Owner report 11714869 · 2026-02-01 (February 1, 2026)
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 sudde…

Owner report 11714591 · 2026-01-30 (January 30, 2026)
My BRAND NEW car is suffering an ICCU issue. I first noticed the screens going completely black while driving. I then noticed that I can’t charge at all on Lvl 1 and Lvl2 chargers (AC), but I went to the dealership and the helped me charge on lvl 3 DC fast charging. This is an incredibly dangerous problem, if this results in my 12V battery dying, I could be stranded while driving.

Owner report 11760015 · 2026-08-27 (August 27, 2026)
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 Cost…

Owner report 11759157 · 2026-08-24 (August 24, 2026)
While driving on the freeway with adaptive cruise control and lane keeping assistance on heading east into the morning sun my car suddenly attempted to veer strongly to the left as I exited the shadow of an overpass. I was able to stop the lane assist because I had a firm two handed grip on the steering wheel. Even with the firm grip and attentive driving I nearly left my lane as the wheels suddenly and strongly jerked to the left.
