2026 Hyundai Ioniq 5

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.

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.

Every 7 minutes of driving electrical failure , happens, which results in Check driver assistance system warning. Once vehicle is turned off, driving 7 minutes error pops again. Due to this all systems : Adaptive Cruise Control , Automatic Emergency Braking , Blind Spot Warning , Forward Collision Warning , Lane Departure Warning , Lane Keeping Assistance , Parking Collision Warning , Rear Cross Traffic Warning gets disabled. This creates a huge risk driving.
