2022 Hyundai Ioniq 5 Complaint Log

The contact owns a 2022 Hyundai Ioniq5. The contact stated that the vehicle was unable to charge at the charging station due the vehicle not accepting the charge. There was a message stating that "Charging Unsuccessful", however, recently the message only read unit connected to charger. No warning light was illuminated. The vehicle was taken to the dealer and diagnosed with a failure within the Internal Charging Unit. The manufacturer was not made aware of the failure. The approximate failure mileage was 21,000.

Vehicle receives an error regarding the battery and unexpectedly shuts down.

I started the car, and saw a "Check Electric Vehicle system" alert on the dashboard, and began driving. I was not far from my home, when I saw several messages saying "Stop Vehicle and Check Power Supply" - and the car began slowing and becoming unresponsive while I was in traffic. With my wife and infant son in the car, and being less than I mile from my home I was able to proceed cautiously and make it there. This is likely a known flaw in the integrated charge control unit of this model, which was subject to a voluntary service bulletin put out by Hyundai. I took care of the recommended service and firmware update in September 2023, but it did not prevent this electrical system failure - the service bulletin should have advised replacement instead of putting my family in danger without any warning.

I was driving on the freeway on Jan 17 when I heard a pop and then the electrical warning system on the car lit up. I lost power to the car and was only able to accelerate minimally. I turned on my hazard lights and was able to get to the shoulder of the freeway and fortunately was close to an exit and was able to exit the freeway. It was towed to a dealership and I was told there was a problem with the ICCU.

My 2022 Hyundai Ioniq 5 has experienced numerous 12V battery failures since early 2024. I ended up having to replace the 12v battery five separate times. The car fails to start with no warning. It has stranded me while transporting a pregnant spouse and a sick infant. Each failure required a tow and service visit. Hyundai claims “battery case corrosion” is to blame, but this is clearly a systemic electrical defect affecting many owners. This is a critical safety issue for families relying on the vehicle in emergencies. This is a safety and accountability issue affecting many families.

The cruise will shut off randomly saying the radar is blocked. When it does this the car decelerates very fast. Which is very dangerous in traffic. I’ve almost been rear ended a few times. It has also just started decelerating very fast when in cruise on highway for no apparent reason with no one in front of me.

Vehicle had the Service Campaign 997: Integrated Charging Control Unit (ICCU) software update in October 2023 at around 4,000 miles. It's now January 2024, 7,300 miles and the vehicle is currently at the dealership. The dealership confirmed it needs ICCU and Fuse replacement. Waiting for update on timeframe for ICCU part to become available. The car was showing "Check electric vehicle system" on the dashboard. It would not charge with Level 2 home charger. When I took the car to the dealership it started displaying a "Stop vehicle and check power supply" warning as I was arriving and the vehicle would not drive more than 25 mph.

The contact owns a Nuna Car Seat, Model Name: Rava, Model Number: (N/A), Model Type: (N/A), Manufactured Date: October 2023. The contact stated that the harness buckle was easy to release while attempting to secure the child in the car seat. The contact received notification of NHTSA Campaign Number: 24C002000 (Child seat). The manufacturer was made aware of the failure. The contact stated that the repair kit that was sent to repair the recall was an inadequate repair and did not address the safety concern regarding the harness buckle. The manufacturer was notified of the issue but offer no additional assistance. The contact was also denied a replacement car seat despite the car seat being under warranty.

ICCU failed and Fuse failed, causing car to go into turtle mode, barely made it hope to have it towed to dealer

The vehicle was being driven normally on city street and I heard a thump in the rear end of the vehicle. Very soon after, got a message on screen to check electrical charging system with the indicator lights for 12 volt battery and EV system illuminating. Parked the vehicle a kilometer after thump to deliver something to a friend (the car sat for 10 minutes). Resumed driving and then within a kilometer received a message that drive power would be limited -- significant decline in drive power... put my flashers on but did not stop because on busy street with no parking ... within two blocks, message of "stop vehicle and check power supply" appeared with full drive power ending within one block -- within that block, I was able to turn down a side street and coast down a hill to a parking lot. Attempting to turn vehicle off, the screen showed erratic behavior and headlights went on and off. Finally, was able to get everything off but was not able to lock the vehicle. If this drastic loss of power had occurred on a highway, there is a likelihood that such a power failure would have led to an accident.

