While driving in the one pedal driving mode (“iPedal”), it is possible to rapidly slow the vehicle while keeping the accelerator pedal slightly depressed, which is the expected result for this regenerative braking mode. While rapidly decelerating in this mode, however, the brake lights do not illuminate while the accelerator pedal is slightly depressed. Even though regenerative braking is active and the car is rapidly decelerating, there is no brake light illumination. The brake lights only turn on if the accelerator pedal is not pressed at all, which during typical one-pedal driving only occurs at the very end when coming to a complete stop, or when stopping suddenly during a cut-in or at a light. This is a serious safety concern because the vehicle will decelerate very quickly with no visual warning lights to other drivers behind the vehicle. I have noticed that this issue has been reported by other drivers online, but I have not yet taken the vehicle to be inspected by the dealer. There is no indication of failure on the dashboard.

There is no rear windshield wiper and the design of the car causes much dirt/gunk to build up HEAVILY obscuring visibility There are times where I'm driving at night (esp. when it's raining) where I can barely make out the cars/objects behind me. It is very dangerous

I was doing a 3-point turn in the driveway, and heard a pop sound from under the rear seats. A warning light came on in the dash, after a little bit of time the warning changed into an error that stated pull the car over and do not drive. OBD sensor reported codes P1A90 and P0C17. Car also went into "turtle" mode preventing it from being driven normally. Had it towed to the dealership, but took 2 weeks for them to inspect it. Once they got to it, they quickly determined it was a blown high-voltage fuse, and a fault in the ICCU (integrated charging control unit). Was told there is a national backorder on the ICCU and no ETA on delivery. I was also told I am one of three Ioniq 5s waiting for a new ICCU. I've seen many reports online of many Ioniq 5s having this same issue, and very long wait times for ICCU replacements.

We were driving vehicle on a neighborhood street with a speed limit of 45 miles per hour. When we got a "High voltage fault warning" from the car. I continued to drive about 10 second more and got a second warning. A different series of warnings appeared the last one being "please pull over and check your electrical system". We pulled into a neighborhood street, turned off the car. We decided to try to make it home which was less than 1/2 mile. Once I restarted the car, both messages cycled through the dashboard. Then the car lost the ability to accelerate past 25 miles per hour, no matter how much I stepped on the throttle.

The ioniq 5 has a one pedal driving mode, where the car will come to a complete stop without needing to press the brake pedal, similar to other EV's. In this mode, the gas pedal operates differently then in a conventional car - pressing the pedal approximately 1/3 of the way down represents neutral, where the car coasts. Pressing the pedal less then that - between 1/3 and not pressing it at all, applies braking power to the car, either through regenerative braking or the application of the physical brakes. The issue is, the brake lights on the rear of the vehicle do not light up when the gas pedal is depressed any amount. If you press the gas pedal as lightly as possible, the car will brake a fair amount but there is no warning to driver's behind that you are decelerating. I have twice been almost rear-ended, both times while slowing down in one pedal mode. I suspect the lack of brake lights until you take your foot fully off the gas pedal is a contributing factor. Other Ioniq 5 users have experienced the same issue.

The car suddenly cut speed to 20mph while traveling at around 40mph. No matter how hard I pressed on the accelerator, it did not go over over 20mph. The dashboard also said speed limited to 20mph. I had to pull over on the side of the road. Turn off the ignition. Then turned it back on. Then the car resumed to operate as normal. Luckily there were no other cars around so I could safely pull over. This could had been disastrous if it cuts speed again when I’m driving at 65mph on a busy freeway. I feel unsafe operating this vehicle because I’m afraid this will happen again in the near future.

Heard a "pop" sound and the car shortly after said "Check EV system." A few minutes later the car beeped loudly said "Stop vehicle and check power supply." A ODB scanner reported a P1A9096 code. This issue makes the vehicle inoperable with little warning.

