2014 Diesel Grand Cherokee exhaust filter issues...

I moved into a 2014 Grand Cherokee Overland Diesel in December, 2013. So far I love the vehicle...except for one thing. Twice in its first 6400 miles (first at 3200 then again at 6400) the display told me that the exhaust filter was nearly full and to drive at highway speeds to recycle it. Within 6 hours of the warning coming up the vehicle was in limp home mode, barely making 20 mph, despite having driven it at highway speeds as instructed. Has anyone else had this problem? The dealership told me that I need to drive it over an hour to just start the regeneration process with the filter, and then drive it some more to accomplish it. I simply don't drive on the highway that far on a daily or even weekly basis and as such I'm going to be subject to this problem over and over again I would expect. Anyone have a solution? Love the car, but hate this problem.

  • As a follow up to the above post I contacted Jeep regarding this issue. They were very nice there and promised a response. Yesterday I got that response, which was basically "read the diesel supplement in your owner's manual." That didn't really help. I have had the vehicle go down twice. I want to know how often I need to drive on the highway to throw the filter int regen mode. How far, how long, how fast, how often??? They didn't answer these questions and apparently do not have anyone available to call me with the answer. I'm more than a little disappointed. The first two times the problem developed very close to my home, and close to 3 different Jeep dealerships. The next time I may be in upstate NH or rural PA nowhere near a dealer. It's not a good feeling when you can't depend on your vehicle. Any info other forum readers may have would be welcome.

    Regeneration occurs most effectively at highway speeds to prevent excessive heat buildup. While it seems odd, it really is necessary to go for a highway run of about an hour (at the speed limit, nothing crazy) at least weekly to allow a full regen to occur. It's an unfortunate fact of life for new diesels. Waiting until the dash warning appears can be too late, as you've experienced, and limp mode is required by law in this case.

    The last 5000 miles I have only taken one trip with an hour plus on the highway in my 2013 Touareg TDI. And that was stop and go through Los Angeles. I think Jeep needs to go back to the drawing board or tell people up front the JGC is a highway only vehicle. Having a shut down way back in the wilderness could be deadly. And that is what Jeeps are designed for off road travel. I hope Jeep has not built another diesel like the last one. Many owners spent long hours in the shop. It does nothing to enhance the many advantages of diesel vehicles. Have their been any such complaints from the MB, BMW or VW diesel owners?

  • I am having the same issue at 7600 mms.  Drove on highway for 1 hr still have the warning?  Any advice? I am concerned vehicle will go into limp mode. How do you get vehicle out of limp?

    i have a 2014 jeep diesel. the driving at 60 mph for an hour is BS. i drive weekends regularly upstate and the filter still fills up. every 6 months these filters need to be replaced or you go into limp mode. nothing we can do. these cars are lemons as far as i am concerned. in my 43 years of driving, never have i had a car that i cannot depend on. they kept this from us on purpose. otherwise, the car is great.


  • I have the same issue with my 2014 Grand Cherokee Diesel. the error message came up , i went to the dealer who told me that i needed an oil & filter change, fuel & air filter changed, the DPF regenerated and no ne of it covered by warranty, Cost was $1700.00 ++ My vehicle has 24,500 miles on it, How Can this be? i want to go after these Bastards with the lemon law, Can Anyone Help me or Guide Me how to resolve this Issue????

    I also own a 2014 grand jeep Cherokee diesel , I also had dpf troubles but I own my own scan tool to carry out the regen when needed, however it has not been a problem since I changed to a grade of oil made here in Australia called Penrite. This company has made a high quality diesel oil to counteract PDF problems. Servicing is very important with modern Diesel engines but short driving cycles does bring on problems in all types of vehicles not just diesels. Add PDF cleaner to your diesel fuel regularly this helps dramatically in cold climates to keep the dpf clean. Premium diesel fuel also helps counteract dpf issues .hope this helps
