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.

I charge my vehicle using a home 48 amp charger. After about 10 months of ownership. I began to receive “charging unsuccessful”notifications after about ten of charging at the Maximum charging speed. I reduced the charging rate to Reduced and was able to charge continuously to 90% a couple times at that rate. However, I began to receive “charging unsuccessful” notifications at this rate as well and had to lower the charging rate to Minimum in order to charge continuously. I can not charge the vehicle at 48 amps and the vehicle can only charge at 5.7 kwh, rather than the expected 11.5 kwh. The vehicle has been repaired four times. I cannot take the car on long trips, or for intensive use, where I would need to quickly charge to car in order to continue using it. As this issue appears to be progressive, when will the car fail to charge at even the Minimum rate? When I am on the road at a remote charging station? When I have an emergency and need to use it?

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

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.

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.

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).

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

The car will only charge at half of the advertised Level 2 AC charging rate. It advertises it can charge at 48 amps; however, we cannot charge above 24 amps. If we charge above that rate the charging will stop. The issue appears to be well documented in online forums where if the charging port reaches about 100 Degrees C it will fault. There is a TSB they are installing but it just makes it automatically derate to ~24 amps which other than providing 15 minutes of higher power it doesn't at all solve the situation. Hyundai has recently stated that they are aware of the issue and they expect people to live with it and re-adjust their expectations; but it is fair to expect the car to perform as advertised. I also don't think any caveats about charging speed for weather or state of charge would be specific to level 3 charging; I am not aware of another EV in existence that doesn't provide its advertised AC charging level. It pretty clearly appears to be defective hardware. We also have friends who bought their car a month later (July 2023) and they are having the same issue; albeit they can still charge at 32amps. To answer the questions directly. - Charge Port - The cars cannot charge in time advertised making people drive without buffers and could run out of power on trips because they can only charge at half the rate advertised and couldn't charge overnight. - We are getting the TSB that will automatically reduce the charging rate this week. we had to wait over a month for an

Recently - my car has been encountering an issue and it has been slowly getting worse and worse. I have a 40 amp Level 2 charger I frequently use to charge my car. I first noticed it a few weeks ago, where my car seemingly stopped charging for no reason. I brushed it off, then unplugged it + plugged it back in and the rest of the session went fine. Lately, as temps have been rising I noticed the car failing charging sessions one, or two times per day. After doing some research, it turns out i’m far from the only one having this issue. Many other others have been experiencing the same issue as I, and the same degradation. Some people who were initially able to charge their car at 11kw, are now only to charge around 5kw, otherwise the cars onboard AC charger gets too hot and ends the charging session. I have started to see my car degrade as well, as I have had to lower my charge rate to 32a. I have tested out Level 2 AC charging on other chargers as well to rule out my charger being the problem, and it happens on them too unfortunately. To combat this AC charger overheating issue, Hyundai has released a TSB number 23-EV-003H. Unfortunately, the only thing this TSB does is kneecap the cars ability to level 2 charge at a decent rate. After the TSB is applied, once the car detects an overheating onboard AC charger, it will throttle the AC charge rate all the way down to around 5kw. This is unacceptable, when owners of the Ioniq 5 and 6 were promised a vehicle that is able to do 11

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.

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!

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 t

On 3/22/23, after using my car most of the day, I started my car to leave work and heard a small pop noise and a warning appeared on my dashboard to 'Check Power Supply'. As I was relocating to another parking spot, the car gave an audible beeping warning and another warning appeared on my dashboard to 'Stop Vehicle Immediately and Check Power Supply'. After speaking with the dealership, it was determined that my car had to be towed. I did not experience any loss of power/speed because I was only in a parking lot. The dealership informed me the next day that the car needed a new fuse and ICCU, but that the part was on backorder and they did not have an estimate on when they may get the part in. Repairs to my vehicle were completed on 5/3/23 (6 weeks) later.

The ICCU (integrated charging control unit) failed while I was out. I had to get the car towed to a dealership and it's been sitting in their lot for over two months. It took them two weeks to even confirm the issue, and the part is on indefinite backorder at the time of writing this. When the ICCU fails, the car cannot recharge the 12V battery. This forces the car to not travel above 25 MPH and when the 12V battery finally dies, the car will not be able to start. There was no prior indicators that would suggest such a critical component was about to fail, and apparently is such a common occurrence that there is a waitlist for the replacement. My ETA has been pushed back 3 times so far.

On Monday Jun 19 2023 around 7pm PT while I was parallel parking, I heard a pop from the engine area and immediately saw the center console show a warning message (one beep, then no further beeps): “Check electric vehicle system” I finished parking and left the car running while I starting to investigate online what this error meant. After ~2 minutes parked I got an active alarm (beep beep beep beep) that said “Stop Vehicle and Check Power”. I turned off the car. The battery was at 22% at this time, with about 44 miles of range. BlueLink Vehicle Diagnostic accessed from the in-car infotainment system said no issues found. The MyHundai App Diagnostic Report on my Android phone said All Systems Normal.

The car showed 67% battery life. But it would not charge any further. When we plugged it in, the voice would say "Charging Unsuccessful". The dash had the 'check electric vehicle' system error and when we tried to drive it, we got the red 'stop vehicle' error and alarm. We parked the car, called the dealership who made an appointment to have it diagnosed and told us not to drive it in the meantime. When it was time to take the car into the dealership, I turned it on and got 'turtle mode' and couldn't accelerate past 5mph and had trouble controlling the steering. I got about 100 ft past my driveway and the car completed powered down. It had to be towed to the dealership. When this car powers down, you can't do anything, you can't roll down the windows or unlock the doors or get the car in neutral. The tow truck driver had to use a portable battery and jumper cables just to power the car on so he could get it in neutral which releases the parking park so he could pull it on the flatbed. The dealership said our integrated charging control unit (ICCU) needs replaced; the part is on back order with no ETA. So, they have our car, and we're driving a rental and paying for gas again.

Previously charging at 40 amps the car would just stop charging completely, but after software update the car charge drops dramatically after 20-30 minutes. Research supports similar charging issues with 40-48 amp home chargers. The charge port seems to get overheated and automatically reduces charge speed. The technical service bulletin/software update has not fixed the charging issue.

What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
