When driving my new Hyundai ionic 5, the dashboard display is set up such that when I am in my preferred seating position, and my hands at 10 and 2 on the steering wheel, I cannot see the spedometer reading. I basically don't know how fast I'm going and less I change my hand position or move my head. This requires a fair more amount of time for me to take my attention off the road. This is not an isolated incident. I have asked my friends, who range in height from 5'2 to 6 ft 3 to do the same thing. They all report the same problem when they are in their preferred seating position. I am also noted many complaints about the same issue on the ionic 5 internet boards. This problem is caused solely by Hyundai's choice of a main display layout. This is the way it is laid out from the factory, and there is no way to change the speedometer position on the main display as a user.

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.

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.

The Ioniq 5 when using level 2 regen, level 3 regen, and i-pedal (one pedal driving), does not turn on the break light when decelerating, even if coming to a full stop unless the driver removes their foot completely from the pedal or hits the break pedal. These driving modes allow the driver to perform regenerative breaking almost to a complete stop without turning on the break lights and warning other drivers behind you. With i-pedal specifically, the driver can 100% perform all stop and go traffic maneuvers without using the break and never have the break lights activate. This appears to be the default behavior of all Ioniq 5 vehicles and is controlled via software. The vehicle does not appear to measure rate of deceleration so even if the driver were to decelerate rapidly, the brakes would not activate. This has been extensively demonstrated on youtube and the best video example of this problem can be found here: https://www.youtube.com/watch?v=U0YW7x9U5TQ

The Ioniq 5 offers a multi-level regenerative braking system, which slows the car down to varying degrees when letting off the accelerator pedal. While these systems work well to increase efficiency, the behaviour of the brake lights while in use is concerning. Very often the car is slowing considerably, enough to be akin to light braking, but the brake lights do not activate. This can be full let off the accelerator pedal and slowing with not brakes, or with a partial lift (especially on higher regen levels), where the vehicle is obviously slowing but the brake lights do not activate. This has been talked about on various forums and some review videos, and I expect this is not the first complaint placed about this issue. So far it has not caused a problem with my vehicle, but I have had to alter my driving habits to account for this, and it at times renders some of the vehicles technology dangerous to use, despite that technology being added to the car as a benefit to the driver under most conditions.

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.
