Driving on freeway when adaptive cruise control turns off and had a sudden complete loss of acceleration, we had steering and brakes only. Sudden reduction of car speed in traffic could cause accident. Has only happened once in 20k miles. (no acceleration) Adaptive cruise control shuts off for no reason, but dealer couldn't replicate. In recent 8k trip we photographed warning on dash 17 + times after shut down. Dealer couldn't find any saved trouble codes for this. No warnings prior to any occurrence only after, dash turned off on acceleration loss.

HELP! I now regret that I bought a Hyundai Ioniq 5. I hoped the recent campaign would fix my problem, but I think it is now worse. While driving my speed drops 3 to 4 miles per hour, then the car lurches forward to regain my speed. At first I thought it was when using cruise. Now the car does it on the highway even when not using cruise. When it starts dropping the speed, the accelerator is not responsive. I have to wait for the car to slow completely down before the throttle will respond. I do not notice the problem around town. It seems to cruise fine for about 50 miles and then begin to slow and speed up out of my control. I think it is a safety hazard. It certainly drives me and my passengers crazy. PLEASE DO SOMETHING!!!

Driving on the highway, my car will suddenly lose power momentarily and the speed drop 3-5 mph. My accelerator is unresponsive. Then the car will accelerate quickly with a jerk to accelerate to the set speed. May occur on level ground but often occurs at the bottom of a hill. I have no control during this loss of power.
This car has detailed complaints online for the absence of a rear wiper causing zero visibility during afternoon rain and thunderstorms.

This car has detailed complaints online for the absence of a rear wiper causing zero visibility during afternoon rain and thunderstorms. In the event of a white out situation, the driver assistance systems fail to work due to hazardous conditions. You also cannot see out of the rear window or side mirrors because of a design defect. The car has been reported to Jenkins Hyundai of Ocala, where the service department is aware and informed me that Hyundai is aware of the safety concerns, but cannot fix the situation or will not offer a fix to the serious safety concern. The service department gave me the phone number to report this as a lemon to Hyundai Customer care where I was informed twice a manager named [XXX] has my case and would contact me, which she has not done. The case number given is [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on the interstate my 2023 Ioniq 5 SEL RWD experienced a failure with the front radar system stating that it was blocked. In reality there was nothing physically blocking the system which was verified on multiple pullovers to check the front of the vehicle. This caused the critical forward safety functions, HDA system, lane change assist functions, regeneration system, and smart cruise control to all be disabled. The car is available for inspection upon request and I have video of the car displaying the fault messages during the trip as it happened on multiple occasions.

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.
