At Mike Shaw Subaru in Denver, Colorado, we see a predictable set of check engine light codes on the 2026 Subaru Crosstrek: P0420 (catalyst efficiency low), P0171/P0174 (fuel trim lean), P0130–P0167 (oxygen sensor faults), and occasional misfire codes like P0300–P0304. Each code carries costs if ignored: a failing catalytic converter can lead to complete exhaust failure and costly replacement; unresolved lean conditions raise fuel consumption and accelerate engine wear; and sensor issues can degrade emissions compliance and performance. Our factory-trained technicians use Subaru-specific scan tools to interpret codes correctly, pinpoint root causes, and provide clear repair estimates. Choosing Mike Shaw Subaru often delivers immediate savings via accurate diagnostics—avoiding unnecessary parts—and long-term savings through OEM parts and proper repairs that preserve fuel economy and resale value.
