I think you are looking for this thread:

I have never gotten a response back from Nissan Canada regarding this issue. The dealer was offering to do a service similar to yours, however I felt it did not solve the underlying issue. I have done what others have on this forum:
Apply a 1" wide strip of clear paint protection film (clear bra), to the lower door sill where the wear occurs.
BTW, I have added the above thread to the FAQ as it had gotten lost.