The contact owns a 2022 Hyundai Ioniq 5. The contact stated while driving 59 MPH, a warning message advising to stop the vehicle due to low battery was displayed; however, the main battery was fully charged. The instrument panel lights turned off and the vehicle decelerated to 23 MPH. The contact veered to the right lane. While driving to the dealer, the vehicle stalled. The vehicle was towed to the dealer, where the Integrated Charging Control Unit (ICCU) assist, and the high voltage fuse were upgraded. Additionally, the battery was replaced. The vehicle was not repaired and remained at the dealer. The manufacturer was notified of the failure and informed the contact they could not provide vehicle rental assistance because the dealer was unwilling to assist. The failure mileage was approximately 28,000.

When charging the vehicle using a level 2 charger, the charging system will often trip for unknown reasons. This can happen after 1 hour or after many hours of charging. If using specific chargers, the charging will restart after a 10 second delay and oftentimes the car will continue to trip and start recharging multiple times. This can lead to heating up of the charging cord and potentially tripping the main breaker feeding the charger. In the car you can change the charging current from maximum to reduced to minimum. The issue appears to happen mostly on maximum and reduced charge, but has not happened on minimum yet. The issue is reproducible on multiple level 2 chargers and appears to be a common issue across numerous other owners. I have attempted to have the dealership investigate, but they are too new and or ignorant to electric vehicles that they won't take my advice on how to reproduce the issue and thus have not been any help. This issue is not related to DC charging which leads me to believe it's either electrical pin related or an issue with the AC to DC converter on the car. Besides, not getting the full use of the car I paid for, this issue can leave a user stranded if the charger fails to charge the car when expected, but also could be a potential fire hazard with the excessive heating of the charging module and associated charging cords. In the attached photos you can see how often the car charging will trip as I get a notification in my phone app each time it stops charging. If you're inside the car watching the dashboard when this happens, it will flash check EV system very briefly while it trips and restarts. No actual codes are thrown though.

On February 6, 2023 at approximately 9:50 a.m. I was driving my Hyundai Ioniq 5 SEL northbound on CA Highway 135, Santa Maria, when I heard a loud pop coming from my car. Within a few seconds my car lost speed rapidly, from 55 mph to 25 then a second later 22 mph . I tried to accelerate - there was no response - the car maintained the 22 mph. A message appeared on the right side of the dash board in an orange circle “check vehicle system” with a small upside down triangle with letters EV also inside this circle and a “small orange battery” picture showed on the left. I drove the car onto the shoulder of the road and with my hazard lights blinking, drove a half block making a right hand turn onto Miller Street to get off the Highway. I entered CHC Medical Building’s parking lot. Immediately upon entering the parking lot, my car stopped dead, before I had a chance to pull into a parking space. My car was now blocking cars coming in and out of the parking lot. I called Roadside Assistance and reported the above, the time was approximately 10:19 a.m. A tow truck (AAA) was requested by Roadside Assistance. After my conversation with Roadside Assistance, I turned the car on again and got power briefly - I moved the car into a stall space and waited. My car arrived at the Hyundai SLO dealership shortly before noon. The ICCU and fuse failed, and replacements have been ordered but the ETA is unknown Abrupt loss of speed was very unsafe

The car randomly drains the 12v battery. Twice it wouldn’t turn on when I had appointments to go to. The dealership service department has had my car since 10/27/22. They’ve replaced a bunch of parts & can’t fix the issue. I would occasionally get battery discharge warning messages when starting the car.

I was driving on the highway using advanced highway assist and the car became completely unresponsive. I was traveling 75mph on a major highway with a semi behind me and one to my right in the slow lane. The car stopped accelerating and I was unable to resume driving. I was forced to coast to a stop on the side of the highway. I had my daughter with me and were I not able to safely maneuver between the semi trucks, we could have been killed or seriosuly injured in a high speed crash.

Hyundai describes the lack on rear window wiper on this hatchback/suv as handled by the 'air wiper' the include air ducts allow for. The problem is that this 'air wiper' only works if it is actually actively raining AND you are driving at highway speeds. At any other time the rear window is almost always dirty and has no way of being cleaned while driving the car. One would need to pull over to a gas station to clean the window if on the road. Not sure you have a resolution section but the resolution would be to require Hyundai to install a rear wiper with wiper fluid mechanism.

