You have the same material I have in mine. I haven't seen your problem yet because with 29,000 I have replaced the driver's side bottom 4 times and the passenger 3 times and passenger rear once, due to the seat material coming apart. Haven't had time for the material to come loose like yours.
The problem that you, like mine, will have, is if you look closely at the horizontal thread, it looks like fishing line. That will seperate from the dark material that the back of your thighs rest against. So you will end up with "fishing line" material sticking out.
I have tried to convince Nissan that they have a problem with the material. They have replaced the seats with the warranty, they have to do that. What I am concerned about is, what's going to happen after 36,000? Since I have evidence that this is a material defective, (over 3 replacements for me and over 30 people on this site have the same problem), Nissan needs to either extend the warranty or replace the material with new. I have requested to speak to a supervisor on the Nissan customer service line since February 05 and none have called. I was told that one would call within 24 hours, but after 5 calls I believe I am just #!$$!%* in the wind. The dealer sales department told me that is pretty standard. If the super either doesn't want to talk to the customer or doesn't want to get involved they will not call back. After all what is the customer going to do, turn Nissan in to themselves!
Good luck with your problem. Keep a close I on the "fishing line" problem. That stuff will stick you in the leg. Some people are cutting the loose ends off or melting with a lighter. Not me, $30,000 rig should need no sissors or a lighter to repair the obvious!
