G'Day all,

I've read a ton of threads here that mention the DPF and "Limp Mode" dramas with the 2014 CRD, but they don't actually confirm if the DPF issue in Australia is actually fixed now. Apologies if the fix has been mentioned here, but I can't find that thread.

After many months of working extremely hard to convince the "hugs & kisses" that the 2014 (or 2015) Jeep Grand Cherokee WILL be much more reliable than our previous 2000 WJ-Limited V8, I'd hate for the DPF issue to crop up with the new JGC.

If the DPF Limp Mode happens to my wife while I'm working interstate, it will not be pretty, and I will be in more trouble than Ned Kelly :eek:

To be safe should I go with the HEMI? Apart from a higher fuel usage rate, it isn't hampered by the "apparent" CRD's DPF problem.

Any comments, recommendations or reassurances are greatly appreciated.

Cheers,

Marty

You should not need any additives to control the DPF issue.
The problem is with the car components and possibly with the computer program.

All you need to do is use good quality fuel, and the correct specification oil.
Jeep will 'eventually' resolve the issue, so that burning off the soot is done when required, as opposed to throwing a warning, then immediately going into limp mode.

Spoke to the local Jeep dealer today.Not the place i bought my Jeep from.

I asked him about the DPF issues (which i haven't had )and he addmited they had some with the problem and one back twice but he informed me they had a fix now and it is a new flash and it was all computer related.
You could work out the dealership by the town i live in a give them a ring if you won't more information.It sounds like you only get the flash if your having a problem.

I've just finished reading the 2014 GC "EcoDiesel OWNERS!!! Review thread here, .....and WOW!

There are pages and pages of nothing but good to great comments about the 3.0l Diesel by CRD owners.

I do feel bad to those that have experienced the DPF issue, and I do hope they get it fixed very soon, however there appears to be a vast majority of CRD owners that have had no DPF issues at all :thumbsup:

The US owners don't appear to be having this issue, but their electronics are a bit different, and they use DEF, not sure if that has any impact....

The DPF problems seem to apply to the MY14, those with the older models seem to be ok. Hopefully the flash update has done the trick....

Actually my wife just got hit with this issue on her way to work today (Western US - Idaho). The warning came up yesterday so she drop approx 25 miles at 55-65mph last night. She got no more than 5 miles this morning when it locked down and she had to drive 30-35mph to the dealer (25 miles away).

She was not very happy. I sure hope this is a software issue.

Thanks.

Aaawwwwww :mad: If this happened to my wife while I was interstate for business I would never, EVER, hear the end of it.

After our forgetful experience of the WJ (2000 - Limited V8) JGC ownership, I have finally got my wife convinced into purchasing another JGC because, "Jeep have improved in all areas now compared to our 'ol WJ honey!.... Ya gotta believe me....... They're great, reliable cars now!"

But how can I risk what has just happened to Vorpel? It would be the end of my life as I know it :(

I understand and appreciate that when running properly the CRD is a brilliant engine. However this DPF "issue".... well??? ...I may have to go with the 5.7 HEMI and visit the Petrol Station more often; just for piece of mind :(

All,

Have just finished reading an article in the April/May issue of " Caravan & RV" re there Overland Diesel tow vehicle suffering the DPF full limp home scenario.

The articles author also makes mention of Fiat Chrysler Australia's (FCA) vague response to his (I guess) request for comment.

If there is a 'Flash' that solves this DPF no warning issue, don't you think FCA would have mentioned it in their response to the authors enquiry?

Do FCA even know what the state of play is with their public relations profile resulting from their failure to respond appropriately to there paying customers concerns?

It smacks of an attitude something like "We have your money, stop bothering us. We are too busy selling more faulty (and in this case dangerous) JGC's"

Just to provide a positive view for those contemplating a purchase (I don't disagree with some of the points made and was one of the first to suffer the DPF Issue and require a forced regeneration)....

Just returned from almost 3400km outback Western Queensland trip towing my dual axle 2.7tonne Jayco Starcraft.
2200km of that towing.
Average overall 13.5l/100km.

Car issues - none!

Went very well. No problems. Tight as a drum except for a creak I have put down to the rear 'spoiler' over the window.

