My 2014 diesel gc has gone thru the exhaust system regeneration process at least twice and i have less than 1500 miles on the car. Is that a normal interval?

Both times i have been able to continue driving like the Evic message says to do but what happens if someday i am in a position where i have to park and shut off the engine while the regeneration process is going on. Is it bad for the car?

Thanks.

So are the bigger trucks Chevy, Dodge, Ford diesels, dealing with this DEF system regen problems also?? I follow a RV forum and haven't seen any mention of it. It is just ridiculous that I'm driving an expensive 4x4 high technology vehicle and have to worry about going into limp mode at any time. I drove a 2005 Duramax for years with never a worry. If it wasn't for this I would have a lot more confidence in this Jeep.

Mazda still going and narvara still going but new jeep still at dealers for 5 weeks with no part in sight. Called them today and they said "Dont know when Chrysler will send the part". Highly skilled buck passing. No mention of a software fix. I am calling Chrysler Customer care tomorrow to ask where to from here. ie $ return, pay for car loan, magic part to arrive this week !! ??
Fortunately I have last 15 yo car still to drive and am going away os in 2 weeks so it might be ready then: my level of tactfulness is however dropping fast and a few words I didn't know are coming out during our discussions......
Started my 1965 beetle last weekend... still goes so the computer must be working.......

Hi Paul, I thought I was badly off, mine has been in since 12 December, luckily they have been providing me with a hire car all this time. Used some of those new words you are talking about. Found out that the PCM had been sent by Toll road freight from Mackay sometime after the 15th and arrived Melbourne on the 29th where it has been sitting there in a warehouse no one knew what it was there for so just left it there until I raised a stink yesterday. They were supposed to ring me back today to let me know if it had been found and the software upgrade done. They didn't. The software upgrade has been available at dealers since the 19th December and they are wondering why I am getting upset. Not Customer Care fault says customer care. Dealer didn't follow instructions. Marvellous, dealer has been ringing them each week to get the hire car extended but it didn't dawn on anybody there might have been something go wrong. I have been checking about twice weekly, but the dealer didn't bother to look into it until I wrote a forthright letter to the selling dealer with a copy to FCA customer care. I am not getting any happier by the day. Fred

It is this spare part shit that will have me leaving the brand regardless of whether or not we ever have any issues with our GC.
 
#112 ·
Yep... same here. It's a shame these tools can't manage an express air bag... especially when these are parts that should be locally stocked. Nowhere is more than 3 days away if you give a shit about your customer.

For all you guys off the road, I hope "y'all get sorted out real soon now".

Cheers,
Steve

Sent cranky letter to chrysler today by fax and got phone call in 30 mins confirming 19 dec software fix is at the dealers and officially implemented and that no parts are required to fix issue. They also said all parts are held in Victoria so will check why dealer claimed part was coming from usa.
The truth is out there......Paul
 
#114 ·
Another hour later and another call from Chrysler Customer care saying a part was still needed bec the exhaust temp sensor failed again for reasons not known. Local dealer has 4 jeeps out the back with the same fault and Chrysler is trying to blame the dealer. Part had not yet been ordered so re orderd today to arrive 17 Jan ... Strange how I can get orders from USA in 5 days ....
Chrysler now has no record of their phone calls to me 12 Dec about same issue.
They said they have requested the dealer send them a pic of the faulty part for them to view..... is this science or science fiction... their latest plan was to put a multi meter on it.... something an apprentice does 1 minute after removing usually ... I suspect these techs look at a computer readout and swap parts over and then marvel that they fail again 4 weeks later..
So no car for next three weeks.... Paul

Miscommunication seems to be very common. As I have said my part was send south by ordinary Toll Road took 9 days to get to Melbourne then nobody knew why it was there so just put it asside until I holered. Was supposed to get a call when it had left Melbourne - didn't happen. So rang the dealer and they had already rung Customer Care and have been told it was sent air express yesterday. Was to call back when received but hasn't called. Will be on the blower first thing tommorow. Very frustrating for both of us. Fred

