How 2022 compares with every other Hyundai Ioniq 5
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

NHTSA investigations into the 2022 Hyundai Ioniq 5
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Recall 202470134,529 units in Canada
High Voltage
Issue: Over time, the integrated charging control unit (ICCU) could become damaged. As a result, the 12 V battery will not charge and could cause the vehicle to enter a reduced power mode. If this happens, and you continue to drive the vehicle, there could be a loss of power to the wheels. Note: This recall replaces Transport Canada recall no. 2024-174. Vehicles that were repaired under that recall also require this repair. This problem will cause a warning light to turn on and warning messages to display before any loss of power. For the Genesis GV70 and G80 models, only the electric versions (EV) are affected. Safety Risk: A loss of power to the wheels could increase the risk of a crash. Corrective Actions: Hyundai will notify owners by mail and advise you to take your vehicle to a dealership to update the vehicle software. The dealer will also inspect and, if necessary, replace the ICCU and ICCU fuse.
Recall 2024552824,695 units in Canada
Label
Issue: On certain vehicles, the compliance label may be missing information in French. The words listed on the label for "Tires", "Rims", "Front" and "Rear" appear in English only, when they should be listed as "Tires/Pneus", "Rims/Jantes", "Front/Avant" and "Rear/Arriere". Canadian regulations require this information to be listed on the label in both English and French. Safety Risk: These small errors do not affect vehicle safety. Corrective Actions: This is not a recall. The company has corrected the compliance label for all new vehicles.

Component that failed: High-voltage main battery pack assembly and associated electrical architecture. The vehicle and the component are currently located at my home and are available for inspection upon request. Description of Incident & Safety Risk: While attempting to drive the car and when connected to the vehicle to a standard charging infrastructure, a catastrophic internal failure occurred within the high-voltage system (Diagnostic Trouble Code P1AA600). Upon attempting to plug the vehicle in, active electrical arcing and physical sparks emanated from the high-voltage architecture. This structural manufacturing component defect presents an immediate, severe, and active fire and safety hazard to the occupants, the vehicle, and any surrounding property. The vehicle is currently completely un-driveable and unsafe to connect to any power grid. Dealer Confirmation & Inspection: The vehicle was driven to a certified manufacturer dealership service center. A certified dealership technician formally inspected the vehicle, reproduced the fault, and explicitly documented the active electrical arcing and sparking coming from the high-voltage pack in the official service records. The vehicle history was also escalated to the manufacturer's executive consumer affairs team, who acknowledged the intake statement but refused to authorize a remedy or repair. Warning Symptoms: There were no long-term warning lamps or prior symptoms leading up to the structural breakdown. The high-voltage system failure occurred suddenly and catastrophically, immediately triggering a critical malfunction indicator on the dashboard cluster at the time of the failure.

While the vehicle was parked in a garage and charging overnight, I briefly went to the vehicle to retrieve an item from the back seat. I was barefoot at the time. I opened the driver‑side rear door and reached inside with my right hand while my left hand was near the upper door area where the door seal is located. When my left hand grazed the door frame, it felt unusually sharp. When I touched the area again to determine what was sharp, I received a significant electric shock. There were no warning lights, messages, or prior symptoms before the incident. The presence of electrical current on an exterior door surface poses a safety risk during normal vehicle use.

I was coasting into a library parking space with my foot off the accelerator. The car accelerated even with my foot on the brake, jumped a curb and was stopped with above ground tree roots. The dashboard should have been lighted up with collision warning indicators and the automatic braking should have engaged. It did none of that. The car was totaled. Nothing was ever checked to see if it was a mechanical error. My insurer totaled the car.

On June 3, 2026, my 2022 Hyundai Ioniq 5 SE Dual Motor AWD (approximately 31,000 miles) experienced a sudden and severe high-voltage battery failure. Prior to complete failure, I noticed “Check Electrical” warning sign occurring simultaneously: a sudden and dramatic drop in driving range, dashboard warning lights illuminating, and the vehicle failing to charge properly at both home and public charging stations. The vehicle was still drivable at the time I brought it to an authorized Hyundai dealership, but displayed serious warnings indicating the HV battery system was critically compromised. Upon inspection, the dealership confirmed the main high-voltage battery had failed and required full replacement. The dealership has advised that the repair will take several months due to parts availability. This failure is not an isolated incident. Hyundai issued a recall covering 2022–2024 Ioniq 5 models for HV battery and charging system defects (including ICCU failure). My vehicle’s failure is consistent with this known defect pattern. Despite the vehicle being subject to this known systemic issue, Hyundai Motor America has declined to offer a goodwill buyback, and my case manager has stated the vehicle does not qualify for lemon law relief. The sudden loss of range and charging capability while the vehicle is in motion or in use presents a serious safety concern — particularly on highways where unexpected power loss could lead to accidents. I am currently without a vehicle for what Hyundai estimates to be several months. I am requesting NHTSA investigate this failure pattern in 2022–2024 Hyundai Ioniq 5 vehicles and take appropriate action to protect consumers from this known defect.

