2012 Rubicon Unlimited

I heard that the 2012 engine was having head problems. Has anyone experienced this and what was the dealer reaction/response. Appreciate hearing back.

Ive stopped following the head threads but as it seems to me the majority of the problems have been with heads produced during a certain time frame in late 2011. Sounds like a bad batch of heads??? I could be wrong but I dont want to worry about it if it isnt happening to me. Id go crazy constantly worrying. Ive got 1300 miles on my 2012 JKUR (produced mid march 2012) and it purrs beautifully and quietly. Go for the 2012!!..... Thats what the 100,000 mile powertrain warranty is for.

They are uncomfortable, ride like crap, and catch fire.

The Pentastar is significantly better than the prior generation. A few minor growing pains, but every mfg runs into those.
