When I am driving/turning at any speed I do not hear anything or feel any weird vibration. I am not exactly sure what the problem is, I have done some research about KW's and there are cases with knocking issues. Has anyone here experienced this problem? I am going to try and take my car to the shop this weekend to get it looked at.
Have you checked that the rear upper mounts are snug?

There have been many reports of internal noise with the KW's, but your noise seem to be the upper mounts if you can easily duplicated with the vehicle at rest.
