Yep, it's gonna kill the resale value just like bad optispark ignitions killed the resale of 1992 Corvettes and 1993-1994 F-Bodies.

Oh, wait, that issue didn't kill the resale of anything, and neither did the oil starvation of 1997-1998 LS1 cars.

Thats one of the reasons I bought mine, I talked to the kid salesman, never heard of such a thing, said he talked to the serv dept and they havent seen it either,
But when I talked to the serv manager, he was open enough with me that he told me they have replaced a few, so at least I got someting out of him.

So there not all mums, but I agree, most of them are.

I just took it to a place in Weymouth that I was referred to and they were great!
Hope you have better luch down there, I am a masshole, I grew up in Brockton, then in east Bridgewater. So I know the area pretty well, We have some great trails up here in Nh, if your ever up for a ride, let me know..

And I smirk because I'm probably the only one not running around like a chicken with its head cut off over the whole issue. My engine ticks for about three seconds upon startup and stops. I also hewr some ticks when I'm in the garage, but guess what...I DON'T CARE! If it throws a CEL or starts knocking, I'll take it in, but until then, it's business as usual and I'm going to enjoy every mile I put on my Jeep.

FYI Sueby did not have a tic but through a CEL
Guy at work not on these forums ticks. It was pretty loud. Kinda sounded like my old Tj

Complete Jeep noob here looking to buy a new JKU, if it's going to happen will I hear this noise right away on a test drive or does it appear after so many miles?

You have to wait, if they ticked from the get go they wouldn't leave the lot
most hear it between seven and twelve thousand miles

Many left the lot ticking, people were told it was normal for the Pentastar engine. It was only addressed if accompanied with a CEL. My neighbor two doors down told me earlier this evening his 2012 JKU just threw a CEL. He said his had a slight tick when he bought it and was told it was normal. He's had it for 3 months and has 2,500 miles on it. I showed him how to pull codes and he's got the P0304 code. Must be my lucky day, that's the second Wrangler I encountered today with the problem.

I feel bad for my neighbor he's got one fine looking Jeep!

Then I stand corrected. But do not assume purchase sound absence means problem free

So does this mean I'm not actually going to see a CEL flashing and I need to check for it myself, or what?

I have no idea if you're going to see a CEL or not. As I understand it a tick w/o a CEL will be considered normal noise. Without a CEL on bank 2 Chrysler isn't going to do anything and odds are you don't have a problem at the moment.

I think it was you who said something along the lines of drive it and enjoy it, and deal with it if it happens. Sound advise for anyone who owns one at the moment. Not everyone is bad, so they say, you might have one of the good ones I hope so!

You can check for codes, with a scanner or by turning the ignition key from off to on 3 times w/o starting the engine. If there's a code you'll see it, if not you'll see the word "done", meaning there are no codes and you did the key off on procedure correctly.

I also think once Chrysler sorts through this the Pentastar engine will go down in history as having some early growing pains, but turned out to be a good engine. JMO

This thread just seemed to be cropping up and gaining ground right before I placed an order for mine. I followed it for about two weeks and was seeing people talking about build dates up to March having issues. By this time, it was mid/late April and I just decided, "Ya know what, I've wanted a damned Jeep now since 2010 and now's my opportunity to get one. If I buy something else, no matter what it is, every time I see a Jeep I'm going to wish I'd gotten one."

I'd lost my 2005 STi in a bad wreck in the beginning of April, and while I loved that car, I hated the very things I loved about it, if that makes sense; the performance/stiff ride, the heavy clutch, the compact size, etc. It just didn't make for a great daily driver. I'd considered a new one, as I've heard they've softened up a bit, but it was just time for something new. I had plans for things I wanted to do, and an STI just wasn't gonna fit the bill. While it would have certainly filled that "hole" left by my 2005, it wasn't what I really wanted. I could've gotten an STI and probably been satisfied, but every time I saw a Jeep I knew I would look at one and say to myself, "Damn, I wish I got the Jeep."

So, on the note above, engine ticks be damned, I was getting a Jeep, and I did. I figured instead of risking one built in a "bad" period, I'd order one; the build date would be in May, and considering problems were only being reported in early models up to around March, I figured I was out of the woods; a later build date meant less of a chance of getting a dud.

