ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
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.

ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
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.

UNKNOWN OR OTHER, ELECTRICAL SYSTEM
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 appointment. - It has not been inspected yet but all they are going to do per the TSB is if we say we have the problem they do the software update. - There are no customer facing error codes. The issue first started in March the first day it was over 70 degrees. We did not have an issue last summer or over the winter. The longest we can charge since then at 40 amps is about 15 minutes. We have never even charged the car at 48 amps which is what it is supposed to be able to do.

When in motion, the “EV Start Stop”button is still allowed to turn off the vehicle if accidentally pressed. This happened to me while on the highway and moving about 15-20 MPH. The vehicle suddenly lose power and wouldn’t accelerate. I could not move the vehicle, without hitting the EV Start Stop button several times.

Hyundai San Jose dealership, Customer Service, told me, The fuse surrounding the Lithium battery is broken. This causes the whole car break down, and it is very dangerous to drive. My car has been in this Hyundai dealership over 5 months now, Hyundai cannot send the parts to San Jose Hyundai and I cannot drive the car. Also the 12V small lead acid battery in the front, broken down a few times. Cannot start the car. The whole car shuts down.

FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
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 11kw AC charging, or as claimed on Hyundais website, a Level 2 charge from 10-100 in 6 hours and 43 minutes. With my car throttled to 32 amps, it doesn’t charge nearly as fast adding hours onto the total time required to charge. This is an issue for me because I do not have a place to come home to every single night to charge my car, i’m only able to stop by the charger momentarily which means securing as much energy as fast as possible through Level 2 charging is very important to me.

ELECTRICAL SYSTEM
Car intermittently stops charging using a level two charger. Problem started approximately February 2023. Did not happen prior to that date. Car will issue a report through blue link app every 2 to 3 minutes reporting charging failure. This alert will happen approximately 50 times throughout the charging process until charging is complete.

TRAILER HITCHES
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.

ELECTRICAL SYSTEM
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.

POWER TRAIN, VEHICLE SPEED CONTROL, STEERING
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!
