Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| ICCU failure: 12V battery charging unit defective The Integrated Charging Control Unit (ICCU) can fail and no longer charge the 12V battery. Power loss while driving follows. Several recall actions known; ICCU replacement often takes weeks due to supply shortages. Symptoms: 'Limited Power' warning; fault code P1A9096; sudden loss of drive; 12V systems fail from 40,000 km | High | |
| DC fast charging: loose HV cable connector or charging fault A loose screw connection on the HV cable connector near the CCS port can completely disable DC fast charging. In winter charging power drops to 45–55 kW instead of 220 kW. Symptoms: Charging station shows error; no DC charging possible; charging session stops unexpectedly; significantly reduced charging speed from 30,000 km | Medium | |
| ICCU defect drains 12V battery and immobilises vehicle The Integrated Charging Control Unit (ICCU) overcharges the 12-volt battery with up to 14.7V and permanently damages it. When the ICCU fails the vehicle cannot be started; Hyundai has initiated multiple worldwide recalls. Symptoms: 12V battery flat despite charged high-voltage battery, vehicle cannot be activated, ICCU fault message from 20,000 km | High | |
| Infotainment system freezes or responds slowly The large 12-inch display on the Ioniq 5 occasionally freezes or responds slowly. Software updates bring some improvement; the issue is widely known. Symptoms: Touchscreen unresponsive, OTA update fails, system reboots from 20,000 km | Low | |
| 230V socket — system error Connecting devices to the Ioniq 5's 230V interior socket triggers the 'Check BEV electrical system' error. The cause lies in the V2L unit control logic; a software update resolves the issue. Symptoms: Error message when using 230V socket, V2L deactivated, warning on display from 5,000 km | Low |