The contact owns a 2022 Hyundai Ioniq 5. The contact stated that the pedestrian warning system was inoperable while reversing. Additionally, the contact stated that the battery was 92 percent charged; however, while driving 30-40 MPH, the message "Electric Power Failure" was displayed. The contact turned off the heater and the radio and continued driving. The contact stated that while parking the vehicle, the message "Electric Power Failure - Stop Immediately" was displayed and several alarms sounded. The contact notified the dealer and was informed to drive the vehicle to the residence and the vehicle would be picked up. The contact stated that while driving to the residence, the failure recurred, and the vehicle failed to respond upon depressing the accelerator pedal while driving uphill. The contact became aware that the vehicle had lost electrical power. The contact was able to veer to the side of the road. The vehicle was towed to the dealer, where it was diagnosed that the integrated charging control unit (ICCU) needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 9,600.

On Dec. 29, 2023, while drively slowly in a parking lot, we heard a loud "pop" from the rear of our 2022 Hyundai Ioniq 5 (approx. mileage 15,800). Then an amber colored dash warning came up saying "Check electrical system." Very soon thereafter, there was an audible warning alarm and a flashing red dashboard warning "Stop vehicle and inspect charging system" along with a red battery outline symbol. Almost immediately our top speed was reduced to around 20mph or so. We stopped in a safe place and had the vehicle towed to the closed Hyundai dealer (Zimbrick Hyundai West, Madison, WI). The dealer subsequently confirmed a failure of the Integrated Charging Control Unit (ICCU). The ICCU is expected to be replaced by Fri. Jan. 12.

My car suffered an ICCU and high-voltage fuse failure despite having been previously inspected as part of Service Campaign 997, which found no reason to replace the parts. After 24,700 miles and 16 months of service, the parts failed. This was only 4 months after the service campaign was completed. Similar to others who have reported ICCU failures, I suffered a rapid loss of power on the road, and within minutes, a complete loss of motive power. I received a “check EV system” and “reduced power” warning, followed very quickly by “check power supply, pull over immediately.” While I was able to pull to the roadside, this easily may not have been the case, causing significant danger. The dealer confirmed the issue and eventually replaced the parts. A loss of motive power within minutes or seconds is potentially life-threatening. Hyundai’s proposed fix for the issue — inspection and perhaps software update — is clearly inadequate to address the problem, since my vehicle failed after the service campaign had already been performed.

The car gave an warnings of “Check Electric Vehicle System@ and started slowing down in the middleman of the road. I could have been easily rear ended or got into a serious injury. After googling, it seems almost all if not most of ioniq 5 are having this issue after certain mileage

The contact owns a 2022 Hyundai Ioniq 5. The contact stated that the electrical charger was overheating, and the 12-volt battery was draining without warning. The contact stated that while charging the vehicle, the contact heard an explosion. The contact stated while driving 20 MPH, the message "Stop Driving Immediately - Return to Dealer"; the check engine warning light illuminated, and the vehicle experienced a loss of automotive power. The contact stated that on one occasion after turning off the vehicle, the battery remained active for 3 days, causing the battery to become drained. The vehicle was taken to a local dealer where the vehicle was diagnosed and the contact was informed that the water pump, the EV battery, the charge point, the inside batteries, the sensors, the navigation system, were faulty and needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure. The approximate failure mileage was 65,000.

The car started reporting error messages including "Stop vehicle and check power supply". It briefly went into limp mode before dying completely. Flat bed to dealer who can't begin diagnosis for at least a week. This sounds identical to the ICCU issue that many owners are experiencing.

