What I understand is that Nissan was not honoring the warrenty on the transmission because using the launch control requires turning off the VDC, which apparently voids the warrenty.
Basically, Nissan designed in a self-destruct feature, and cleverly disguised it as a perfromance feature, which could only be used by voiding the warrenty. Pretty cool feature on a 100K "super" car if you ask me

.
Kind of reminds me of Subaru includeing an SCCA membership with the WRX STI, and then voiding your warrenty if you used the car at an SCCA sactioned event
