2022 Hyundai Ioniq 5 Complaint Log

I have installed a hard wired 240V/48 amp EVSE for charging my vehicle at home. When charging at any current above 32 amps, the charger on the car is apparently overheating and causing charging to stop for approximately 3 minutes and restart charging then stopping again after another 30 seconds or so. Hyundai has issued a "fix" for this which simply throttles the maximum potential amperage delivered, resulting in delayed charging of the main vehicle battery. There are no warnings in the vehicle when this occurs, I just get a notification in the Hyundai app that charging was stopped. My only current workaround is to drop the amperage to 32 amps, which is 33% slower charging than I anticipated when installing the EVSE. Had I known of this issue, I could have opted for a less expensive and easier install method, but Hyundai issues no such warning when you purchase the vehicle.

The charge port in the car overhears when on a Level 2 (240v) charger running above 30 amps. This is happening to most 2022 Ioniq 5 cars, not just mine. Hyundai is aware and they just made it harder to charge over 30 amps. This is incredibly dangerous! They need to recall the associated parts before fires occur. It is unsafe to charge the car at the advertised rate!!

Known level 2 charging issue with Hyundai Ioniq 5 vehicles. Overheating issue with charging system, previously the issue shut down charging with a temperature exceeded ~212 Fahrenheit. TSB issued that "throttles" down charging rate, irrespective of the brand of level 2 charger doubling the time to charge the vehicle. Not as advertised and significantly reducing the utility of the vehicle.

Vehicle suddenly had no power on the highway. Error messages said to check the power supply. Prior to this there were error messages to stop the vehicle and check the power supply. Car would not drive more than 20mph. Car then died on the highway without any power when attempting to drive to the dealer. Problem was reproduced and confirmed by the dealer to be a faulty ICCU.

Issues with home charging at 40 amps port heats up and stops charging. When I purchased this car they stated it was possible charging at that rate.

The Draw-tite 76589 was purchased through Uhaul Canada for my 2022 Ioniq5. After a few months of use with a light trailer according to the specifications of Hyundai, Uhaul and Drawtite, it tore of a part of the vehicles frame. After the inspection at U-Haul and Hyundai dealership, they concluded that the problem occured because the hitch wasn't designed to mount on the specified by Hyundai mounting spot, hence it caused the damage. There are many cases like that on Ioniq5 forum as well as at different hitch installing companies who used this model. This model is now discontinued, although still sold, and was replaced by a 76632 model which mounts to the right location. Horizon Global did not contact the customers, not their distributors/dealers and doesn't compensate the customers who contacted them. After 7 months I still have the hitch on the car if you want to inspect it.

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.

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.

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.

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.

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.

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

Vehicle charging stops because the port gets overheat while charging on A/C. https://www.reddit.com/r/Ioniq5/comments/14g1922/charging_issues/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=1&utm_term=1 I have this exact same issue. It doesn't happens when you charge on 32amps EVSE. But 40or 48amps is the problem.

Hyundai has admitted that the integrated vehicle charger port overheats when charged at 48A. My vehicle was often stopping charge after only an hour or a few percent, leaving me without enough charge in the morning. Hyundai has offered a software "fix" for the problem which downrates the charging speed when overheating is detected, but this is only a bandaid solution and slows the car's charging speed by half, which was not what was promised when the car was sold.

1.We purchased the vehicle (Hyundai Ioniq 5, 2022 Model) on MAY 20, 2022. 2.The vehicle was acceptable until it started to fail on us while we were on the road, and soon after the vehicle crawled home at limited power and came to a stop, it would no longer even turn on. 3.Then started our nightmare with Hyundai USA. We called the service department and they told us, based on our brief description of what happened, that our vehicle would be unsafe to drive a single more mile (which was impossible anyhow because it wouldn’t turn on), and to tow our vehicle to Hyundai dealership in Fayetteville, AR for repair on DECEMBER 27, 2022 at our own expense. 4. From what Hyundai, Fayetteville, AR's service engineer named Evan told us, they have replaced the fuse no less than four times and it kept blowing when they went to test the vehicle. After the basic fuse replacement, it caused the problem to become worse, and revealed an ICCU problem, that then revealed acceleration and charging problems, and the initial fuse problem still persisted. Codes kept popping up, and whenever they fixed the current issue, another one would present. Long story short, it turned out the vehicle was experiencing “mass power surges,” issues with the batteries, and displaying codes for reasons they were unsure of, causing the basic fuse replacement to “pop.” They even called in a Hyundai Engineer directly from corporate to try to fix the vehicle, but according to Evan, even he had no idea what was wrong with the vehicle and had left with some data.

Highway speed vibration of entire vehicle, particularly steering wheel and seats. This continues despite wheel balance, forced wheel balance and replacing all 4 tires. Multiple trips to dealer without improvement. Test drive of a new, same model vehicle with same or more road vibration at high speed. Numerous same complaints on internet forums.

