2023 Hyundai Ioniq 5 Owner Complaints

I've owned this car for 4 months now. We own 2 electric cars, 1 ioniq 5 and 1 Fiat 500e. We have a level 2 charger in the garage. A month ago I noticed the ioniq stopped charging overnight. When I tried the next day, it charged for about 30 minutes, then I would get a msg on my phone saying charging had stopped. I can remotely start the charging again, but then it would stop every 10 or 15 minutes. This is still happening. The Fiat has no issues charging, leaving me to believe it's not the charger that is the problem. I've even reduced the charge to the middle level but it hasn't helped. I will be taking this into Hyundai this month for them to see what's wrong.

When using i-Pedal (one-pedal driving) mode in this vehicle, it can decelerate at a very fast rate but does not illuminate the brake lights unless the driver’s foot is completely off the pedal. For example, I can be driving 60mph and decelerate to ~2mph as quickly as other drivers coming to a complete stop, but my brake lights will not illuminate until my foot is **completely** removed from the pedal. This is contradictory to the way one-pedal driving works, since coming to a smooth and slow stop requires that you slowly lift off the accelerator pedal, during which the brake lights do not illuminate because your foot is still pressing the pedal (albeit less and less as you come closer to the stop).

2023 Hyundai Ioniq 5 (SEL, AWD) has bad ICCU (intergrated charging control unit). Will only charge at DC chargers reliably, level 2 or level 1 chargers will only work intermittently. Has been in the shop 2 weeks with no estimated repair date as the ICCU is on backorder. This issue is affecting a lot of Hyundai/KIA/Genesis customers who's vehicles share the same platform. The dealer won't even say where I am in line to receive the ICCU vs. everyone else in North America. This is really unacceptable for a car I paid almost $60,000 for.

We purchased our 2023 Ioniq5 approximately 7 months ago. We saw an article in the newspaper about the 2022 Ioniq losing power while driving. That has happened to us 3 times in the last several months so it is not strictly the 2022 model. One time was particularly scary as I was entering a busy freeway the car lost power and as much as I pushed on the pedal I could not go more than 20mph. This happened for about 15-30 seconds then finally accelerated. My husband said he has experienced the same problem with this vehicle on 3 different occasions. Thank you.

When using the most aggressive braking energy recovery mode in the Hyundai Ioniq 5 (i-Pedal), the brake lights do not illuminate despite the aggressive nature of the braking provided by this mode. This mode brings the car to a full and complete stop and is very similar to commanded braking via the brake pedal. When using the L1-L3 braking energy recovery modes, the deceleration experienced by the car is more or less mild enough that it would be similar to a downshift in a manual transmission car. But the brake lights only illuminate if your foot is fully off the accelerator pedal. I am not aware of the regulations or SAE guidance to know if this is consistent with best practice, but it could be better with the brake light coming on once a certain deceleration (x m/s2) is reached. It is my opinion that a software change in the car's ECU could effect a fix for this. A mandatory recall would force the issue with Hyundai to actually do something about it. Note that Kia and Genesis share the same basic EV platform and may share the same logic fault in brake light activation. Here is a Youtube video that discusses the issue in a fair level of detail - https://www.youtube.com/watch?v=U0YW7x9U5TQ

EV goes into power limited mode when on interstate when going ~50 miles while driving 70mph or more. Happened each of my 3 times on interstate of about that distance. First time was Sat 4/29 while in eco mode with 70% battery and 82°F outside, 1 hr drive 50+ miles. Second time was in normal mode Friday 5/12, 55% battery 72°F outside 1 hr drive 50+ miles. Third time was in normal mode and it happened after 42 miles. I scheduled a service after the first incident but they were only able to take it on 5/31. When this happens you lose ability to accelerate and have to coast to the side of road and let it sit for 10+ minutes to clear and then can resume, I would take surface roads after it occurred. Impacts safety for self and others, as it drastically slows without brake lights causing a high chance of being rear ended. The last incident was close to it. As it was getting worse I stopped driving on interstate with it. Car has been at the dealership's service department since 5/31. They were able to easily reproduce once they finally got to it. They diagnosed a bit and then consulted design engineers. Diagnosed on and off for a couple weeks and have finally decided to replace the drive motor. Part received Friday 6/16, to be installed tomorrow 6/20. We'll see if that addresses.

