I would still contact Thor directly (and your dealer if they are a good one) and politely explain you have been having the issue for several weeks and now it has gotten work and you are just passed warranty. There have been times when Thor has covered issues like this when the warranty expired a couple months prior to the event. It is worth a shot to see if they will cover it.
This is my fear with these full wall slides that are mechanical and not hydraulic. I just bought two of these Slide Locks so I could put one on each end of the slide when traveling.

There has to be an incredible amount of force on the motors and gears when going around bends. That can't be good for the gears and motor over the long run.
I read about a guy who would occasionally hear a "pop" when extending his slide after arriving at his destination. After installing slide locks, he stopped hearing that "popping" sound when extending the slides.