Complaint Summary: Mandated federal safety recall remedies performed on my vehicle have directly induced a cascading, critical safety failure of the vehicle's high-voltage propulsion management system. My 2022 Hyundai IONIQ 5 (VIN: [XXX]) was brought to an authorized dealer on XXX at 200,224 miles to complete safety recall Campaign 272 / NHTSA Recall 24V-204 (ICCU Software Update and Fuse Inspection). After receiving this software flash, the vehicle's electrical charging system failed (DTC P0D5C00), requiring a full hardware replacement of the Integrated Charging Control Unit (ICCU) on XXX. 142 miles after the physical replacement of the high-voltage ICCU, the vehicle displayed an emergency battery malfunction message on the dashboard. Diagnostic scans reveal active fault code P1BC700 in the Battery Management System. The manufacturer's dealership is now charging $1,909.77 out-of-pocket to replace the Power Relay Assembly (PRA).The current recall modifications for the E-GMP platform are failing to safely mitigate high-voltage current spikes. The electrical strain or servicing procedure required by the recall has directly compromised the adjacent power relays. This creates a severe safety hazard, leaving drivers exposed to subsequent high-voltage component failure immediately after completing mandated federal safety recalls. NHTSA should investigate cascading high-voltage component failures occurring in vehicles directly following the completion of Recall 24V-204.

I tried to start car and it started but would not go into drive. A message saying "12v battery voltage low. Stop safely." Was on the screen. I turned the car off and back on and was able to drive home. Once home I tried to charge the car but it would not charge. However I left it plugged in and came back several hours later and the car had charged some. I started the car and the messages did not appear. The next day i went to drive the car and the car was totally dead. The auto key would not unlock the car. Thank goodness , I was not driving when the battery died. I took it to the dealer. This is the 2nd 12v battery I have had to replace in 4 years. The first replacement was covered under warranty. I asked them to try to identify the root cause of the 12v batteries dying so quickly and they claim it is only the 12v battery. I feel unsafe driving the car now knowing it could happen at any moment again, maybe while driving. I think the problem is related to the ICCU as my symptoms are very similar to other people with ICCU issues.

2022 Ioniq 5 SE. ICCU failed April 2026 with around 29325 miles. Original owner. Purchased June 2022. I had the original Recall 272 software update performed back in February 2025, but the hardware still failed a year later. **Timeline of Failure:** 1. **Phase 1 (The Trigger):** Level 2 charging stopped unexpectedly before reaching the limit. It tripped my house breaker and unfortunately killed my Level 2 EVSE (Grizzl-E) with a stuck relay. Didn't think too much of it because I had to be somewhere. Car started up normally and I was able to drive throughout the day with no problems. 2. **Phase 2 (The Warning):** The next day, I attempted Level 1 charging. It immediately tripped the breaker. I tried another outlet on a different breaker; the breaker didn't trip, but the car failed to initiate a charge after three attempts. 3. **Phase 3 (Dashboard Error):** After third failed attempt with the L1, I took a peek inside and saw the dashboard had a yellow triangle. With the charger still plugged in, I sat in the driver's seat and turned the car on. The **"Check EV System"** error appeared. I turned off the car and went inside to call the dealer. I called the dealer and they said I can have it towed there. They also scheduled an appointment for the next morning. I went back to car to attempt to position the car to make it easier for the tow truck, but the check ev error was not there when I turned on the car. It said ready and I was able to drive around the block a few times so I figured I'll just try to drive to the dealer. I drove the car to the dealer the next morning. It took **one week** to get my car back. **Diagnostics & Parts Replaced:** The dealer confirmed the following codes and performed a full hardware replacement: * **DTC P1E1300:** AC Power Module Failure * **DTC P1A9096:** DC/DC Converter Fault * **ICCU Part:** `36400-1XAA0-AQQH` * **HV Fuse:** `375F2-GI040-QQH` * **Coolant:** Install of Pink Antifreeze (`00232-19098`)

Car started up normally and I was able to drive throughout the day with no problems. 2. **Phase 2 (The Warning):** The next day, I attempted Level 1 charging. It immediately tripped the breaker. I tried another outlet on a different breaker; the breaker didn't trip, but the car failed to initiate a charge after three attempts. 3. **Phase 3 (Dashboard Error):** After third failed attempt with the L1, I took a peek inside and saw the dashboard had a yellow triangle. With the charger still plugged in, I sat in the driver's seat and turned the car on. The **"Check EV System"** error appeared. I turned off the car and went inside to call the dealer. I called the dealer and they said I can have it towed there. They also scheduled an appointment for the next morning. I went back to car to attempt to position the car to make it easier for the tow truck, but the check ev error was not there when I turned on the car. It said ready and I was able to drive around the block a few times so I figured I'll just try to drive to the dealer. I drove the car to the dealer the next morning. It took **one week** to get my car back. **Diagnostics & Parts Replaced:** The dealer confirmed the following codes and performed a full hardware replacement: * **DTC P1E1300:** AC Power Module Failure * **DTC P1A9096:** DC/DC Converter Fault * **ICCU Part:** `36400-1XAA0-AQQH` * **HV Fuse:** `375F2-GI040-QQH` * **Coolant:** Install of Pink Antifreeze (`00232-19098`)

The car lost power while driving and an electrical warning was displayed on the screen. The issue was later diagnosed as a failure of the ICCU and blown fuse that had been previously recalled and replaced. Now it needs to be replaced again.

POWER TRAIN
Finished charge, low battery indicator on the dashboard. started to drive, within mile "pull over immediatedly" well documented and continued flaw with vechile ICCU component (that I had the software "patches" applied). Car will no longer accept charge (so now has the remaining charge before being a 3 ton brick) and cannot not be driven as if the 12v battery loses charge (which it will) I will lose powersteering and brakes.
