My (Unfortunate) experience with Samsung service.

My 60mm squeks few months back, to be exact like 3 months after my purchase. Everything works fine, AF hunting seems normal like before. I'm staying in all year round warm country, so the cold is not a factor to be considered. But I myself however, permanently store the lens and bodies in an electric dry cabinet all the time when I'm not using it. And until now after 6 mths of squeking, nothing breaks... (yet)

Strangely the squeks go away after several mins of playing with the AF, probably loosens up the internal mechanism a lil...

If not mistaken the 60mm and 85mm are both SSA's.
