I reported same to dealer.
2 weeks ago, we were heading to the coast, for a seachange, with our 20 foot, (about 2.5 ton ) van on, and I noticed the temperatures of both motor oil and motor water coming up. Ambient 26 degrees. I pulled up at Moonbi, (just before the Moonbi Range) to check the van brakes we not dragging or any other sign of a problem. Everything seemed just fine.
As I had run this range before with this car and van, I decided to push on, keep the revs up a bit and taking it easy.
About 30 meters from the top, we entered limp mode, I snuck to the top and pulled over.We came out of limp mode as I pulled over. Radiator had boiled but was now coming down in temp. However , oil temp was still going up !!! As it was a nice downhill run for a few km, I decided to push on. Water temp came right down, but oil temp continued to rise !!
We pulled into Bendemeer, oil temp was now show 148 degrees, stopped motor to let is cool right down (2 hours), then slowly topped up the watrer, motor on idle. The top plastic water tank was like a small volcano, and did not settle down, seemed like a blown head gasket. NO noises from motor.
Vehicle tilt trayed to Tamworth dealer, caravan recovered next day.
Dealer removed heads, no problem here !!! Suggestion made it might be the EGR (exhaust gas recirculator). Specialist testing revealed it was indeed the problem, pressure testing revealed a good leak.
Vehicle still at dealers whilst Jeep Aust make up their minds what to do. I have a loan Camry (Wahoo).
I will keep you posted as this story progresses.
PS Spent a lot of time on the internet boning up on EGR...these little suckers can be really troublesome, especially in some makes. I have been on the Jeep forums for the past 2 years (this is my second WK2), I have never read of a problem similar to this.
Barry

Time now to update on the saga of the dead diesel !!
I have solved the problem !!!! I am now driving a 2013 plated (brand new) Overland ! I traded the red/beige limited in on a PETROL 3.6 Overland, got a good deal.
The Limited is still in bits, no work done for some 3 weeks, they are awaiting parts. (Its been in doc some 6 weeks)
I doubt I would have ever trusted the vehicle after this episode, and frankly, the technology in this current CRD worries me. To have a system that needs "burning off" every now and then, is a crazy impost on owners in this day and age. Couple this with the EGR issue, and we have a potential for TROUBLE. The words "limp mode" appear all to frequently.This is not satisfactory in this day and age (in my humble opinion) We had TWO diesels, tilt trayed in whilst I was purchasing my new beastie.
Thus the petrol ! Sure , it uses a little more fuel (about 25 %) but I believe I have one important asset, RELIABILITY
Fingers crossed. A big trip later this week.
Barry

I'm guessing yours is a MY14, but could you tell me which model and the build date. I have Limited built in Sept and spec sheet says it has an alarm but I can't get a sound out of it. I've tried shaking it, and being locked in the front and back seats but still nothing.

Barry,

Sorry to hear about the dead diesel and congrats on the new petrol.

How was your experience with Woodleys?

Good dealer let down by Jeep Aus or both parties to blame.

How's the driving experience vs the diesel with the new beastie?

Cheers,
Chris

Re: 2014 Grand Cherokee information - Australia

Update on sorting out my Jeep

On advice from Jeep Aus, I took the Jeep back to the dealer I originally purchased from to have another look at the reversing camera. I figured it would be another wasted day as we all know it is the quality of the unit not the way it was fitted.

Anyway, when I picked up the car I had a few, hopefully positive, surprises. The dealer said that they may be able to improve the picture by a software update but apparently this takes hours so I need to book the car in again.

They said they spent a bit of time looking at the DPF to try and work out why it is not regenerating and going straight into limp mode. They reckon the DPF was assembled incorrectly from the factory and they have ordered me a complete new unit. While they were at it, they agreed that the rear shock noises were above acceptable norms so they also ordered new shocks. The previous dealer's customer rep said the shock noise is normal it is just that some customers are more fussy than others (which I took as a slight) - funny that the original dealer said otherwise as well as passengers I carry who ask "is there something loose under the car"? They will do all three in about six weeks when the parts arrive - we'll see how it all goes.

