I ment to say the heat works great now from all four vents. Yeah the air is realllllly hot now from vents, floor. it seems on some of these other post that the 2012 wranglers are having issues.

The 2012s are indeed having issues, as expected. But, this particular issue isn't only on the '12s. The 3.8L JKs from previous years also had the same heater core failures from the casting sand/sludge. Unfortunately it's a major job to repair because of where the core is located behind the dash on these things.

If I take in my jeep, and they fix it, how long can I expect to be without it? I kinda need it, and can't afford a rental at the moment... Or do they provide me with a car till its fixed?

I think you should be asking your dealer those questions. They might have to order the part for whatever repair they do.

Your right. Well I stopped by today after work. I checked a few days ago and my coolant looks kinda like tapioca pudding. I was in the field and got it to the dealership as soon as I could. They told me to come back on Monday. Then I overheated on my way home and had the Jeep towed backup them. We'll see what happens next... I can't afford a rental car so I hope my insurance covers rentals. Ill keep anything I find out posted on here.

The word on the street is that Chrysler is now installing filters in line with the cooling system to catch the sand/crud that is floating around in there in hopes of preventing future problems. However, my dealership didn't say anything about this when mine was in the shop for 4 days a couple weeks ago.

They said the wrong coolant was used, I called valvoline and they said they didn't touch it. I'm going down to watch the video of my oil change right now. Chrysler says they won't cover this under warranty. Even if valvoline never screwed with the coolant. All gaskets are fine and compression check came out good on all cylinders... Boy am I ****ed. What the hell happened? It's got 6000 miles on it I've never touched the motor. Chrysler isn't willing to pay for it. Neither will valvoline.

Seriously? That is some B.S. right there.

I'm seeing a ton of these heater core issues popping up on the various forums now that we are approaching winter. Since these '12s are under warranty, and the parts/labor bill is huge for this repair, this might end up being a fairly serious issue for Chrysler. I expect that a bulletin will be released before the end of winter.

Holy Oversight, Batman!


I gotta say, this does not make me want to buy another Jeep product. Getting the sand out of the completed casting has to be about #4 on the list they give out in Manufacturing 101.

I just got mine back, I told them about this problem about it being the most likely cause but they insisted that it was someone else's fault and that the wrong coolant was used in it. So I pay to have it corrected, I get it back and the problem is worse. Heater blows cold and foggy now at the same time. Wtf Chrysler. I scheduled another appointment on Friday. If this ends up being a tsb or factory recall I want my ******* money back this ****s getting rediculous.

Funny story, I buy a jeep with no AC in the summer time and lemon'd it out, just to trade up to a jeep with no ****ing heat in the wintertime...
How hard is it to get the jk right after 6 years. Chrysler remains on my **** list.

Took mine to the dealer today for same problem. They said there is debris in the cooling lines/heater core. They are replacing the heater core. They also said there was debris in the radiator that looked like internal decomposition so they're replacing the radiator as well. Glad its all covered but scary there are so many problems with this. Hope this fixes mine.