Twice this week while charging my Ionic 5 the charging stops before it is completely charged to the set point. Once the set point was at 80% and once at 100%. Both times the charging stopped and I received the message below. None of the reasons listed in message was a cause of the stopping. I have called my dealer and they are checking w/service dept to see if I need a software update. I am waiting to hear back but there is obviously something wrong with the rate of charge. I am using a Jukebox home charger.

6/22/2023

Sometimes, the batteries trip while charging and don’t recharge, don’t charge at the expected speeds, or only charge partially. Recently, when charging at home all night and plugged into our Level 2 charger, I find find that the car has not charged at all overnight.

The Ioniq 5 offers a multi-level regenerative braking system, which slows the car down to varying degrees when letting off the accelerator pedal. While these systems work well to increase efficiency, the behaviour of the brake lights while in use is concerning. Very often the car is slowing considerably, enough to be akin to light braking, but the brake lights do not activate. This can be full let off the accelerator pedal and slowing with not brakes, or with a partial lift (especially on higher regen levels), where the vehicle is obviously slowing but the brake lights do not activate. This has been talked about on various forums and some review videos, and I expect this is not the first complaint placed about this issue. So far it has not caused a problem with my vehicle, but I have had to alter my driving habits to account for this, and it at times renders some of the vehicles technology dangerous to use, despite that technology being added to the car as a benefit to the driver under most conditions.

5/12/2023

The Ioniq 5 when using level 2 regen, level 3 regen, and i-pedal (one pedal driving), does not turn on the break light when decelerating, even if coming to a full stop unless the driver removes their foot completely from the pedal or hits the break pedal. These driving modes allow the driver to perform regenerative breaking almost to a complete stop without turning on the break lights and warning other drivers behind you. With i-pedal specifically, the driver can 100% perform all stop and go traffic maneuvers without using the break and never have the break lights activate. This appears to be the default behavior of all Ioniq 5 vehicles and is controlled via software. The vehicle does not appear to measure rate of deceleration so even if the driver were to decelerate rapidly, the brakes would not activate. This has been extensively demonstrated on youtube and the best video example of this problem can be found here: https://www.youtube.com/watch?v=U0YW7x9U5TQ

What component or system failed or malfunctioned: Rear electric motor. Specifically the "engine oil pump" that is used to cool the rear motor. The pump does not respond to MCU commands and does not cool the motor. This causes the motor to overheat after about an hour of highway driving causing the motor to provide VERY limited power. How was your safety or the safety of others put at risk: When the above happens the car experiences a delayed throttle, and very little power to accelerate. This occurs while traveling on a highway where you may need to pass, but no longer have the power to do so safely. Has the problem been reproduced or confirmed by a dealer or independent service center: Dealer took the car in and did not properly attempt to reproduce the issue. Then stated that if the car does not produce a DTC then there is no issue. The dealer has since refused to accept the car again. This has been reproduced here: https://www.ioniqforum.com/threads/rear-motor-not-operating-45-min-after-charge.46007/ Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others: No, I have just started the process of reaching out to the manufacture, and if this fails I will be using my states lemon laws. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear: No this issue does not appear to throw any codes, lights, or messages. The dash shows the rear engine producing no power, and the throttle will only show half when pressed to the floor.

While driving on the interstate my 2023 Ioniq 5 SEL RWD experienced a failure with the front radar system stating that it was blocked. In reality there was nothing physically blocking the system which was verified on multiple pullovers to check the front of the vehicle. This caused the critical forward safety functions, HDA system, lane change assist functions, regeneration system, and smart cruise control to all be disabled. The car is available for inspection upon request and I have video of the car displaying the fault messages during the trip as it happened on multiple occasions.

