Plastic is subject to material failure through temperature and normal fatigue of plastic materials. I have a fairly large box of computer 'parts" from a half dozen digital cameras made since 1999. All of them failed due to the plastic GEARS shedding their teeth and no repair parts are abailable.

Plastic gears in digital camera? You must be talking about motorized zoom lenses which are not in digital SLRs. So it's a non-issue for the OP's issue since he has a dSLR.

Plastics DO deteriorate over time, all of the plastic apparatus I have including chairs, kitchen appliances, automobile parts fail rather rapidly in the tropics either from temperature or humidity change but in fact plastic fails.

In those same humid conditions being outside, metal rusts when plastic won't.