The vehicle show an error message relating to the electrical system, refused to go over 24 mph for a short time, then went completely dark with no control and wheel locked. Dealer says ICCU + fuse is at fault, but there is no date for a new part. Vehicle is undriveable until new part comes in.

Feared ICCU leaving us stranded after reading so many reported failures, took car to dealership where they inspected and did some ineffective software update, few weeks later experience EV warning light and sudden loss of power, car wont go more than 25 so we parked and were effectively stranded. Dealer suspects ICCU....great. exactly what we wasted time trying to prevent. A KNOWN PREDICATABLE PROBLEM IS CALLED A DEFECT!!!!!!

Car died in a Wegmans parking lot and dealer is telling me it will take 8-10 days to diagnose the problem which is known very well to the manufacturer and dealers. The ICCU has failed.

My 12v battery died on 11/12 while my main battery still had 52% charge remaining. Had to jump the battery to get the electrical system to work. Since then several of the cars electrical systems are not working. This is a known issue online that Hyundai has responded to but the dealer is saying that they are not aware.

In stop and go traffic on freeway, car was moving at about 5 miles an hour but car kept moving, collision warning and automatic braking did not activate. Had to turn off car and coast to a stop. Nearly collided with vehicle in front

The car suddenly showed a warning on the screen asking me to park and in a few seconds went completely dead. It won't start at all. I can't even unlock the car. I had to call roadside assistance and have them tow the car to Ideal Hyundai dealership in Frederick, MD. It's been 4 days and the dealership can't diagnose the problem or won't communicate what the issue is.

The 12 volt battery keeps failing. Every time I contact Hyundai AutoNation it takes forever for them to do anything about it and they don't seem to understand

I was driving 75mph on the freeway and I heard a pop and then the electrical warning system on the car lit up. I lost power to the car and was only able to accelerate minimally. There was a warning of low battery and the vehicle was going to lose power. I turned on my hazard lights and was able to get to the exit and was able to exit the freeway safely. Once the vehicle lost power I was unable to open the charger door, start the vehicle, use any of the key fob functions and had to jump the 12V battery, only to die immediately after. There is no pre-warning to this happening, it just shows the alert and the car loses all power. There are also problems with the vehicle after being plugged in to charge and it says "Charging Unsuccessful", or stops charging after a short period of time. It also will not charge to full capacity at home or the charging station. I receive no warning lights or messages about why the charge is not working. It took weeks to get the vehicle into the dealer, making it extremely unsafe to drive and the error has almost caused a major crash. My vehicle has been at the dealer and has not been diagnosed with any issues yet. The dealer has provided me with a rental vehicle...in which now I'm paying for gas. Reading through these other comments...who knows how long it will be to get my vehicle back, yet I'm still making my payments...this isn't

We had charged the Ionique 5 to 90% and driven for short trips. We parked it then went to do some errands about an hour later. The dashboard warned that the 12 V battery was almost completely discharged and that I should start the car by placing the key fob next to the start button. I did that but it didn't start. I pushed the off button and then tried again and it refused to start and the dashboard flashed somewhat erratically. The battery then went completely dead. We called the emergency roadside assistance and they came within 30 minutes but the person who arrived said he knew nothing about electric cars and so we asked him to leave. Later we searched the internet and found others have had the 12 V batteries discharge. We also learned it could be charged with a portable charger. We called the dealer as it was now Sunday. One of the salesforce managers reassured us that is was OK to use regular car chargers on the Ionique 12 volt battery. Our neighbor helped us do this and it then started working. We followed the internet (a blogger's) instructions to go to the utility site and put it in the mode that would make sure the 12 Volt battery was drawing on the main powertrain to completely charge. We left the car on for 30 minutes and then it seemed to be working normally. We did some errands and it continued to work well. The safety risk is if this had happened on the highway and away from home. The car was recently taken in for the scheduled recall of ? something before this happened. There were no warnings or symptoms prior to this incident. There was several months ago an episode when I was driving that the power seemed to decrease and I was unable to accelerate and drove about 2 miles on mostly city streets at about 20 miles per hour. After I shut the car off and then my husband tried to start it the next day, it worked fine--that was the only other incident. I did not report that and it did not recur.

