Frequently Asked Questions

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

• Confirm the gas cap is tight and undamaged; a loose cap is a frequent and simple cause for the warning.
• Look for other dashboard alerts (temperature, oil pressure) that elevate urgency.
• Note recent changes: new fuel, recent repair work, or fluid top-offs that might trigger a code.
• If the light persists, bring your 2016 Hyundai Sonata Plug-in Hybrid to Courtesy Hyundai of Tampa — we perform a complete scan so warranty-covered repairs remain valid when done at a certified dealership.

How long does a check engine light service take?

• Standard diagnostic scans typically take 30–60 minutes to read codes and assess immediate concerns.
• Minor repairs like replacing a gas cap or resetting a sensor can often be completed the same day.
• Complex repairs (fuel system, catalytic converter, or intermittent misfires) may require parts ordering and can take longer; we provide clear time estimates up front.
• Choosing Courtesy Hyundai of Tampa often saves you time and money in the long run — our factory-trained technicians diagnose accurately the first time and reduce repeat visits.

What is the most common reason for check engine light on a 2016 Hyundai Sonata Plug-in Hybrid?

• Faulty or aging oxygen sensors and catalytic efficiency codes are very common and affect emissions and economy.
• Fuel mixture issues (lean/rich) or vacuum leaks can trigger codes and raise fuel consumption.
• Evaporative system leaks (loose gas cap or cracked hose) often cause illuminated engine warnings.
• Regular scans at our dealership reduce long-term costs by finding root causes early, and warranty repairs must be completed at a certified dealership to remain covered.

What does it mean when the check engine light comes on in a 2016 Hyundai Sonata Plug-in Hybrid?

• It indicates the vehicle’s onboard diagnostics detected an emissions or engine control issue and stored a trouble code.
• Codes range from minor (evap leaks) to serious (engine misfires affecting catalytic converters); severity dictates urgency.
• Early diagnosis prevents costly downstream repairs and protects hybrid system efficiency and fuel economy.
• We recommend a factory-level scan at Courtesy Hyundai of Tampa so repairs are performed correctly, preserving warranties and often costing less than independent shops over time.
