FWIW, their reply to my email on the matter is below. I thought no harm in asking for a recall or tsb -- after all they can just say "no".
Anywho...

comments : I understand that the 2012 370Z models will be equipped with oil coolers standard. That's great for new customers, as this motor has a persistent problem with running at higher than ideal oil temps, even in normal driving conditions. Nissan needs to make the oil cooler available to owners who bought their car 2009-2011 (at minimum to those who are still under their drivetrain warranty). The oil cooler should be offered either as part of a recall or TSB, with the parts and labor either waived or greatly discounted, and protected under the customer�s remaining drivetrain warranty. You will be hearing similar suggestions from thousands of owners -- take this seriously and do what is right for your loyal customers.
