Just bought a new 2008 Cayenne over the weekend. It's the Crystal Silver, tiptronic S, Bi-Xenon Headlights w/washers (awesome lighting), 18" Cayenne Turbo Wheels, black interior leather just to name a few options. Only 1 problem so far and not sure why the sales guy did not have the shop look at it before we got there. The rear 5th door that you can automatically raise with the touch of the keypad raises just fine, but when I hit the button on the back to lower, it does go down, tries to latch and shut, but just kicks back open, like its not quite catching the latch or there is too much vacuum inside the cab for it to close. The salesman pointed this out that it did it to him once and tried it a few more times and did not do it again. We went shopping right after the purchase and when closing the back after putting our shopping away it did not close. WHY oh WHY did he not have it looked at before we got there.[:@]
