My car would no longer charge after testing various chargers at home and different public charging stations. If this had happened away from home, and without cell service, I might have been stranded. I took I into the Hyundai service center, and they said the ICCU had failed. They replaced if after waiting a week for the part.

Vehicle: 2026 Hyundai Ioniq 5 Description of Safety Defect:The Reverse Parking Collision-Avoidance Assist (PCA-R) system exhibits a severe software logic flaw that creates an immediate traffic hazard. When a standard, hitch-mounted bike rack is installed, the vehicle’s rear sensors detect the rack as an imminent collision obstacle while in reverse. The system responds by executing an abrupt, violent emergency brake application, bringing the vehicle to an unexpected dead stop. The primary safety failure is a lack of non-volatile memory retention for driver settings. In the infotainment system under "Parking Safety," a driver can manually deselect or disable the "Rear Safety" automatic braking feature to accommodate hitch accessories. However, this setting completely resets to "Enabled" by default every single time the vehicle is restarted. Safety Risk & Real-World Consequences:This defect has caused multiple documented near-miss incidents. Specifically, when attempting to reverse off a main roadway into a driveway with cross-traffic present, the vehicle suddenly slams on the brakes due to the bike rack. This leaves the vehicle unexpectedly stranded and protruding into active lanes of traffic, nearly causing severe rear-end and T-bone collisions with passing vehicles. Requested Corrective Action: Hyundai must issue a software update changing the ADAS memory logic. The Reverse Parking Collision-Avoidance Assist state should persist in the exact state it was in when the vehicle was last turned off (Last-Mode Memory). If a driver explicitly disables the feature to safely operate a bike rack or hitch accessory, it must remain disabled until the driver intentionally re-enables it.

I am a tall driver (6'4") and I need to wear sunglasses when driving most of the time. The eye tracking device seems generally incompatible with both of these conditions. When the eye tracker fails to recognize my eyes are looking at road it disables driver assist features such as lane centering which can occur unexpectedly and has almost caused me to wreck once. I have tried without sunglasses and squinting at the glare also causes the system to fail. I often have to lift my glasses and stare at the sensor to make the warning go away (in effect forcing me to take my eyes off the road. If sunlight hits it, it also fails. So in summary, this device does not work in the daytime. I have contacted the dealer, and they basically read the Hyundai response I've found online verbatim: summarized, you can't wear sunglasses, prescription glasses, be over 6 foot tall and several other conditions and expect the system to work. There is no way to disable the tracker. There is an option the dealer pointed to, but it is ignored when you turn on any of the assist features. Since this system is currently so unreliable, at best, this is an expensive feature I am unable to use. At worst, the distractions it is causing is going to cause an accident. This is an ongoing issue, date indicates first time issue was noticed.

On April 12, 2026, I was using the parallel parking assist feature on my 2026 Hyundai Ioniq 5 Limited AWD. I was parking on perfectly level ground with a parked vehicle behind the empty space I was attempting to enter. During the maneuver, the collision sensors activated, but the vehicle continued accelerating toward the parked car. I had to press the brake to stop the vehicle and avoid a collision. This created a safety concern because the system appeared to continue the maneuver despite the active collision warnings.

I am writing to report a serious safety concern regarding the “Consider Taking a Break” driver alert system in my new 2026 Hyundai Ioniq 5 Limited, which currently has 515 miles. This notification is presenting itself in a way that I believe creates a distraction and potential hazard while driving. The alert appears frequently and without clear justification, even when I am fully alert and in control of the vehicle. Rather than enhancing safety, it draws unnecessary attention away from the road and contributes to driver frustration. From a safety standpoint, any system that interrupts driver focus—especially without accurate or consistent triggering criteria—can increase risk rather than reduce it. This is particularly concerning in real-world driving conditions where attention needs to remain uninterrupted. Due to this issue, I am seriously considering returning the vehicle, as I do not feel confident in a system that behaves unpredictably and may compromise safety. I strongly urge Hyundai to: - Investigate this behavior immediately - Issue a recall or software update to correct it - Provide owners with the ability to disable or customize this alert I have also included NHTSA on this email, as I believe this warrants broader review as a potential safety defect. Please advise on next steps and whether a fix is currently in development. Thank you for your prompt attention to this matter. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The wiring for the air bag system under the driver's seat is exposed and unprotected which has led to disconnection and or damage to the wiring harness which then results in a disabled air bag system. This is a manufacturer design flaw and a serious safety issue. Other owners who have experienced damage to their wiring harness here have had disabled air bag systems for prolonged periods and costly repairs that Hyundai had refused to cover under warranty despite the fact that it is an obvious design flaw and a serious safety issue. See attached photos for evidence of how exposed this wiring harness is and suscebtible to damage as well as an example of damage which can occur which other owners have reported. Damage to this unit due to poor design results in compromised driver and passenger safety and extremely costly repairs ($10,000) which it appears Hyundai is refusing to cover under warranty. We request that this be recalled in order replace the design so this wiring harness is protected properly.

Upon delivery of a brand new 2026 Hyundai Ioniq 5 with 13 miles on the odometer, the washer fluid warning illuminated the next day. Reservoir was refilled on 3/29 and was completely empty by 3/30. Vehicle was brought to the authorized dealer on 3/31. The technician confirmed via repair order that the washer fluid hose was actively spouting directly above the ICCU — Integrated Charging Control Unit — a safety-critical high voltage component. Washer fluid was confirmed present in the ICCU floor pan. The cause was a nail severing the washer fluid line. The dealer confirmed the vehicle sat on their lot approximately 70 days before the 3/23/26 delivery date and that washer fluid is factory pre-filled. This indicates the leak was active for approximately 70 days before delivery, during which washer fluid leaked above the ICCU and surrounding electronics. Repair required complete interior disassembly — seats, carpet, center console, floor trim — on a 156-mile brand new vehicle. A full floor wire harness was replaced under Hyundai Techline authorization. Soaked carpet and insulation were salvaged outside rather than replaced. Hyundai Motor America declined to proactively replace the ICCU despite documented fluid exposure above it and denied an extended warranty request covering affected electronics. Safety concern: internal corrosion from extended fluid exposure may not present immediately but can cause sudden loss of drive power — a known ICCU failure mode on this platform subject to multiple prior recalls. Loss of drive power at highway speed poses serious safety risk.

While driving at highway speeds (approximately 70 MPH) with the vehicle's Assistive Driving functions engaged, the Driver Monitoring System (DMS) malfunctioned. Despite maintaining constant visual attention on the road ahead, the system issued repeated, erroneous audio warnings claiming driver inattention. I attempted to adjust my head and eye position to satisfy the sensors, but the system failed to register my compliance and continued to cycle through warnings. ​Consequently, the vehicle initiated an unwarranted "fail-safe" maneuver and suddenly applied the brakes while traveling in the flow of traffic. This uncommanded, rapid deceleration created an immediate and severe risk of a high-speed rear-end collision with following vehicles. The failure appears to be a false-positive defect in the eye-tracking software logic and its integration with the braking system. The vehicle is available for inspection to analyze the system data logs.
