ELECTRICAL SYSTEM
While driving on a 45 mph speed limit road, there was a "pop" noise and then alarms on the dash display that power was limited and stop the car. The car's speed was severely limited to about 10 mph for a few seconds while I pulled the car over, and then the car died. Everything was electrically dead. I couldn't even turn on the hazard lights or lock or unlock the car. I took a video of the dash display rapidly alternating between two alarm messages, "12V battery storage low. Stop safely." and "power limited." This website wouldn't let me upload the video, so I saved screen shots of the two alarm messages from the video. Shortly after I stopped the car, it all went dead. It scares me to think what would have happened if I had been on the interstate when this occurred.

I was driving the car 70 miles per hour in a highway. Car suddenly stopped and only go 5 mph. I was lucky no car behind me. If not I could be death today. I brought it to service and ICCU unit failed which is happened almost all Hyundai IONIQ 5. They replaced it with same ICCU and it will happen again. I think they want me to make an accident next time. This car is not safe to drive with this charging unit.

ELECTRICAL SYSTEM
We were driving our vehicle in a parking lot while on vacation and we got an error message “check electric vehicle system”. It then displayed the error message “stop safely and check power supply”. Four months ago, we had the same problem and had our 12 volt battery replaced and our ICCU updated. Our vehicle lost power while we were driving. We were able to drive the car safely to a hotel. But the ICCU needs to be replaced.

ELECTRICAL SYSTEM
My new 2023 IONIQ 5 became inoperable on 3 occasions when it completely lost power. This situation unquestionably impaired my safety on the first occurrence of power failure that happened without warning while I was driving; fortunately, I was able to coast to the side of the road without incident. In my repair visits to Hyundai dealers, the integrated charging control unit (ICCU) updated (twice) and the depleted 12-volt battery was charged. Repair visits resulted in loss of use of my car for a total of 31 days while it was in service. The 12-volt battery finally had to be replaced on the last dealer visit because it had could not hold a charge. The battery was barely a year old. No Hyundai dealer could assure me that the problem with the charging system was resolved. It was suggested that annual replacement of the 12-volt battery before the end of its normal lifespan might be required to avoid the serious safety risk of power failure while operating the vehicle. Hence, I am not driving my car with confidence that the safety risk risk was alleviated. I understand that Hyundai Motors acknowledged the ICCU problem and addressed it with a new ICCU in the 2025 Ioniq 5 model year. However, in my case, I have a still-new, expensive vehicle that I drive without feeling 100 percent secure that I am safe.

ELECTRICAL SYSTEM, ENGINE
I started my car and after a minute I received a warning saying to check my electrical system and safely pull over. After 5 minutes of trying to drive to the dealership the car suddenly slowed down to a max speed of 27mph and then shortly after slowed to a stop and turned off. The car would not turn on and eventually the 12v battery died. I tried to jump the car but the 12v would not stay charged long enough to put the vehicle into drive. It appears the ICCU is not working and cannot keep the 12v charged to make the car function .

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.

LANE DEPARTURE: ASSIST, LANE DEPARTURE: WARNING
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.

TIRES
There seems to be a wide spread issue with the foam on the interior of Ionic 5 tires, Michelin 235/55/R 19. The foam dislodges from the interior of the tire and causes severe vibrations when driving at over 60 mph. The issue causes the tires to be unbalanced and can cause damage to the car. Wondering why Michelin doesn't address this issue and issue a fix other than stripping the tires of foam. My Hyundai dealer told me this is an on going issue and they have received no guidance from Michelin or Hyundai.

ELECTRICAL SYSTEM
During normal driving with car charged to 95%, I heard a pop coming from the rear of the vehicle and saw an immediate warning about electrical system malfunction. I drove the car for less than a quarter mile and pulled over. I then received instruction on the dash to power off the car which I did. The car was towed to the dealership who diagnosed an ICCU failure. It had been to the dealer twice for safety recall notices related to the same issue. This is a known problem with this type of vehicle. Awaiting replacement parts. This problem will cause complete loss of power to the vehicle. Fortunately I was able to pull over and park in a safe space before this happened. Obviously complete loss of power is a potential safety issue, thankfully systems alerted me to the problem. I have no idea if the replacement part will be of the same lot that failed in the first place.

