Nismo Z factory paint defect

Pariz

My nismo has a crack paint and crack rear bumper under the wheels, ten hrs after receiving the car I reported the defect to the dealer. This is a very ovious factory problem and Nissan it's not taking care of the problem. Months have passed and now they are saying that I cracked the paint and plastic.
I am thinking about getting a lawyer and will help if someone else has the same problem.
I am very dissapointed with Nissan.
I don't feel safe on this car now, I also hear crackling noyse when I am driving it.
