I just had a fair amount of service done at my indy shop:

Oil change
Replaced idler pulley and belt tensioner (they were squeaking)
New passenger side tail light assembly (kept getting a "check brake lights" message - turns out the contacts had gotten fried)
Transmission software update to resolve the harsh 1st/2nd shift
Re-flush the brake fluid to get rid of some sponginess

ETA: Oh yeah - and I installed a cargo cover which I just bought from another member.