The contact owns a 2022 Hyundai Ioniq 5. The contact stated that the vehicle failed to start as needed. The contact stated that the battery had discharged. The contact had to jump-start the vehicle. There were no warning lights illuminated. The vehicle was taken to the local dealer but was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 29,000.

The vehicle lost traction power, failed to respond to presses to the accelerator and coasted to a stop. It gave no indication on the dash that there were any problems. Putting the car in park and then selecting drive again restored traction power and the car responded to pressing of the accelerator pedal. The car was not turned off and back on. During the incident: - The brakes, steering, air conditioning, radio and other electrical equipment continued to operate normally. - The car was configured for "Level 2" regen braking, but during the incident, when all pressure was removed from the accelerator pedal, the car did not "feel" like it slowed as normally did during Level 2 regen when there is no application of the accelerator. - The car was configured for "ECO" mode. The drive mode was switched to Normal and Sport during the incident but it had no effect. - The Power/Charge gauge on the dash neither indicated Power when the accelerator was pressed nor indicated Charge when coasting (as would be expected for Level 2 regen) or when the brake pedal was pressed. Car Information: - The car had about 75% charge and reported about ~260 miles of range. - The manufacturers app has not reported any "DTC" codes. - The car has no open recalls at this time. - Service Campaign 997 was completed August 23rd at dealer. - Service Campaign 9A1 was completed August 23rd at dealer. Additional Information: - A previous event similar to the above described event happened on August 21st where the vehicle lost traction power but gave no indication that anything was wrong. - Reported it to the dealer, but they were unable to find anything wrong or recreate the problem. - They applied the ICCU software update.

Aloha, Our Hyundai Ioniq5 has been out of commission for almost 5 months due to a failure associated with the ICCU recall. In December after months of working with Hyundai they finally shipped the car to an EV certified dealer to complete the recall and fix the ICCU issue. When we got the vehicle home it still shows electrical warning lights and will not charge at home. The recall fix didn't work and it still has the ICCU issue. The ICCU apparently can cause greater safety issues with the EV system when on the road. Its important the the recall fix actually works and in our case it did not. We have now been without the car for 5 months. We've had 5 different claim managers from Hyundai USA and we are still waiting on a fix. We are only filing a complaint because this could be a known reoccurring issue for other early Ioniq5 owners.

Every so often when I am driving on the highway, the car just looses power and I may catch a message that flashes on my display, "Emergency Braking". The event last no longer than about a second. When this phantom braking happens, so far, it has not been so severe to feel dangerous just unsettling!

The contact owns a 2022 Hyundai Ioniq 5. The contact stated while accelerating approximately 5 MPH from a stop, the vehicle lost motive power. The contact stated the failure had occurred two days in a row, with the second failure resulting in the vehicle coming to a complete stop. The contact turned off and restarted the vehicle and the vehicle operated normally. The contact stated that he placed the vehicle into SPORT Mode and the vehicle seemed to operate normally. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle had not been diagnosed or repaired. The manufacturer was informed of the failure. The contact researched online and related the failure to NHTSA Action Number: PE23011 Components (Electrical System). The failure mileage was approximately 16,500.

