Well I'll start--I have an '03 YXL with close to 15K miles on the clock, bought new in Dec. 2002; just about every morning within a minute or two after startup (and still in idle/park) I hear the knocking noise (definitely isn't a pinging noise as I can distinguish between the two, unfortunately--rather not have to hear either one on any of my vehicles, quite frankly). FWIW I believe I first noticed the knocking around the 12K mark; in any case, there is definitely some knocking (not excessively loud but clearly audible at idle) shortly after startup, and definitely after every cold startup.
Fixed after '02? If my FSC is any indication, GM apparently didn't do a thorough job of doing so.
