Frequently Asked Questions

What is the most common reason for check engine light on a 2024 Kia Niro Plug-In Hybrid?

• Oxygen sensor faults and catalytic converter concerns are frequent causes that affect emissions and efficiency.
• Loose or damaged gas caps often trigger a code and are a simple, low-cost fix—our technicians check this first.
• Ignition components like spark plugs or coils create misfire codes that reduce fuel economy and performance if not addressed.
• Addressing issues promptly at Nalley Kia often costs less than independent shops over time: we combine competitive pricing, factory parts, and warranty protection for greater long-term savings.

What does it mean when the check engine light comes on in a 2024 Kia Niro Plug-In Hybrid?

• The light signals that an emissions or engine-management system has detected an irregularity—ranging from minor (loose fuel cap) to serious (engine misfire).
• A steady light usually means non-critical issues that still need prompt diagnosis to avoid bigger repairs.
• A flashing light indicates an active misfire or condition that can damage the catalytic converter and requires immediate attention.
• For accurate diagnosis and warranty compliance, repairs covered under warranty must be performed at a certified dealership like Nalley Kia.

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

• Verify the gas cap is tight and undamaged—this resolves many emissions codes and is an easy first step.
• Check oil level and visible fluid leaks; low fluids can trigger engine management warnings.
• If the light is flashing, reduce power and have the vehicle inspected immediately to prevent catalytic converter damage.
• When in doubt, book a fast diagnostic with Nalley Kia so factory-trained technicians can assess codes and recommend the most cost-effective repairs.
