I, too, have a 2016 Touring. Although I haven't had Fob problems like you, I did experience battery problems. Ironically, I just had my car inspected and was told/shown that the CCAs on my battery were "marginal" but acceptable. The next week my battery died. Fortunately, I had been proactive and had gone to CostCo for a replacement battery which was still in the cargo area (it had been too cold to replace it). Needless to say, i "braved" the cold. Long story short, get a new battery. I don't know if it will affect your Fob problems or not, but it couldn't hurt.
