2018 Chevrolet Cruze Check Engine Light Codes

At Stevinson Chevrolet in CO, we see the most common check engine light codes for the 2018 Chevrolet Cruze: P0420 (catalyst system efficiency), P0171/P0174 (fuel trim lean conditions), P0300–P0304 (engine misfires), and P0135/P0136 (oxygen sensor/heater circuit). Ignoring these codes risks reduced fuel economy, increased emissions, and progressive damage — for example, a P0420 left unaddressed can allow a failing catalytic converter to overheat, leading to replacement costs far higher than timely repairs. Our factory-trained technicians use Chevrolet-specific diagnostics to map codes to exact causes, then provide transparent repair options that often cost less than independent shops once you factor in correct parts and long-term reliability. We explain the cost implications clearly — immediate savings from accurate repair, and long-term savings due to improved fuel economy and fewer repeat visits. To protect warranties, repairs covered under warranty must be performed at a certified dealership; our team handles those claims directly. Book an appointment quickly using our online scheduler: schedule service, and review current service specials to see how we help you save.

2018 Chevrolet Cruze Check Engine Light Reset

Resetting the check engine light on a 2018 Chevrolet Cruze without fixing the underlying issue can mask dangerous conditions and lead to more expensive repairs later.

Our technicians use Chevrolet factory tools that read pending and stored codes, clear them correctly, and verify repairs with drive-cycle testing.
