The failure pattern owners describe
The 2022 Ioniq 5 electrical system is plagued by catastrophic failures tied mainly to the ICCU. Owners describe sudden pops followed by loss of motive power on highways, forcing vehicles into 12–25 mph limp-mode before shutdown. Power loss happens with almost no warning—one driver was forced to swerve across traffic lanes at 60+ mph. Complete electrical failure leaves the vehicle unresponsive to button inputs and unable to shift to neutral without external battery assistance, creating towing hazards.
The ICCU failure prevents the main EV battery from charging the 12V battery, causing secondary start failures. Owners report replacing 12V batteries two or three times within four years—well before normal life expectancy. AC Level 2 charging at home simply fails on many units, displaying "Charging Unsuccessful" or stopping mid-session, while DC fast charging still works (at premium cost). Some vehicles charge at only half their advertised 48-amp rate, throttling permanently to 24 amps after a thermal event.
Hyundai's recall repairs (Campaign 272) apply software updates or fuse replacement, yet failures continue—some occurring within days of the recall. Owners report anecdotal evidence that ICCU failure rates may increase after recall work. Parts shortages are severe; repair wait times span 1–6+ months, with some vehicles awaiting parts since late 2025 with no ETA. One owner made $2,569 in payments on a vehicle never driven. Dealership diagnostics are often inconclusive, and Hyundai corporate responses lag or offer no timeline.

Failure modes owners describe
ICCU (Integrated Charging Control Unit) failure with power loss
The ICCU fails suddenly, often accompanied by an audible pop sound. Vehicle loses motive power, limp-mode restricts speed to 12–25 mph, then complete power loss. The 12V battery is not recharged by the main EV battery after ICCU failure, leaving the vehicle immobile. Failures occur even after software updates and recalls (Campaign 272/24V868000) have been performed.
When: Various mileages and timeframes; one case at 13 months/8,090 miles; another at 24,700 miles/16 months; reports span 2022–2026. Some failures within days or weeks of recall repair.
Symptoms owners cite: Audible pop or thump from vehicle; Orange 'Check Electric Vehicle System' warning (more severe than expected); Red 'Stop Vehicle and Check Power Supply' warning with loud beeping; Sudden loss of motive power; Limp-mode speed reduction to 12–25 mph; Complete vehicle shutdown, unresponsive to input (bricked); Instrument panel goes blank or erratic; Unable to lock/unlock doors, open trunk, use key fob after power loss; 12V battery not recharged post-failure
Codes mentioned: P1A9096, P1A90(96) [0x1A9096]
Repairs/costs cited: ICCU replacement required; high-voltage fuse often blown. Parts frequently on back order; repair wait times 1–6+ months. Replacement ICCU sometimes appears to be same part number as failed unit. Some owners report second ICCU failure after replacement.
Recalls/TSBs owners mention: Recall Campaign 272 (NHTSA 24V868000) and Campaign 997: software update and/or fuse inspection/replacement. Hyundai stated 1% failure rate, but owners report higher actual rates and anecdotal evidence suggests failure rate may increase after recall repair. Hyundai has acknowledged the issue but delays parts distribution; no comprehensive hardware redesign known.
12V battery rapid discharge and starting failures
The 12V battery drains rapidly without clear cause, even when main EV battery is fully charged. Vehicle fails to start or requires extended waiting for main battery to recharge the 12V. Issue recurs despite software updates. Appears linked to ICCU malfunction preventing proper 12V charging circuit management.
When: Multiple instances over months or years of ownership; first occurrence sometimes early in ownership; reoccurrences reported after recall repairs or ICCU replacement.
Symptoms owners cite: 12V battery warning light illuminated; Vehicle fails to start; 12V battery discharged while parked, even after driving; Slow or failed startup requiring external jump or long wait for main battery to recharge 12V; Need to use portable charger or jumper cables; Occasional loss of power while driving (engine/EV system cuts out); 12V battery failing prematurely despite replacement
Codes mentioned: 12V battery low messages
Repairs/costs cited: 12V battery replacement; owners report second and third replacements within 4 years. Some dealers initially deny warranty coverage. Root cause (ICCU-related charging circuit defect) not always identified by dealerships.