Vehicle Information: Year/Make/Model: 2022 Hyundai Ioniq 5 SE AWD VIN: [XXX] Mileage at issue onset: ~18,000–22,000 miles Purchase date: April 2022 Ownership type: Purchased new, paid in full Component Affected: Electrical System → Integrated Charging Control Unit (ICCU) / Charging System Problem Description: I am reporting a persistent and unresolved charging system failure involving the ICCU (Integrated Charging Control Unit) in my 2022 Hyundai Ioniq 5. This defect has rendered the vehicle unreliable and currently inoperable, leaving me without safe transportation for myself and my infant child. Over the past year, I’ve brought the vehicle to the dealership more than 10 times, including 6 visits in just the last 3 months, due to charging issues that were supposed to be addressed via multiple recall campaigns (e.g., Campaigns 228, 997, 9A1, 9B5, 272, TCP). Despite these attempted software and firmware updates, the issue persists and culminated in a total failure to charge in March 2025. The dealership confirmed ICCU failure again, but advised that the part is on indefinite backorder, with no timeline for repair or safe operation. This defect is dangerous, particularly as it can result in loss of power and stranding, with potential risks to driver and passenger safety. Hyundai is aware of this widespread issue among Ioniq 5 owners but has not issued a permanent fix or offered viable alternatives to affected consumers. Hyundai denied my Lemon Law claim despite substantial repair documentation and admitted ICCU defects. I have filed with the BBB Auto Line and IL Attorney General. I’m now preparing for legal action. This is not just a consumer issue — it’s a national electric vehicle safety issue involving Hyundai’s inability to resolve a known, system-wide defect in a core safety component. Attachments: Available upon request: repair invoices, dealer assessments, Hyundai’s denial letter, lemon law filings.

Charging at home with a 240v level 2 charger overheats the car charging port causing a charge failure. This is a potential fire hazard.

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.

Vehicle constantly disconnects from level 2 chargers, when charging interface overheats beyond threshold. This is an ongoing issue, and I have had this symptom on multiple chargers so it is specific to the vehicle. It is a common and known issue with the internal charging control unit (ICCU), yet Hyundai has refused to issue a recall to replace the faulty components. They have issued a TSB which throttles charging speed to minimum when the error occurs, but this is an unacceptable solution due to charging time constraints for many customers. I purchased the car with the understanding that I could charge at 48 amps, not 16, which is where I have to set it to keep from disconnecting constantly. The overheating components could also cause a fire hazard in certain situations.

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.

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

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 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

The contact owns a 2022 Hyundai Ioniq 5. The contact stated while attempting to enter the vehicle, the door failed to unlock. The contact was unable to unlock the door with the key fob but was able to unlock the door manually using the spare key. The contact stated that the main battery was not charged fully. The vehicle was not diagnosed. The manufacturer was contacted and a complaint was filed. The failure mileage was 889.

Brake lights do not illuminate in 1 pedal driving unless accelerator pedal is fully released. I often bring the car to a complete stop with the brake lights never illuminating until I'm nearly stopped, around 5 mph or less. I often see people ride up behind me quickly and have to slam on their brakes as they don't realize I'm slowing down so rapidly. This can be repeated at any time. I have not spoken to a dealer or the manufacturer about this, nor has it been inspected by any party. There are no warning lights, this seems to be normal behavior, many others have reported on this issue as well. This has been happening since I got the car.

Ok.... So, if anyone reads about Hyundai Electric line.... Ionic series... they would know that since Day 1, Hyundai has had problems with their electrical system. It 1st started with the system never charged the onboard standard 12V battery. I had to purchase Jumpstart boxes, I couldn't run my car ever on acc bc since day 1, my car has never been charging the onboard 12v battery. This caused me to not be able to start my car on more than 5 occasions. I had to ask strangers for help at times, locked out of my car on the side of the street, in parking lots, driving to Auto Zone after a complete trickle charge didn't work bc battery is so drained. During this drive, my cars safety features wouldn't work correctly, everything blinking and i had to make it to Auto Zone to have to buy a new GSM battery. I feared for my life on that drive. Certainly a safety issue. When I asked Hyundai on numerous occasions, they said there's no way for us to test if the recall fix we did actually is helping the issue. So I had to buy my own DC volt meter. I took that car in 4 times to deal with this issue. Now, after my last visit to Holler Hyundai in Winter Park a few months ago, now my car won't charge at home. I tested it with the 2nd charger. F2 fault code on standard home charger. Red lights on my ChargePoint charger. Car charges fine at DC Supercharger (6 times as expensive). I have told Daytona Hyundai multiple times (General Manager knows me) about how I have taken this in to have this problem fixed on many occasions. The GM said he apologizes, doesn't know why it wasn't fixed, they were unprofessional aside from him making many mistakes. The original dealer i bought it from was a bad experience and I do not trust them at all and would not buy from them ever again. I have video and pics of spiders in my car/roaches, etc. Dealership didn't even respond after I emailed them pics. I have bought and owned over 30 cars. This definately needs attention

The contact owns a 2022 Hyundai Ioniq 5. The contact received notification of NHTSA Campaign Number: 22V324000 (Parking Brake). The contact stated that while the vehicle was parked in a parking garage, the vehicle rolled away and crashed into a wall, causing damage to the front end. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 700.