As with any new engine, there are teething issues. Look at all the evolutions Ford's 4.6L went through. It started out making 215 hp in its first year and by the time its run was up, it was making 315 hp and was a pretty decent powerplant.

IMO, if anything, Chrysler should have tested the Pentastar longer than what they did; stick a few on the road for a few years and keep it "hush-hush," but from a BUSINESS standpoint, I can see why it was released when it was. They were simply outgunned. GM and Ford had newer motors and Chrysler was soldiering on with the same old dinosaurs. The engines in Chrysler's lineup simply just weren't competitive any longer. While that doesn't make any of us feel any better, that's just the way it is.

In the end, I also think the Pentastar is gonna be a decent engine, and until I have issues with mine, I'll stand by it as being a decent engine. I'm far more concerned with Chrysler's track record with their transmissions than their engines.

So, babbling aside, for those dancing around about whether to buy a new Wrangler, shit or get off the pot. Quit dancing around, doing the "poopy dance," and whining about whether to get one. Just go out and buy the damned thing and enjoy it until it springs an issue...if it ever does.

Mine has been starting REALLY hard the past week or so. It makes a loud shutter/clank when starting and then immediately goes away. It's always had a slight tick but I can only hear it when next to buildings, etc. It threw a CEL and was running really rough back in January but it never registered a code and it hasn't done that since. I am still under no illusions that it won't happen to me and everyone else and anyone who thinks differently really needs to take a basic logic class.

13024 miles. I also want to add that since 12 miles the left bank was louder than the right bank, I changed to synthetic oil at 3000 miles and it quieted down quite a bit. But it is a bit louder now.....

Con we agree on a lot of points. I think the engine was over hyped, eg: Wards, and under tested, big time. I also think Chrysler will get it right, after all they bet the farm on it. I also believe there is a gag order on our resident insiders talking about it, that has become obvious to a few of us. It is what it is.

I respectfully disagree with your shit or get off the pot comments though. Some of us, myself included want no part of buying into a problem, warranty or not. I almost went the lemon law route years ago with Ford, it was a hard battle, I won, but it took a lot of time and energy, I'd rather not do it again. In my case I didn't know I was buying into a problem, in this case I do.

I'd never tell anyone they were crazy for buying into a problem, I respect their POV, I hope they respect mine. I haven't given up on Chrysler yet, I have the resources to buy, and will once I'm satisfied they fixed the problem. I have no problem waiting, if it means another year so be it.

I enjoy this site, I learned a lot, and want to participate in this thread.

Hopefully you have no problems with your Wrangler, and if you do, you obviously have the personality and attitude to handle it.

As far as their transmissions, I think the WA580 is a solid unit, much better than what they used in the past. I can't comment on their manual tranny's though.

I too disagree with the "shit or get off the pot" comment above. I've always been a GM guy and have never bought a new vehicle that had a known common problem. My Camaro was an early build (03/10) and even though it was a new design it has been completely problem free for almost 2 years now. Luckily for me I'm in no rush to purchase a JKU so for now I'll look for a low mileage 2011 or wait for a 2013 and hope they work out the bugs on the 3.6.

A lot of vehicles have teething issues that require warranty work. I'm not going to keep it till 300k. If it needs a new head before 100k and a trip to dealer so be it. The reasons I wanted a wrangler aren't satisfied by to many other vehicles except a used wrangler. hopefully they figure it out.

I don't consider major engine work a "teething issue" a bad fuel cap, maybe. But not a damn cylinder head.

Same here. I read about these issues and it still didn't keep me from ordering one. I always buy the extended service plan to cover my expected ownership period anyway. I will just say to the dealer, "if it ticks, you must fix."

The 2012 JK engines have never been made in Mexico.

Also if this is the case that literally every JK is having these issues, that would point to a design flaw, right? Not a manufacturing error.

I know there are tons of posts to read, but you wouldn't have to read too many to know that this is indeed a design problem and there has been a new head design. Production on the new heads began in late June or early July.

That's the info I have, AU95. I wish I could point you to some source but I can't remember where I read that. I can tell you that it was more than one place, though.
