Have a business associate who was debating between a 2015 and a 2016 model, while both were being sold by Apple. I've been meaning to tell him just how much he dodged a bullet, by going with the 2015. P.S. I see now, this problem pre-dates the 2016 models. Still think -- keyboard failures, etc. -- he dodged a bullet. But this behavior -- well, it would freak me out a little.
