When charging the car on an AC Level 2 charger, the vehicle overheats and charging fails. This is dangerous and can cause overheating/fire to electrical equipment as well as rendering the vehicle inoperable due to insufficient charge. There are no warnings ahead of time prior to failure. The problem is widespread and replicable, as evidenced by reports of forums, reddit, YouTube, and even a TSB issued by Hyundai that fails to adequately resolve the issue.

When starting vehicle, presents a warning message in instrument panel of "Check electric vehicle system". The stated description indicates: "This warning message is displayed when there is a problem with the electric vehicle control system. Refrain from driving when the warning message is displayed." This could be an issue with the battery system, or steering system that puts others in danger due to the unpredictable nature of the error. The Hyundai app that reports vehicle statuses does not show any error or diagnostic codes.

The charging system in the 2023 Ioniq 5 has multiple issues with connectivity and charging above a certain threshold. When charging at home using an electrician certified install by Merit and a county approved installation and Emporia EVSE 48A charger, the car prompts with a message that reads "Electric Vehicle Charge Alarm was processed. Your vehicle is not charging because of a connection failure. Possible reasons include: blackout, payment incompletion, charging stop button enabled." This has only recently started happening with the temperature in the closed garage reaching above 80F. The only way to rectify is to charge below 40A and this same issue is being reported by other Ioniq 5 owners via online forums as well. As it relates to DC fast charging at public infrastructure, the Ioniq 5 has a reliability problem with connectivity to the CCS1 ports that are used with Electrify America stations. The common denominator appears to be the charging port of the Ioniq 5.
We purchased our 2023 Ioniq5 approximately 7 months ago. We saw an article in the newspaper about the 2022 Ioniq losing power while driving. That has happened to us 3 times in the last several months so it is not strictly the 2022 model. One time was particularly scary as I was entering a busy freeway the car lost power and as m…

We purchased our 2023 Ioniq5 approximately 7 months ago. We saw an article in the newspaper about the 2022 Ioniq losing power while driving. That has happened to us 3 times in the last several months so it is not strictly the 2022 model. One time was particularly scary as I was entering a busy freeway the car lost power and as much as I pushed on the pedal I could not go more than 20mph. This happened for about 15-30 seconds then finally accelerated. My husband said he has experienced the same problem with this vehicle on 3 different occasions. Thank you.

2023 Hyundai Ioniq 5 (SEL, AWD) has bad ICCU (intergrated charging control unit). Will only charge at DC chargers reliably, level 2 or level 1 chargers will only work intermittently. Has been in the shop 2 weeks with no estimated repair date as the ICCU is on backorder. This issue is affecting a lot of Hyundai/KIA/Genesis customers who's vehicles share the same platform. The dealer won't even say where I am in line to receive the ICCU vs. everyone else in North America. This is really unacceptable for a car I paid almost $60,000 for.

1PE23011 · Loss Of Motive Power
Opened Jun 8, 2023 · Closed Apr 17, 2024
Status: closed (inferred from source dates) · Electrical SYSTEM:12V/24V/48V Battery; Electrical System:propulsion System:dc/dc Converter
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.
