The facelifted Ioniq 5 NE1 arrives with a larger 84 kWh battery, up to 570 km WLTP range, and a much-requested rear wiper. Built on the proven 800V E-GMP platform, the RWD version produces 228 hp from a single rear motor and weighs 2,060 kg. Ultra-fast DC charging (10-80% in roughly 18 minutes at up to 263 kW) remains a standout feature. New for the facelift are physical buttons for seat heating and parking assist, the ccNC infotainment system, and improved cabin insulation.

Common Problems
The ICCU can fail, stopping 12V battery charging and causing complete loss of drive power · more· less
The ICCU manages DC-to-DC conversion between the high-voltage battery and the 12V auxiliary system. When it fails, the 12V battery drains and the car shuts down, displaying 'Check Power Supply' or 'Check Electric Vehicle System' warnings. Hyundai has recalled over 145,000 E-GMP vehicles worldwide for this issue. Despite Hyundai claiming the facelift ICCU is improved, forum reports from early 2026 confirm failures on 2025 model year NE1 vehicles, some with under 6,000 km. The failure rate across all E-GMP vehicles is estimated at 2-10% depending on model year. Critically, Hyundai has extended the ICCU warranty to 15 years / 400,000 km, meaning repair should be free for all current used examples. If somehow not covered, out-of-warranty replacement costs approximately €2,500-3,500 including parts and labour. Replacement parts can be backordered 4-8 weeks. Always verify ICCU recall completion and check for stored P1A fault codes before purchasing.
The small 12V battery drains within 1-2 weeks of inactivity, leaving the car unable to start · more· less
This is the most commonly reported complaint across all Ioniq 5 generations. The car's background processes (Bluelink connectivity, alarm system, sensors) drain the 12V battery when parked. Third-party apps that poll the car via Bluelink can accelerate the drain dramatically. Hyundai addressed the worst cases by limiting Bluelink server traffic to 20 transactions per day and blocking problematic apps. A 12V battery replacement costs €150-250. Some owners report needing 2-3 replacements within the first few years. Keeping the main high-voltage battery above 50% enables automatic 12V charging, and using a trickle charger during extended parking prevents the issue. Upgrading from the OEM lead-acid battery to an AGM type can reduce the chance of voltage spikes that damage the ICCU.
The new ccNC infotainment system can freeze, lose features after updates, or fail OTA updates · more· less
The facelift NE1 uses the newer ccNC (Connected Car Navigation Cockpit) infotainment platform, replacing the earlier 5W system. Early reports include screen freezes, loss of intelligent speed limit assist after software updates, and failed over-the-air updates that require dealer intervention. Manual USB updates can be very large (up to 45 GB) and take 6-8 hours to install. In most cases, issues are resolved through dealer software reflashing at no cost. If the head unit hardware fails, replacement costs approximately €300-500 out of warranty. Hyundai has been slow with infotainment update releases compared to competitors.
Persistent rattling from the tailgate area, particularly noticeable in the silent EV cabin · more· less
One of the most commonly reported Ioniq 5 complaints, carried over from the pre-facelift. The noise comes from tailgate bump stops, the latch striker, rear seat belt guide clips, or loose trim in the cargo area. In the near-silent EV cabin, even minor rattles are very noticeable. Hyundai has issued multiple TSBs: 23-BD-006H and 24-BD-012H (October 2024), the latter providing updated larger and softer guide bumpers. Under warranty, the fix is free. DIY solutions include adding adhesive velcro strips to bumper stops or bolt washers to the trunk door hinges. Out of warranty, parts are inexpensive but dealer diagnosis and labour can reach €200-300 if multiple noise sources need addressing.
Charging port overheats at 11 kW AC, throttling charge speed or stopping the session · more· less
A known design limitation across all E-GMP platform cars. The AC charging inlet can overheat when charging at the maximum 48A / 11 kW rate, tripping the temperature sensor. Hyundai TSB 23-EV-003H addresses this with a software update that monitors port temperature and throttles the charging rate. The practical workaround is to reduce the charging current to 32A (approximately 7 kW), which is still sufficient to fully charge overnight. If the connector is physically damaged from overheating, a new charging port assembly costs €300-600. This primarily affects home charging at maximum rate in warm ambient conditions.
Front proximity sensors trigger false collision warnings when stationary in traffic · more· less
Multiple owners report the front parking sensors going off with yellow and red alerts while the car is completely stationary and nothing is nearby. The triggers include exhaust gases from vehicles ahead, interference from other cars' parking sensors, and cold humid conditions. Unlike some competitors (Mercedes-Benz), Hyundai does not disable proximity sensors while the vehicle is stopped. There is no permanent firmware fix yet. Owners can temporarily disable the feature through the driving safety menu. This is an annoyance rather than a mechanical issue and does not require repair, but can be startling and distracting in stop-and-go traffic.
Improved facelift, but ICCU remains the key concern
The facelifted Ioniq 5 NE1 RWD benefits from a larger battery, better interior, and updated software compared to the pre-facelift model. The RWD variant avoids AWD-specific issues like front motor clutch noise and heat pump compressor failure. However, the ICCU failure has been confirmed on 2025 NE1 models, so the problem persists despite Hyundai's claims of improvement. The saving grace is Hyundai's extended ICCU warranty (15 years / 400,000 km), which should cover any failure for the foreseeable future. Beyond the ICCU, most issues are minor: 12V battery drain (manageable), tailgate rattles (TSB available), and infotainment quirks (updatable). Battery degradation data from the pre-facelift Ioniq 5 is encouraging, with a test car retaining 88% capacity after 580,000 km.

The ICCU recall is critical and should be verified before any purchase. Hyundai has issued multiple recall campaigns for this issue across different model years. Even if one recall was completed, a supplemental recall may also apply. Contact Hyundai with the VIN to confirm all recalls have been completed. European recall campaign numbers may differ from US NHTSA numbers.
