Check Engine Light Flashing

A flashing check engine light on a 2018 Chevrolet Traverse signals an urgent condition — typically an active engine misfire that can overheat and damage the catalytic converter, increase emissions, and reduce drivability. When you see a flashing light, it’s important not to ignore it: continuing to drive can turn a relatively straightforward repair (such as replacing a spark plug, ignition coil, or fuel injector) into a costly repair that may exceed $1,000 if the catalytic converter or engine components are compromised. At Stevinson Chevrolet in Colorado, our factory-trained technicians are experienced with the 3.6L V6 in the 2018 Chevrolet Traverse and prioritize rapid, accurate diagnostics to limit downtime and expense. We stock many OEM parts used frequently on Traverses and provide transparent estimates so you understand immediate costs and long-term benefits. We also promote savings through regular service specials, and we offer service financing so you can address urgent repairs today and pay over time. If the check engine light is flashing, contact us immediately or schedule service online to protect your vehicle and avoid larger bills down the road.

2018 Chevrolet Traverse Check Engine Light Reset

Resetting the check engine light on a 2018 Chevrolet Traverse can be as simple as clearing an evaporative emissions code caused by a loose gas cap — but a cleared light does not fix the underlying issue. At Stevinson Chevrolet, we recommend a complete diagnostic rather than an immediate reset because unresolved faults can return and cause progressive damage. Our certified technicians use OEM-level scanning tools tied to Chevrolet service information, ensuring that codes are interpreted correctly and that any required repairs are performed with genuine parts that preserve vehicle longevity and warranty coverage. Choosing dealer service provides transparency: you receive a detailed inspection report, a clear price estimate, and an explanation of how the repair protects long-term value — often delivering lower total ownership cost over time than repeated independent repairs. We make it easy to act by offering financing options for service and consistent service specials to lower your out-of-pocket expense. Ready to address the root cause instead of masking the symptom? Schedule appointment with Stevinson Chevrolet today and get a trusted reset and repair backed by factory training and warranty protection.

2018 Chevrolet Traverse Check Engine Light Codes

The most common check engine light codes for a 2018 Chevrolet Traverse often include P0171/P0174 (fuel trim issues), P0300 (random/multiple cylinder misfire), P0420 (catalyst system efficiency below threshold), and P0455 (large EVAP leak). Each code points to different risks and potential costs: untreated fuel trim or misfire issues lower fuel economy and can lead to engine damage or a failed catalytic converter (which can be an expensive replacement), while unresolved EVAP leaks increase emissions and may prevent your vehicle from passing inspections. At Stevinson Chevrolet in Colorado, we diagnose these codes with Chevrolet-specific scanners that reveal freeze-frame data and cylinder-specific misfire counts, enabling precise repairs and preventing unnecessary parts replacement. Our approach focuses on minimizing total cost of ownership: early detection, OEM parts, and skilled technicians reduce the chance of repeat issues and costly downstream repairs. We also encourage customers to check our service specials and ask about service financing to make recommended repairs affordable.
