We turned 20K after our month long trip around the US a few months ago. The check engine light came on as we made it home, had the head replaced the following week. 90% of the miles has been camping, wheeling, and vacationing

The bad head was the only issue I've had with the Jeep.

It seems like just a matter of time before a 2012 Pentastar head has to be replaced. I hope the new head design fixes all this. My JK is much smoother with the new head.

I think it's almost always the left (drivers) side head that goes because they had a flaw in a large batch of them. Mine is a '13 jk and no problems yet, but I think was only the early 12s having this problem.
