Had the same problem with my 03 350Z. The spring fix worked for a while, then the two penny trick worked for a while. Finally I just gave up on the hatch popping up on the first push.
I did solve the problem with my 370Z and I don't think I will have the problem in the future.
I got a Vert
no big heavy hatch...
