2022 HYUNDAI IONIQ 5 Complaints

I was driving and the car suddenly slowed down unable to accelerate much and showed a messaged saying 'Check Electrical Vehicle System‘. The service center says it is an ICCU problem. I have been waiting several weeks the part is still on backorder without any ETA.

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.

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.

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.

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.

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.

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.

The car (2022 Ioniq 5, an EV) lost power while driving. There was warning at the same time stating that the car is losing power and need to stop for safety. Minutes later the car completely lost power and can not be turned on. The car has to be towed to Hyundai dealer. It has been 2 months and 2 weeks and the car is till in Hyundai dealer's lot without being repaired. We were told by the dealer a control unit need to be replaced and it has to be shipped from Korean.

ICCU failure. The car dashboard display alert "Stop vehicle and check power supply" While trying to drive to the nearest dealership to inspect the alert, the car was limiting to 25mph, and eventually, the car died completely.

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!
