12 volt battery dies after 2 years. Car is not starting and could stop working if it dies while being driven. The dealer replaced it But does not know why it died. I called the manufacturer but they were no help either.

Charging port burned during DC fast charging session, resulting in melted charging pin. Unable to insert CCS connecter due to melted pin obstructing insertion. Further damage to electrical systems unknown. No warning signs shown aside from vehicle charging session ending. Lack of safety systems to prevent melting/burning of charging pins leaves potential for general vehicle fire, battery fire, etc. Dealer has had car in possession for over 10 days with no update. Corporate contact has been unresponsive.

I have had my 2023 Ioniq 5 for 13-months. I have had two safety recall services performed - I understand those were ICCU software related. On [XXX] my car sounded a sudden alarm and a warning appeared saying to "STOP and Check Power Supply." I was not able to immediately pull over but found the ability to pull over within about 1/4 mile, the vehicle seemed to be losing power. It was frightening as there were many pedestrians and cyclists and I had no idea what was happening. The car was towed through AAA - we had difficulty getting it onto the truck as there was very little power and almost no power steering. The vehicle is now at the Rowe Hyundai dealership in Westbrook, ME. I was told the ICCU would need to be replaced as well as some kind of fuse. I am not sure I will feel safe driving this vehicle even after it is repaired. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

[XXX] - Took Hyundai IONIQ 5 to All Star Hyundai Pittsburg for servicing and recall issue. [XXX]: Saw an error reading CHECK ELECTRIC VEHICLE SYSTEM! on the IONIQ 5, after which a BlueLink rep was connected and stated I needed to take the car to a dealership ASAP. No appt available until July so advised to take car back to All Star. Called All Star and spoke to Josh who said there were no appts until [XXX]. Arrived All Star 9:15. I stayed until 3:15 with a lot of back and forth on diagnostics, warranty, how long for repair etc. Called Hyundai Customer Care and spoke Stephen who said the car was purchased less than a year and it would be under warranty for repair. I spoke to David, Manager All Star, who said he does not know when the diagnostics will be complete/ when car would be ready. Told me to go to Enterprise and get a rental at my own expense. Went to Enterprise Pittsburg in an Uber paid for by All Star. When I got there no cars available. Called All Star multiple times NO ANSWER. Took an Uber back to All Star to retrieve items in car and took Uber home at my own expense. Wednesday, went to Enterprise to obtain rental at my own expense and returned to All Star. They said they were waiting on Rep to further review the car. Today is May 28th and my right knee is now very painful and irritated from driving the rental as the 1st one had broken drivers seat and the 2nd one is still too low. I have spoken to All Star and Hyundai Customer Care to please provide a car rental similar to IONIQ 5 and I have received no assistance. I have spent almost $2000 on Ubers, rentals and gas. Hyundai still has not covered my rental expenses. I have spoken to approximately 16 reps of these companies and have received very few call backs or assistance. Today I called Hyundai Motor Finance to discuss monthly payments for a non-working car at All Star and was transferred and placed on a lengthy hold. No one returned to the phone call. I am seeking your immediate assistance. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORM

ICCU failed post software update. Driving home and was suddenly alerted electrical vehicle systems were malfunctioning, and shortly following (1 or 2 minutes), the car flashed a new warning telling me to stop the vehicle. Had I been on a busy highway or a one lane street with low visibility, it would have put me and my wife in danger of being struck by other traffic. Luckily, I was very close to home so I drove home and did not drive the car for a few days. while researching what to do, I had read about the ICCU failure and my problems were similar. I called a tow truck to get it out to a dealer. When attempting to shift the card into drive or reverse, the car would not move. Dealer has determined that my ICCU is in fact bad and is currently in the shop being replaced. Unknown how long this will take.

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.
