Anyone have problems with newer Tahoes?

[Sub-versive]

I am asking for reference to questions my brother-in-law is asking. He bought a 2004 Tahoe new in August, it has about 10K miles on it now. It recently lost function of the cd player, then the "brights" aversion feature on the rearview mirror, the dash and interior lights would dim and flicker, and now his tranny is mis-shifting. The rig has a 5.3L and auto tranny(not sure of exact model).
I told him he obviously has some electrical issues(oooh my favorite!), he is taking it to the stealership tomorrow. I am wondering has anyone else had any issues or hiccups with their vehicles? Are there any recalls or TSB's that you guys/gals have knowledge of?
Thank you in advance.
