SOURCE: auto focus problem
My first suggestion is to send it back if it is under warranty.
The grease probably got so thick, from the cold, that it caused too much resistance for the auto-focusing mechanism. You probably have damaged the focusing mechanism in the lens. You cannot repair this, yourself. I don't know how cold is too cold but it really shouldn't have done that.... Tamron makes cheap lenses. Try and exchange it for at least a Sigma.

Hey shutterbug72,
According to the manufacturer the first thing you should try is cleaning the lens contacts with an eraser. If that doesn't work you could try removing the battery and reinserting it to reset the camera. It seems to me that if there was a compatibility issue going on you should have seen that from the start. As far as what lens you should buy both Tamron and Canon make very good lenses, but with Canon lenses you shouldn't ever have compatibility issues. I hope this helps!
Sincerely,
Allan

Sorry but if you've tried all the usual fixes then there's nothing more that you can do. Either pay for a professional repair or continue to use the lens manually.
A professional repairer should be able to indicate what the likely costs are going to be and you can then judge whether repairs are cost effective.
Personally, I'd stick to manual focus as I've always preferred knowing exactly what I'm focussing on instead of constantly fiddling with buttons and menus to override what the dumb camera has locked onto.

Try cleaning the contacts on the camera and the lens, this is what usually prevents AF from working correctly.
