Crap I wish I read this thread before.
This just happened to my 2010 Nissan 370z Roadster yesterday.
Pulled the car in the driveway - went back inside the house for 15 min ... came back out to start my car and it wouldnt start. Saw the intelligent light key come on my dashboard - not knowing what it was I went and got my spare key and tried to start but with no luck.
Right now it is as the Nissan Dealership - had to get it towed there.... they said it will cost $1350 after taxes to fix
Honestly should this not be a manufacturer defect if we are ALL having the exact same issue??? I mean whats to say this wont happen again and again???
