will require an additional twenty minutes. In the unlikely event that a certain DTC is found, the front exhaust pipe including the catalytic converter will need to be replaced. That replacement, if necessary, will require an additional fifty minutes. Your retailer can provide you with a better estimate of the overall time for this service visit, as it may be necessary to leave your vehicle for a longer period of time on the day of your scheduled appointment to allow your Subaru retailer flexibility in scheduling. For your convenience, your retailer may provide you with a loaner or rental vehicle, at no cost to you, until the repair is complete. OWNER INFORMATION Government regulations require that recall notifications be sent to the last known owner of record. That information is based primarily on state registration and title data. If you are a lessor of this vehicle, federal regulations require you to forward this notice to your lessee within ten days. If you have moved or sold your vehicle, please update this information online at www.subaru.com, select ‘Customer Support,’ then select ‘Address Update’ or ‘Ownership Update’ from the “Quick Links” menu. CALIFORNIA REGISTERED OWNERS The California Air Resources Board requires that emission related campaigns be completed prior to California’s vehicle registration renewal process; without this repair, you will not be able to register your vehicle during your next annual registration. Upon completion of this campaign, your California dealer will complete and provide you a “Proof of Correction Certificate.” If required, present the certificate to the California Department of Motor Vehicles (the “DMV”) when renewing your California registration as proof of campaign completion. If the DMV does not request the certificate, we recommend that you keep it for your records. In addition, the State of California requires that every vehicle must pass an emission test (SMOG Check) every two years and before it is sold. Without the repair we are providing at no charge, your vehicle may not pass this test. IF YOU HAVE PREVIOUSLY PAID FOR A REPAIR If you have already paid for repairs associated with this coverage, you may be eligible for reimbursement. Reimbursement consideration will be based on the amount an authorized Subaru retailer in your area would charge for the same repair. Please send the original service repair order, which has the name of the repair facility, date of repair, mileage at the time of repair, complete 17-digit vehicle identification number (VIN), and your name, with correct mailing address and telephone number to the address listed below.
