Hyundai Ioniq 5 NE-FL(NE)
Weaknesses, engine ratings and buying advice
The 2024 facelift fixes most pre-FL issues. Battery: 77.4 → 84 kWh (large), 58 → 63 kWh (small) — range up to 495 km WLTP. Finally a rear wiper and physical shortcut buttons. Wireless CarPlay. The 11 kW AC charger remains unchanged.
Test-drive checklist: Same as pre-FL. FL units have the rear wiper.
2026 market: New from around $43,000–$56,000. Used stock thin, mostly above $42,000.
Insider pick: Pre-FL with a discount beats the FL on value unless the rear wiper is a dealbreaker.

Engine Overview
The Hyundai Ioniq 5 NE-FL is available with one engine variant at 135 hp.
E-GMP electric motor — Hyundai's 800V platform for Ioniq 5, Ioniq 6 and EV6. ICCU (Integrated Charging Control Unit) is the biggest risk: recall for failure, charge loss and 12V system shutdown. 12V battery drains from Bluelink telematics and charge port idle current — most common daily issue. Software bugs in drive strategy known. A technologically leading drivetrain with 800V fast charging when ICCU works and software is current.
- !! Recall: ICCU control unit failure (charging loss) from 30,000 km
The Integrated Charging Control Unit (ICCU) can be damaged by electrical overload and no longer charge the 12V battery. The vehicle progressively loses all electrical functions while driving.
Symptoms: Dashboard warnings and beeping, progressive power loss, vehicle enters emergency mode, 12V battery not charging. - !! Driveshaft breakage (recall) from 30,000 km
Defective heat treatment by a supplier led to driveshafts on the Ioniq 5 and 6 (production 2021–2023) that could break. Recall 41D022 affected 155,760 vehicles worldwide, including 46,604 in Germany.
Symptoms: Sudden loss of drive, noises from drivetrain, vehicle coasts to a stop - !! 12V battery discharge (Bluelink/charging flap) from 20,000 km
Third-party Bluelink apps can trigger up to 5,000 server requests per day, constantly waking the vehicle. The 12V battery drains within hours. Hyundai has limited server traffic to 20 requests per day.
Symptoms: Vehicle completely dead after a short standstill, no remote unlocking, no start, jump-start required.

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 |
