We purchased this GC about 3 months ago. We decided on a diesel for fuel economy because we want to do some traveling once we're able to retire. For now though, we're still working. Shortly after buying the vehicle a warning was displayed to get maintenance immediately. It was discovered the DPF was just about full. We had no knowledge about this filter and what's required! We live in a large city. My husband drives this car primarily and drives to and from work (not on an interstate highway) and then to and from golf on the weekends (on interstate highway about 20 min each way)... approx. a total of 75 miles a week. So we had the filter cleaned and were told we needed to get the vehicle to highway speeds of 55 or higher when the 80% maintenance display came on and drive it for up to 20 min. This is a nightmare for us! Anyway, sometime after this we drove to the airport (45 min drive on interstate highway) and thought... "ok, good the filter is getting cleaned out", but one week later the 80% display came on and thankfully my husband was close to the interstate. He was on his way to work when this happened and by the time he got to work he was an hour late (due to traffic he'd never have encountered otherwise). We're taking a trip to an area where driving 55 MPH and up isn't possible... small roads. What would we do if the 80% display comes up?! We did our homework prior to purchasing and didnt see anything about the DPF and it's requirements.

This is normal for all modern diesels with particulate filters.

Your use case is bad for diesel solutions.

I bought my 2016 GC a little over a month ago and do mainly city -stop and go driving. So far no issues. My dealer warned me that I would need to do periodic highway driving to clean out the filter. We take quarterly trips that require highway driving so I figured this should solve the problem for me. I also don't feather the throttle.

Just got my first Exhaust System Regeneration warning... While I fully understand that this is part of diesel engine but I was amazed it happened so soon. I only have ~1,700 miles my Jeep.

Per the manual, I needed to drive at highways speeds for about 20 minutes, which I did and the warning message went away after about 15 minutes. This was not convenient for me. Is this normal?

My daily commute is about 20 miles a day, city driving. On weekend I run errands for another 40 miles.

I have just about 32,000 miles on my 2014 and I think that the exhaust regen message has shown up maybe 5 or 6 times since I've bought it. My daily commute is much shorter than yours (2 miles each way) - it only comes on if I haven't taken the vehicle on the highway in a while, but it isn't frequent.

When that message comes up, I'm not certain what would happen if you just went about your business and turned the engine off while it is displaying it. The manual states that the message is supposed to show a percentage that the filter is full, but mine has never said that - just "Exhaust System Regeneration in Process Continue Driving" or "Exhaust Filter Nearly Full Drive Safely At Highway Speed to Remedy".

Good to know CaseyGV....

My messages said the same thing, first "Exhaust System Regeneration in Process Continue Driving" then "Exhaust Filter Nearly Full Drive Safely At Highway Speed to Remedy".

I went to the RAM Diesel Forum and they said the system does this every a lot more often but its done behind the scenes so to speak. It computer only lets you know when the filter is getting close to full.

I Drive diesel trucks for a living (ups) this regenerative filter issue, that all of you new to diesels..... is it normal... Just take it that car for a drive and save yourselves a headache.
Diesel engines are good engines if they are driven! The problems occur when the are stored and driven around the block.

Been using Banks IDash for while, which tells me when behind scenes regen happens. Drive mostly freeway, behind scenes regen happens about every 150 miles. Since I drive mostly freeway, never have had full regen message in 16,000 miles.

I need to buy one of those...

Question for the group: Is there a way to for me to start a Exhaust System Regeneration? If not is there something that I buy that will. My logic is, if I can start a Exhaust System Regeneration, I would do it on the weekend when I have time to hit the highway.

I have a 2014 GC Diesel Overland........it has about 26k miles on it. My wife mainly drives it and has been complaining that it smokes. I've taken it back to the dealership 5 times to figure out and they can't get it to smoke. I finally talked to GM and he drove it and got it to smoke. Seems a def valve was corroded and causing the problem. Had to contact Chrysler to figure out. Still waiting after them having car for a week. Very frustrating. Otherwise its a great vehicle. Just not right to pay that much for a car and have it smoke. Anyone else had this problem?

I have a small business that cleans DPF's and DOC's for over the road trucks as well as light duty diesels. I have found that hardly anyone, including dealer service departments, understand how a DPF functions and what "re-gen" really does. Here's the deal. The Diesel Particulate Filter (DPF) traps the particulates in the exhaust and prevents them from going into the atmosphere. They eventually fill the DPF up at which time it needs to be cleaned, not re-generated. Re-generation occurs when the amount of soot builds up and causes a back pressure problem, then the re-gen process burns the soot up creating ash that is trapped.

Want to prevent big problems, then don't ever idle for long periods and do run it at highways speeds as much as possible.

Yes- that was brought up on earlier posts about 'excessive idling'. When I brought mine in for the gear shift recall- the service manager mentioned that is the only problem that usually occurs on 'commercial users' of Ram pickups- and they make it a point to tell them not to 'idle them for excessive times'.
