Frequently Asked Questions

What is the most common reason for check engine light on a 2023 Hyundai Santa Fe Plug-In Hybrid?

• Loose or faulty gas cap causing an evaporative emissions (EVAP) leak — a simple fix that often clears the light quickly.
• Faulty oxygen sensor or catalytic converter issues that affect emissions and fuel economy if left unaddressed.
• Engine misfires from ignition or fuel delivery faults; in a plug-in hybrid this can also relate to hybrid system charge or control sensors.
• EV components or battery charging sensors specific to plug-in hybrids may trigger codes requiring trained hybrid technicians.
• Our trained technicians at Courtesy Hyundai of Tampa diagnose the root cause and recommend cost-effective repairs that often save you more than independent shops over time.

What does it mean when the check engine light comes on in a 2023 Hyundai Santa Fe Plug-In Hybrid?

• It signals the vehicle’s onboard computer has detected an emissions, ignition, fuel, or hybrid system irregularity.
• Codes range from minor (evap leak, sensor drift) to serious (misfires, catalytic converter or high-voltage system faults).
• Immediate diagnosis prevents escalation; untreated faults can reduce fuel efficiency, electric range, and lead to costly repairs.
• Certified dealership service ensures accurate hybrid-safe handling, OEM parts, and warranty compliance when repairs are needed.
• Courtesy Hyundai of Tampa provides fast diagnostics and transparent estimates, often costing less overall than independent shops because we focus on right-first-time repairs and long-term savings.

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, easily fixed trigger for the light.
• Note any drivability symptoms (stalling, rough idle, reduced EV range, or power loss) and avoid heavy loads if present.
• Confirm whether the light is steady or flashing — a flashing light requires immediate attention and likely towing.
• Bring your 2023 Hyundai Santa Fe Plug-In Hybrid to our service team so we can read codes with OEM-grade scanners and protect hybrid components.
• Remember: warranty-covered repairs must be done at a certified dealership to preserve coverage and ensure proper hybrid system care.

How much does a check engine light diagnostic cost for a 2023 Hyundai Santa Fe Plug-In Hybrid?

• Diagnostics fees vary; at our dealership typical scan and inspection fees are competitive and often lower in total cost than independent shops when you factor in accurate diagnosis and OEM parts recommendations.
• Minor fixes (gas cap, small sensor) can be inexpensive; component replacements (oxygen sensor, EVAP parts) have predictable, transparent pricing.
• Serious hybrid or catalytic converter repairs are pricier but avoiding delay prevents far greater long-term expenses.
• Warranty repairs must be performed at a certified dealership to keep coverage valid; we’ll check eligibility and apply warranty where appropriate.
• We provide clear estimates before work begins and emphasize immediate and long-term savings by using factory-trained technicians and genuine Hyundai parts.

How long does a check engine light service take?

• Basic code read and inspection typically take 30–60 minutes; this identifies next steps and provides a reliable estimate.
• Minor repairs (gas cap, sensor swap) can often be completed the same day; more complex repairs or hybrid system work may require additional diagnostic time.
• If parts are required, timing depends on availability; Courtesy Hyundai of Tampa stocks common components to reduce wait times.
• Warranty-covered work must be done by certified technicians; performing repair at our dealership ensures proper documentation and faster resolution of warranty claims.
• We prioritize accurate diagnosis and safe hybrid handling to save you time and money over the life of your vehicle.
