While the vehicle was stationary, the driver pressed a saved profile button on the Integrated Memory System (IMS) on the door panel to adjust the driver's seat. A passenger was seated directly behind the driver in the second row. Upon pressing the memory button, the motorized driver's seat began moving backward toward the saved position. Whether due to a system malfunction or a lack of built-in detection features, the vehicle did not interrupt the motorized movement upon encountering an obstruction. The seat forcefully and continuously compressed backward, squeezing and trapping the second-row passenger's legs. The seat did not stop on its own and only ceased moving when it completely jammed

On XXX, I experienced a safety-related problem with a rear door on my 2026 Hyundai IONIQ 9. While the vehicle was parked, I attempted to open the rear door from inside the vehicle, but the door would not open. The child lock was believed to be OFF at the time.
