So check engine light came back on ... Bringing it back for third time for same issue!!!! I'm
Getting annoyed now , 2012 with 13k on it. Anyone know the lemon laws regarding this issue?

 

It took three trips to the dealer for this problem for me too. They eventually changed the head out, but it took them awhile to come to that conclusion.

 

Go over to the Stock JK section. There is a thread called Pentastar Head Problems that has a ton of info. I won't go into detail but my 2012 went in for a bad cylinder head and was at the shop for 42 days! I was in a rental car the whole time and they covered it entirely.
