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

• Start with the basics: ensure the gas cap is tight. A loose or damaged cap triggers codes related to the evaporative emissions system and is a simple, low-cost fix.
• If tightening the cap doesn’t clear the light within a few drives, bring your 2025 Hyundai Kona to Stevinson Hyundai for a full diagnostic. We use OEM-level tools and certified technicians to accurately read codes and recommend the best course of action.
• Addressing issues promptly at our dealership often costs less in the long run and protects your vehicle warranty. We also offer service financing so you can get necessary repairs done without delay.