Touch wood, the car was excellent and after many hours of removing the dust, looks like new again.

Cheers
Andrew

Yep, thanks for the update, not hearing many negatives on the dpf issue now.... fingers crossed while knocking on wood.

Just makes it easier for people to find info when it is in the right thread.... and prevents other threads from getting filled up with irrelevant discussion.

I towed in all three modes and I'd have to say it didn't seem to make much difference. (This should probably now move to the towing thread).

What I can say is that at the 93km/h that I typically drove at on the single lands roads (with no shoulder) of western Qld the car sat in 7th gear almost all the time.

Moving up to smoother, wider roads and the speed closer to 100km/h it would move to 8th and get slight better fuel economy.

Up the long Toowoomba range the transmission and engine got hot (I think all cars do - they just don't have 'honest' gauges that show a 10 - 20 degree difference) but the car managed it all with aplomb. No issues at all - of course it got hot.

Cheers
Andrew.

I think the reason this issue has gone quiet on the forum is there are a number of vehicles sitting in dealers yards waiting on replacement DPF filters to arrive ex US, mine being one, part should be in Cairns next week. From what I'm hearing this issue is far from resolved. No ones saying much, still the old "we don't know yet".

It appears to me from the couple of failures I encountered that the system was failing to do either a passive or an active regen, basically into "limp home mode" with little or no warning, hence the filter so badly blocked it has to be replaced. This Jeep had done very minimal slow speed short runs, mainly highway and towing a boat some distance. Sounds to me more a sensor/software/mapping problem.
Will keep you posted of the outcome next week,
Cheers,

Here's an update, I see that Nicko has had a replacement ordered, was there another owner with a replacement?

Missionman Filter nearly full message then limp mode despite recent highway driving (2 occurences)
Fatboy Exhaust system required message my13 trailhawk
Fireball Filter nearly full message then limp mode despite being at highway speed 1900kms Nov 2013
Chooke Filter nearly full message then limp mode despite being at highway speed May 2013 (2 occurences)
Peanut Filter nearly full message then limp mode. (2 occurences, Jeep is replacing dpf)
Twscoot Filter nearly full message then limp mode despite recent highway driving 6000kms April 13 (No problems since manual burn)
ansamoiz filter nearly full message but couldn't get to a highway before limp mode kicked in 4189kms July 2013
mbro filter nearly full message but couldn't get to a highway before limp mode kicked in 1300kms Dec 2013?
A10-6 filter nearly full message but couldn't get to a highway before limp mode kicked in 1600kms July 2013
Dreamer filter nearly full message but couldn't get to a highway before limp mode kicked in 14,000kms April 13
fforacing Filter nearly full message then limp mode despite recent highway driving 6,500kms June 13
gsw80 Went straight into limp mode despite highway driving 7,500kms June 2013
Jarrid filter nearly full message but couldn't get to a highway before limp mode kicked in 17,000kms July 2013
Nicko limp mode with no warning 8,000kms June 2013 (2 Occurences, replacement DPF ordered)
nmcglynn Filter nearly full message then limp mode despite recent highway driving 2800kms (2 occurences, Jeep is replacing dpf)
burger Filter 100% then limp mode, no warnings 16,500kms April 2013 (EVIC has no recorded burns!)

So a member over at AJOR has a brother who had 2 DPF limp modes despite highway driving, on the 2nd occasion the dpf wouldn't clear with a forced regen. Must have been something jammed in there. So Jeep Oz got them to order a new DPF and that seems to have fixed it. It was Sept 2013 build.

>>>>>>>

Seems to me there are a few issues here, some of those who have had manual burns have been fine.... so far. Others have had reoccurences and in which case either the flash gets applied, or the dealer orders a new DPF. In one of those cases the manual regen failed to clear the blockage, wonder if this is what happened with Nickos?

Our Limited went into limp home mode on Sunday, wife rang roadside, car was towed to dealer on Tuesday where they performed a manual regen. Car returned on Tuesday afternoon after some confusion with the service reception (was told ours needed a new ECU!!!. Turned out to be someone elses thankfully). Wife has taken it to Cairns for the weekend with no further issues (fingers crossed).

