Thought I would share this info.  I searched this forum for my issue and found nothing, so this may help some 2012+ owners.  I own a 2012 Jk Sport with around 14,500 miles. I have been experiencing a strange squeak coming from my motor for about two weeks that I figured would be the belt, a pulley, or the water pump.  Did a bit of research and found that several owners have been experiencing the same or similar issue.  Here is a video of the exact sound I am having.  It turns out it is the water pump failing already.

Others with a similar sound have had an issue with the pcv valve. It has taken the dealer several trips to diagnose the issue for some owners. One guy had 8 trips...lol They basically replaced all of the pulleys, the tensioner, the belt, etc. Hopefully this save some owners the trouble of dealing with a service department throwing parts at it. The big issue for me is that the damn part is on nat'l backorder. Don't know when I can get it. The service department called me and said to come get my rig and they would call me when the part is in. I will update once I get more info. Hopefully this helps some of you.
