What does it mean when the check engine light comes on in a 2024 Hyundai IONIQ 5?

The light signals a detected fault in the vehicle’s systems—on an EV that can include battery management, charging, inverter, or auxiliary systems.
It can be a minor sensor or software notification, or a sign of a more serious electrical or powertrain issue requiring immediate attention.
Our technicians connect Hyundai-grade scanners to read fault codes and recommend the proper repair to avoid further damage.
Repairs covered by warranty should be completed at a certified dealership to ensure correct procedures and continued coverage.

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

Verify the charging cable and port connection—loose or interrupted charging sessions can trigger faults on an EV.
Check for visible alerts on the instrument cluster and any messages in the vehicle’s infotainment system.
Confirm the 12V auxiliary battery condition; a weak 12V can cause false warnings and erratic electronics behavior.
If any warning persists, bring the vehicle to Nalley Hyundai so we can run a full diagnostic and preserve your warranty coverage.

How long does a check engine light service take?

Diagnostics typically take 30–90 minutes to read codes and run initial tests; some intermittent faults may require longer monitoring.
Minor fixes—software updates or sensor replacements—can often be completed the same day.
More complex repairs involving high-voltage components or parts ordering may take longer; we provide clear timelines and status updates.
Choosing Nalley Hyundai delivers faster, accurate service and avoids repeat repairs, offering both immediate and long-term savings.

2024 Hyundai IONIQ 5 Check Engine Light Reset

Resetting a check engine light on a 2024 Hyundai IONIQ 5 is possible with an OBD-II or manufacturer-level scan tool, but a reset only clears codes—it does not fix root causes. At Nalley Hyundai we recommend having the vehicle diagnosed and serviced before any reset. Our factory-grade tools read pending and permanent codes, capture freeze-frame data, and apply official software updates when needed. Dealer service protects warranty coverage because warranty repairs must be performed at a certified dealership. Relying on an independent reset may mask a developing fault and increase long-term repair costs; our approach prioritizes correct repairs, documented service history, and lower lifetime ownership expenses.

2024 Hyundai IONIQ 5 Check Engine Light Codes

Common codes for a 2024 Hyundai IONIQ 5 often point to battery management, charging system, inverter, or sensor faults. Minor software or sensor codes can cost under $200 to diagnose and repair, while faults involving the inverter, onboard charger, or high-voltage battery modules can range from several hundred to several thousand dollars if left unchecked. Ignoring codes risks progressive damage: a small sensor issue may lead to thermal management strain, reduced range, or complete charging failure. Early dealer diagnosis prevents escalation, preserves warranty coverage, and typically yields lower total ownership costs than delayed or incorrect repairs from non-certified providers.

2024 Hyundai IONIQ 5 Check Engine Light Flashing

A flashing check engine light on a 2024 Hyundai IONIQ 5 indicates an active, potentially severe fault that needs immediate attention. In EVs this can signal serious powertrain or battery issues, thermal events, or faults that affect drivability and safety. Continued driving may cause further damage or trigger limp mode; towing could be required to protect the vehicle and occupants. Bring the vehicle to Nalley Hyundai right away—our team uses Hyundai-specific diagnostics and safety procedures to isolate high-voltage concerns, recommend secure next steps, and complete warranty-covered repairs when applicable. Rapid dealer attention minimizes repair scope and long-term costs.
