We have 7,980 miles and after the 2nd oil change, the technician didn't or couldn't (and didn't tell us) reset the message center that was telling us to change the oil.
We brought it back to the dealer and they couldn't reset it and told us they needed to call the factory and would get back to us.

After a day or so the check engine light came on, took it to dealer, they still didn't have answer on why they couldn't reset the oil change indicator and would add the check engine light to the problem list to discuss with the factory.

The next day the warning came on for DPF 80% plugged. So I told the wife to drive on highway for 30 miles before she came home, which she did with No improvement. (NOTE: IF YOU HAVE A CHECK ENGINE LIGHT ON AND YOU GET THE DPF WARNING, IT LOOKS LIKE IT WON'T REGEN, SO YOU ARE JUST USING UP YOUR MILEAGE UNTIL LIMP MODE KICKS IN)

The next day on the way to a appointment, wouldn't you know it went to 100% plugged!! She says it wouldn't go over 30 mph? (she was upset). I went out and swapped vehicles {good thing we have a spare} so she could make her appointment in time and took the vehicle to the dealer. When I got in the GC it now would only do 16 mph (at 3000 engine RPMs)!!! So there I was driving my expensive Chrysler product in the breakdown lane with the flashers on all the way to the dealer. On the way I couldn't help but to think how I would love to leave it there for good.

We'll see what happens but it does seem to be turning out like the Mercedes diesel powered GCs from the 2007 vintage with all the emissions problems.

Dealer fix it "No problem" they say. DEF nozzle plugged with crystalized material. 80+ miles on speedo, somebody had a nice drive probably to regen the DPF. I asked if disconnecting the battery would reset the codes and the service manager said that he thought it would. So keep it in mind to get back home if needed when it cuts you back to 16 mph, just disconnect the battery to reset computer. He also mentioned that they took samples of the fuel and DEF fluid for testing.

I'm curious how long your dealer had their supply of DEF and how they've had it stored? If it crystalized and plugged the nozzle there's really something wrong there. That's a hell of a long test drive as well.

We haven't bought DEF from the dealer, we get it at NAPA when they had it on sale.

supposedly DEF is date stamped.. Although the two boxes of Peak Blue that I have purchased through Amazon have escaped my ability to decode. I would think if it crystallized and clogged the injector that the connection was not secure and evaporation resulted. And so far I have not laid eyes on the battery......I am washing mine today and will take a few moments and look for it. I tried to reset my oil life meter( my shows 49% life at 1600 miles ) but had no luck with the procedure from the manual. Perhaps the indicator must be on in order to reset the meter...... If the vehicle will not regen when there is a MIL or change oil indicator on (and that's only two conditions identified so far) it's like being tethered to the dealer. I know a standard code reader will clear the MIL but don't think it will have any effect in regen or oil. Mine cost 120.00 and is worth every penny. Even if you never reset a code but just use it to stay informed.

I've never had a problem resetting my oil life meter by following the manual. But then I've never had a MIL light lit when I did it.

The battery is located underneath and just behind the front passenger seat. If I remember, you need to slide the seat all the way forward to access the battery through a cover in the floor. It's a gel battery... sealed, no liquid. I can only imagine how expensive that will be to replace when it dies.

Don't know what the battery setup is with the diesel.

"On Sale"... as in, "We need to move this now before it hits its expiration date!" kinda sale?

Jeep is now clean..... At least on the outside. Found battery under passenger seat. I moved seat all the way foward and up. Looks to be a very tight fit. But the rear terminal could be disconnected without any problems.

I don't know, is that like buying diesel fuel at a station that is .20 or .40 cents or more overpriced then one across the street thinking it is better fuel, or is the cheaper fuel "fresher"?
To me, a properly designed vehicle wouldn't go into a tailspin because you bought some fluid at NAPA (I could see the Dollar Store maybe). Is it too much rocket science to put a adequate screen or filter in line?

Can't argue with you there. A number of people have gotten stuck in limp mode due to issues with DEF and/or its injection system.

Without looking I'd have to assume this 3.0L diesel in Europe uses DEF as well. You'd think that in the years it's been in use over there they'd have the whole DEF system fine tuned before it hit the US market. If that's true then it really can't be blamed on first year production bugs.

It'll be interesting to see what your dealer finds out with those test samples.

Mine had the Crystalized deposits... it was one of the original builds and I believe this was related to excessive idling while being shuffled around JNAP. It gave a Regen warning in the first few days which also pointed to this. DEF Injector was replaced but I still get an occasional MIL but my understanding is Engineering is working on another PCM update beyond the one they just did in April.

Edit, sorry I forgot, I did also have an issue with my first oil life reset and needed to do it via WiTech.

 

[M5040]

I wonder if they will even let me know what they find? Too technical for the customers, unless it's their fault.

 

[MDBones]

Keep bugging them, maybe they will. Most likely they'll just try to baffle you with BS if they do.

I just had my 1st oil change done at 6000 miles this Saturday. Now I have the MIL 2 days and 55 miles of driving later. This is not cool. Hopefully it is something simple and not a gummed up DEF issue like you. The dealer also forgot to reset the oil life indicator. I think it took me about 10 to 15 attempts at the clearing procedure to get it to reset.

I had the software update done as it seemed like the oil life went faster than expected. Yet it is already down to 98%. I don't understand the rapid drop when I barely drove it and the driving that was one was mostly freeway.
