After roughly 750-ish (I filled up a couple of times, roughly. 1-3, I don't remember, but it has been since my last oil-change, and I have 1,000 miles to go until the next 3K mile oil-change interval (I run synthetic and usually go 4500) or something miles, the dealership says my Z1 rotors are trashed. They did a run-out dial indicator on them and they are horrible. The vibration shakes the whole car from stops as slow as 30mph.
They could not find any tq spec that was wrong, the entire front-end was taken down/re-tq'ed, what could affect the brakes. Nothing was out of spec.
They agree that neither the pads, nor the rotors show signs of hard use other than being severely warped (no blue spots on the rotors, no excessive brake dust, etc.).
The calipers were all checked and function fine.
Nissan Corporate is getting involved.
I'm going to ask that either they show me what is causing this issue (produce the defective part for me to see, or educate me to the tq-spec, whatever, that is off, if any can be found), or give me pay-off and take their POS and let me go on my way.
I can see no other resolution other than them turning or replacing my rotors every 500-1K miles. I drive the car 26 miles a day to work and home, 3-4 days a week. The other 3-4 days, it goes 20 miles a day just to the gym. Plus road-trips. Now that it is vibrating so horribly, I am aware each and every time I am on the brakes. I use them less than I thought even before. This is horrible performance for a car which has a whole page in the product literature devoted to the Sport brakes, and which features multiple pictures taken on what is obviously a track of some sort.
I have not heard back from Corporate, so thus far, all of my dealings are positive. The Nissan dealer says there simply is nothing at all they can do except replace the rotors/pads for me, and that's obviously not the issue.
Here are the rotors I trashed in a month of home/work/gym in the flatlands of NW Louisiana:
