Frequently Asked Questions

How long does a check engine light service take?

• Initial diagnostic: typically 30–90 minutes using OEM scan tools and live-data analysis to read codes and pinpoint issues.
• Simple fixes (gas cap, loose connector, sensor reset): often completed within the same visit, under two hours.
• Complex repairs (fuel system, catalytic converter, engine mechanical): can require parts ordering and 1–2 days depending on availability.
• We recommend scheduling service at Nalley Hyundai so factory-trained technicians can diagnose quickly and keep you informed of time and cost.

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

• Check the gas cap: a loose or damaged cap is a common, quick fix and can trigger an emissions-related code.
• Observe engine behavior: if the vehicle runs normally, it may be a minor emissions sensor; if rough or stalling, do not drive far.
• For flashing lights, stop driving and contact Nalley Hyundai immediately — a flashing light often signals a severe misfire or catalytic risk.
• Remember: warranty-covered repairs must be performed at a certified dealership to protect coverage and long-term value.
