2022 Hyundai Ioniq 5

On October 3, 2024, the Office of Defects Investigations (ODI) opened PE24028 to investigate alleged failures of Enel X Way's JuiceBox Level 2 residential EV chargers. The allegations were described as thermal incidents and electrical malfunctions, which could trip the circuit breakers in Juicebox owners’ homes and disrupt electric vehicle charge cycles. On October 2, 2024, Enel X Way posted on its website that Enel X Way North America would cease operations in the United States and Canada on October 11, 2024. The closure would potentially impact the charging app and supporting software. ODI sent Enel X Way an Information Request (IR) letter on October 21, 2024. Enel X Way provided an incomplete response to the IR on December 9, 2024. Enel X Way later provided a complete response to the IR on January 24, 2025. ODI reviewed Enel X Way’s IR submissions to determine whether further action is required. Based on ODI’s analysis, there was no clear trend in the cause of the failures described in customer complaints and warranty reports. Additionally, there have been no recent reports alleging safety issues. The available information does not warrant further action at this time. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency will continue to monitor for any safety trends and reserves the right to take additional action if warranted by future circumstances. To review the ODI reports cited in this Closing Resume, go to NHTSA.gov.

On June 8, 2023, the Office of Defect Investigation (ODI) opened PE23011 to investigate allegations of loss of motor power on model year (MY) 2022 Hyundai Ioniq 5 vehicles. Some consumers reported loss of motor power immediately after a warning lamp illumination or reduction of motive power while the vehicle was in motion. This investigation found that the Integrated Charging Control Unit (ICCU) may be subject to various conditions such as overcurrent, overvoltage induced at the end of charging, and certain thermal loading during operation that can damage its internal components and open the ICCU fuse, resulting in an inability to charge the 12-volt battery. The vehicle could eventually lose all motive power, increasing the risk of a crash. In July 2023, Hyundai issued a service campaign to address certain MY 2022-2023 Ioniq 5 and MY 2023 Ioniq 6 vehicles that may have low 12V auxiliary battery charging occurrences due to an ICCU fault and may set the DTC P1A9096 “DC/DC Converter Input Voltage Sensor Fault”. On March 15, 2024, Hyundai filed Safety Recall 24V-204 for 98,878 MY 2022-2024 Hyundai Ioniq 5 vehicles and MY 2023-2024 Hyundai Ioniq 6, Genesis GV60, Genesis GV70 “Electrified” and Genesis G80 “Electrified” vehicles. The recall remedy provides an inspection, and if necessary, a replacement of the ICCU and the associated fuse. The ICCU software reduces the risk of overcurrent and implements voltage peak reduction at the end of EV battery charging. The recall also includes a software update that revises the electric water pump operational threshold to reduce thermal loading during charging and driving. In view of the recall action being taken by Hyundai, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

The Integrated Charging Control Unit (ICCU) has failed repeatedly on this vehicle. It has been replaced three times by Haselwood Hyundai dealer since the vehicle was purchased new in 2021. Dates: 9/8/2023, 12/19/2024, 9/30/2025 at approximately 17k, 35k, and 50k miles. Each failure presents the same way: the ICCU stops charging the 12V battery from the high-voltage pack, the 12V drains, and warning messages appear on the dash: Check Electric Vehicle System. The vehicle then loses power or will not start and becomes inoperable [on numerous occasions the vehicle lost power/would not start at, leaving family occupants stranded. The vehicle also required jump starts on at least 25 occasions. Safety risk: an ICCU failure can disable the vehicle without meaningful warning. A loss of 12V power affects power steering assist, braking assist, hazard lights, and airbag readiness, and has left us stranded away from home as the car has to be jumped every time. Each failure was diagnosed and confirmed by a Hyundai dealer, which replaced the ICCU under warranty. Repair orders documenting all three replacements are available on request; the replaced units were retained by the dealer. The vehicle remains available for inspection. Despite three replacements, including under the ICCU recall and the extended warranty coverage Hyundai issued, the defect has recurred, which suggests the replacement units share the same defect as the original.

The Integrated Charging Control Unit (ICCU) in my 2022 Hyundai IONIQ 5 failed while the vehicle was charging. The vehicle had been connected to a Level 1 charger for a multi-day charging session when it unexpectedly stopped charging before reaching the selected charge limit. After the failure, the vehicle could no longer successfully charge using either Level 1 or Level 2 charging. When connected to a charger, the vehicle would initially appear to begin charging, but charging would then stop and the dashboard would display an electrical-system warning instructing me to inspect the vehicle’s electrical system. There was no warning or indication of an impending ICCU failure before this occurred. This created a significant reliability and safety concern because the vehicle effectively lost its ability to AC charge. Had I driven to a destination expecting to recharge there without realizing the charging system had failed, I could have been stranded without sufficient range to continue driving. I brought the vehicle to a Hyundai dealership, where technicians diagnosed the problem as an ICCU failure. The dealership subsequently replaced the ICCU. My vehicle had previously received Hyundai’s ICCU-related software campaign/recall update. Despite having that update performed, the ICCU later failed and required physical replacement. I am submitting this complaint because the prior software remedy did not prevent the ICCU failure experienced by my vehicle.

