Had the same problem on my 07. Smoked the fuse as soon as i replaced it....litterally, it smoked...lol. Was still under warranty so I let the dealer fix it. Told me the cig lighter had shorted out at the base. Replaced lighter and all has been fine for 2+ years. Its really not that difficult to replace, there is only one screw holding that entire center bezel, its located dead center in the back of the storage area next to the lighter.
