ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
- EV Fuse blown My Hyundai Ioniq5 EV electrical system stopped function on March 25th, 9 month after we purchased this EV, on a busy highway. It took Hyundai dealer 8 weeks to fix this issue. Due to the fix report, some fuse was blown. - Automatic Emergency Braking engaged On Jun 16th, when driving on HW 90 west bound, road was clean. No vehicle in front of me. The "Automatic Emergency Braking " was engaged. This could be very dangerous if the highway was busy.

SERVICE BRAKES, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
This is an electric vehicle that features “iPedal” driving, what Hyundai refers to as one-pedal driving. The main safety issue is that when you decelerate using one pedal, which is a fairly aggressive deceleration, the brake lights do not come on unless you lift your foot entirely from the accelerator or apply the brake pedal (which one would rarely do in iPedal mode). Hyundai needs to rethink their concept of operations for how their brake lights should operate. People are at risk of getting rear-ended. I didn’t realize this was how the vehicle operated until I was almost rear-ended today. Please push them to fix this issue.

ELECTRICAL SYSTEM, POWER TRAIN
Failed EV drive system. Error messages of electrical problems and shortly went complete dead. 12 volt battery was dead and won't charge. Car was towed to Ideal Hyundai in Fredrick MD. Dealer reported failed ICCU and parts for repair are on back order. Fortunately the failure occurred when pulling away from parking. If I had been at highway speed it could have been disastrous.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
I received a warning on my dashboard while driving "Check electric vehicle system". A few minutes later I received the message "Stop vehicle and check power supply". My car would not go faster than 20 MPH, and I had it towed to the dealership. They said it was an ICCU issue and the part was on nationwide backorder. My car has been at the dealership for 41 days.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
On 24 May 2023, I heard a "pop" sound when starting my Ioniq5 and immediately received warnings directing me to stop the vehicle and check the battery system. The car was taken to the dealer on the same day and is still out of service. The dealer notified me that the problem is due to an "ICCU" issue and that parts are backordered and they do not have an estimated date for the receipt of parts or repair.

VEHICLE SPEED CONTROL
Accelerator failed to engage on two occasions. 5/18/2023: First while driving on highway at 70MPH. Car slowed down gradually and I pulled onto shoulder. 5/19/2023: Again the next day driving 35 MPH. Pulled off road onto private driveway. On both occasions I turned car off and back on and it resumed normally. Fortunately no accident or traffic problem. I brought car to the dealer (Country Hyundai Northampton) to be checked and they could not find a problem.

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
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
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.

ELECTRICAL SYSTEM
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.

UNKNOWN OR OTHER
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.

ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
Started vehicle and heard a loud pop with immediate amber warning to check electrical system with 12 volt battery and EV electrical system warning lights illuminated. While driving to dealerships, vehicle slowed abruptly at Highway speed and warning message said to stop vehicle immediately. Towed to dealership with probable bad integrated charging control unit and high voltage fuse blown. Seems to be an issue with many ioniq 5s. Recall this vehicle!

ELECTRICAL SYSTEM, POWER TRAIN, FUEL/PROPULSION SYSTEM
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.”

ELECTRICAL SYSTEM
Vehicle will not charge at advertised speeds. Vehicle notifies me via phone app notification that “vehicle is not charging. Please try again. Ensure the vehicle infusions is off and gear shift is in park.” The car only charges if manually adjusted in settings to charge at minimum charging speed. The car used to charge at adversities speed and no longer does ever.

EXTERIOR LIGHTING
Rear brake lights do not properly come on in certain driving modes (i-pedal). The lights will only turn on if you completely release the accelerator pedal. The problem is, that you can significantly reduce your speed down to a stop without ever fully releasing the accelerator all the way.

EXTERIOR LIGHTING
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.

EXTERIOR LIGHTING
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.

SERVICE BRAKES
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.
