Check Engine Light Flashing
The sight of a flashing check engine light in your 2025 Subaru Impreza signals an active misfire or other condition that may cause catalytic converter damage if you continue driving.

Addressing a flashing light quickly saves you from costly downstream repairs and improves safety and drivability.
