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

The risk
An incorrect GAWR label may lead to an overloaded vehicle, increasing the risk of a crash.
The 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. Letters informing owners of the safety risk are expected to be mailed August 25, 2026. Additional letters will be mailed once the remedy is available.

The defect
Subaru of America, Inc. (Subaru) is recalling certain 2019-2022 Ascent vehicles. The ground bolt that secures the ground terminal of the Positive Temperature Coefficient (PTC) heater may have been improperly fastened, which could result in melting of the ground terminal and surrounding components.

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.

On May 14, 2026, while driving a 2021 Subaru Ascent (approx. 94,291 miles) on a Texas expressway at highway speed during rush hour, I experienced a sudden and significant loss of engine power.

Fortunately, we were able to safely maneuver the vehicle out of traffic and avoid a collision. Prior to this incident, the vehicle had undergone regular maintenance, and there were no indications of any imminent powertrain failure. While a routine fluid service had been recommended, it

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