Update - Dealership did a manual regen and that cleared the issue. Service rep told me that he believed it was a software issue, and they updated everything. This was our first service since taking it home back in mid November (also did tire rotation and oil change).

It isn't a fun experience, but to me (and my wife) it is so outweighed by all the positives. Lately with 60/40 highway/stop & go traffic we have been getting 25.5mpg. When we do 80/20 it goes up to 27mpg. You just can't beat that mileage with that towing capability with that luxury (Summit). No regrets at all.

Good luck, and hopefully it was just a software issue...!

We have clocked up a total so far of 2,000 klms towing our 2.9 Tonne Futuresystem caravan with our new Laredo.
Our (all towing) average is just a whisker over 13 litres per hundred klms, fully confirmed by my calculations at time of filling. I know I could do better in flat country, if I watched my speed a bit more.

Verdict on the new Tug so far?
10/10, absolutely delighted. Not a squeak, not a rattle, not a squawk, totally delighted with everything.
I think it did a regen at about 300 klms on the clock (before any towing), with an otherwise inexplicable increase in instantaneous fuel consumption for a while on the highway, (though no messages), probably as a result of delivery idling etc. No hint since then of any regen or of any DPF issues.
Early days yet, but delighted so far.:thumbsup:

Hey guys and gals,
I have been searching through your forum endless times in search of some info regarding the issues with my 2013 build Limited Diesel.. I am astounded to see that I'm not alone! So I've decided to join :).

The first time our Jeep went into limp mode was not long after we had returned from a 4 hr drive to Whitsundays. I'm not entirely sure whether this had anything to do with the issue, but I feel like it certainly plays a part somewhere.. My wife drives the car daily for 20-25mins on the highway at 100km's each way to work everyday. so I figured that would be a great burn off period! The msg that was displayed what something like "Exhaust filter nearing full, drive at highway speeds to remedy". (wife was driving) next time she jumped in the car it was locked into 4th gear.

Upon returning from work a few days later I took the car in to Jeep service centre and they were quite happy to fix it, and knew what the issue was. I was bombarded with a horde of Q/S's in relation on how we drive, where to, what fuel do we use etc etc.. I started to think maybe this is a manufacturing issue with all these problems!?! (and just adding to the list of issues, the cruise control only works sparingly, and the aircon also has a mind of its own on some occasions.)

When I returned to pick the car up, I was told the cruise/aircon wasn't fixed, as they had been having problems with the DPF! they asked to keep the car over the wk end to continue work (Mothers Day wk end mind you) which I said No too. They said they could force a regen, which I agreed too. When I finally got the car, the service advisor then told me that this was in no doubt going to happen AGAIN, and they couldn't tell me when, or even replace the filter.

The car at that stage had about 6500 km's, and now has about 8800km's.

I really hope we don't have this issue again, as I do love this car..
sorry for the rant!
thanks for reading!

Is your car a 2013 built MY14?

In some cases performing a manual regen does fix the problem, but SOME owners have seen the problem re-occur after a manual regen.

With the amount of highway driving you do it should be triggering an automatic regen during one of these trips, but some owners have found that even when the car tells them it wants to perform a regen and they drive at highway speeds, it doesn't work.

Some owners have had to get the filter replaced, but there has also been a technical advisory released on this issue, which involves a software update to make the car perform the regen correctly.

http://www.wk2jeeps.com/tsb/tsb_wk2_1801814b.pdf

There have been differing responses from dealers about whether this TSB applies or not, but worth raising with them.
 
#245 ·
Thanks for your reply! Yes, it is a October Built 2013 MY14 Limited. Sadly, over the long weekend we have suffered another DPF Limp mode.. My wife was driving at highway speeds when the message "Exhaust filter nearing full, drive at highway speeds to remedy" again. she was coming up to a red light, and when she took off again it was locked in 4th:mad:. I have been on the phone to the service department again, but no one wants to call me back - or give me any answers.
 
#246 ·
Ok, well if it has re-occurred shortly after a manual regen I'd be asking them to replace it. It can be quite a wait for a replacement.
