Seems there's a production error on Cobra Commander: the earliest ones produced were assembled with all his cords on the outside of the arm, instead of running underneath:
If you get one of those first 6,000 and don't like it, it's an easy fix. Simply warm the figure enough that you can pop the arm off at the bicep, reposition the cords the way they're meant to be, and put the arm back on. It'll probably take longer to heat up the water than to make the actual repair.
