None of those apply to me, and I own a 370z. I also owned a 350z for 5 years. I have plenty of criticisms for the 370z (more so than I did for my 350z).
#1.The shifter vibrates and makes a very loud buzzing noise at high RPM.
~Is your shifter 100% stock?
#2.The suspension is not very compliant with road imperfections.
~Nor was any other sports car I drove with similar suspension. Sports car....
#3.The driver seat was made for fatass americans and moves side to side and clicks.
~You are not alone,

#4.The side view mirrors are a complete failure/design flaw. Huge blind spots on both sides, even with the mirrors angled out 100%.
~My mirrors are perfect, yes they are a bit large but no blind spots after you spend a good amount of time adjusting them. Not saying you have not spent the time, but the only blind spot I deal with is when backing out of a parking spot (which I avoid doing).
#5.The rear hatch sticks and you have to push the release button repeatedly.
~Quick search,

#6.Having to push on the paint to get the gas door open.
~Yes it sucks, but if it bothers you that much then wear gloves. Because you have to touch the door handle to open your car, touch the paint to open the back hatch (mostly).