Recalls/TSBs owners mention: Recall software updates (Campaign 272, Campaign 204); warranty coverage of 12V battery replacement. Hyundai has not proactively replaced deteriorated 12V batteries caused by ICCU malfunction; owners must request after failure occurs.
AC Level 2 charging derating and thermal throttling
Vehicle advertises 48-amp Level 2 AC charging capability but can only charge at half that rate (24 amps) or less. Charging rate throttles when charge port reaches ~100°C. Issue is well-documented in owner forums and appears to be a hardware defect, not environmental. Hyundai has issued a TSB that automatically derates the charging speed rather than fixing the underlying problem.
When: Typically after 6–12 months of ownership; first noticed when ambient temperature exceeds ~70°F; issue persists through seasonal changes.
Symptoms owners cite: Charging unsuccessful after ~10–15 minutes at maximum charge rate (48 amps); Can only charge continuously at reduced rate (24–32 amps) or minimum rate (5.7 kWh); Progressive degradation (rate decreases over time or with repeated attempts); Charge port thermal issues (~100°C threshold); No customer-facing error codes displayed; Vehicle cannot achieve advertised full charge overnight at home; Insufficient charging rate for long-distance travel buffer
Codes mentioned: No codes displayed to owner
Repairs/costs cited: TSB applied (automatic software derating); provides ~15 minutes of higher power before throttling back down. Does not restore full 48-amp capability. Multiple repairs attempted on some vehicles without resolution. Underlying hardware (likely onboard charger/inverter thermal management) likely defective.
Recalls/TSBs owners mention: TSB issued; Hyundai stated owners should 're-adjust expectations' and accept reduced charging speed. No hardware replacement or full fix offered. Some owners report similar issue persists in vehicles purchased later (July 2023), though at different amp thresholds (32 amps vs. 24 amps).
AC charging failures (Level 1, Level 2, Level 3)
Vehicle fails to charge on AC Level 1 or Level 2 chargers, displaying 'Charging Unsuccessful' message or stopping mid-charge. Some vehicles can still DC fast-charge. Issue appears in onboard charger (OBC), ICCU, or charge port/inlet. Multiple chargers and EVSEs tested; failure persists across different charging locations.
When: Various times; one case at ~83,000 miles; another at 2,000 miles after purchase; some shortly after recall completion.
Symptoms owners cite: Charging fails to initiate on Level 1 or Level 2 chargers; Charging stops shortly after starting; Charging unsuccessful message displayed; Red lights on ChargePoint or similar networked chargers; F2 fault code on home charger; DC fast charging (Level 3) works normally (at 6× higher cost); Vehicle will not charge to full capacity; Multiple independent chargers/EVSEs fail, ruling out external charger fault
Codes mentioned: F2 fault code (home charger)
Repairs/costs cited: Diagnosis may involve ICCU, OBC, charge port, or high-voltage charging components. Parts often on back order. Some vehicles repaired multiple times without permanent resolution. Charging port replacement reported in at least one case.
Recalls/TSBs owners mention: Recall campaigns and TSBs address some charging issues; insufficient for full resolution in many cases. Dealership diagnostics sometimes inconclusive or unable to reproduce issue.
Charging cord and home electrical hazard (melting, arcing, surge damage)
Home Level 2 charging infrastructure damaged: 220V charging port showed melting damage and black marks indicating spark/arcing from vehicle side. Subsequent home electrical issues (lights flickering when HVAC activates) suggest vehicle-induced surge damaged home electrical system. Fire risk exists if outlet placement different.
When: Reported in 2025; timing unclear but associated with ICCU failure period.
Symptoms owners cite: 220V charging plug melted; Black marks on wall outlet suggesting arcing/sparking; Lights flickering in home after incident when unrelated loads (HVAC) activate; Home electrical panel potentially compromised
Codes mentioned: No vehicle codes; electrical fault inferred from damage
Repairs/costs cited: Home electrician inspection required; home electrical panel may need inspection/repair. Vehicle charging circuit failure suspected as root cause but not formally diagnosed in narrative.
