Need help from experience diesel owners

Looking at buying a JGC ecodiesel 2014 or 2015.

What are the problems that these cars have had and have they been fixed?

Should I stay away from a certain build date?

Does 4x4 or 4x2 have any concerns when getting a diesel?

Should I buy off the lot or build it and order it ( if the latter, how long does this typically take)

Any other advice would be appreciated.

Subscribed.

I came here with the same questions which I punched into a search engine. I did a search online for problems with the engine. It lead me here and to a few other sites.

These threads might be of interest to you:

Incorrect DEF - See dealer

oil catch can

Any way to block the EGR?

The problem with doing this type of research online is this, you really have no idea what the % of people having problems is. People tend to join sites when they have a problem, to vent, or look for a solution. Satisfied people who have no interest in message boards go about their lives happy with their vehicles and not posting about them. Bottom line is the % of people having problems could be minute, but searching for them on the web can blow the % out of proportion. HTH

Re: Need help from experience diesel owners

My 19 DEC 14 build has been excellent. Had a few updates done and no issues. One oil change and on 15000 miles. Love it best vehicle ever. I see no point in buying a Jeep if you get 2WD. Might as well get a better vehicle if that is what you want. My 4WD averages 28 mpg or better if less than 70 mph and in town 23-25 mpg. Last diesel I bought here in the Florida Panhandle was $2.59 gal...

Re: Need help from experience diesel owners

I went 4x2, drove almost 30k miles last year, it wasn't great in 18" snowfall but didn't get stuck once, traction control was on constantly. So 4x4 necessary, not exactly. Would help resale.

Re: Need help from experience diesel owners

4wd will help resale value if you live anywhere the weather can get bad (aside from rain / flooding). The majority of us do not have a lot of issues (just some overall quality control) with the diesel. I'm at 17k now and bought it in April '14. Mpg is excellent - nothing in it's class even come close unless it has a diesel (then you have to go German and spend much more). I get better mpg than my Crosstrek XV (it has a manual though) and most cute utes with 4 cylinder engines. The diesel Jeep is a bargain in the industry - FCA needs to get their act together to get dealers up to speed on fixing some of the teething issues though.

BTW - this is my 2nd diesel Jeep (had a '07 before and loved it - even though there were issues with it as well - but a well educated community is on here and I created some Jeep Diesel FAQs you can find on google). The WK2 FAQ is very out of date as I've not had time or the issues several others have had so had no need to really find out what's wrong.

My dealer told me that they only get 1-2 diesels a month which sell immediately, and that most of their diesels are ordered from the factory like mine. I waited 12 weeks to the day for mine and that was apparently unheard of, though some other guys in the delivery thread waited just as long.

I can't fathom getting a 4x2 diesel GC considering the negligible mpg hit and the price point you're already at. Off the lot maybe if its an extremely good price, but if you're ordering then kit it out.

Re: Need help from experience diesel owners

Except for a transmission reprogram and minor radio head unit reprogram, the 2015's have been pretty trouble free. They've not got a long track record since they've only been out a few months, though. Pretty much like any new vehicle in that regard.

I only have about 400 miles on my 2015 ecodiesel, so I have limited experience.

My one suggestion is to get the DEF injector plate and get it installed first thing. About $200 will save you big headaches and get you into a solid vehicle. Otherwise, watch out for puddles, snow, and twigs. No joke.

2014 models are having issues with the catalytic converter causing P20EE codes, clogged DEF injectors, and failed DEF pumps. Not everyone seems to have these troubles, though, and it seems somewhat dependent on driving frequency/distance/style. There are also software issues in the 2014 models, but they've sorted most of that with updates. The catalytic converter is a known issue that they deal with under warranty after a lengthy multi-visit troubleshooting process. Sometimes you have to get Chrysler involved if your dealer's service manager is a dope.

Re: Need help from experience diesel owners

Any of the Ecodiesels are fine to purchase. The early 14 JGC's (gas models) had a few issues, but they were worked out before the Ecodiesels were released. I have one of the first off the line, and it runs great.

Are the 2015's using the same DEF injector, DEF pump, and Cat converter? Or were they changed as a result of the 2014 model year issues? Thanks.

My understanding is that the DEF system is the same, but the programming and CAT have been updated.

Thanks! Any word on the PCV and EGR systems, are they the same as the 2014's?

Re: Need help from experience diesel owners

We love ours but have only owned it a week. Here in TX we have no need for 4x4. I would have taken one if the great deal we had got happended to be on a 4x4 instead but it wasn't and that's fine. It's my wife's car afterall.

The only thing I find really annoying is that mine has a CD player option and I assume it's taking up a bunch of room in the center console. It's hard forme to fathom why anyone would order a vehicle with this $300 option but that's how mine came. Anyone want a factory installed CD player? I'd rather have the space.