WHEN Home charging with my 50Amp Union installed Charger ,The Ionic5 Hyundai Overheats and shuts down charger ,.I purchased a new Charger 50 Amp. Installed by Union Electrican , Same results . I am very concerned that the Auto will catch on Fire in my garage. Please have mfg ,correct this problem This problem occurs multi times never charges more than 20 minutes

The contact owns a 2022 Hyundai Ioniq 5. The contact stated that while driving at 50–60 MPH, the Forward Collision Avoidance and Lane Assist warning lights were illuminated. The vehicle was taken to the local dealer, where the instrument cluster went blank. The dealer was unable to determine the cause of the failure. The manufacturer was contacted and opened a case. The manufacturer sent a technician to diagnose the vehicle. The technician stated that the VCU, battery, ICCU, and high-voltage battery needed to be replaced. The vehicle was repaired, but the failure recurred. The vehicle was taken back to the local dealer, but the vehicle was not diagnosed or repaired. The failure mileage was 19,000.

When the passenger front seat is occupied, the airbag disengaged warning light is illuminated; I have taken it to Hyundai service twice and they find no malfunction, yet the light remains illuminated

In the 1.5 years since I bought the 2022 Hyundai Ioniq 5 (new vehicle) there have been three instances where the car has failed to turn on or off due to rapid discharge of the 12 V battery. In all three occasions, the main battery was fully charged; however, the 12V discharged rapidly. The first two times this happened it took about 20 to 30 minutes of waiting for the main battery to charge the 12V battery before the car would start; however, on the most recent occasion, I had to call a tow truck in order to get the car jump started. I am very concerned about the safety of myself and my young children as I regularly use this car to go to work and take my kids to school. The only warning sign was a yellow light on the dashboard of the car—the indication that the main battery is charging the 12 V battery (this was happening more frequently leading up to the 3 instances, which tells me that the 12V battery needed charge, but was being insufficiently charged by the main battery). Because of the poor 12V battery, I avoid using functions that could deteriorate the 12V battery, such as air conditioning, and the GPS system. Hyundai recently sent a letter/safety notice about a faulty ICCU and fuse, and I will be taking the car in soon to get this repaired, but the repeated discharges of the 12V battery in the last 1.5 years has deteriorated the 12V battery enough that Hyundai should be proactively replacing it (not just the ICCU and fuse).

The vehicle will not fully charge at home at night on a level 2 EVSE. It charges for a few minutes, than stops entirely. When I restart the process, the same issue remains. I cannot charge the car fully at Level 2, 40amps. I wake up in the morning and only 5% of charge has been added.

The ICCU failed in the car. The car lost power while driving and showed an EV warning and the 12V battery warning.

After a recent update at my dealer my vehicle is no longer charging at advertised time. It now takes 2 to 3 days to reach full charge from 70 percent.

When my car is plugged in to charge it keeps stopping the charge. Example: Starts at 24% and stops at 28% I restart charge and it stops at 47%. Each time the charging port on the car is hot. This has happened multiple times. I now have to set reminders on my phone to check that my car is still charging so I can get to work in the morning. I am at the dealer now and they say there is nothing they can do because they have not been notified that it is an issue Thank you for your attention to this matter

Check electric charge error displayed, alarm sounding, loss of power to the vehicle while driving (limp mode).

While driving at highway speeds, there was a loud pop and the display showed "reduce power mode". We had to improvise a stopping place despite being far from home. There was no warning or issues beforehand. This incident was risky because of the loss of power while on a high speed thoroughfare and limited stopping options. The vehicle required a jump to move onto tow truck to take to dealership, where it has remained for two weeks without an estimate for repair. The symptoms.seem consistent with ICCU failure.

