Bad cylinder head 2012 sahara unlimited

I have 2012 wrangler unlimited sahara with 16,764 miles. I brought it in with check engine light. Test said it was P0306 No.6 cylinder head misfire. They reset the code, gave it back to me and engine light came back on. Brought it back in and dealership now telling me a cracked cylinder head which needs replacing! They have had my Jeep now for 2 1/2 weeks because they say this part is backordered. Never a good sign. I always had ticking from the day I bought it and just never thought anything of it.
Do you guys know if there have been any problems once the head has been replaced? It will be three weeks this Fri since my Jeep has been with the dealership.

Consider yourself lucky it was seen within the warranty period. ALL 2012s have head issues but most will make it past the warranty period and leave the owner out of luck.

Our 2012 got a 7 year 70000 mile power train warrantee, I am not concern.

Huh?? If mine has issues after 100,000 I can live with that. Anytime before that, Jeep will fix it for free.

How do you know that ALL 2012's have head issues? Is your statement based on some inside knowledge from Jeep? Or one of the dozen or so "ticking Pentastar" threads. If every member of this forum had a "bad head" it would pale in comparison to how many 2012 Wranglers are on the road with no issues.

They received my head a couple days ago. They tell me my jeep should be ready for pick up today. Today is 3 weeks from the day I dropped it off.

not all have it.
25K & still going strong

I did just notice oil in the water of my old Mustang though

Do you think Ford will warrantee a head on a '68

Oh well. Maybe a pair of aluminum heads on the agenda

I just had mine done and they had the part in stock. It was only out of commission for a few days. Dropped it off Wednesday evening, had it back Monday afternoon. 2.5 weeks seems a bit much