On another note, the footrest has now arrived. It looks nothing like a footrest (see picture) as I was expecting something like a dead man's pedal. I also took that into the dealer who checked the part number and had their techs look at it. Apparently it is affixed in the footwell underneath the carpet. The footrest aspect is the moulding which creates a 'bump' on which continues from the transmisstion tunnel to near the brake pedal - you can see the recess which accommodates the foot and park brake pedals when pressed. They quoted and hour to fit it.

Ok, there have been reports of head failures in the 3.6 pentastar (google pentastar head failures), but they may have fixed that. Also the gearbox is a lower spec, also read of failures in that too. But yes, it may still be more reliable than the diesel. Maybe the hemi was worth a look?

The DPF shouldn't need to be burnt off at a dealer regularly, it should do an automatic burn off while on the highway, but it seems quite a number of vehicles aren't doing it for some reason and need to be manually regenerated. A lot of manufactures have had problems with these dpf self cleaning systems, it seems something isn't right with the MY14s with this system. But I'm sure they will find a fix, eventually.

Anyway, enjoy the new one.

Yep, MY14. Its an Overland with build date July '13.

It took about 5 minutes before the alarm went off... just enough time for the missus to drift off to sleep in the back seat

Tried twice, leaving car both locked and unlocked... a nasty surprise both times!

Alarm shall only sound after it's locked (red light on dash flashes).

Alarm in Ltd is different from that in overland. To test, ask someone to stay inside back seat, lock door using FOB from outside car. Wait for car fully cycle to off, red light flash on dash. Then open back door from inside. Alarm shall go off.

Ok, I'm a bit of a mechanical dumbo so cannot use any mechanical knowledge to pass judgement but I can, at the very least, apply practability/logic. I am having trouble understanding why this "DPF" thingie causes some owners so much grief. I would have thought this DPF device would be manufactured enmasse by machines and each DPF should be identical, which is how most things are when they come off the end of machines. I am then concluding that when this car is assembled the DPF is bolted or connected up in some way or another. So if these things are identical and then fitted I am concluding that other matters are at play here. We have some observations that it is caused by some drivers not doing sufficient kilometres at high enough speeds on the highway to burn it off. But is it something else or does it simply come down to some DPF's coming off the assembly line faulty?
Now SJandL did try and find out the extent of the problem a week or two ago by asking those with problems to list themselves to gauge the size of the problem. SJandL KICKED IT OFF by listing, I think, 3 names she could think of. Unfortunately she got little response but I did think it a worthy attempt.
Anyway, I am concluding that the problem has probably "blown out of disproportion" on this site because the poor buggers affected have raised the issue many times on this site and anyone reading this forum, unless they are noting the identities of those with troubles could be forgiven for thinking it is far worse than actually is.

Trading in a diesel for the petrol....well, I can sort of understand it because of all the frustration in not having a car. It is easy for me to think WHY? because I am one who (so far) has had a good run with a faultless car....my diesel is just stunning. 7.7K/100 at 7000K, heaps of power, smooth as silk to drive. Floating on air. Why anyone would buy a Toyota is dificult to understand.

I think Webber you'd find that the DPF issues with the 2014 GC are more common than you think. The dealers here acknowledge it is an issue and when they come in on limp mode, there is a pro forma from Jeep Aus around this issue which the dealer has to fill in - seems to me a lot of effort if it were a just a few identities having the problem.

Having said that, it may well be that the majority will never have this problem. However bear in mind that there is no ryme and rhythm to this, you can't put it down to lack of country driving (as I found out) or poor fuel. It appears to be a random thing with the only common factor being that the message appears and no opportunity to do anything about it before going into limp mode. Until Jeep Aus properly sort this out by identifying the cause it should give discomfort to all CRD owners regardless if they haven't as yet experienced this problem.

As I said in the previous post, my dealer has said that my DPF was incorrectly assembled from the factory. I hope that the new one they will be fitting will fix the problem for good. I suspect thought that I might be optimistic because it seems the problem is inherent and the cause as yet unidentified, unless of-course everyone else who has this issue also has an incorrectly assembled DPF. That in itself may explain the lack of regeneration but does it explain the warning and going straight into limp mode?

Re: 2014 Grand Cherokee information - Australia

Webber. Benn0's compiled a list of those on this site that have had the DPF issue. It's in this thread - Post #9.

Is DPF issue for 2014 CRD fixed now?
