2023 HYUNDAI IONIQ 5 Complaints

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.

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.

The contact owns a 2023 Hyundai Ioniq 5. The contact stated while driving at an undisclosed speed, the vehicle lost motive power with several unknown warning lights illuminated. The vehicle was towed to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and a case was opened. The approximate failure mileage was 6,500. The VIN was not available.

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.

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)

Power limited message show when driving on highway then drop the speed and stop need to turn off the car and turn back on the everything back to normal. So scary

Battery will not stay charged, Car has to be jumped every time it's driven. Also sometimes the car turns off when it put in gear with a 12volt warning.

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.
