I am prety sure this is not normal because I dont recall hearing this noise when I first bought this car. Basically when I drive the car for a while and park it up I hear a clicking noise that is very loud. I understand that this can be normal but is it normal for me to hear the same clicking noise when the car is started? My warranty is going to be up in another 1000miles so I wanted to confirm this with someone here before Infiniti tells me that its normal.

 

It sounds like it's just the expansion of all the metal components in your engine.
If that is the case this is perfectly normal.
The metal components will crack and creak when contracting and expanding.
You will hear this on almost all cars.
Your best bet would be to have a friend or family member you trust (and knows about cars) take a listen for themselves before taking it to the dealer.
Without hearing it in person there really is no way to diagnose the prob though
