BACKGROUND
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.

February 7,2023 – Based on a trend analysis of warranty data, the occurrence frequency is expected to significantly increase over the next five years, and out of an abundance of caution, Subaru decided to conduct a voluntary safety recall. Based on best engineering judgement, Subaru is aware of 9 technical reports (occurring March 2021 – November 2021) and 99 warranty claims (reviewed from Start of Production through January 2023) in the U.S. market. Subaru is not aware of any crashes or injuries resulting from this condition.
Description of Remedy :
Description of Remedy Program : For all affected vehicles, Subaru dealers 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.
Subaru will provide reimbursement to owners for repairs according to the general plan submitted in May 2022.
How Remedy Component Differs from Recalled Component :
Identify How/When Recall Condition was Corrected in Production :
An improved bracket is manufactured with an insulating coating and a protective cap is added to the terminal to mitigate exposure to road salt.
The recall condition was corrected in production on April 6, 2022. Recall Schedule :
Description of Recall Schedule : Dealer notification occurred on February 15, 2023. An interim owner
notification is scheduled to begin before April 14, 2023. Final owner notification will occur once Subaru has provided all retailers with the necessary training and tools, which is estimated before July 2023.
