Intermittent P0302 code (cylinder 2 misfire) happening for last 2 months on the 3.6L pentastar engine. Never another code. Runs OK, occasionally rough at idle. Once heard a ticking from engine at idle, but not consistent. At 61,000 miles with no previous problem. Tends to code with warm engine.

Replaced spark plugs; same code within a week.
Switched ignition coils; same code that day.
Ran a bottle of seafoam in fuel; same code.

Thinking it might be the head or something else more serious. Thoughts?

Also, I am the second owner. Does the powertrain warranty transfer automatically from the original owner? Would this be covered?

Did you ever resolve this issue? I'm having the exact same problem.

 

The manufacturer powertarin warranty on Dodge Chrysler is 5 years 60,000 miles. The ticking sound is usually bad rocker arm which can wear the cam lobes if neglected your misfire could also be sign of a bad head # 2 cylinder is on the left bank which is the head that they had problems with in the early versions of the 3.6 L Pentastar engine. 2011-2013 3.6 L engines has an extended 10 years 150,000 miles powertrain warranty on the left head only issued by Dodge Chrysler.
