Frequently Asked Questions

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

• A steady light indicates a detected fault in emissions, fuel, ignition, or hybrid systems that needs diagnosis but may not be immediately critical.
• The vehicle’s onboard computer stores trouble codes that guide technicians to the root cause—diagnosis is required for safe, effective repair.
• Prompt service at our dealership uses factory tools and genuine parts to correct issues and often costs less than independent shops when you factor in long-term savings.
• Any repair covered under warranty must be completed at a certified dealership to maintain coverage and ensure proper documentation.

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

• Start with simple checks: ensure the gas cap is secure, inspect for obvious fluid leaks, and note changes in performance or sounds.
• Even if symptoms seem minor, schedule a dealership diagnostic so factory-grade scanners can read stored trouble codes accurately.
• Clearing codes without repair hides problems and risks larger failures; our service prioritizes repair-first, then reset to preserve long-term value.
• Warranty-covered concerns must be addressed at a certified dealership to keep coverage valid and ensure genuine-parts repairs.
