Frequently Asked Questions

What is the most common reason for check engine light on a 2026 Hyundai NEXO?

• Sensors and emissions components (oxygen sensors, EVAP leaks) are frequent triggers; these affect drivability and emissions compliance.
• Minor issues left unaddressed can escalate into more expensive repairs like catalytic converter or fuel system damage.
• At Coggin Deland Hyundai our factory-trained technicians diagnose hydrogen-powered systems and conventional OBD-II codes to pinpoint causes quickly.
• Handling repairs at our certified dealership preserves warranty coverage and often costs less over time than piecemeal fixes at independents due to accurate diagnosis and genuine parts.

• Diagnostic fees vary, but most dealerships charge a transparent diagnostic service to read and interpret OBD-II codes; typical ranges fall between modest, fixed fees.
• Coggin Deland Hyundai emphasizes clear estimates, and doing diagnostics and repairs with us often results in immediate and long-term savings versus repeat independent attempts.

What does it mean when the check engine light comes on in a 2026 Hyundai NEXO?

• It indicates the vehicle’s onboard diagnostics detected a fault in emissions, powertrain, or related systems; for the NEXO this can include fuel cell or electrical subsystem alerts as well as standard OBD-II codes.
• Light on steady: a condition that needs timely inspection; light flashing: more urgent risk of damage or unsafe operation.
• Prompt diagnostics at Coggin Deland Hyundai minimize risk and cost—factory-trained technicians use OEM tools to ensure accurate diagnosis.
