Date: April 15, 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 will supersede Subaru’s previous WUQ-02 ignition coil reprogramming recall issued in October 2019. All vehicles previously affected by the WUQ-02 recall will be affected by this new recall, WRE-21, and must return to complete the WRE-21 recall repair.
|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 recall. Coverage must be confirmed by using the Vehicle Coverage Inquiry function on subarunet.com prior to repair. WRE-21 vehicle coverage information will be available for all affected VINs next week.
When the WRE-21 recall coverage information is activated in the system, any open WUQ-02 recall coverage will be expired. Upon expiration of the open WUQ-02 recall coverage, the repair procedures for recall WRE-21 should be performed instead.
Over the next several weeks, prior to owner notification, Subaru will be receiving air shipments of the parts needed to support the launch of this new recall. Therefore, the status of the WRE-21 recall will display as “Open – Limited Parts Available” until the owner notification letters are released. This status is for informational purposes and will not prevent the ability for retailers to perform and claim reimbursement for this repair prior to owner notification.
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 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. If a short circuit 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.
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 for further details.
Service, Parts, and Claim Instructions
Detailed service, parts, and claim information will be forthcoming and will be made available in the WRE-21 Product Campaign Bulletin on STIS next week.
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 will notify affected vehicle owners by first class mail within 60 days. Retailers will be advised when the notification is scheduled.
Chronology of Defect / Noncompliance Determination
Provide the chronology of events leading up to the defect decision or test data for the noncompliance:
October 17, 2019 – Subaru submitted voluntary safety recall 19V743.
November 18, 2019 – Subaru received the first technical report from a foreign market alleging a misfire occurring shortly after completion of the recall remedy. Subaru collected the part for further evaluation.
November 2019 – March 2021 – Subaru conducted an investigation in cooperation with a third-party company. In March 2020, it was confirmed that the ignition coil mold resin condition was a contributing factor. In July 2020, as a result of analyzing the residual strain characteristics in the mold resin, Subaru confirmed that residual strain is generated by repeated heat cycling of the mold resin, and that the resin residual strain does not increase if the temperature remains low enough. In December 2020, as a result of investigating the correlation between semiconductor strain and heat generation, Subaru confirmed that if the semiconductor is strained, the current and temperature increases. In March 2021, simulation showed that residual strain in the mold resin and semiconductor created prior to ECM reprogramming could continue to accumulate, even under normal-duration ignition coil energization timing. The results also showed that mass-produced ignition coils that were never exposed to energization for longer than expected durations would not accumulate strain.
April 8, 2021 – In certain foreign markets, the subject vehicle population is equipped with an automatic start/stop feature. Field data in these markets serves as an early warning indicator for markets that do not offer an automatic start/stop feature, such as the U.S. market. There have been no additional VOQs and 18 additional non-dealer field reports in the U.S. market. Based on the results of the investigation and out of an abundance of caution, Subaru decided to conduct a voluntary safety recall to equip potentially affected vehicles with new ignition coils after the updated ECM programming has been applied.
Subaru is not aware of any reported accidents or injuries related to this condition.
SUBARU ANNOUNCES TWO NEW RECALLS

- No accidents or injuries have been reported related to the recalls
Subaru of America, Inc. announced that it will voluntarily conduct two separate recalls. Subaru is announcing these recalls to encourage each owner of an affected vehicle to contact an authorized Subaru retailer as soon as they receive notification of this recall from Subaru of America.
The recalls involve the following vehicles:
- 2017-2019 Impreza and 2018-2019 Crosstrek models
- 2019 Subaru Forester and 2019 Subaru Crosstrek models
The first recall is to check and/or update the engine control module (ECM) programming and to replace all ignition coils which could, over time, degrade and cause starting or stalling issues. Incident rates are extremely low, but Subaru is conducting the recall out of an abundance of caution. This recall covers 466,205 vehicles comprising 2017-2019 Impreza and 2018-2019 Crosstrek models. No accidents or injuries have been reported due to this issue.
The second recall is for 2019 Subaru Forester and 2019 Subaru Crosstrek models to examine and re-torque bolts on the rear stabilizer bracket which could, over time, come loose.
