What is the most common reason for check engine light on a 2025 Subaru Legacy?
Common causes include loose or failing gas caps, oxygen sensor issues, or catalytic converter and EVAP problems; each generates a specific code we diagnose quickly.

What is the first thing to check when the check engine light comes on?
Start with simple checks: secure the gas cap and note vehicle behavior (stumbles, reduced power, flashing light) before driving to the shop. If the light is steady, schedule a diagnostic; if it’s flashing, minimize driving and contact us immediately (see our guidance below).

Check Engine Light Flashing
The check engine light flashing on a 2025 Subaru Legacy indicates a severe misfire or condition that can damage the catalytic converter or other components if you continue driving.

At Mike Shaw Subaru in Colorado we recommend stopping in a safe place and contacting our service department immediately; our certified Subaru technicians will prioritize a diagnostic to limit damage and expense. We keep many OEM parts in stock and use factory procedures that deliver reliable repairs and help avoid repeat visits. We also highlight available service specials and can discuss service financing so you can get necessary work done now and spread the cost over time.
