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

Consequence: An incorrect GAWR label may lead to an overloaded vehicle, increasing the risk of a crash.
Remedy: 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.

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