I don't think anything is wrong with your taillights; there is really nothing mechanically that could break in the tail assembly to cause an error, maybe rust or corrosion but not in a fairly new model car - and you would physically see that.

In November 2015, they revised the F22 tail light assembly harness and added an additional ground wire. Anyone doing the LCI replacement can confirm this, just do a search. The ground wire is what I suspect that is your problem. I would buy the revised cable first, I'm positive that will solve your issue.
