It means the engine computer detected a fault and stored an OBD-II trouble code identifying the affected system.

On a 2023 Chevrolet Traverse, causes range from minor EVAP leaks (like a loose fuel cap) to issues that can damage the catalytic converters if ignored. We retrieve the code, review freeze-frame data, and test the related components to find the exact failure. If the light is flashing, avoid driving—this signals a severe misfire.

• Steady light: drive cautiously and schedule service soon
• Flashing light: stop driving and arrange a tow
• Schedule service for a precise diagnosis

Typical causes include O2 sensor faults, EVAP leaks (loose gas cap), MAF sensor issues, misfires, or catalytic converter efficiency codes.

For the 2023 Chevrolet Traverse’s 3.6L V6 (310 hp), even small air-fuel imbalances can trigger a code. Minor items are often inexpensive to fix, but misfires left unchecked can overheat and damage the converters. Our team isolates root causes, then provides a written estimate so you can decide next steps with confidence.

• Inspect the gas cap seal and fit after refueling
• Address misfires promptly to protect catalytic converters
• Book testing: schedule now

Yes if the light is steady; no if it’s flashing—flashing indicates a severe misfire that can damage the catalytic converter.

For a steady light on a 2023 Chevrolet Traverse, reduce load and head to our Murray location for diagnostics. If the light flashes, pull over safely and arrange a tow to prevent costly converter damage. Either way, prompt testing protects performance, emissions compliance, and long-term reliability.

• Steady = drive gently to service; flashing = tow recommended
• Protects 3.6L V6 and emissions components

Our OEM-certified technicians access live data, perform pinpoint tests, and provide a written estimate, helping you avoid guesswork and repeat repairs.

• Factory scan access and proprietary data for Chevrolet systems
• Isolation testing prevents unnecessary parts swapping
• Book a diagnostic or view service specials

You’ll receive a written estimate before any repair so you can approve work with confidence. If additional testing is advisable, we’ll explain the why and the cost before proceeding.
