We pair rapid diagnostics with clear estimates and recommended next steps, so you understand the immediate costs and long-term savings of timely repair.

2025 Chevrolet Express Check Engine Light Codes

Common check engine codes for a 2025 Chevrolet Express include P0300 (random/multiple misfires), P0420 (catalyst system efficiency), P0171/P0174 (system too lean), and oxygen sensor codes such as P0135. Ignoring P0300 can lead to poor fuel economy, rough running, and damage to the catalytic converter — increasing repair costs from a simple tune-up to thousands in exhaust system replacement. A P0420 left unfixed may mean reduced emissions performance and failed state inspections, while lean codes can point to vacuum or fuel-delivery issues that reduce engine life. At Stevinson Chevrolet in CO, we diagnose these codes with OEM-grade scanners and follow GM service procedures to deliver accurate repairs that extend the life of your 2025 Chevrolet Express. Our certified technicians, honest estimates, and service financing options help you manage immediate costs and protect long-term vehicle value.
