Well just a couple days ago my head rest decided it didn't want to stay flat anymore and decided to deploy the the SRS in the head rest. I have a 2010 KK with only 47,000 miles on it. It popped out while I was driving down the highway, luckily I was leaned forward at the time. As I look inside it appears that there was a bar that was held in my plastic and the plastic gave way. I have already scheduled a dealer service for tomorrow but I was just wondering if this has happened to anyone else before?
