NHTSA Complaint #11701573 — 2015 DODGE DURANGO

The driver's side head rest deployed while I was driving on the highway without any collision and struck me in the back of the head hard. I did experience some whiplash symptoms for a few days as was confirmed by my chiropractor doctor. Post inspection revealed the plastic retaining brackets failed and the spring force released and deployed the headrest. I contacted Chrysler customer care (reference case #94643848) and was told my vehicle was just past the 10 year warranty period by 3 months and they would not cover the replacement cost. The replacement would be nice but what about the safety aspect? Why wasn't this a mandatory recall? Like the air bags issue years ago.
