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

• Start with the basics: check that the gas cap is tight and undamaged — a loose cap commonly triggers emissions codes.
• Look for obvious signs: smells of fuel, smoke, fluid leaks, or unusual noises; document what you observe for the technician.
• Check dashboard indicators and recent driving conditions (cold start, towing, low fuel) and note them before service.
• For safety, if the light is flashing, stop driving and have the vehicle towed to our service center to prevent further damage.
• Even for simple issues, certified dealership service protects warranty coverage and provides long-term savings through proper repairs.

How long does a check engine light service take?

• Basic code reading and initial inspection usually take 30–60 minutes, depending on available appointment times and vehicle condition.
• Further diagnostics or road tests can extend the visit to 1–3 hours; complex repairs will require a tailored estimate and scheduling.
• At Coggin Buick/GMC of Orange Park we prioritize efficient service, factory-trained technicians, and clear timelines to minimize downtime.
• Scheduling in advance at /specials/service.htm or by phone speeds the process and helps you plan around immediate and long-term savings.
• If warranty work is involved, repairs must be done at a certified dealership; we’ll explain any additional time needed to meet factory procedures.

What is the most common reason for check engine light on a 2027 Buick Enclave?

• One of the most common causes is a loose or faulty gas cap leading to EVAP system codes and emissions warnings.
• Sensors such as oxygen (O2) sensors and mass air flow (MAF) sensors frequently generate codes as they age or fail.
• Minor misfires, ignition or fuel system issues, and catalytic efficiency problems also rank high among causes.
• Timely diagnosis at our dealership prevents escalation; incomplete repairs at independent shops can increase long-term cost and risk warranty complications.
• For accurate diagnosis and cost-effective repairs, trust Coggin Buick/GMC of Orange Park — factory procedures, OEM parts, and service specials help save money.
