|TiggerRC||I've got 61k on a 2012 with original heads. I recently noticed a misfire at idle but no CEL yet. Have any of you noticed the misfire before the CEL and how long was it misfiring before the CEL popped?|

PS: I can almost hear a green 2015 Jeep Wrangler calling my name.

This can be caused by the following: "Low Engine Coolant Level" (which I did have for while after the head replacement but now is OK) or "Leaking or Stuck Open Thermostat". In addition, the code can also indicate "Faulty Cooling Fan" (fan running to much) or faulty coolant temperature sensor (ECT) or faulty air intake sensor (IAT).
Is there anyone who did have this issue or code? If so, what was the fix? The Jeep runs fine otherwise.

|jofish||Had the drivers side head replaced about a month ago. Engine is much more quiet than it was and gas mileage is coming back. Only problem is a whistle type sound when really cold, 0 - 15 degrees, or there abouts. Noise lasts about 2, maybe 3 seconds and fades away. Now what? This is on first start up in morning.|

|gecko4||So, of course if you can wait, you should grab one of the first 15s off the line. Seems only fair...|

Mine was built the first day they built the 12s. I watched it on the tracker as they built it. It had 36k with no probs.
However, she died in a wreck Thursday. The guy put a hole in my engine block when he hit me.

Their press claims that less than 1% of Pentastars have had this problem. But interestingly enough it has shown up on Wranglers more often than the other vehicles... Since they claim it's a duty cycle issue in combination with "other" things, it makes you think.
On another note, I'm REALLY interested in the software flash that they are doing (mine was done last week) and the dealer made it sound real important. Have they lowered (de-sensitized) the point at which the P0302 goes off? They wouldn't do that now, would they???

29,145 and still nothing... (knocks on wood) But this should be in the bad right?
Looks like 2521B:

|aargh||It's the front cylinder #2 and yep, it's the head. They'll do a leak down test and you'll find it's low on compression, leaking through the exhaust valve. Had two done. Just hope they do the job correctly, anytime the surgeon opens you up theres a risk, same with a motor. I solved my issue by getting rid of it and got a 13. Good Luck|

|littleb222||forgot to add, my new baby is basically base, [the way i like em] 2 door rubicon only options are auto and color match top and fenders... so window was 34600|

If it were me,,,, I would as said above use it and try for killer deal,,,, if not going to give you killer deal then i would pay a lil more for newer... I actually just went through that on the 2013 i bought,, it was a holdover with 233 miles on it ended up with 4g off sticker, plus free undercoating, free trailer hitch, and made them do an oil change... I dont like the miles on it who knows how rough they were but had to take the chance for the deal i got..
If you do buy it, act worried and try to have dealer throw in extended warranty ease your mind a bit that way.. even if they wont you can get extra 2 year 24000 mile for about 500 bucks if you haggle..

|gecko4||Not that I know of. Only Chrysler can tell you that. It really shouldn't be a deal breaker. Use it for leverage to get an extra grand off.|

Is there any way to find out just from the VIN?
|02-09-2014 03:28 PM|
Or do you have to look on the cylinder head for the date to be sure?
|02-09-2014 02:44 PM|
That 2062 is the Julian date of the heads shipped as replacements through service parts. This date stamp is etched into the side of the head itself. It is visible from the top, but you have to stick your head up by the master cylinder and look down towards the centre of the head to see it.
My Julian date on the left head is 2022, and my jeeps production date was July 27 2012. That puts the head built just a few days before the jeep. I'm sure all 2013s had the new head, regardless of the date code. For the 2012 models to have the new head, I'd guess it would be around 1802 and up.
|02-09-2014 02:28 PM|
Build date will be on inside of door jam, next too or below tire pressure stuff... from what i have gathered 2062 is the safe number, meaning the 206th day of 2012.. which off top of my head i think is in july.. I just bought a 2013 jk rubi yesterday, build date is sept 2012 so I have my fingers crossed that i am good to go...

Hi everyone, I'm glad that I saw this thread.
Without reading through almost 200 pages, can anyone summarize what dates or engine numbers I should be looking for? Where can I find the date and engine numbers?
I'm asking because I was about to buy a 2012 with 15k on it. It's on a dealer's used lot, but it's not a Jeep dealer.
Should I buy a 2012 at all?

|jofish||Once mine threw the code, no ECO sign on dash and my remote start would not work. Service writer said the code was the reason for that. Been extremely cold here, 5 above at night and it is quiet after start up since I got the new head. Put on around 300 miles and all is golden. Hope it stays that way. Oh, I lost about 2 MPG after it threw the code. Hope that gets better.|

|gecko4||More often than not, the dealers are good about it. You just hear about the bad experiences on forums more so than the good ones. I'm sure they'll treat you well.|
