Ok, I posted a help thread about a week ago about my G37 Coupe Journey not being able to shut off, nor will these other features function properly: Headlights, windshield wipers, trunk release, signal lights. I couldn't even do an emergency shut off. Luckily I found something online to help me out: http://www.justanswer.com/nissan-inf...-turn-off.html

That link showed me how to stall my car and restart it. My question is, before I go to the dealership to ask about the issue, what would be the cause of this malfunction?

Thanks.
