Owner report 11649366 · 2025-03-19 (March 19, 2025)
These cars still have problems keeping the 12v charged. Car was leased on Jan 19. 12v first died on Feb 15, took it to dealer where they trickle charged it. 12v died again on Feb 18, dealer replaced the 12v. The 12v died again on Mar 11 and is still at dealer service center. Case with Hyundai corporate was opened and the dealer is going back and forth with them. When car is left alone for 5 days, the 12v appears as needing a replacement, so there is something wrong with the system that keeps the 12v charged or there is some parasitic drain some…

Owner report 11665855 · 2025-06-09 (June 9, 2025)
The high-voltage traction battery on my 2025 Hyundai Ioniq 5 Limited RWD failed unexpectedly around [XXX], when the vehicle had approximately 1,250 miles on it and was just over 3 months old. The car had been parked in my driveway with about 80% charge while I was away for several days. When I attempted to drive it, the vehicle would not shift out of neutral. No warning lamps or error messages were displayed before the failure. The vehicle was towed to Van Hyundai in Carrollton, TX on April 3. While loading it onto the tow truck, the 12V batte…

Owner report 11652207 · 2025-04-02 (April 2, 2025)
The Forward Attention Warning system in the refreshed 2025 Ioniq 5 gives constant false positives for both my wife and myself when we are driving the car. With Hyundai's HDA and lane keep active, the system keeps chiming, claiming that the driver is not looking at the road when we are. In fact, the calibration is so poor that it is a safety issue. The constant random warnings are very distracting, and sometimes the system does not recapture your eyes before timing out and hard braking the car on the highway. This is really unacceptable and …

Owner report 11652606 · 2025-04-03 (April 3, 2025)
I purchased this vehicle on [XXX] in the state of Colorado and had to drive it home through a winter storm to California. While driving home the vehicle on multiple occasion the vehicle flagged driver assist disabled or inoperable errors due to "radar blocked" stopping and checking the front of the vehicle I found that the car had no snow or ice build up on the exterior of the bumper, and there was no reason that all the driver assist and even safety features like Automatic Emergency Braking had been disabled. In addition while making this dr…

Owner report 11682451 · 2025-08-22 (August 22, 2025)
The Driver Attention warning activates almost every 5 minutes. No glasses are involved. I have tried many different steering wheel positions. There are plenty of other 2025 IONIQ 5 owners with the same issues as seen on forums. There is a setting to turn it off but it does not turn it off.

Owner report 11699543 · 2025-11-15 (November 15, 2025)
I was driving to work on the morning of Nov. 12th, 2025 in East Greenwich RI. The car had been fully charged on my home Level 2 charger the night before. It was a chilly morning so I turned on the heated driver seat and steering wheel. Less than a mile from my house, and without any warning or prior issues, I heard a loud pop from underneath the vehicle. Immediately the car displayed an error on the dash reporting electrical system issues. The car still seemed driveable so I began to drive back home, noting that the car wouldn't exceed ~30 mph…

Owner report 11666613 · 2025-06-12 (June 12, 2025)
1. The Integrated Charging Control Unit (ICCU) and associated high-voltage harness/fuse appear to have failed. According to the dealership, both the ICCU harness and a high-voltage fuse are being replaced. The vehicle is still at the dealer for repairs and can be made available for inspection upon request. 2. While merging onto a freeway on-ramp after charging at a Tesla Supercharger in Barstow, California, the vehicle suddenly stalled, losing all propulsion power. This occurred in live traffic while attempting to accelerate, putting me at sign…

On January 1st, while driving on a highway, my vehicle experienced a sudden electrical/battery system failure.

The vehicle was unable to maintain safe highway speed, putting me and other drivers at serious risk of an accident. Hyundai Roadside Assistance failed at the time of the incident, as the mobile app did not work. I was forced…

Owner report 11714038 · 2026-01-28 (January 28, 2026)
On Friday evening, my 2025 Hyundai Ioniq 5 was parked at a ferry terminal in central NJ in cold (~32°F), windy conditions near water. At approximately 6:20pm, I remotely activated climate control using the MyHyundai app. When I entered the vehicle around 6:25pm and attempted to start it, the dashboard immediately displayed “Stop vehicle and check power supply” and “Check electrical vehicle system.” The MyHyundai app reported diagnostic code PIA9096, which is widely reported by other owners as an ICCU failure. The vehicle became completely inop…
