John,
Sorry it's taken me a bit. Just to let you know I took the Murano into the dealer. I had them write up a repair order and submit to corporate for a goodwill (Nissan covers it under warranty).
They denied it, so the next step is to deal with Nissan Consumer Affairs (1-800-NISSAN-1). The are currently investigating the TSB, and they'll make a decision by Friday.
Recall are issued by NHTSA, not Nissan, so if Consumer Affairs does not approve the repair, I will file a recall complaint with NHTSA.
You should too. The link is

In the mean time, another option since you mentioned ebay, is to replace the entire seat. Ebay is going to be a tough find. There's a website car-parts.com which links up salvage yards from across the country. There are entire seat assemblies out there from $150 and up.
Since mine is tan, I have 3 right now that I'm looking at (leather, ten, power, gas pedal button, side air bag) that are identical.
Here is the link to the current search for our 2005's.

There's a few black ones on there, and every single one that I called were able to provide me with pictures via email with in a few hours.
But definitely, file a recall complaint, that's the only way we're going to get this resolved.
