Jul 7, 2026 Safety recallEQUIPMENT:OTHER:LABELSCampaign 26V436000

Reported concern

Subaru of America, Inc. (Subaru) is recalling certain 2026 Crosstrek Hybrid, 2025-2026 Forester Hybrid, Forester, and 2019-2026 Ascent vehicles.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) 110, "Tire selection and rims."

Manufacturer’s stated response

Subaru will mail a new certification label to owners, free of charge. Owners may also choose to have a dealer install the new label, free of charge.

Dec 8, 2022 Safety recallELECTRICAL SYSTEM:WIRING:INTERIOR/UNDER DASHCampaign 22V907000

A park-outside advisory is recorded. Verify applicability immediately with NHTSA or the manufacturer.

Reported concern

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.

Repairs will be performed free of charge. Owner notification letters were mailed August 19, 2022. This recall includes all vehicles previously recalled under 19V-855. Vehicles previously recalled under 19V-855 will need to have the new remedy performed for this recall once available. Owners may contact Subaru customer service at 1-844-373-6614.
