If done correctly, it shouldn't ... but I can't speak for Nissan or Infiniti.

Just be careful not to short anything out. Meaning, I would (a) check all the mount locations you have in mind using a voltmeter to make sure that none of them are at battery voltage relative to the engine block and (b) disconnecting the battery at the terminals before you start and (c) making darn sure that you have tightened all bolts down - use locking metal washers preferably.
