Frequently Asked Questions

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

• Check the gas cap for a secure fit and visible damage — a loose or cracked cap is a common trigger and easy to fix.
• Look for obvious signs like low oil, coolant leaks, smoke, or unusual smells; address urgent safety issues first.
• Note whether the light is steady or flashing; a flashing light can indicate an immediate risk and requires stopping driving when safe.
• If the issue isn’t obvious, bring your 2024 GMC Canyon to Coggin Buick/GMC of Orange Park for a professional scan and diagnosis.
• Remember: repairs covered under warranty must be performed at a certified dealership to maintain coverage and ensure proper factory procedures.

How long does a check engine light service take?

• Basic diagnostics with an OBD-II scan typically take 30–90 minutes; more involved inspections or tests may add time.
• Simple repairs (gas cap, sensor swap) can often be completed the same day; complex repairs like catalytic converter or engine work may require additional time.
• Our factory-trained technicians use OEM tools to speed accurate diagnosis and reduce repeat visits, saving you time and money long term.
• We provide clear time estimates before work begins and prioritize warranty-covered repairs at the certified dealership for proper documentation.
