Hard to have a solution with out knowing the source of the apparent sediment in the OP's overflow bottle.

Is there an actual problem other than the sediment in the bottle?

Maybe a good flush will solve it. But if it's causing clogs he might need to get a heater core, and or radiator.

I'd start with a paper trail.
Get the dealership and chrysler rep to put it it writing.
Then ask them to prove it.
Then go up the Chrysler ladder. Always getting it in writing.

Until he actually gets a lawyer, I would recommend OP not mention the word lawyer to the dealer or Chrysler. It can have a chilling effect on their responses if they feel defensive.

 

thanks, I do think it's ironic though, sand issues in a 4x4 jeep. I thought it came with a filter installed already, I will look into it further.

 

didn't catch that. I was confused for a minute lol

 

Ok, so I arrived at the dealer this morning with about 50 pages from the forum that addressed this problem, only to be greater by the service guy, telling me that they took care if it.
Confused, I asked what it was, and what did they do.
I have attached a picture of the sludge. They kept it in a big gulp cup to show me.
So they only cleaned out the overflow, and topped off the fluid.
Attached to my paper work was a star case report. I have attached this documents as well.
When I was ready to sign off on the paper work, I read through their report, and it did not mention the sludge at all, and only that it is caused by "off-roading".
I sent it back to have it added, and it came back just listing that there was sludge. I asked that they include the attached star case number as a reference, so that it is documented that it is not due to off-roading.
I then read the star case, where it clearly states the steps, and that includes flushing the system.
I asked why that wasn't done, and he said that is only to be done if the heater is not working.
I told them that is not how it reads, but the manger came out and said that what they did was the correct procedure.
I am to come back if I notice more, or if my heater stops working.
It is a shame that we have to fight with them to do the right thing.

 

Gotta love how 'well' they stand behind their products...

 

So they say it's mud from off roading?
If you got deep enough in mud to get it sucked into the bottle I think there would be evidence all over the engine compartment. And that you would remember it.

 

They wouldn't have covered it if it was mud.
They didn't comment on what it was caused by, but knowing that there are other known cases and documented fixes makes me feel better about backing up my case or anyone else that may have this issue.
By what others have listed, it is either something within the heater core from the manufacturer, or some chemical reaction from the coolant.

 

Here is the Chrysler 200 forum and they are having the same issues.
Pretty sure they are not off-roading in their 200's. Haha

Sorry to hear your going through the no heat issue. I am seeing more and more threads on heat issues with these JKs.

My dealership also tried to blame the sand casting on dirt from off roading, only problem is I never took it off road.

Took it to a different dealership (none Jeep/Chryser) and they were able to verify the heater core being clogged with casting sand.


Some, not all, dealerships will do everything they can to not cover the manufacture fault of sand casting.

Thanks. I read through your thread as well.
There has to be a tipping point to when they will take responsibility.
