Defect Description:
ENGINE
Potential Consequences:
Called an ICCU failure. It's the control unit that charges the 12V battery from the high voltage battery. The unit fails blowing the high voltage fuse. Failure of this component causes the vehicle to all but shut down, even while driving. This is known by Hyundai. Others have said this happens at about 12 months and 10,000 miles. My car was 53/54weeks old and had 9,300 miles. This failure of this part may have also caused my AC to stop working. As pressure sensor on the 12V system that was working before the component failed was not working when I received the car back, resulting in another lengthy repair. I had about 0.7 miles warning, a yellow check EV system lit up, then the whole dash lit up saying to pull over immediately. The ICCU was replaced by Hyundai with the "2023 spec" version.

ELECTRICAL SYSTEM
Potential Consequences:
Was driving on the highway and got a warning to check electric system, then it asked to pull over due to battery failure. The car's 12V battery died and it wouldn't turn on. Had AAA replace battery, and then drove it to the dealership. The power gave out close to the service center and the car moved really slowly. It took the service center to diagnose the issue as ICCU failure. It's been 4 weeks and there is no ETA on the part.

UNKNOWN OR OTHER
Potential Consequences:
The problem is in "1-pedal" mode (which Hyundai calls "i-pedal"). This is an extremely convenient mode of driving in normal operation, yielding very smooth, passenger-friendly (acceleration and) deceleration by avoiding use of the brake pedals altogether. The problem is that the 2022 Ioniq 5 will *never* activate the brake lights ("stop lamps") when decelerating in i-pedal mode, as long as I apply any pressure at all on the accelerator pedal. This gives drivers behind me no notice that I am slowing down until I'm almost completely stopped. This seems to meet current DOT standards, but ONLY because I'm not using the brakes to decelerate. If I slow down at a similar rate using brakes, the brakes lights do turn on. I recently submitted a similar complaint to Hyundai: Consumer Affairs Case#: 21492175. For a more thorough explanation & demonstration, see this video from the Technology Connections channel on YouTube — he has exactly the same model as me (and I independently verified the behavior on my car with a driver following me): https://youtu.be/U0YW7x9U5TQ My complaint is to the DOT as much as to Hyundai: safety will be improved if the illumination of brake lights ("stop lamps") is required no matter what mechanism the driver is using to slow down, for all manufacturers and models (though this will likely only apply to Electric Vehicles or hybrids). I hope this can be made retroactive, which shouldn't be a great burden as I expect this could be implemented with a software upgrade. I believe the EU has such a regulation for cars sold in Europe.

Potential Consequences:
This is a rampant problem with my car as I have seen hundreds of the same reports throughout the many Ioniq 5 forums I am on. 4/22/23 my car died leaving me stranded. Apparently, the early revisions of the car I bought in March 2022 has a problem where the ICCU and inline fuse will go out over time leaving the car useless and frankly a hazard as I had to immediately pull over when the error message popped up. The issue IMHO should be a recall at this point. It has been sitting at a dealership awaiting the back ordered parts and Hyundai corporate denies that this is an ongoing problem even though I can see all the evidence widespread on the internet. Currently in the process of contacting a lawyer about a lemon law/class action lawsuit.

ELECTRICAL SYSTEM
Potential Consequences:
The 12-volt battery that controls everything in the car stopped being recharged by the 800volt battery, eventually causing the car to suddenly lose power and slow to 22 mph on the freeway. I was able to pull over 3 lanes and exit what was fortunately an uncrowded freeway. The car would not exceed 22 mph and soon stopped altogether and could not be moved. The main 800volt battery was at 56% charge, as the 12-volt battery went to 0%. The car was towed to the dealer. After inspection the dealer has confirmed that the ICCU system has failed and must be replaced, with a long back order and still no delivery date after 5 weeks. There were warning messages that appeared before the vehicle lost power, saying to check the battery electrical system. There should have been a warning that said “stop driving immediately as the electrical system is failing, and the car may stop even though the main battery is still well charged.”

Defect Description:
SERVICE BRAKES
Potential Consequences:
The IONIQ 5, like other electric vehicles, uses regenerative breaking. Regenerative breaking can be set at level 1, 2, 3, or i-pedal mode. This determines the strength in which the car will engage regenerative breaking automatically when the position of the accelerator petal is raised above the current speed. i-pedal mode is full one-pedal driving, allowing the driver to slow to a stop without use of the break pedal at all. At level 2, 3, or i-pedal, the car is capable of decelerating at a significant rate even when the driver is still pressing down on the pedal. For example, if you consider it as a percentage and take "foot off the pedal" as 0%, and "pedal pressed as far as it can go" as 100%, a driver could be traveling at 70 mph on the highway, with the pedal pressed at around 60%. The driver could then lift the pedal to only 30%, and the regenerative breaking would then slow the car to, say, 30 mph. This deceleration can be very strong when set to a high regen level. However, the break lights do not illuminate unless the driver takes their foot completely off of the accelerator. In i-pedal mode especially, it is possible to decelerate from highway speed to a near stop in only a matter of seconds, without the break lights ever activating. Other EV manufacturers illuminate the break lights based on the cars measured deceleration when using regenerative breaking, and do not have this issue. If the driver has driven other EVs in the past and prefers the one pedal driving mode, it is likely they will not even know that their break lights are not illuminating during heavy deceleration, creating a significant danger of being rear ended when driving in heavy traffic.

This determines the strength in which the car will engage regenerative breaking automatically when the position of the accelerator petal is raised above the current speed. i-pedal mode is full one-pedal driving, allowing the driver to slow to a stop without use of the break pedal at all. At level 2, 3, or i-pedal, the car is capable of decelerating at a significant rate even when the driver is still pressing down on the pedal. For example, if you consider it as a percentage and take "foot off the pedal" as 0%, and "pedal pressed as far as it can go" as 100%, a driver could be traveling at 70 mph on the highway, with the pedal pressed at around 60%. The driver could then lift the pedal to only 30%, and the regenerative breaking would then slow the car to, say, 30 mph. This deceleration can be very strong when set to a high regen level. However, the break lights do not illuminate unless the driver takes their foot completely off of the accelerator. In i-pedal mode especially, it is possible to decelerate from highway speed to a near stop in only a matter of seconds, without the break lights ever activating. Other EV manufacturers illuminate the break lights based on the cars measured deceleration when using regenerative breaking, and do not have this issue. If the driver has driven other EVs in the past and prefers the one pedal driving mode, it is likely they will not even know that their break lights are not illuminating during heavy deceleration, creating a significant danger of being rear ended when driving in heavy traffic.

Hyundai Motor America
Defect Description:
EXTERIOR LIGHTING
Potential Consequences:
This vehicle can use regenerative braking to slow fully to a stop. However, using regen to slow sharply does not activate the brake lights unless the accelerator pedal is fully released. This means that you can slow at a significant rate without alerting vehicles behind you that you are slowing. Vehicle should activate brake lights when slowing beyond a specific rate. This has been the case since vehicle delivery (3/28/22) and continues today. Occurs at all speeds.

Defect Description:
EXTERIOR LIGHTING
Potential Consequences:
Brake lights during I-Pedal or 1 Pedal driving modes. When under "I-Pedal" or 1 pedal driving mode brake lights do not engage unless foot is fully off the accelerator pedal. This is concerning as the vehicle can brake rather agressively with no indicition to the drivers behind you. The brake lights should illuminate when a sufficient amount of braking is occuring, not just when the accelerator is fully disengaged.
