ELECTRICAL SYSTEM:WIRING:INTERIOR/UNDER DASH

Summary: Subaru of America, Inc. (Subaru) is recalling certain 2019-2022 Ascent vehicles.

Safety Consequence: A melting ground terminal increases the risk of a fire.
Manufacturer Remedy: Owners are advised to park their vehicle away from structures and to avoid leaving the vehicle unattended while the engine is running. An owner who notices or smells smoke coming from the dash or driver's footwell area should immediately stop operating the vehicle and turn the ignition switch to the "Off" position. Dealers will replace the PTC heater ground bolts and if necessary, replace the ground wire and the connector holder, free of charge. Owner notification letters are expected to be mailed February 6, 2023. Owners may contact Subaru's customer service at 1-844-373-6614. Subaru's number for this recall is WRL-22.
