On August, 2nd around noon, I was driving alone, west on a rural road called 1869 in Liberty Hill, TX. I believe the speed limit on this winding rural road is 55mph, and I was about 1 mile west of 183. While my car was in motion, my active headrest activated (exploded) into the back of my head, throwing me forward into the steering wheel. This happened randomly and unprompted. There were no other cars on the road with me, I didnât collide with anything, and the road was smooth. I quickly regained control of the car and continued to my destination. The Hyundai dealership confirms the misfired active headrest, and Hyundai does not want to repair it, as the vehicle is out of warranty. There were no warnings prior to the event. I was resting my head on the headrest when it happened.
