Went to dealer today to change oil and spoke about the front seat movement issue. They have heard about it and I presented them with a part number that was posted on this site for possible solution. Well they told me that the part number was a complete seat frame for $1500.00 and that if I wanted they would replace it but do not see why I would just put back on what will be taking off. Anyway, they call Nissan tech. and they advised them that they are very much aware of the issue and that there will be a kit coming out to fix it as soon as the kit is "confirmed" (I believe that's the word he used). My service dealer (also friend) said that relates to around a month or so before it is posted. He told me by the time I go for my next oil change, they should be able to address the moving seat issue. Just thought I would pass along the info!!!!!
Take it for what its worth.
