Frequently Asked Questions

What is the most common reason for check engine light on a 2026 Kia EV6?

• Common causes include battery management system alerts, charging system faults, inverter or motor controller errors, and sensor or communication issues with the high-voltage system.
• Software or firmware messages are frequent on modern EVs and often require dealer-level diagnostic tools to read and update control modules.
• Ignoring these warnings can reduce range, degrade battery health, or lead to more costly repairs later — immediate dealer diagnostics can prevent escalation.
• Nalley Kia’s factory-trained technicians diagnose EV-specific systems quickly; for warranty eligibility, any covered repair must be completed at a certified dealership.

What does it mean when the check engine light comes on in a 2026 Kia EV6?

• A check engine or malfunction indicator light on an EV can mean a wide range of issues from minor sensor faults to serious high-voltage system alerts involving the battery, inverter, or charger.
• The dashboard may also show companion messages (charging disabled, reduced power) that help prioritize service urgency.
• Our technicians use Kia-approved diagnostic software to interpret EV-specific codes and recommend repair actions that protect performance and range.
• When a repair falls under warranty, it must be performed at a certified dealership to maintain coverage — Nalley Kia handles those repairs and any related paperwork.

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

• For an EV, start with obvious items: confirm the vehicle is fully stopped and check the instrument cluster for any detailed warnings or charging messages.
• Verify the charging cable and port if you were charging, and look for visible signs of smoke, unusual smells, or fluid leaks — do not drive if you detect these.
• Power-cycle the vehicle (turn off for a few minutes then restart) to see if a transient fault clears; if the light persists, schedule dealer diagnostics.
• Nalley Kia’s service center is equipped to perform a safe, fast inspection; dealership service often costs less than independent shops while delivering factory-trained care and preserving warranty coverage.