Recalls/TSBs owners mention: None reported; Hyundai liability for home electrical damage not addressed in narrative.
Reduced power/limp-mode activation without clear warning
Vehicle suddenly enters limp-mode (12–25 mph max speed) or experiences abrupt power loss while driving, with little or no prior warning. Occurs during highway or local driving. Separate from but often precedes complete ICCU failure.
When: Occurs during driving; some instances while charging nearby or shortly after charging; one case at 75% battery charge.
Symptoms owners cite: Sudden loss of acceleration capability; Max speed drops to 12–25 mph without driver input; Vehicle struggles uphill; Brake and accelerator unresponsive or sluggish; Orange or red warning light follows within seconds to minutes; Turtle icon displayed (normally only at <1% battery, but occurs at high charge %); Quick progression from limp-mode to complete power loss (seconds to minutes)
Codes mentioned: Check EV System warning
Repairs/costs cited: Often ICCU-related; also reported with AC inverter failure in some cases. Inverter replacement required in at least two instances (one vehicle had inverter fail twice).
Recalls/TSBs owners mention: Recall software updates; insufficient for prevention in many cases.
Recall repair delays and parts back-order (extreme duration)
Vehicles await recall repairs for extreme periods: 6+ months in one case (Sept 2025–March 2026+), 122+ days in another (Dec 2025–April 2026). Parts allocation and distribution failures; some vehicles never taken full delivery. Hyundai's recall completion records may show false completion dates despite vehicles still awaiting repair.
When: 2023–2026; delays often 1–6+ months; some vehicles still unrepaired as of report date.
Symptoms owners cite: Part on indefinite back order; No estimated completion date provided; Recall campaign shows 'closed' in Hyundai system but vehicle still awaiting parts; Owner required to make payments on undelivered/unrepaired vehicle; Loaner car sometimes provided, sometimes not; Repeated contact with dealership yields no updates
Codes mentioned: N/A
Repairs/costs cited: Repair costs covered under warranty/recall when parts arrive, but timelines unpredictable. Owners make car payments (one reported $2,569.60 over 5 months) on unusable vehicles.
Recalls/TSBs owners mention: Hyundai case managers assigned; often no concrete timeline. Recall completion records appear inaccurate (showing 'closed' when vehicle still unrepaired). No compensation offered for extended loan periods or payment arrears.

12 V battery died after being plugged in to charge overnight. The 12V battery was replaced in May 2024 due to a similar issue. It seems that the ICCU recalls and software updates have not been fixing the problem.
The vehicle was being driven normally on city street and I heard a thump in the rear end of the vehicle. Very soon after, got a message on screen to check electrical charging system with the indicator lights for 12 volt battery and EV system illuminating. Parked the vehicle a kilometer after thump to deliver something to a friend (the car sat for 10 minutes). Resumed driving and then within a…
Known level 2 charging issue with Hyundai Ioniq 5 vehicles. Overheating issue with charging system, previously the issue shut down charging with a temperature exceeded ~212 Fahrenheit. TSB issued that "throttles" down charging rate, irrespective of the brand of level 2 charger doubling the time to charge the vehicle. Not as advertised and significantly reducing the utility of the vehicle.
Unknowingly my cars ICCU failed. I went to charge my car on December 23. The EVSE then immediately tripped the breaker. The EVSE gave an error code of a stuck relay fault and made the EVSE unusable. This happened to 2 different Juicebox chargers and both are not permanently disabled and need to be replaced.
Was charging the car at home in my garage when the charging session stopped. Opened the door and smelled electrical burning. Was able to put the car in neutral and push it out onto my driveway, fearing that an electrical fire could be disastrous. Called Hyundai roadside assistance and they had it towed to the closest dealership that can work on EV's (35 miles away). No report yet, but I'm…
Open ICCU Fuse, car would not charge
The car stopped both Level 1 and 2 charging. But Level 3 charging worked. When it stopped in the middle of Level 2 charging, it tripped my circuit and bricked my Juicebix Level 2 charger. Hyundai replaced the ICCU.