The car randomly stops charging when plugged into either of my Level 2 home Juicebox 40 chargers before it reaches capacity, generally after adding another 4-8% to the battery. It was impossible for me to fully charge the car without plugging it in multiple times. The service people including the EV specialist said they hadn’t heard of this problem, and it was probably due to my charging unit at home. See the attached service and repair invoice . This was not true It is apparently a well-known defect in the Hyundai and Genesis cars using this platform and Hyundai is aware of the issue. it is not a problem with my charger. It happens whether it is hot or cold and generally when it is cooler as we only charge the car at night. Please note the following: 1.Saying this was a unique isolated problem was NOT accurate as this is a problem with many Hyundai and Genesis cars on this battery/charging platform. The Hyundai forums are full of these accounts, and they occur with all different types of chargers. For instance, see: a.https://www.youtube.com/watch?v=_3eh0BTSdng b.https://www.reddit.com/r/Ioniq5/comments/wrilke/ioniq_5_stops_charging_randomly_on_level_2_any/ c.https://www.ioniqforum.com/threads/charging-issues.42357/ d.https://www.kiaevforums.com/threads/charging-problem-automatically-stops-charging-at-home-the-charging-for-ev6-failed-please-check-vehicle.3659/page-12 3.The Ioniq 5 charges fine on level 3 superchargers 4.I spoke to Juicebox and they said other Ioniq 5 owners have reported the same problem in fact before I even mentioned the car I had, when I mentioned the problems, the technical advisor said, “Do you have an Ioniq 5?” He showed me downloaded graphs that show that the Ioniq 5 halts charges prior to being fully charged even though the charger is delivering power to the car. 5. I called Hyundai and they said they would look into this, but other people have received the same response, but nothing has been done

I parked the car end visited a store. Upon turning the car back on, the car freaked out and indicated that I needed to "Stop vehicle and check brake system." At the same time, the check engine light illuminated and the car entered limp home mode. CEL codes C164286 & C238001 appeared. The next day I brought the car to a Hyundai dealer who "fixed" the issue by removing a component that is unrelated to the braking and security systems and the car became drivable again for ~300 miles. I then went on two business trips and returned home. I drove the car and it again experienced the same error upon turning the car on. The braking system still functioned, but all electronic features were disabled by the car and braking involved a lot of force on the brake pedal to get the car to stop. For as long as I've owned the car, it has (infrequently) flashed the "Check automatic lane change system" when the car is turned on but the error goes away and doesn't return for weeks to months. The car is now back with the dealer who "fixed" the issue originally but their EV tech isn't always there to look at cars, even though the issue is not necessarily EV related as all cars (should) have brakes. Original incident: 9/8/2022, Second Occurrence: 9/30/2022

When the vehicle is parked and the trunk is opened, some percentage of the time the trunk does not remain in the open position and immediately closes. If the trunk is then opened additional times it generally remains opened. When the trunk unexpectedly closes the trunk object detection does not work and applies a great deal of downforce. When the trunk finally stops trying to close it remains in a locked position between open and close, it does not reopen. Mine and others safety is at risk as the trunk can cause bodily injury resulting from the trunk unintended closing. This issue happens around 50% of the time after the trunk is commanded to open. Two dealerships have been unable to reproduce this issue, but neither has tried multiple times, nor have they driven the vehicle to get the error/bug to reoccur. There are no warning or errors that this issue is going to occur. The only warming occurs three seconds after the trunk fully opens, the trunk closing audible rings. This error has persisted since shortly after first purchasing the vehicle.

When my IONIQ5 slowly starts and stops while the brake pedal engages or disengages, a noise, something like "click," comes from the rear passenger wheel house. Then, the brakes feel somewhat slippery. I think this has something to do with a transition between the regen brake and the traditional brake. The noise comes up every time I drive. Sometimes, I feel very unsafe because I am worried that the brake system fails.
