2014 Jeep Grand Cherokee - Active Head Restraint

I have an event with the AHR ( active head restraint ) where it "automatically" activated? Was parked at coffee house in Palmdale, got in, turned on and "crack!!!". ( sounded like the center console fell shut ). Got out and could find nothing on the exterior. When I got back in the driver's seat I noticed my head hit the AHR. That's when I realized the AHR activated or opened up.

Took to the Reno Lithia Jeep dealer/service. They reset, and it activated. ( computer program confirmed no collision / bumping / etc ). Reno Lithia ordered replacement AHR. When part arrived, took my Jeep back in for this service. It tested fine at dealer, though only 4 days later, ( again parked at coffee house in Bishop, CA ((( maybe I am drinking too much coffee?? )) ) the AHR snapped open ( activated ). This time it did move my head forward as it should if I were in a rear-end collision. But I wasn't.

Took my Jeep back to Reno Lithia Jeep. The service department reviewed my retelling the events of my experience, had their tech mechanic retest, and the AHR continued to deploy. I was told that there is an issue, and that the main Jeep engineers would need to walk through the steps to determine why the AHR is deploying / activating. That was over 3 weeks ago, I am not so alarmed with Reno Lithia Jeep, but very concerned with corporate Jeep Chrysler customer service / engineer not being very responsive.

With that said, the Reno Lithia Jeep tech mechanic felt there was a short happening, because the activation would occur only when starting / turning on the ignition only - at least that is my experience - twice.

I don't want to turn off the electrical safety features, but if I could disconnect that AHR I would in a heart beat. I am not sure I understand how valuable the AHR is verses a head rest - but that is just me. BTW .... neither the colorful User Guide nor 600+ page Owners Manual (no listing in the index?? ) has any mention of the AHR. Another note, I learned about the AHR on these forums, with references and diagrams, which helped me to better understand. Thank you.

Attached photos for reference, especially those like me who discovered something / new feature which we knew nothing about.
