i found early on through research that along w/ the tire feathering issue, which was a recall, and if ure car wasn't serviced for it, u can do it. There's an issue w/ the tps..the second day i had my Z..it went into limp mode, and through research i found that it's a common issue in the nissan world...grinds n 5th, heard horrible stories about their trannys..but that comes w/ the territory..buying a sports car, so..gotta put some things in perspective.
