There are lots of issues that can get worse and/or appear over time.

GM's issues with their pink coolant and it eating away at headgaskets for instance. For the first while nothing would happen...but eventually overheating and head issues.

Ford's issues with the 8.8" rear axle in the first gen IRS Explorers ten years ago for instance. Drove fine for a while and then started having all kinds of gear wear issues.

Jeep's issues with TJ wiring harnesses. If my buddy's '02 TJ had the issues it had at 65,000 with lights, turn signals, dash indicators, radio, and other electrical dohickies when new Jeep would have never sold it. It's so bad there are Painless Performance wiring harnesses for TJ's. I believe that's the newest vehicle Painless makes an entire wiring harness for by a lot.

Just because something is an issue doesn't mean it will immediately happen. The makers for sure don't want to be fixing a bunch of '12 vehicles in '14-15 if they can fix it now. However they have a LONG history of minimizing issues until they are FORCED to do so by the government or public attention. Seems like this habit has gotten worse since the rise of the internet and social media. These forums are excellent sources of information (along with inuendo) but dealers and their employees still often fail to admit that the general public can now walk into a dealership ready to buy/own/operate a car FAR more informed about a vehicle than the sales staff or even the mechanics/service writers/managers/staff/etc.

This is true. I've owned 4 keeps before this one. When I went in to buy my 2012, I knew more about the vehicle than the salesman. My wife laughed when he started asking us questions.

Its ok "thedrod" - lol, truth is what it is not trolling just pointing out an age old addage that works. If you agree fine, if not oh well... My guess is you are kicking yourself for having shiney ball syndrome (had to have that 12 as soon as it hit). I think mid year builds of the 13 will have worked out this major flaw and this engine will be a good one for the long haul.

The head failure has nothing to do with the 3.6 being mated with the Wrangler (as someone stated previously), it was a batch of improperly manufactured parts.

This thread is going to shit. Its a bad head on an engine that has a 100k mile warranty! I dont get all the fuss. If it ticks or breaks, it will be fixed.

And all you people bashing the 12s can keep on driving the old reliable. Check the forum, plenty of pissing and moaning about the 3.8 too. You are just stuck with a weak motor with just as many issues as the stronger 3.6.

Any issues with either motor will be fixed over the life of the warranties. Happens to every make and model out there as the issues come up and are solved.

Found this link on Allpar : http://www.autonews.com/apps/pbcs.dl...-pentastars%22

Reading through the article, it is obvious to me that Chrysler is not going to accept any responsibility for the head issue unless forced. They say it is not a "design defect", but the apparent remedy is a re-designed head !
They also try to pass it off on some vague, unknown fuel characteristics and certain driving parameters. In other words..........NOT OUR FAULT.
I have heard others say that this issue would present itself before the expiration of the engine warranty. IF, as Chrysler is claiming, that it involves only certain (unknown) parameters then those things may not happen until you have had your JK for 5 1/2 years or over 100K. In my estimation, this is merely a typical cover-up by a big manufacturer. Unless it is a "safety" issue and they are forced into a recall, they are never going to accept responsibility. I have been through this with GM and the 5.3 piston slap issue as well as Harley Davidson on a valve train problem.
Unless there is a class action to force Chrysler to divulge the details, we will never know what the problem is or if/when we are going to have the problems that so many on this forum have already had.

Don't get me wrong, I LOVE my '12 JK, but just the knowledge that they are seeing "over 500 /week" with this problem is pretty disconcerting, just waiting and wondering IF or WHEN.

The fact that there is nothing specific given about the head changes, and no one can see to come up with any information on what is exactly different with them. Same head, different number.

I do agree that if there's a problem it will surface in the 5 year 100K warranty. But what if they try to shut me down cause I change my own oil or I have a winch infront of the radiator "blocking" air flow? Also with all the rumors that they have thousands on back order it's tough to have warm fuzzy. Even if they say they have plenty. I'll be interested to see what heads are on the first 2013's. I was one of the avoid the first year guys.
