2023 Hyundai IONIQ 5 Check Engine Light Flashing

A flashing check engine light on a 2023 Hyundai IONIQ 5 signals an active, potentially damaging condition that requires immediate attention. For EVs this can indicate severe motor/inverter issues, critical battery management faults, or charging system failures that could threaten drivability or cause further component damage. If you see a flashing light, avoid continued driving and arrange a tow or immediate inspection—delaying service risks higher repair costs and increased downtime. Our dealership offers rapid triage by factory-trained technicians who can diagnose electrical and powertrain faults accurately. Because warranty repairs must be performed at a certified dealership, bringing your vehicle to Courtesy Hyundai of Tampa preserves coverage and delivers better long-term savings compared with repeated, incorrect repairs.

2023 Hyundai IONIQ 5 Check Engine Light Codes

Common check engine light codes on a 2023 Hyundai IONIQ 5 often relate to battery management (state-of-charge, temperature sensors), inverter/drive unit faults, charging system errors, and inter-module communication issues.
