2022 HYUNDAI IONIQ 5 Complaints

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.

I got the new update for my car from dealership, didn't know it effect ego mode, it's really lagging any power, need push accelerator all the way down to get any power, danger for left turn, please look into this thanks.

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.

The car started turning to the right on the freeway. Suddenly, alarm started going off and acceleration diminished.

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.
