Twice this week while charging my Ionic 5 the charging stops before it is completely charged to the set point. Once the set point was at 80% and once at 100%. Both times the charging stopped and I received the message below. None of the reasons listed in message was a cause of the stopping. I have called my dealer and they are checking w/service dept to see if I need a software update. I am waiting to hear back but there is obviously something wrong with the rate of charge. I am using a Jukebox home charger.

When AC charging my car, It quickly overheats and disables charging. I've measured the temperatures at 239°F using OBD reader. The only way to continue charging is to reduce charge amperage. If it is reduced to 32 amps the temperature seems to stabilize before reaching the 240° emergency cut off.

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 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.

The charging port on the electric vehicle appears to have poor cooling as the port frequently overheats when connected to any level 2 charger that is within the vehicle's approved specs. I've measured it going as high as 200 degrees F before the car stops accepting a charge, and even after that the port will remain piping hot until it is physically unplugged. This is quite dangerous as I mostly charge at night and am asleep when it happens in my garage. A quick search online shows that hundreds of Ioniq5 owners are having the same issue. Hyundai released a technical service bulletin(23-EV-003H), so I can take it into a dealer for a software update that will fix the issue. However, that update only succeeds in restricting how much current the car will accept in order to keep the temperature within safe levels. This means that the car I purchased cannot function safely as advertised.

12v battery died within 6 days and needed to be jumped. Another 4 days and the 12v will not hold a charge at all. This is a new 2023 Ioniq 5 Limited AWD. Odo on the lot was 13 miles. Odo at 10 days was around 280. Waiting to hear from Hyundai, but dealer confirmed 12v is bad. Currently unknown if ICCU is also faulty.

When using i-Pedal (one-pedal driving) mode in this vehicle, it can decelerate at a very fast rate but does not illuminate the brake lights unless the driver’s foot is completely off the pedal. For example, I can be driving 60mph and decelerate to ~2mph as quickly as other drivers coming to a complete stop, but my brake lights will not illuminate until my foot is **completely** removed from the pedal. This is contradictory to the way one-pedal driving works, since coming to a smooth and slow stop requires that you slowly lift off the accelerator pedal, during which the brake lights do not illuminate because your foot is still pressing the pedal (albeit less and less as you come closer to the stop).

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.
