I've had exactly the same issues with my 13" Mac Pro that I bought only 4 months ago. On 2 separate occasions the adapter wouldn't charge my Mac. During the first incident, only 3 weeks after the purchase, I just kept unplugging the adapter from the Mac and used different electrical outlets. Eventually it just started charging. I've never noticed my adapter getting really hot until sometime just last week. I plugged it into another surge protector ... after having spilled water onto the older surger protector ... and for some reason the adapater I'm using now will cause the adapter to get real hot. My nephew also reports that his adapter gets really, really hot ... like you said ... almost enough to cause a significant burn to the skin. My nephew, however, has never experienced the issue with the adapter not charging his unit.
