Driver assistance
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. …
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. …
Speed control & acceleration
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. …
I am reporting a suspected safety defect involving inconsistent deceleration behavior in my 2026 Hyundai IONIQ 5. I regularly use Hyundai's i-PEDAL one-pedal-driving mode. In this mode, releasing the accelerator produces strong regenerative deceleration and can bring the vehicle to a stop. However, the vehicle does not retain this selected driving behavior after it is turned off and restarted. It reverts to a mode requiring substantially more use of the brake pedal. The behavior also changes in connection with shifting into reverse. In a Costco parking lot in [redacted], I stopped near the customer pickup area while using i-PEDAL. I briefly turned off the vehicle while a passenger loaded groceries. When I restarted and began moving, I expected the strong accelerator-release deceleration the vehicle had provided immediately before shutdown. …
