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 exit — all without being able to accelerate. This has happened to both of us as drivers, both alone and together, and both with the adaptive cruise control feature enabled and without it enabled. We have taken it to our …

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.

I briefly turned off the vehicle while a passenger loaded …

The vehicle will not turn off. I returned it to the Dealer, Oakland Hyundai, and their service department has had the vehicle since 7/27/26. When I brought the vehicle in to service it had 2,519 miles. Service rep has advised that technicians are trying to find the faulty part and have been unsuccessful to date. A technician from another location is scheduled to see the vehicle during the week of 8/31/26. I have filed a case with Hyundai America and will send a demand for restitution on 8/28/26. I view this situation as a clear safety issue - the car will not turn off.

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.