This car has detailed complaints online for the absence of a rear wiper causing zero visibility during afternoon rain and thunderstorms. In the event of a white out situation, the driver assistance systems fail to work due to hazardous conditions. You also cannot see out of the rear window or side mirrors because of a design defect. The car has been reported to Jenkins Hyundai of Ocala, where the service department is aware and informed me that Hyundai is aware of the safety concerns, but cannot fix the situation or will not offer a fix to the serious safety concern. The service department gave me the phone number to report this as a lemon to Hyundai Customer care where I was informed twice a manager named [XXX] has my case and would contact me, which she has not done. The case number given is [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driver was moving forward into a space in a parking garage between two other vehicles. Driver had pulled most of the way in and was slowly inching forward. As the car came to a stop, it suddenly lurched forward, hitting a concrete wall. The collision warning system did not alert, and auto-braking did not occur. The car was in Regen Level 3, and Auto Hold was not activated. In the months prior to this, the car twice had a similar situation when coming to a stop at an intersection with foot on the brake, then suddenly lurched forward, nearly rear-ending a car in front. There was no visible damage to the concrete wall, and a police report was not made. Hyundai says they want to inspect vehicle, but have not done so after a month. It is easy to believe that this was driver error, but it absolutely was not. Car lunged forward and accelerated into a wall with only the brake being applied. All of these events have occurred after the Hyundai Ioniq 5 software update was applied on 26 Sep 2023.

While driving in the one pedal driving mode (“iPedal”), it is possible to rapidly slow the vehicle while keeping the accelerator pedal slightly depressed, which is the expected result for this regenerative braking mode. While rapidly decelerating in this mode, however, the brake lights do not illuminate while the accelerator pedal is slightly depressed. Even though regenerative braking is active and the car is rapidly decelerating, there is no brake light illumination. The brake lights only turn on if the accelerator pedal is not pressed at all, which during typical one-pedal driving only occurs at the very end when coming to a complete stop, or when stopping suddenly during a cut-in or at a light. This is a serious safety concern because the vehicle will decelerate very quickly with no visual warning lights to other drivers behind the vehicle. I have noticed that this issue has been reported by other drivers online, but I have not yet taken the vehicle to be inspected by the dealer. There is no indication of failure on the dashboard.

The following is an incident that happened yesterday to my wife, who is an experienced driver: Whilst driving south on I5 from Seatac toward Tacoma in heavy rain with surface spray the screen above the steering wheel mentioned collision avoidance was not working and radar was not working. When I applied the brakes to slow down no response from the brakes. I then let off the brake and tried several times to apply the brakes each time with no success. I still had full control of the steering and could still steer the car. This lasted for about 30s then the brakes started working again. The error messages regarding collision avoidance and radar not working would continue to pop up even after the brakes were working. After stopping the car and turning it off and restarting several hours later the car no longer displayed any error messages. No vehicle or passenger were hurt in this incident, however if the traffic had slowed or stopped this outcome could have been very different.

The car proceeds by itself and does not stop even when brakes are engaged. This happened 2 times. Once in reverse and once forward, both caused severe damages to the car. In the forward incident, the driver was wearing seat belt but air bags deployed with impact.

Sound deadening foam inside the tire delaminates and causes SEVERE wheel imbalance. This is a widespread issue on all the Hyundai Ioniq 5 forums with this tire. Mine cost me $300 and countless hours to diagnose. IT also severely impacted the cars handling and prevented the car from driving over 46mph (in my case), which is extremely dangerous on interstates. My local tire shop balanced the tires with the maximum allowed amount of weights, but then the vibration was still there at 59mph. The Hyundai dealer then diagnosed it and they charged me $180 to do a dynamic balance. According to their results, the tires were "bad" and needed to be replaced. I went to Costco to replace the tires at a cost of

Car bounce if at 62 MPH had dealership check balance and rear two tires could not balance. Dealership de-rimmed tires and found the inner foam has fallen or detached from the inside of tire causing. Resulting in foam moving around inside tire throwing g off balance.

Hyundai Ioniq5 acquired new in September 2023 - mileage at the time of incident 10,800 miles - Michelin Primacy AS 235/55 R19 - OEM tires installed by the manufacturer. Front tire started to go off balance causing steering wheel vibrations and shaking that increased with speed - car was not drivable above 55MPH due to excessive shaking and vibrations of steering wheel - this presents safety concern as it may lead to loss of control and excessive wear and tear on other suspension / wheel components. I took the vehicle to a local tire shop (Town Fair Tire in Norwalk CT - authorized dealer of Michelin tires) - got wheels rotated, balances and alignment adjusted. The issue persisted - on the second visit tire shop dismounted one of the tires and discovered internal foam band unglued and clumped on one side of the tire causing off-balance. The shop recommended removal of the foam material and rebalancing of the tire to correct the manufacturing error. I contacted Hyundai and reported this as a safety issue as well.

