I bought a 2002 Escalade certified, and have an appointment w/ dealer Monday the 14th and I want to make sure there isnt anything else I should ask while I have it under warranty? Here are a few things that I'm noticing. Hesitant idle w/AC on, small grinding noise on driver front wheel when going down hill on turns w/o brake depressed, Seems to be a rougher ride as the miles add up, door squeek rear passanger side.

If anybody has other things that are known to go wrong at this many miles please feel free to add in.
