You're correct. It was regening. No consequences, it'll take up where it left off.

Remember the EVIC will only alert if the DPF is getting stopped up.

I have nearly 1400 miles on mine, I've never seen any message yet, but I also drive 33 miles on the highway to work each day and very little stop and go. So far I LOVE this vehicle!

Sorry to bring this thread back from the dead, but I thought I would just throw out my opinion on the re-gen process, I also posted in the re-gen thread in Jeep Garage. I am a new diesel enthusiast, right now I have a 2013 Passat TDI. And from what I have learned in my short time about regenerations is that you should avoid interrupting them just as you should avoid the black plague. lol. From what I understand, during a re-gen, the turbo is extremely hot just as is the DPF itself, and for you to just turn off your vehicle with the turbo at that temperature assuming 1000+ degrees F, there should be a concern of oil coking within the turbo, which is def. not good for the longevity of the turbo. And I understand a re-gen may occur at an inopportune time, like your late for work, the re-gen is still occurring once you arrive at work, but don't have time to wait for the car to finish its re-gen cycle and you need to turn off the vehicle. Hopefully these type of occurrences are minimal. But I feel a word of caution should be thrown out there, it is bad to turn off the vehicle during a re-gen, due to oil coking within the turbo. The vehicle should be left running to keep that oil and coolant running thru the engine and turbo especially. Just my .02 cents.

We have a Grand Cherokee Turbo Diesel with just about 5000 miles on it. Ours goes through the regen process ALL THE TIME. The latest incarnation I was on a road trip and drove 90 miles at 70mph and the message kept coming back saying to drive highway speeds to remedy. 2 days later I drove home (the car was not used for the 2 days) and it got another 90 miles at 70mph and the message still kept popping up. Obviously it shouldn't take more than 90 miles to remedy itself! The next day, when my husband tried to drive it, it eventually told him that he was not permitted to drive over 30mph (interesting, considering the previous message said to go highway speeds). It actually physcially would not allow the vehicle to go over 30mph. So, it's taken the slow <30mph drive to the shop. It also threw 2 check engine codes about losing communication with the ABS system.....and some other "lost communication" error that I can't remember. Needless to say I am not thrilled about my 6 month old car already being sidelined. I love the car but I fear reliability it going to be an issue with this thing!

Ours has just over 10k on it. The same exact thing happened where the exhaust filter filled up and put the Jeep in "limp mode". Jeep has a rapid response notification out to the dealers for this issue. They needed to apply a software update to the PCM module and run the vehicle thru 2 regen cycles. Call your dealer and let them know this if they aren't already aware. I just got ours back last night and so far it is fine. They put almost 30 miles on it to complete the regens though.

My Jeep has the V6, but my pickup has a diesel and the regen always happens at the wrong time. This is one of the reasons that this will be my last diesel pick up.

I have a 14 diesel, and have 12000 miles on it since March. My miles are mostly highway, with most of them accumulated on my 850 mile commute at 75mph. Twice now I have made the 850 mile drive and had the message pop up the very next day, telling me that it is not very smart about its regen timing and that it's not regenerating constantly while I'm on the highway.

Just my experience.

I've gone through about 12 gallons of the DEF so far or roughly 1gal:1000miles, but my dealer also delivered it 25%full, so actual usage is closer to 1:1500

Apparently there was a "required software update" that caused our exhaust system to crap out. Completely ridiculous. If a software update is so important that it can result in the car going into limp mode and essentially become incapacitated in the middle of driving then it should be a RECALL. How else am I supposed to know about it? I had the car in to the Jeep Dealer for an oil change about 7-10 days prior and they didn't say anything! They didn't even know what to do when we brought the car in after limp mode. They transferred the car over to the Dodge dealership to fix it. From now on I will be doing directly to the Dodge Dealership.

hi guys, I'm from Australia and my 2 month old 2014 grand cherokee limited diesel has randomly come up with this same message.. i was driving normally and it appeared "exhaust filter nearing full, drive at highway speeds to remedy" only problem was that as soon as i saw the message my car went into limp mode, stuck in 3rd gear and with my foot down would not exceed 65km/h...so how is it possible for me to start the regen process if my car won't even reach highway speeds? i will probably go see my dealer tomorrow, but is there any quick fix for this at home? thanks

Same problem.

I have had the same problem with my 2014 GC. This is the third time I have had to return it to the dealer because it's in limp mode. I haven't gone through a tank of diesel yet and it seems to happen after a week. I'm starting to regret buying this vehicle. I'm also in Australia.

Are you the same guy who described this on Facebook, or are there more cases?

I'm following the common theme here, have had my '14 diesel GC Limited since July, just hit 4,700 miles, have loved everything about it...until....yesterday I had the same "Exhaust filter nearing full" message pop up for the first time.

Didn't know anything about these issues prior. Literally drove 10 miles in gridlock traffic and stopped at an appt. for an hour. When I started driving again, within 5 minutes the car went into limp mode and I topped out at 37 mph for all the 25 miles to the dealer. They didn't know anything about any software updates so I am really curious if they are truly going to develop a better advanced notice of this as I had no chance to regen.

They did mention the idling and cold weather doesn't help the problem as it is about 12 degrees here in Chicago and I do a lot of driving in traffic. Although I just did a 350 mile highway trip the week prior which surely had to kick in the regen process. Regardless, I am getting extremely nervous that this can be a reoccurring problem considering the cold and traffic conditions here.

I will keep my eye on this thread so any answers that people are receiving, please post as my dealer had no grand answers on anything coming down from Jeep. Thanks

Interesting these comments on the regeneration process. We have two 2014 EcoDiesels, both with over 11K miles on them now, and in neither of them has this message occurred. We do however drive a fair bit on the highway so perhaps that's why.

The less you let the diesel idle, the fewer times it will need to clean the filter. Until it needs cleaning, it will not go through a regen cycle, thus why it sometimes will happen right after you get off the road from a long trip

Faulty DPF

Mine was a faulty DPF on a new car! If only I had researched it further. The salesman told me it was Canadian built. It's Canadian designed and built by Yanks. I thought that being owned by Fiat they would have a reasonable international quality system by now, but obviously not.

They replaced the DPF after taking it in on limp mode three times in a row. Hopefully this will be the last problem. My next car will be Japanese. I can't afford to wait around for nearly three weeks while Jeep make up their mind then finally airfreight the part from the US. The dealer said it was a $5000 part. It would have cost them nothing if they'd got it right first time.

One fault in every 300 cars is too much. From what I can see, that's the failure rate.
