Update: 8 days after towing my baby to the dealer.
No response from anyone at Nissan Consumer Affairs. I've been given 4 bad phone numbers/extensions for who to call. NCA says they can't reach anyone at the service dept, service department not calling me back. And each time NCA leaves a voicemail (because they like to call at 5:59pm PST) they say they'll follow up with me in 2 business days.
I've since dusted off my old 2001 Ford Focus (meaning I took it back from my dad lol). It's crap-tacular but it beats walking.
I thought of Lemon Lawing my car maybe to get all my money back (and close the loan on it) and using that money to patch up my Z32.
I thought about calling up the service dept and just telling them to go ahead with the diagnostic, hoping that the warranty will reimburse me - but they can't do anything until NCA gives a ruling.
Why does this have to be so difficult?
