2024 Chevrolet Silverado 2500HD Check Engine Light Codes
At Stevinson Chevrolet in Colorado, we see the same common diagnostic trouble codes on the 2024 Chevrolet Silverado 2500HD: P0300 (random/multiple misfires), P0420 (catalyst system efficiency low), P0171/P0174 (system too lean), P0455 (evaporative system large leak), and P0128 (coolant thermostat). Ignoring these codes can escalate costs quickly — a resolved O2 sensor is typically a modest parts-and-labor job, while leaving a P0420 unchecked can mean costly catalytic converter replacement and additional emissions failures. Misfires left unchecked can damage pistons and the catalytic converter and lead to expensive engine work down the road. Our factory-trained technicians use OEM diagnostics and parts to diagnose the exact cause and present transparent estimates that emphasize immediate savings and long-term value. We also highlight service financing to help you address urgent repairs now and pay later, plus ongoing service specials to reduce costs.

2024 Chevrolet Silverado 2500HD Check Engine Light Reset
Resetting a check engine light without addressing the underlying fault is only a temporary fix and can mask issues that lead to larger repairs. At Stevinson Chevrolet, we recommend a full diagnostic and targeted repair before any reset. Our technicians reset codes only after repairs are completed and verified, ensuring the problem won’t reoccur and your vehicle remains covered by any applicable warranties — note that warranty repairs must be performed at a certified dealership. Using OEM parts and manufacturer procedures protects engine performance and longevity and reduces the chance of repeat visits. We provide clear documentation of repairs, labor, and parts used, so you know the exact work done and the long-term benefits: improved fuel economy, consistent performance, and reduced risk of catalytic or engine damage.
