Yes, this has been a known issue. I'm not going to post this as an answer, as I can't remember where I read about it, and thus can't include references, but it has been discussed in a number of LEGO fan forums.

I have found that the clear pieces depend on the piece. Some of the thinner ones do yellow, but I have 2x4 Clear bricks that are not yellowed. I think it depends on the thickness of the ABS that was used.