While driving on the highway on 8/12 at around 4pm, with another passenger, doing approximately 65 MPH I received a "Check Electric Vehicle System" warning on my dashboard. The car showed no prior warnings, no other lights were on. MyHyundai app was also showing no diagnostic issues with the car. The car battery was showing a 77% charge at the time. I swerved on to the shoulder, putting myself in danger as this is a really busy highway. I checked the car and could not find anything wrong. Hyundai had not contacted me regarding any recalls. I decided to keep driving to see if I could make it home to diagnose the issue. I made it another 20 minutes and as I was about to exit the highway at around 60MPH the car completely slowed down to 20MPH suddenly, and I was forced to swerve onto the shoulder once again. The car would not accelerate past 20 MPH. Fearing an accident, I called a tow truck and had the car towed back to my house. There were no warnings lights/signs prior to this event. The car completely slowed down from 60-65MPH to 20MPH in the middle of the highway and I was forced to make an emergency stop putting myself and my passenger at risk. The car was brought to the dealership on 8/14 which is the first time I was alerted that there had been a recall on my car and that the ICCU would need replacement. At no point did Hyundai ever contact me via email, text, call, or mail alerting me there was a recall prior to this scary experience. This is gross negligence on the part of Hyundai, as my vehicle could have been rear ended and caused a major accident on the highway.

Lost power while driving

Charge port on vehicle overheats when charging on AC charger and stops charging. Anything above 32 amps. The car is supposed to handle 48 amps.

Vehicle suspension in the rear feels unsettled when coming to a stop using regenerative brakes. If you hit a small pothole or recessed manhole cover the rear of the vehicle feels like the rear suspension is jumping. I've taken it to the dealer and they noticed it and also it occurred on a new ioniq 5 they had on the lot also.

We have owned an Ionic 5 for a year. For 8 months the level 2 charging system worked fine. We have two 40 amp level 2 chargers at two different locations which both charge the car at between 9.0 and 9.2 kW, well below the Ionic 5’s advertised capacity of 10.6 kW. After 8 months the charging session began to fail after only 1.5 hours due to the charge port overheating. Initially this seemed to be related to the ambient temperature, but now the failure occurs even when the ambient temperature is below 70. Once the session fails, the charging system keeps cycling between starting and failing, with each cycle lasting only a couple of minuets. Therefore it is very difficult to charge the car to even an 80% capacity. I am also worried about the impact this constant cycling is having on the battery overheating as well as the life of the battery.

When starting the vehicle I received an error that said "Check Electric Vehicle System". The vehicle seemed to be working fine at slow speeds in the parking lot at work. When I exited onto a city street I realized I had lost normal acceleration and could not go above 25mph. I pulled into a parking lot and turned the car off and on to see if the error cleared. It did not. Also received an additional error stating " Stop vehicle and check power supply". At that point I called roadside assistance for a tow. The vehicle is now at my local Hyundai dealership. Their service dept has stated they will take a look at it in 7-10 days most likely.

When driving for a distance at higher speeds, power will suddenly drop to the zero point btw acceleration and regeneration. You can feel the car start to drag as the power drops. If you press hard on the accelerator to stop it from slowing, it will suddenly jump forward. This has happened now on several long trips where I am constatly fighting with the car to keep it powered and not slipping into the zero zone. When it leaps forward the lane assist will also grab control and make it difficult to control the car. The car also stops slowing consistently when I take my foot off the accelerator and will move/ jump forward more than is typical for an EV instead of slowing the way an EV should as it regenerates. This all happened twice previously on a long trip and today constantly during a three hour drive. Does not feel safe!

While driving in heavy rain, I got warning: Stop and Check Battery. When I could find a safe place I stopped and read the Manual. I could find nothing helpful. My car was 63% charged. This was the 12v battery failing. I was then 5 miles from home. I turned off radio and lights, but could not drive without wipers. At about 2 miles from home the car slowed down. I continued to lose power as the rain got heavier. I was able to keep barely moving until I pulled into my driveway. I got out and locked the car by habit. I realized I needed it unlocked, but it was too late; it was DEAD. At the end the display read Losing Power and showed a small turtle. Indeed.

My vehicle began having charge failures at 13k miles. It went from working fine to not charging at all. The dealership has told me it is an ICCU issue and must be replaced. The ICCU is on back order with mo eta. I am left without a vehicle and no compensation.

Got a check electrical system warning and moments later the message to stop the car. Was able to pull into a parking lot where the car lost all power and had to be towed to dealer. Just received word that I have an ICCU failure and the part is on back order.
