The service rep said they flashed the computer with a program update and that the problem was solved.

I picked it up this morning and drove it for about 20 miles before the check engine light illuminated once again. Took it back to the dealer and received a call this afternoon saying that they were going to have to go into the engine to find the problem and should know something by tomorrow afternoon.

Has anyone else had a similar problem?
not to scare you but mine did the same thing on number 4 and 6. turned out to be two broken valve springs. no big deal they fixed it with the head still on and replaced all the springs. runs like a champ

Thanks. Wow 3 weeks. Dang I would have to have a loaner or they can pay for a rental car...will they probably not at the rate this has been going. I am very blessed to have an older brother and this is the email he sent to Customer service in my behalf. I am probably on Chrysler's Hate list now: Too bad he doesn't live closer.


Jeff, My Sister just fwd me a copy of your response to a warranty issue with her Jeep.Sounds you are an *** appointee to spread bullshit. I live several hours away otherwise I would drive her vehicle in for her and align the service people there inOdessa TX. Maybe the Media should be made aware of Them (Chrystler) being sexist and taking advantage of women. Like are they given bonuses for not providing warranty, almost sounds like the VA thing. A responsible person in your position would directly deal with the issue, Talk with the local idiot, have him call her, personally
apologize, arrange a service vehicle, and repair the vehicle.

westtexie Blastek,
Thanks for your help. You have calmed my worries.
I am going to take it to Auto Zone and have them do a code check and let me see the results and go from there. Not that I don't trust the dealership but I don't.
Thanks again.

No consequences. It's fine

westtexie I have had check engine light on for a few weeks on my 2012 Rubicon. I thought bad gas but after 2nd tank took it to Chrysler house in Odessa, TX for them to do the code check. I told man from service department on Jeep forum I saw where several owners were having check engine light and it was due to head problems. The service department man -Mario said " It's misfiring you need to get a tune up it's almost time anyways and if that doesn't fix it bring it back in and I'll flash ...the code and run a diagnostic on it.. If it's the heads I'll have to tear into it and it's a major time consuming job.
I said will you give me a loaner and he said probably not since their loaners are all out. After talking with my husband and checking our manual my jeep does not require tune-up till 94,000 miles I have 27,600. I am so upset. My husband called and left the service department a nice message and of course they have not called him back. I guess we will be going up there tomorrow and talk to them. This is my second jeep but beginning to wonder if it is worth it. I just found an article on-line where Jeep has extended the warranty on the heads to 10yrs. Guess it is major. So frustrating dealing with dealership here but dont have much choice unless want to travel a good distance.

Not to far 6 hr trip there and back with some driving for a few days in between. I have tried countless times with this dealer for a loaner when my wife takes it in and has the kids and never get anywhere with them.

blackrubicon My 2012 started coming on about 13k miles. I clear it sometimes it would stay off a week or so. Lately been coming on sooner. Never runs rough and no loss of power. Calling dealer today. Sure it's a head problem. Throws PO302 code.

Actually, it's covered under the 5 year/100,000 mile powertrain warranty. (Cylinder heads are an engine component).
08-13-2013 11:36 PM
Yellow_Fox Yeah I talked to the dealer today and thy said its covered under the 3 years 36,000 mile warranty. And I scheduled an appointment at a different deal that had it in stock. For Thursday, I haven't noticed any drop in mpg or rough idling the only rough idling I've noticed is when the car is warming up.

Definitely under warranty. When I had mine done, the "report" found one of the exhaust valves was sticking, and was burned and pitted. I would guess that continued driving would further damage the valve resulting in more misfires, rough idling, and lower milage, but otherwise safe to drive.

I had noticed some rough idling a few weeks prior to the CEL light coming on - so the valve was possibly sticking then, but not causing enough misfires to trigger the CEL.

As for the backorder - I had mine done last week, and it only took a few days for them to get the head (I'm in So. Westchester - not too far from No. Jersey). Perhaps try another dealer?

MikeK46 Amazing that the dealers also pretend that a software "reflash" will fix a mechanical misfire when you walk in, most likely knowing full well that you'll be back shortly.

God I hate those shady lying stealerships...they not only steal your money but your time and sanity.

Funny how I never had any issues with Infiniti, Acura, or Lexus dealerships, though. The service makes you want to go there...though you probably won't ever have to.
08-03-2013 07:25 PM
Xena1 The dealers have learned to lie from Obama! Chrysler sent me an email saying there is no known problem with the 2012 Wrangler cylinder heads! So like Obama we should agree.!NOT!