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 ...

It is regularly very difficult to see the digital speedometer on this car because it is blocked by the steering wheel. There is almost no comfortable position to place the seat and steering wheel for someone of my height 6ft where the speedometer is visible. Please make Hyundai move the speedometer to the middle of the screen (not outside edges where it is blocked by the steering wheel)!! I have contacted them and they have essentially gaslit/ignored me about this.

POWER TRAIN, ELECTRICAL SYSTEM
Our all-electric AWD Hyundai Ioniq 5 has an issue where the rear motor electric oil pump (EOP) overheats and ceases to function when the problem occurs, which disables the rear motor and effectively causes the car to become a front-wheel drive vehicle with a "hesitation" in the acceleration. This problem only occurs after a long time of high-speed driving and typically on a warm day (upwards of 70-80 degrees F). When the problem occurs, the rear motor ceases to function at all and only the front motor operates to power the vehicle forward. The acceleration is also impacted, such that when the accelerator is pushed, the car "hesitates" for 1-3 seconds before the front motor takes over the demand for power and "lurches" the car forward in a jerky motion. The symptom will last as long as the car is in an overheated state. However, if you pull the car over and let it rest for a period of time (undetermined), the rear motor will again operate normally until it overheats again. For us, this occurred once on a very hot day traveling approximately 50-60 miles on interstate travelling at speeds over 70 MPH. On another occurrence, it happened after driving the car about 200 miles (stopping for a lunch break in the middle), for about 4 hours. When this problem occurs in other cars equipped with RWD only, they lose all forward power in the car and coast to a stop even when the battery still has a charge. We've taken it to our local dealership for repair on Sept 12, 2024 (McGee Hyundai of Barre, VT) and they claim that there is nothing wrong with the vehicle. After researching the topic, I've determined it is the failing rear EOP must be replaced [XXX] and [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

WHEELS, SUSPENSION
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.

TIRES
On [XXX], while driving north on [XXX] to Michigan, I stopped in Carmel, IN to charge my 2023 Hyundai Ioniq 5 SE RWD vehicle. After charging, I reached 45mph and immediately experienced violent shaking of the steering wheel and seats. The vehicle was immediately driven to Hyundai of Carmel for inspection and possible maintenance. A service technician drove the vehicle and experienced the issue, but could not recommend a solution. The vehicle was driven back to Louisville, KY (home location) and taken to a Tire Discounters the following morning. At Tire Discounters, a technician drove the vehicle and experienced the same behavior, but could not provide a solution. Numerous trips to multiple Hyundai dealership service departments and tire service centers (Big-O-Tires and Tire Discounters) resulted in no solutions. After extensive research, a potential solution was identified by the vehicle owner relating to the noise-isolating foam located on the inside wall of the tires. There are numerous reviews on Michelin's website documenting this specific issue with the tires. A call to Michelin costumer service successfully concluded with a warranty claims number. However, none of the previously mentioned tire service locations would investigate because the vehicle only had 6,400 miles and the Hyundai dealership service departments refused to address the problem. Ultimately, Pep Boys accepted the Michelin warranty claim and found that three of four tires (Michelin Primacy 235/55R19 101H) that came as part of the original vehicle purchase had the internal isolation foam disconnect from the tire belt and gather in a central location inside the tire. There has been no evidence of notices or information from Michelin to dealerships or service departments regarding this issue and the potential for dangerous driving conditions or damage.

The recall stated in this report says that it was incomplete, however the recall was completed by the Hyundai Dealership, the software updates were installed and the ICCU failed anyway. When the unit failed the car went into "Turtle Mode", only able to go a max of 25 mph, and the 12 volt battery drained and died.
