This might be interesting to any who have 2005 PF's but haven't upgraded the rear door latch cover to the new type. When the 05's came out the rear door latch cover was poorly designed and vibration of the cover would eventually wear the paint, expose the metal and then rusting would occur seen as streaks of rust down from the latch cover and around the licence plate area on some of the PF's. The door rust repair and replacement with the redesigned latch cover are covered in TSB 05091, although I don't see that number in the service bulletin list.
Talking with the local service department they tell me that 2006's and later don't have this problem as the redesigned cover was factory installed from then on, but 06+ owners should watch that area for rust problems anyway and that on the 2005's rust often doesn't start showing until after a couple of years.
a NissanHelp thread that discusses some of the problem.
