It sounds as if you are having a battery problem. You need to have the battery checked at an Infinity Dealer. The battery should have warranty on it (pro rated) with such a new vehicle. Hope this helps.

verify that you have a fully charge battery and that you have the same amount of voltage at the battery as at the starter when the key is turned to the start position. If not repair fault at positive cable either at battery or at starter. If voltage checks good. Use a remote starter and turn key to the on position and try to crank over engine with remote starter. if engine cranks over. You have a defective starter solenoid and starter must be replaced.

Had the similar problem last night with our 2005 Infiniti QX56. After a day of normal driving and performance, the car would crank and crank like normal, but would not fire and seemed like maybe the fuel pump was out. My wife and I tried several things and then resorted to calling the Dave Baldwin from Best Deal Auto Sales of Auburn, Indiana and he had me go out and perform the following sequence that I chuckled at as we went through the steps:
1) shut all doors unlocked
2) lock the car with the key from the outside of the vehicle
3) lock the vehicle with the fob by pressing the lock button
4) unlock the vehicle with the fob by pressing the unlock button
5) get in and start the car
To my amazement, it worked!!!!! It is only just over a week old vehicle for us and even with the 8 years+ of college, the Infiniti and Dave are each much smarter than us ;-) See if it works for you!!! I am not certain of how or why it worked, but Dave said that their is a securtiy feature that disables the fuel pump and will not allow intruders to start the QX56. He said the most common way to have this happen is in the summer when it is typical for someone to lock their car with the windows down and then unlocks the vehicle by pressing the unlock button from through the window...Although this was not the case with us, maybe it will provide some insight. So far no other forums I have been on has provided this as a solution.

You must use one of the factory keys.. A copy will not work. The key has a transponder that talks to the security system in the car and validates the proper key. If this is a factory key there is a problem with the pickup ring in the ignition or some other part of the drive authorization system (or whatever Nissan calls it) that the dealer will have to look at.
