New Safety Recall: WRE-21 Impreza/Crosstrek Ignition Coil Replacement
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.

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.
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 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.

retailer inventory necessary steps should be taken to ensure the recall correction has been made before
selling or releasing the vehicle.

Dashboard available on subarunet.com to identify any vehicles with open recalls that may be in your
