Manufacturer Subaru of America, Inc.


Potential Number of Units Affected 8,413



Subaru of America, Inc. (Subaru) is recalling certain 2019-2022 Crosstrek Hybrid vehicles. The harness terminal that supplies low-voltage power from the converter to the 12-Volt battery may corrode and break, preventing the 12-Volt battery from charging.



Dealers will replace the converter terminal mounting bracket. If corrosion is found on the terminals, the 12-Volt output harness and terminals will also be replaced. Repairs will be performed free of charge. Owner notification letters are expected to be mailed April 14, 2023. Owners may contact Subaru’s customer service at 1-844-373-6614. Subaru’s number for this recall is WRD-23.



Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
