sounds like you got one of the Zs with EVERY common problem the early 350Zs had.
1) you shouldn't have bought a 350z with the tire feathering problem.
2) yes, it's common. the hatch struts just aren't strong enough. you have to click the open button and pull up or change out the struts for stronger ones.
3) i've heard of this happening too. not sure what the fix is though.
4) does it have the nav? if so, the door automatically opens when you turn the car on, but the door motors are known to go bad. costs $700 to replace. if you don't have the nav then i'm clueless on this one.
Pretty soon you'll need to change out the window motors.
