Frequently Asked Questions

What is the most common reason for check engine light on a 2023 Kia EV6?

• Often related to electric powertrain support systems: battery management sensors, 12V system faults, thermal management, or onboard charger issues.
• Software or communications faults (CAN bus/U codes) can trigger the light even if a physical component is fine.
• Ignoring codes can increase repair cost dramatically—small sensor fixes stay inexpensive; high-voltage repairs can be costly.
• Courtesy Kia of Brandon uses Kia-specific tools to pinpoint causes and often saves you money versus independent shops by avoiding unnecessary parts and repeat visits.
• Repairs covered by warranty must be completed at a certified dealership to retain coverage and proper documentation.

What does it mean when the check engine light comes on in a 2023 Kia EV6?

• It indicates the vehicle detected a fault and logged a diagnostic trouble code; on an EV this commonly reflects power electronics, battery management, charging, or 12V subsystem issues.
• A steady light typically means a non-immediate fault; flashing signals potentially severe or damaging conditions.
• The code helps prioritize repair — some problems are quickly resolved with a sensor or software update, others require component repair.
• Bringing your EV6 to Courtesy Kia of Brandon ensures factory-trained technicians read codes with Kia tools and provide accurate repair plans.
• Reminder: warranty-covered repairs must be performed at a certified dealership to maintain protection and avoid out-of-pocket surprises.

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

• Look for immediate on-screen alerts in the instrument cluster or infotainment system describing the fault.
• Confirm charging equipment and connectors are secure and the 12V battery connections are tight if at a charging location.
