I haven't worked on a motor in years. My 2011 looks to have a small trail of oil coming from what, judging by the location, looks like a cam position sensor. Does the 3.8 have one. It's located on the top center of the motor towards the front.
I wouldnt worry about it - thats what warranty is for
To be honest this is the first vehicle I have owned that I havent even really had a good look over the motor yet!
