   On June 6, 2026 (mileage 2500) I went to my garage to get the car to go to an appointment. I could not start the car. A battery icon flashed, in red, on the screen behind the steering wheel.

   Several times now (over 5), we have experienced issues where our car has briefly accelerated on its own and then either (a) braked hard on its own, too, or (b) the accelerator pedal stop working until we pull over, come to a complete stop, and either park or restart the car. We have experienced this multiple times on both surface streets and on highways. When this has happened on the highway, we've had to literally merge across multiple highway lanes so we can pull over or…

   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…

   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.
