Frequently Asked Questions

What is the first thing to check when the check engine light comes on?

• Verify the gas cap is tight and undamaged — a loose cap is a common trigger on a 2024 Buick Encore GX.
• Confirm fuel level and fuel quality; low fuel or contaminated gas can set a code.
• Look for obvious issues: a disconnected vacuum line, visible fluid leaks, or damaged wiring near the engine.
• If basic checks don’t clear the light, bring your vehicle to Coggin Buick/GMC of Orange Park for a professional scan and safe diagnosis.
• Remember: repairs covered under warranty must be completed at a certified dealership to preserve coverage.

• Initial diagnostic scan typically takes 30–60 minutes for a 2024 Buick Encore GX to read and interpret codes.

• Complex repairs — such as misfire diagnosis or catalytic converter work — may require parts and follow-up, extending service to one or more days.
• We prioritize clear timelines and use factory-trained technicians to reduce repeat visits, saving you time and money long term.
