PRODUCT CAMPAIGN BULLETIN
APPLICABILITY:
SUBJECT:

2019-2022 Crosstrek Hybrid

NUMBER: WRD-23R
DATE: 04/24/23

12V Inverter Connector Corrosion

REVISED: 10/26/23
NHTSA ID: 23V-080

Subaru of America, Inc. (Subaru) is initiating a new safety recall for certain 2019-2022 model year
Crosstrek Hybrid vehicles.
Description of the Defect and Safety Risk
The harness terminal that supplies low-voltage power from the converter to the 12V battery may
corrode, and over time, could cause the terminal to break. If the terminal breaks, the 12V battery may
not recharge as a result of this condition.
If the harness terminal breaks and the 12V battery is unable to recharge, the vehicle may experience a
loss of motive power, increasing the risk of a crash.
Remedy
For all affected vehicles, Subaru will replace the converter terminal mounting bracket with a new
bracket with improved isolation. If there is no corrosion found on the terminals of the 12V output
harness, a protective rubber cap will be installed on the terminals. If corrosion is found on the
terminals, Subaru dealers will replace the 12V output harness, including the terminals, with a new
one.
Affected Vehicles
A total of 8,413 U.S. Crosstrek Hybrid vehicles will be affected by this recall, as listed below:

Retailer Responsibility
Please be advised that it is a violation of Federal law for a dealer to deliver a new motor vehicle
covered by a recall under a sale or lease until the defect is remedied. Therefore, any Authorized
Subaru Retailer failing to perform the applicable service procedures to correct all affected vehicles
in their inventory prior to the vehicle being placed in service may be subject to civil penalties of up
to $26,315 per violation (i.e., for each vehicle), as provided in 49 CFR §578.6 and will also be in
breach of the Subaru Dealer Agreement.
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). 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.
Owner Notification
Subaru notified affected owners of this recall with an interim notification letter on April 14, 2023.
Owners will be renotified by first class mail on May 12, 2023, and will be advised to schedule an
appointment for this repair.
Required Technician Training
Subaru technicians will be required to take and pass the WRD-23 12-Volt Inverter Connector
Corrosion Video and Post Test before performing the WRD-23 recall service procedure. The video
and post test are currently available on STAR-U.
Technicians must also complete the following required WBT courses in STAR-U, before performing
the WRD-23 recall service procedure. These WBT courses are currently available, and technicians