7/31/2024

Due to an extreme failure in the integrity of the OEM tires, the vehicle experienced violent shaking a speeds in excess of 45mph. The shaking resulted from the extreme unbalanced nature of the wheels due to displaced noise-isolating foam inside the tire. As these tires were installed when the new vehicle was purchased, there is a significant issue with the fact that none of the dealership service stations visited to address this issue could identify a problem. Additionally, all three dealerships refused to work on the tires or help address an obvious problem for a vehicle with only 6,400 miles. While the warranty for the tires lies with Michelin, the complete lack of response or care by Hyundai representatives on a component with such a high failure rate is extremely unnerving and problematic.

3 issues: 1. 2 x, driving over a hundred miles the sensors get faults. None of the sensors work. Does not detect other cars. They updated my firmware, wiping the faults. 2. Once stopped at stop light, the sensors can start detecting items not there. 3. When parking the car does not detect items that are there. (I have video, dealerships so far refuses to fix) I am still trying to get them to fix it. Additional concern, talking to other drivers, they have similar issues and responses from the Hyundai dealerships. This is for both the Ioniq 5 and 6. Pictures: shows no other car image, or sensor detection. I took the picture a behind to give context. I can provide the videos if needed. Answers to question, separated with a comma: Yes, answered above, trying to get confirmed, the car has been inspected by Hyundai service center, and the errors were wiped by a update + reset.

Vehicle disengaged lane keeping ADAS without warning multiple times. Sometimes a warning beep would occur, but often on turns it would suddenly disengage without a beep or any other warning method causing me to have to yank the wheel to complete the turn correctly and avoid running off the road. This has caused me to not trust the system and fight the lane keeping feature just in case it suddenly turns off and goes into the other lane before I have a chance to correct the steering.

When approaching 60 mph the vehicle starts to vibrate / shake. Upon a dealer's recommendation they have rotated, aligned, balanced and changed the tires and repaired the rear rims, but they did not help. (Just cost us money). I contacted Hyundai and they suggested that I go to another dealer, which I did. They said it was a known issue and the there is nothing they can do about it. I can't say much about the safety aspect, but I'm sure it's not good when a car vibrates and no on seems to know why ...

The lower control arm broke off of the subframe during daily commute on the highway, which left the car completely immobilized and had to be towed. The incident could've been a lot worse if I had lost control of the car and swerved into others on the road. vehicle is currently being inspected by Hyundai dealership. Prior to the incident, there were no warning lights or symptoms.

The contact owns a 2023 Hyundai Ioniq 5. The contact stated that the vehicle failed to charge at 120 or 240 volts. The charging unsuccessful alert was displayed. The contact stated that the vehicle only charged on a DC fast charger. The vehicle was taken to the dealer where it was diagnosed that the ICCU (Integrated Charging Control Unit) that allowed both high-voltage and secondary batteries in vehicles to be charged had failed. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 500.

The navigation system in this car has an additional feature which is always enabled even if a destination is not programmed into the nav system which is supposed to warn drivers if they are going the wrong way on a highway. Intermittently the system erroneously indicates that the driver is going the wrong way. A voice warning is repeated issued and a warning symbol is displayed on the instrument panel. It is shocking, very distracting and frightening at first. Then it becomes a driver irritation, and eventually the driver tries to ignore the constant warnings, completely defeating the purpose of the safety feature. I’ve seen on the Ioniq forums where other drivers have reported this intermittent problem. Our local dealer would not check our car because the nav system was not failing at the time we brought it in. The problem can last for 5 minutes and then stop or can last for a duration of a car trip. For drivers unaware of this problem, they could easily be frightened enough to cause unsafe driving.

The rear video camera fails intermittently. It works sometimes and doesn't at times. The same with the rear cross traffic warning and pedestrian warning. I've taken my car to the dealer service center but they claim to not being able to reproduce the issue. I know the issue still exists since my husband hit a parked car while backing out of a driveway since there was no alert provided and the rear camera did not work.
