Problem: Subaru of America, Inc. (Subaru) is recalling certain 2026 Crosstrek Hybrid, 2025-2026 Forester Hybrid, Forester, and 2019-2026 Ascent vehicles. These vehicles were manufactured with an incorrect Gross Axle Weight Rating (GAWR) on the certification label.

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

Fix: 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. Letters informing owners of the safety risk were mailed August 27, 2026. Additional letters will be mailed once the remedy is available. Owners may contact Subaru customer service at 1-844-373-6614.

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