I recently purchased a new
I recently purchased a new 2014 Jeep Rubicon X with the Pentstar motor. With only 5000 miles on it the check engine light has come on several times so I decided to check the code and it was for "Cylinder 3 miss-fire". Is anyone aware if this cylinder head issue has not been corrected on the 2014 Pentstar engines? I find it hard to believe, after reading these posts, that Dodge has not fitted the newer engines with this up-graded cylinder head. Any information would be helpful so I'm prepared to deal with the Jeep service dept. Thanks!!!