Vehicle parked and unattended. Shifter control unit failed and vehicle rolled away. Vehicle front damage.

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.

Involved in a minor collision. Rear ended another car accelerating from a stop light (low speed). Forward collision warning did not activate. Auto braking did not activate. No airbag deployed.

The contact owns a 2022 Hyundai Ioniq 5. The contact stated while driving at 80 MPH the contact was pressing on the brakes while approaching a red light. The contact stated the vehicle would not stop, he pulled on the hand emergency brakes to stop the vehicle but the vehicle would not stop causing the vehicle to rear ended the vehicle in front of him and causing that vehicle to lose control and hit another vehicle. The contact was not injured and he was unsure if anyone else was injured. A police report was filed. The vehicle was towed to the dealer where the vehicle was diagnosed and the contact is unsure of the diagnosis. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was 11,200.

Following DC fast charging, I found the plastic cap (dead front) on pin #7 became dislodged and is missing. This missing component could expose the operator of the vehicle to potentially harmful electrical current when charging.

Following DC fast charging, the deadfront on the charging pin became dislodged and is missing exposing the conductive part of the pin to possible electrical shock to the operator.

I started my car up right after charging on a rainy day at 2500 miles exactly and got 5 warnings. Check battery, lane assist warning, abs warning, parking brake warning, forward collision warning and bling spot collision avoidance warning lights were on. More or less all these systems triggered a fault. I tried turning it off and on to no luck. As I drove to the dealer my breaks became steadily lighter and lighter with the manual break even clicking at times. My breaking distance was doubled by the time that i got there. Other owners are seeing the same issue. It sounds quite similar to the Kona Electric recall (20V-748). My car is unsafe to drive.

We just purchased this vehicle and I found this issue. We have not had any accident. This is just an professional OBSERVATION about a potential issue. The rear carpet mat has a slick and very smooth rubber underside. This factory carpet liner sits on top of the factory carpet. With the rear fold down seats in the upright position, there is no problem but the liner does slide easily around as there is no way to attach it to the regular carpet. I asked the dealer who dosen't seem to be interested in helping with any other issues including this and they suggested that I go to Walmart and buy a stip of velcro and stick it down. Paying over $58,000.00 for a car, I'm not about to do this as it is something that should have been caught in the design process. The problem will be when the rear seats are in the down position and someone puts a heavy object like a cooler filled with ice and drinks or a heavy tool box on the back area of the carpet liner. If you have to apply the brakes quickly or get into a accident, the article will be shooting forward on the liner very quickly and possibly striking the driver or passenger seat back or possibly in the back of their heads. The object could also move into the front seat area. Hitting the seat back or driver with this added force and or weight will be just more dangerous added that the air bags could possibly be going off. It would be like getting hit 3 times in a accident. First by another vehicle, 2nd with the air bags and 3rd from behind with whatever you put in the vehicle rear.

The contact's father owns a 2022 Hyundai Ioniq 5. The contact stated that as her father attempted to place the vehicle into reverse(R) while in park(P), the gear shifter failed to operate as needed. As her father exited the vehicle with the gear shifter in the park(P)position, the vehicle accelerated on its own into his garage. The air bags did not deploy upon impact. The contact's father was not injured and a police report was not filed. The garage door and pillar were damaged, as well as, the vehicle's driver-side door. The vehicle was initially towed to the dealer where the vehicle was inspected for the failure. The inspection found no defect with the vehicle and claimed that the failure was a result of human error. The dealer then drove the vehicle to a nearby independent collision center where the vehicle was repaired. Nearly two months after the repair, the contact stated that while in the vehicle with her father, the vehicle failed to move out of the reverse(R) position after backing out of the driveway. The contact stated the gear shifter eventually moved after multiple attempts and restarts. The dealer was notified of the failure and the contact later informed her that there was a recall on the vehicle for a shift control unit update(recall number unknown). The contact was instructed to bring the vehicle to the dealer to have the update performed. The contact notified the manufacturer about the failure and was given a case number. The vehicle was repaired. The failure mileage was 494. The contact stated that the vehicle accelerated into the door of the garage. Also, Hyundai eventually reimbursed the contact for the costs of repairs.

The contact owns a 2022 Hyundai Ioniq 5. The contact stated while driving in rain or snow the rear windshield failed to be cleaned. The contact stated that the failure was a dangerous while driving at night while the headlights from vehicles behind caused the rear windshield to become opaque. The contact questioned a dealer and was informed that the vehicle was designed that way and that the windshield needed to be cleaned manually. Additionally, the contact stated that the vehicle lost electrical power while driving at approximately 60 MPH with the cruise control activated. The contact stated that the vehicle lost motive power with several unknown warning lights illuminated. The contact pulled over, stopped, restarted the vehicle, and the vehicle functioned as needed. The contact stated that the failure recurred once. The manufacturer was informed of the failure. The failure mileage was approximately 22,000.
