Hi,
I don't know the Canon 80D camera, I shoot Nikon, however the symptoms you are describing of general strange erratic AF behaviour are similar to the issues I have had with Nikon DSLRs ..... often it's dust on the AF detector prisms under the mirror, remove the lens ..... (with the Nikon I go to clean sensor/raise mirror or the Canon equivalent in the menu) and then with the mirror in the raised position, use a rocket blower to blow off any dust which may have settled on the AF prisms under the mirror, it's a 5 minuet job which usually does the trick .
If you haven't a rocket blower they are cheap as chips on ebay and are very useful.
Certainly that would be my first port of call.
good luck ......
