They replaced both cam phasers, cam gear and both camshafts on the left head. They found flat spots on the camshafts which they have never seen before. Has anyone heard of this before? I am keeping my fingers crossed. Only around 2500 miles. Demarpaint, I did not have a chance to confirm if they are AC heads but they must be since they were made in February of 2013.
Thanks for the info. From reading here and talking to a tech buddy of mine I'm pretty certain the AC head is not the fix, it might be an improvement but not the fix. This really sucks!

He's seen a few 2013's come in with Feb 2012 build dates throwing the code and needing a replacement head.

Weren't the 2013's supposed to have the AC head? Or like I said earlier on in this thread it is possible that some of the earlier built 2013's have 2012 engines in them with AB heads. We are missing a lot of facts here. I would have guessed a Feb built 2013 would have the AC head? Maybe, maybe not? Maybe the AC head isn't the fix?

Early 2013's had AB heads...but the AC heads started around August of 2012 or so for the rest of the 2013's.

Then it would be safe to a$$ume that a Feb built 2013 has the AC head? Unless there were engines laying around with AB heads used in them?

It must be the AC head since they started producing them last year. They wouldn't start making the AB again, the Julian date is 0443A. They did not replace the head though. However, flat spots on the cams is a strange symptom. Has anyone gotten an extended warranty out of Jeep for their troubles?

No they wouldn't switch back to AB heads. What I was trying to say is if they had older engines in stock it is possible [slight chance] that they might have had the AB head, and some early 2013's might have gotten them.

Is this a typo? Did you mean Feb 2013 build dates?

I was more hung up on spelling, and trying to convey my point. Then I screwed up the most important part of what I was trying to say. Glad you caught it!

Yes I got offered lifetime powertrain warranty and turned it down. I wanted out of that POS and my money back. After a little push and shove and 6 months later. I received a check and the Heep was gone.

I go back and forth if I would take a lifetime warranty offer if something happens to my next Jeep. I just don't have enough faith in Chrysler to make right on their word and truly cover everything for life. I could already see the issues if I had minor mods to the Jeep being I had such head aches getting them to work on my complete bone stock Rubi.

Mine goes in first thing Monday to get my code P0302 checked. If its the head issue they are repairing it. They have pallets of new heads in stock...that shows how large the issue is.

My passenger side head was starting to tick again after replacement. The replacement drivers side "AC" was still silent after 8000 miles on it.

I won't have to worry about it any longer, the 3.6 is being replaced with a SRT8 6.1. Lol.

Dont think that would be a common issue. Mine certainly stayed right in the middle all the time before failure. Also the car was driven merely during short winter period (January-March), during which ambient daily temp rarely rised above 44F (7C)...

You might be correct, but the rate of failures seemed to be at it worst last summer and early fall when the weather nationwide was still warm/hot. As the weather cooled off heading into winter, the amount of failures also seemed to taper off. Maybe coincidence, maybe not.

Monday

While lightly wheeling a couple weeks ago my '12 JK's CEL came on and the ECO light quit working the engine ran rough. 1st the dealer said I had lef the fuel cap loose, I said NOPE! So the dealer did an "update"... (engine has had a tick for quite some time) Now CEL is on again... I called for service and told them I would need a loaner vehicle while they work on my Jeep and they said that is on my dime... 21k miles I am thinking I need a head job...

I call BS on you having to pay for the rental. If your Jeep requires warranty work longer than one day, call Jeep Customer Assistance and ask them to authorize payment for a rental. Some dealers will take care of this as a courtesy for the customer; sounds like this dealer doesn't know or care.

I was also told by the dealer and Chrysler that I had to pay for a rental for my appointment this Monday and no car would be supplied while they had mine. I had to fight Chrysler to get a rental and they agreed to give me one if they keep the car overnight. But it did take me to threaten to trade the jeep in for a different manufacturer haha.

The key here is anytime the Jeep has to stay overnight. The few times I knew my Jeep had to stay more than a day, I called JCA and asked for a rental. JCA contacted the dealer to verify the repairs and then contacted the local Enterprise. Other members have had similar results. While there is nothing in the warranty booklet saying Chrysler will pay for a rental, if the need is valid they usually come thru. Not sure why you had a bad experience.

You're onto something. I think the problem has to do with poor cooling of the heads, specifically the left head. Hot temps most likely exacerbate the situation.

Not necessarily. I recall reading that a Chrysler mechanic was heard saying that to break it & cause a misfire, start the motor after sitting all night (so that the valve is still cold and poorly lubricated) and floor it. I believe this defect in the driver's side head is exacerbated by cold temperatures (such as driving off while motor is still cold) rather than hot temps when all the metal has expanded and is well lubricated.
