Frequently Asked Questions

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

• Look for any dashboard messages or alerts that explain the fault—EV systems often display complementary warnings with the light.
• Confirm charging equipment and cable connection if the vehicle was recently charging; poor connections can trigger a fault.
• Check for reduced performance or limp-home mode; if present, stop driving and contact the dealership for safety guidance.
• Document when and how the light appeared (after charging, while driving, at startup) to help our technicians narrow diagnostics.
• Remember: repairs covered under warranty must be completed at a certified dealership to preserve coverage and ensure proper software updates.

How long does a check engine light service take?

• Initial diagnostic scan typically takes 30–60 minutes to read fault codes and perform basic inspections.
• Simple fixes like sensor replacement or software updates can often be completed the same day.
• More complex EV powertrain or high-voltage system repairs may require parts and additional time—our service advisors provide realistic timelines up front.

What is the most common reason for check engine light on a 2025 Hyundai IONIQ 6?

• For EVs like the 2025 Hyundai IONIQ 6, the most common causes are battery management or charging system faults and software/communication errors between modules.
• Sensor failures—such as coolant, temperature, or CAN-bus communication sensors—can also trigger the light even if they are low-cost items to replace.
• Occasionally a charging plug or external connector issue will present as a check engine light rather than a dedicated charging alert.
• Timely dealership diagnosis prevents small sensor faults from escalating into expensive power electronics or battery repairs; warranty repairs must be done at a certified dealership.
