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.

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.

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.

Status: closed (inferred from source dates) · Equipment:electrical
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.
