Since the Z has only been out for a little over a year and a half the bulk of the predication must come from general Nissan reliability.

The "Initial Quality" or IQ ratings are based on how many "issues" are reported by consumers for that vehicle type during the first 90 days of ownership. It's only based on whatever strange reason a person may bring their car to the dealership (you've seen the threads on this forum...), and doesn't account for any by-design behavior or if there is a true defect. Also, I don't believe there is any weight to severity. The hatch spring issue a lot of people had was incredibly minor, and would impact reliability ratings just as much as melting electronics.
