|Tseg||My 2012 Rubicon built Dec '11 with 23K just went in for a new cylinder head. Happened the day before I was traveling out of the country... So it is at dealership while I'm in China... Hopefully all is fixed by the time I return at the end of this week.|

Took my Jeep into the dealership last month. CEL P0304 misfire cylinder 4. 23,000 miles. Jeep build 02/27/12. Tech performed leak down testing procedure and verified 155 PSI and 55% leak down on cylinder #4. They replaced left bank cylinder head and gasket set.
They had my Jeep for 2 LONG days and gave me a rental car. I wasn't having any problems with how it ran. After a month, it runs the same. No problem.

|rdg04578||Looking at these results--31 percent have had an issue--glad I got a 13 and I would be wondering if I didn't have an issue yet--that number is huge|

|Bigalsjkru||21k on my 2013 JKRU with no issues but my wife's 2012 grand cherokee is in the shop getting heads and intake manifold replaced as we speak. Started running like crap then check engine light next thing I know she's out of a car with only 32k miles.|

Head problem poll
2012 Rubicon has had slight ticking at start up only since new. 26k and CEL came on and dealer confirmed head replacement required. She never ticked bad and always ran great, hoping this will be the only head issue.

|BrokeRugger||Cel came on right around 32k. Head is being replaced now. 2012 2dr Sahara received 11/2011.|

My 2012 Rubicon has 10k on it now and the engine ticking started around 6k. I figured I would wait till all the Chryler/Dealer/Customer argueing was done so that I only had to go in once to get the issue resolved. Dealer replaced
Now my Jeep is back at the dealer after driving it for 200+ miles and the tick is louder than before. Dealer has had it 2 days and claims they do lifters/rockers and garunteed me the noise would not come back. On a side note when I picked it up the dealer told me they went ahead and took care of the recall for the power steering line replacement. When they took the line off fluid poured all over the frame, taking my rustproofing and frame paint off. They thought it would be good as new with a spray can of undercoat....wrong!!!not hear anything abnormal about the engine and the ticking that I am hearing is from the injectors.
Also, is anyone having trouble getting a loaner car from their dealership? I was first given a Dodge Caliber that reaked of smoke so bad I got a headache. Now the second time back in the shop I am given a PT Cruiser with 70,000 miles and the spoiler ripped off the top.....
I am a big Jeep fan and Chrysler supporter but this may be my last Chrysler product and for sure last trip the that particular dealership.

|wesleyfrncs||I know i dont have a 3.6 but my 2010 with 18k miles just had to have its head changed|

|ikeymay||20k miles on mine and it just went into the shop this morning for a check engine light. code was misfire on cylinder 4. updated computer and reset. engine light came on again ten miles later. now it's gonna be at the dealership for who know how long, because the head is on national back order due to high demand. my dealership has done "six or seven" left head replacements on pentastar engines, so far. it is, they told me, a "know issue with these motors". this sucks. I mean, you buy a new rig to avoid this kind of problem, right? she-it!|

8,500 mi on a 13 built last Oct. Knock on wood problem free.
About 2,400 have been highway road trips and 1/3 or so for 4x4.
Climbing the steep grades around Needles Ca on I-40 the eng temp climbed to around 3/4 on the gauge a few times but would cool back down on the down grade. Very happy so far.
I bought her last Dec.

|Steady||I have a 2012 JKU rubicon with 33k on it, and havent had the engine light turn on or any idleing/power problems... i have noticed a slight ticking sound but like someone else said i just figured it was the way the 3.6 sounded and never gave it anymore thought till reading this thread lol thanks guys... Could there be a head problem without throwing the check engine light?? i guess im going to have to pay more attention to it now and go from there...|

|wat3rdog||I have a 2013 JKUR built in October of 12. I just noticed a noticed a noise coming from the passenger side of the engine. It sounds like I'm hearing the lifters and I can here it from behind the front passenger wheel with the hood closed and better with the engine beauty cover off. I just got back from a 500 mi road trip with no issues until after grabbing a bite noticed it had a bit of a diesel 4cyl sound. Any thoughts on my issue would be greatly appreciated. She has 2,223mi. on her.|