That's good news Paul. I was in Mackay on Friday and loo and behold they had the bonnet up on my Jeep and were refitting the PCM which had just been received back from Melbourne. Apparently they did nothing to it in Melbourne, just sent it back because the December fix was better than what they intended to do to it. So they just sent it back and told the dealer to refit it, do the December upgrade and a reeburn. They did and were to send it back by tilt tray but could not get one before they closed. So were are to get it back on Monday the 12th which is exactly 1 month since it was taken in. Still haven't had an official reply to my letter from either the selling dealer or Jeep. It will still be a while before I trust it. Fred

Make sure the dealer knows about Dec update bec I had to tell them… I know its unbelievable … They will want to do a diesel burn to reset the computer, can't see why bec they all agree the exhaust is not blocked….
My GC still going well and has done 2000 k since I got it back last month.
I see our diesel engine is the same motor as the Maserati Ghibli and the Dodge Ram. VM Motori must be doing something right… Paul

I was in the same position, I rang the dealer In Warrnambool and he did not know about the fix, he then looked it up and, guess what, he found the fix.

The grand Cherokee is a good vehicle but, I think they are afraid to send out recall notices as it does not look good, it was the same with the fix for the rear shockers, no recall notice I found out about it through reading the motoring section of the paper ??
 
#123 ·
It doesn't have to be a recall. All it takes is someone to sit down with their database and ring owners asking them if they'd like to come in for improvements to be applied prior to their next service. The problem is lack of proactive action, and really, a lack of interest in knowing the vehicles they service.

No one takes any interest in what they do these days.

Cheers,
Steve

I agree about the lack of interest in knowing the vehicles they service - as quoted on the "Is the DPF fixed" thread some of them do not even know the basics as fireball has stated below.

Go outside in the pissing rain to check my dipstick, sure enough oil level beyond the highest of the dipstick :(

rang them back and blasted them

i kindly tell them the my13 takes 8.4litre but my14 takes 7.7l and that is dry .
not sure if they drained it and put castrol in now since they gave me back my bottle but with castrol. no apology for waste of time. tell them castrol isn't approved by jeep but the guy has no idea what I'm rattling on about/QUOTE

People taking delivery of a 2015 GC, are they getting the December fix? Or do they have to wait for a problem, bring it in and get it fixed? Or are people in the know demanding the fix before they take delivery? Or was Chrysler smart enough to implement the fix and anyone taking delivery of a 2015 has the December fix? Sorry for all the questions but............. I had a similar problem with Jeep years ago. I went to take delivery and asked if they re-flashed the computer for a documented issue, and later found they only do the flash if a customer complained. I told them to do it or I wasn't taking title. Hopefully things changed but I doubt it.
 
#126 ·
The 2015's have the new CAT installed, not even sure they need the Rev E update...I wonder if that REV was not just to delay the old CAT to fail later than sooner...this way, exchanges are made on a longer period....sucks to be an ECO Diesel 2014 right now! Well early build! LMAO....hey, I totally luv my GC, just want a new ReGen system! :D

That is fine if you are near a service dcepartment - but if you are like many others when it happens on a Friday afternoon and has to be towed some distance to a dealer then it won't go until the Monday and then it has to be brought back. The service department I have been dealing with is fine but being our only motor vehicle, Jeep Assist won't authorise a hire car unless you are more than 100k from your home. Also Jeep Customer Service won't authorise one until it has been looked at by a dealer. So if the December fix is really a fix why don't they recall them all and then the dealers will be on notice to do the update and the customer will not have to wait for the bomb to go off. It is called "CUSTOMER SERVICE"

Hello I need some clarification. I have a 2015 that I took delivery in early February. I was driving the other day and got the message "regeneration in progress continue driving" I looked up the messages in the diesel supplement for the DID on this system and it doesn't have this message. The message in the supplement are as follows:
Exhaust Filter XX% Full Safely Drive at Highway
Speeds to Remedy

