A complaint is an unverified account by the person who filed it, not a
finding of fault. One complaint is one ODI number, which is how NHTSA counts
them.
A recall is the manufacturer conceding a defect, and the repair is free.
Whether one covers your particular car is a question only its VIN can
answer, because a campaign covers a production range rather than a
model year.

Crash test ratings
NHTSA New Car Assessment Program
NHTSA crashes a car into a barrier and a pole and measures what
happens to the dummies inside. This is what it awarded the 2023 Hyundai IONIQ 5, and it is a separate
question from what owners report going wrong later.

An investigation means NHTSA has decided a pattern is worth examining. A
preliminary evaluation is often closed with no action; an engineering
analysis is the stage that usually precedes a recall.
Loss of Motive Power

Closed preliminary evaluation · opened June 8, 2023 · closed April 17, 2024 · led to recall 24V204
the electrical system
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.

SERVICE BRAKES
2 deaths · 2 injured · crash · towed
Vehicle was involved in a double fatal. After viewing of dashcam video I suspect a malfunction of the vehicle may have occurred. The video appears to show the vehicle continuously accelerating despite the sound of what may be the driver attempting to repeatedly mash on the brakes. EDR records do not coincide with the dashcam video.

OnXXX, as we approached what I call the 6 o’clock position of a round-about in [XXX], we had braked almost to a full stop (0-5 mph) to wait on the car ahead of us to enter the round-about when we felt increasing movement. Despite braking, to wait on that car, our car with increasing speed started shoving that car into the circle. Fortunately, he was able to drive away from us, but that car had been damaged on the back and right side. With that obstacle out of the way, our car rapidly and exponentially increased speed - all while we were fully braking. Two witnesses said they saw our brake lights as we sped along. We hit the curb as we approached the 12 o’clock exit, and that turned us so …

The ICCU malfunctioned. Safety impaired because it likely impacted the ADAS, which concurrently failed. Yes, the problem has been inspected and confirmed by a dealer.

AIR BAGS
There is a yellow air bag (SRS) safety restraint critical wire harness underneath the seats and it's loose and hanging down touching the floor with lots of slack, very easy for a water bottle or any object to roll under there and pull it loose, which would disable a critical passenger safety system. This issue is reported by many drivers including myself, photos attached are from multiple people's experiences with this issue.

If this is your car and a dealer keeps failing to fix it, your state's
lemon law may require the manufacturer to replace it or buy it back. How
many repair attempts it takes, and how long you have to file, is set by
the state you bought in and by nothing on this page.
