• Common causes include 12V auxiliary battery issues, charging/charging-circuit faults, thermal management alerts, and inverter/electric-drive faults. Early diagnostics can prevent escalation to costly battery or inverter replacements.
• Stevinson Hyundai’s certified technicians use Hyundai OEM diagnostics to identify whether an issue is a simple fix (like a 12V battery replacement) or needs deeper attention, helping you avoid larger expenses later.

Check Engine Light Reset

Resetting the check engine light on a 2025 Hyundai IONIQ 5 is more than clearing a code; it’s about confirming the underlying fault no longer exists. At Stevinson Hyundai in Colorado, our process begins with a complete diagnostic scan to record codes, freeze-frame data, and live sensor readings.

This prevents repeated visits and ensures long-term reliability. Doing this work at our dealership means you receive transparent OEM pricing, genuine Hyundai parts, and certified technician workmanship—factors that deliver immediate savings by avoiding repeat failures and long-term savings through preserved vehicle health and warranty protection. If a repair is warranty-covered, it must be completed at a certified dealership to keep coverage valid; our service team handles that process for you. We also offer service financing to make prompt, quality repairs affordable. To get started, schedule service or check current service specials for added value.
