It is obvious that Jeep/Chrysler knows which vehicles got the bad heads based on VIN numbers which identifies build dates...
When I brought mine in and mentioned the ticking/bad head issues reported by other owners they told me mine was on "restricted" status and they had to follow STAR procedures and Chrysler has to approve the head replacement, only after the ECM flash, lifter replacement, etc...
So Monday they will start the "real fix" to replace my left cylinder head, hopefully this will be the end of the problem once and for all

My dealership probably doesn't do a whole lot of volume in wranglers. I dropped by there today to see if my VIN was listed as restricted. They couldn't find any indication of it and also stated that they never heard of the head issue. I guess I'll see what they say on Monday when I drop it off to them. My build date is 8/11 and the ticking can be heard at more than 3 feet away.

all quiet on the eastern front
Purchased my '12 Rubicon last August and have no issues so far...9500miles, some of which were 9hr/80mph straight drives. I do get a "morning dove" cooing sound from my brakes upon stopping and starting out...subtle, but wasn't there when new?? Weird, maybe the pads holding up a little after they get warm.

And I haven't demanded anything, I only made a simple requested. (wow) Sorry if it offended you.

I will gladly send you a copy of my work order as I have for a couple of other forum members if it helps you get yours fixed like it did for another forum member.
Just let me know and send me a PM if interested.
Once again, hang in there!
~PEACE~

Thank you for posting your invoice. This gives me warrant to deal with the ticking problem that I suspect I already have.
I apologize to everyone for being so adamant in my request, but I didn’t want to go into the dealer unprepared.
I traded in a perfectly good 350Z for my JK sport S. I can’t express how disappointed I am discovering this problem with the Pentastar 3.6
I just hate the though of someone tearing apart a brand new engine.
I’m also pissed that I didn’t wait for the 2013, and keep my Z for another summer.
Now I’m caught up with the decision whether to trade in my 2012 for a 2013.
Anyhow it’s time to deal with Chrysler again or maybe sway over to Ford.
I still love my JK.
Cheers
