On another note, my wife's Avenger as the 3.6L and my father's RAM crew cab 4x4 has it. Neither have had a single issue. Both engines are quieter than the JK's at idle. Maybe is has something to do with the engine bay, and chassis design but the 3.6L in the JK is louder and has more vibrations that in both of the other vehicles at idle. Also, my father's RAM runs better than the JK and gets 5mpg better on the highway despite the fact it is a much larger vehicle, hahaha.