We had a previous issue with our 12V battery not charging, which totally bricked the whole car. Hyundai updated the charge management system software under the active recalls and tested the 12V battery, which after it was fully charged they said was fine. Now (a few months outside our warranty period for the 12v battery), our car was bricked again and was so dead that we could not even start it/charge the battery with a jump start kit. We were stranded on the side of the road (where we had parked for an event we were attending) and the next day Hyundai towed the car to the nearest dealer (3 hours away). It took a week for them to even look at our car and diagnose it. When they did, they said the 12v battery had "just died" because "it was old". There were zero warnings about the 12v battery not charging before it died. There were zero DTC codes. They refused to replace the battery under any warranty/the previous recall and we ended up paying out of pocket. The more concerning thing is that they claimed "nothing is wrong with the charge management system" which is clearly not the case. Even older 12V batteries don't just die after leaving them for a few hours - especially to be SO dead that they can't even be revived. I no longer feel safe driving the vehicle anywhere that I can't get a cab ride - who knows when it will just decide to stop working?

This report is an addendum to report 11762283 that was made yesterday. The vehicle allows driving with the rear liftgate ajar, however under some circumstances it engages the EPB when the vehicle comes to a stop while the gear state is still Drive. The gear state of the car remains in Drive when the EPB engages. This presents the driver with the choice, in the middle of the road and possibly in the middle of an intersection, of either exiting the vehicle and rearranging contents of the vehicle to allow the rear liftgate to close, or activating the accelerator to continue driving with the traction motor overpowering clamped EPB. Neither option is safe. I have attempted to reproduce this unsafe state of the vehicle and was successful in one case and unsuccessful in another. My hypothesis for the differentiating factor is the top speed reached prior to decelerating to a stop: in the first case, 13mph, and in the second, 15mph. I have attached a single frame from one of two videos, of the successful case. The instrument display shows gear state is Drive, the car is moving, high torque is being applied by the traction motors (but typically the screen center shows ADAS state, and there is no indication of instantaneous traction torque), and the EPB is engaged. The car is in the middle of an intersection at the time.

After coming to a stop at a stop sign, and while the gear state was in Drive, the vehicle auto-applied the electronic parking brake because the tailgate was ajar. Gear state remained in Drive. Upon accelerator input, the parking brake did not release, and the vehicle delivered propulsion torque overcoming the parking brake. As a result, the vehicle accelerated and drove several blocks with the rear brakes fully clamped, which was only effectively indicated by a smell and smoke emitted from the rear wheel wells. An irritating repetitive audio and large flashing visual alert in the display cluster indicating the tailgate state distracted from any additional indications that may have been displayed. That distracting indication was continuously active from when gear state was first switched to Drive and did not correlate with EPB engagement.

Active powertrain failure on my 2022 Ioniq 5 SE, which poses an immediate and severe safety risk. On May 18, 2026, the vehicle suffered a catastrophic loss of power and a complete failure to charge. At Murdock Hyundai of Lindon, technicians diagnosed it with trouble code P1AA600 and recommended a total high-voltage battery pack replacement at a cost of over $44,000. Immediate Fire & Safety Risk: The dealership technician explicitly warned me that if I continue to attempt to drive or plug in the vehicle, it will cause an electrical fire. Visible Electrical Arcing: The service technician stated that they physically witnessed an electrical arc occur when connecting the vehicle's high-voltage charging components. The technician's diagnosis strongly points to a catastrophic internal short circuit or a failed Power Relay Assembly (PRA) within the high-voltage housing. The company completely stopped working and Hyundai would not help. This has been an ongoing issue with other cars too. I tried multiple times working with both the deal and Hyudnai.

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.

Some IONIQ 5 (NE EV) and IONIQ 6 (CE EV) vehicles may exhibit a vibration noise coming from the battery system assembly (BSA) lower cover. This may be caused by the lower cover becoming loose around the center mounting bolts. Follow the procedure in this bulletin to replace the mounting bolts and install cup washers with each bolt to hold the cover in place and resolve the noise on affected vehicles.

Some Hyundai vehicles may be equipped with a parking distance warning (PDW) sensor(s) that may trigger various DTCs and display warning messages on the instrument cluster, resulting in the PDW sensor(s) failing to detect nearby objects or triggering multiple false alarms. This condition may be a result of external damage to the PDW sensor membrane or sensor cover from rock chips or road debris, a collision, or previous vehicle repairs or modifications.

Certain 2022 – 2024 model year IONIQ 5, 2024 model year IONIQ 5 Robotaxi, and 2023 – 2025 model year IONIQ 6 vehicles may require a replacement of the Integrated Charging Control Unit (ICCU) and ICCU Fuse.
