2012 Sahara here from 10-22-11. 6200 miles, run synthetic oil since new. No tick or click. This engine is so quiet it is hardly audible when idling with the air on. great machine with power to out run a Ford Chipped Powerjoke this evening from a stop light. Still laughing at the old guys look out of his side window. hahaha

Its says in the article that the penastar engine will not return in 2013. What will we get instead? And will this make the 2012 model a "lucky to have" model since the pentastar is not returning?

I think you read the article wrong, it's the 3.7L V-6 in the RAM 1500 that's not returning.

The article says the 3.7 used in the Ram 1500 won't return, not the Pentastar. Chrysler is married to the Pentastar as the only 6 cylinder power plant in any of its lines.

Right. Sorry for the confusion.

I've been lurking here since January just to get as much info as I could before I "took the plunge" and bought my 2012 JK. I just noticed about 3 weeks ago that the engine started sounding like a sewing machine. Well, today it sounds almost like a Cummins. I have a visit to the dealership scheduled on Friday. I waited due to the fact that I thought I was just being paranoid after reading about the "tick". Unfortunately the sound has amplified well beyond normal valvetrain noise. Say a prayer for my baby.... Thanks for the valuable info you've all been unknowingly supplying me for the last 7 months! I really appreciate it!

I'm in the same boat, let us know what the dealership tells you. I'm taking mine in Thursday.

Just heard from the dealer. Cylinder head misfire. Here we go. Looks like heads are still on back order. No ETA. Asked if I could drive it in the mean and the tech said it's riding pretty rough so he wouldn't suggest it. I did notice yesterday that I had some issues after shifting to second until I reached about 2000 RPM. So now I'm stuck in a PT cruiser until I get a new head.

Now the wait begins. Calling Chrysler today to see if they can move things along. Also, talking to the parts guy who I've built a good relationship with to see if he has anyway of making sure I get a head manufactured after the retooling.

That sucks. Smart move asking to get a head after the retooling, no point in possibly having a bad head installed a second time. I'd be interested in any info he shares with you, I'm sure others will be too. Good luck!

I got a call from my dealer yesterday, the head (that was supposed to be here last week) is scheduled for delivery on the 24th.

A little recap on my story: about 11k, my MIL light has been on for a few weeks (at just over 10k) throwing a p0304 (misfire cylinder 4) code yet I never had any tick until today. It only last for a few seconds when it starts and then it goes away. Sometimes it idles rough & I can feel the misfire every once in a while while driving - the rpms drop for a quick second and then its back to normal.

The good thing is that they are taking care of it and it appears (from various posters that have had the replacement)to solve the problem.

Keep us posted.

Since reading various threads of "the ticking pentastar" I've been paranoid lately. Today when i started the car before heading to work, I noticed that it was ticking pretty loud for a few seconds. I'm not sure if this is normal or not, but today was the first time i started the car without the music blasting so i really haven't paid attention.

FYI, my jk was built on april 2012, and purchased July 1st and i have about 750 miles.

Don't get too paranoid. Read back through this thread for links to youtube showing the before and after "tick". If it is a head issue it is so loud it sounds like a Diesel engine on the driver's side only.

Also the dealer may not do anything until a check engine light comes on for it.

Many that have had the issue said the dealer told them to keep driving it until the parts come in. I don't recall anyone reporting being stranded by it, it is just annoying.

Drive on, if you have the issue it will become very apparent especially when the CEL comes on. If it does happen call your dealer and Chrysler customer service to begin case so it is fixed in a quick fashion. Otherwise enjoy your Wrangler and put it out of your mind.

Good luck on getting the redesigned head!

I'm confused. I wish Chrysler would come out with some detailed information as to what the problem really is/was.

Tomster
If they are redesigning the head it's pretty obvious the original head has a design flaw. Did they re-design the right head too even tho the probs seem to be left side only? It would be nice if an actual tech who knows whats going on would esplain the problem with the head design, por favor. Chrysler ain't gonna do it until forced.

I bought my JKUR 6/2/2012, just had my oil changed. No tick before the oil change and strange thing - I went to the dealer with 700 miles on the jeep and they wouldn't do an oil change. They said the light would come on when it needed it. I took it in Monday for an oil change with 2917 miles on it and had to playfully haggle with them to do the oil change.

Well I stopped at Walmart after getting oil change done to pick up supplies for the trip and decided to use remote start as I was walking through the parking lot. As I got closer I heard a loud lifter tick and thought WTF, I was pissed.

I drove home to confirm and pulled into the garage and it sounded fine, quiet as a mouse. Today started it up and after it warmed up ticking on drivers side again. Not loud like day before but ticking - ran some errands got home and it was quiet.

We are leaving on Friday to drive as much of the NC coast as possible starting at the Virginia border (Corova beach area) and driving all the way South till Wilmington. I hope the jeep makes it because once we get out there on the Outer Banks there is no quick way to get to a shop.

Have any of you guys ever had the tick intermittent at first? If not how many miles have you driven with the tick on/off before it became a performance issue?

I am not canceling my 4wheeling vacation, haven't been on vacation in two years. I haven't told my wife about any of this, don't won't her worried.

Mine ticks on start-up, after about 6 to 8 seconds it's all quiet and so far no performance issues... 8,8XX miles.

I have 3000 miles on mine and it's probably the quietest engine I own. Jan build, although build date doesn't seem to matter anymore.

Lift tick when first start and disappears after warm up 1400. Miles. Been listening to jeep and all engines as I'm walking about. Must say all engines have a slight tick sound. It's easy to get overwhelmed here. Keep in mind those who posted the real problem said it was extremely loud like a diesel engine. I never had that yet!

That's normal. Keep in mind the filter is at the top of the engine, it takes oil a few seconds to get there, and the filter probably drains down when sitting for extended periods of time. The problem is when the tick doesn't go away, its on the left side of the engine, and isn't coming from the fuel injectors. It will also trip the CEL.

Mine was never loud like a diesel engine. And at times I questioned if it was a tick or not. But I also started to see performance and mpg issues. Then the CEL came on about a month later.

So it is possible to have the problem without a super loud tick.

I do agree that it's easy to convince yourself that you may have a problem when you don't. The reality is if an engine has a problem the CEL will come on at some point and there is a solution.

2012 JKU with 11,778 miles. CEL light came on briefly then went off will driving. I have been hearing the ticking sound getting louder and louder on the drivers side. Yesterday I brought it to my local dealer and stated what I have described and the service manager said his personal vehicle 2012 Jeep Cherokee had the tick after 2,500 mile and the number two head was replaced.
He said he has to follow Chrysler's policy to flash, then valves, then replace head but had 2 heads in stock so he is trying to get permission to replace head.
He said I need to contact Chrysler to get approval for loaner. Anybody have the number to Chrysler?

Thanks!! What do I need when I call to tell them about the problem as it's only been a day and a half since I dropped off the Jeep.
When can I ask for a loaner?

Basic info (owner, address, etc), your VIN and a description of the problem. I would ask for a loaner right away.

Also, you mentioned your dealer has heads in stock. I would inquire as to when they were acquired. They could be the old heads still and could cause the same problem. It may be worth asking them to order a new one and waiting, to make sure you get the newly machined head.

I have only heard one real tick in person and it was fairly nasty....a big difference from injector noise or start up tick...which is common in many vehicles. I am glad to hear they are fixing these and I'm confident the 13's should be a safe bet....and maybe some of the late '12s as well....time will tell.
