Frequently Asked Questions

What is the most common reason for check engine light on a 2020 Hyundai Ioniq Plug-In Hybrid?

• Oxygen sensor or catalytic converter inefficiency, which affects emissions and fuel economy.
• Engine misfires from spark plugs or ignition coils—common with higher mileage or deferred maintenance.
• Hybrid-specific faults such as battery charging or inverter issues that require high-voltage diagnostic tools.
• Loose gas cap or evaporative emissions leaks; simple to fix but important to diagnose correctly.
• Prompt diagnosis at our dealership often avoids larger repairs; early fixes save money and preserve performance.

What does it mean when the check engine light comes on in a 2020 Hyundai Ioniq Plug-In Hybrid?

• It signals the vehicle’s onboard computer has detected an emissions or powertrain issue—ranging from minor to urgent.
• A steady light usually indicates a problem that should be diagnosed soon to avoid worsened performance or efficiency.
• A flashing light indicates a severe condition that can damage the catalytic converter or drivetrain—stop driving and seek service.
• Because hybrids combine ICE and electrical systems, our dealership uses OEM-grade scanners and safety protocols for accurate diagnosis.

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

• Confirm whether the light is steady or flashing; flashing suggests a serious misfire and immediate attention is needed.
• Check the gas cap for tightness—an easy fix that can clear an EVAP system code after a few drive cycles.
• Note any drivability symptoms (reduced power, rough idle, stalling) and report them to our service team for faster diagnosis.
• Bring the vehicle to Courtesy Hyundai of Tampa for a professional scan—our hybrid-trained techs protect your warranty and battery systems.
