2024 Chevrolet Express Check Engine Light Codes

At Stevinson Chevrolet in CO we frequently see codes on the 2024 Chevrolet Express such as P0171 (system too lean), P0420 (catalyst efficiency), P0300 (random/multiple misfires), P0455 (large EVAP leak), and P0128 (coolant thermostat). Ignoring these codes can quickly escalate costs—an unresolved P0171 can reduce fuel economy and cause increased wear; a P0420 left alone often leads to catalytic converter failure that can cost thousands; misfires (P0300) can damage pistons and the catalytic converter and create unsafe driving conditions. Our factory-trained technicians diagnose the exact cause and present a clear estimate so you make informed decisions. Choosing Stevinson Chevrolet means access to OEM parts, certified techs, and a service lane designed for speed and comfort. We provide digital inspections, clear pricing, and options to minimize long-term ownership costs.