Exhaust System — Regeneration In Process Exhaust
Filter XX% Full —

Regeneration Completed

Exhaust Service Required — See Dealer Now

Exhaust Filter Full — Power Reduced See Dealer

So my message didn't have anything about the percent full of my DPF filter. So I continued drive for about 8 minutes got to my destination. When I restarted the car the message was gone. According to the book (which does not explain this message) and this website, I should of got the regen message again when I started home then a regen complete. Well my assumption was it probably burned off enough particulate so it never got back into regen. So what is this message? Why is it not explained in the book? Is this a normal regen? Why didn't the message read the % full or tell me regen was complete? Anyone know what's going on, I could use the help. Thank You Mike

Its the software fault which reads the exhaust temp range incorrectly and thinks its got a blocked exhaust and werent let cruise control switch on.
I got the fix 15 jan15 after three flatbed events, 2 unnecessary sensor replacements, 6 weeks in dealers while they argued with chrysler and its been fine since.
Probably, once its done 500k , the real light might come on and actually need a burn. What annoyed me was so called real mechanics telling me at 6000k the exhaust was blocked. Paul

Grandhaze, The Australian export CRD's are inherently different than the NA ones and have had some major issues with DPF regens. The NA ones seem not to suffer from these issues and have very few cases of severe DPF regen problems. Your response might not be relevant for all as I'm not sure mbaessler is from that region. In the MY14 NA models, if you got any DPF related message on the EVIC, it was not a software issue and it truly indicated that your DPF is unusually clogged and you MUST drive at highway speeds as last resort before limp mode kicks in. I'm not sure if Jeep brought level 2 regens to EVIC awareness in the 2015 model. If there are any 2015 owners that use OBD to monitor regens, they might be able to chime in and indicate if those are now showing in EVIC.
 
#134 ·
Yes the Australian models are different. The fault comes up with "blocked exhaust , drive at highway speeds" and then puts car into limp mode at the same time !!!.
Seems the different models share enough computer software to confuse themselves about whats happening. Mine has been fine for 5000k now, still waiting for recall four about the steering computer upsetting the abs computer… Licence plate "Recall" staying on….Paul

I have 39,543 miles and never before got this, until yesterday. I've always done a little highway driving each tankful, but then for about 1+ tankfuls I did only in town, local driving.

I took pictures as I got the messages. I won't include them but they captured the mileage and messages. It took 25 miles to clear.

I am in the USA - CA near San Francisco.

39,543: Exhaust System Regeneration in Process Continue Driving (while driving to errand)
39,546: Exhaust System Regeneration in Process Continue Driving (after errand, on restart, so I went driving)
39,549: Exhaust Filter Nearing Full Safely Drive at Highway Speeds to Remedy (drove onto the highway)
39,550: Exhaust System Regeneration in Process Continue Driving
39,556: Exhaust Filter Nearing Full Safely Drive at Highway Speeds to Remedy
39,557: Exhaust System Regeneration in Process Continue Driving
39,568: Exhaust System Regeneration in Process Continue Driving (arrived at destination, parked, engine off)
39,568: (on restart; no more messages)
 
#136 ·
I wouldn't have turned off your Jeep lol. That message appears on stock vehicles when the filter approaches 80%. It normally doesn't have to because the passive regenerations occur at 65%. If the passive ones get interrupted enough, the message appears as it approaches 80%.

Im sitting at home having just put my Jgc 2014 on a tilt tray after 33680km of trouble free driving, no warning just came up with the drive at freeway speeds and it promptly slowed to 60km/hr and 3rd gear. My foot flat to the boards locked in 3rd... Misses is realy pissed and i cant blame her, i love the car but hate the feeling of living 50km from the only dealer in cairns, my family is now stuck with no wheels and im sure im not the only one... come on Jeep! Fix this shit once and forever...

THIS. This is why last weekend we traded in my beloved SFU for our first-ever minivan. Having to tow a JEEP TWICE in 2 years because of exhaust treatment issues caused a complete loss of faith, and my wife wouldn't drive it without me.

Between this, the RAM issues, and VW, I'm not so sure we 'Mericans will have passenger Diesel options much longer...
