On Nov.18,2021 while driving my 2015 dodge journey suddenly felt like something slammed into the back of my driver seat, and into the back of my head. Come to find out my headrest airbag deployed. I feel this should be repaired at the expense of manufacturer. It is a defect that can cause injury to driver. I was not in an accident was just driving down the road. I have had pain in my neck and head since this occured.
