Once in a while I've seen a batch of very strange keywords in a GA report - and not just in January. I don't think those were a GA issue. In cases where I can access the raw server logs, I do see that keyword traffic. So it's more likely to be a very strange ranking problem in Google itself. The SERPs can get mighty strange at times!
