My 2007 was delivered in very late August 2007, and it still has intermitant steering wheel lowering issues, as well as the 6FL dropping to FM issue. It does not have the split screen PDC/rear camera view, so I'm very doubtful that it has the 27.1 update as described in that other thread....other than abysmal MPG, and a weird "low windsheild washer warning light (when it is totally filled), the trucks been pretty good so far.
On a good note, my R.E.S works fine so far, and my AC blows hard and cold , even with the rear climate on. Camera quality sux at night though...thought I heard someone post this has been improved recently as well...
