Hello,

I am looking into getting a used diesel grand Cherokee (2016-2019) preferably 4*4. I love the idea of its fuel economy and towing ability.

What issues, if any should I be wary of? What can I do to make sure that I don't buy a Jeep with issues? When I inquired about one the guy said it had an extended 1 year warranty because of some lemon law issue. Which, needless to say, was concerning.

All your input and advice is very much appreciated.

Many thanks,

J.R.

I have a 2014 that I bought brand new. I do love the fuel economy and the power it has. But it has not been without problems.

What you need to look for:
* Have all the recalls been performed? (There are several over the years).
* Has the AEM been installed (that’s the emissions lawsuit stuff) and have any subsequent issues been addressed? I had many parts replaced after this was done (but all covered by warranty).
* Has all the scheduled maintenance been done on time?
* Does your local dealer know how to maintain it?

Every time I have had my vehicle in the shop, they’ve needed it for a week or more. The last time I was in for service after the AEM, for the fourth return visit due to a recurring Check Engine light issue, the service advisor there told me to replace it with a gasoline one that everyone knows how to work on.

That being said, after the latest round of work done this past summer, after getting through the issues after the AEM, it has been running fine, including a 1500 mile road trip.

Definitely make sure you understand the terms of the extended warranty provided by the lawsuit, but make sure the vehicle you are considering has it. (If the person who owned it did not have the AEM installed, the warranty is not in effect).

I own a 2014 GC Diesel (175K) & a "cooler" hose just went. Oil went into the coolant system b/c of ruptured hose, everything will have to be flushed, estimated cost to fix $6,300. I took great care of my jeep however, I would not purchase this diesel jeep again. I feel like Chrylser searched for "something" not covered under the warranty recall (I had the AEM installed) until they found the "problem."

Check engine light kept coming on after the AEM install, took to dealership but they didn't understand why & reset the check engine light. I'm not a Motörhead/car guy however, I take care of my things/cars. I expected to get 300K+ miles out of this vehicle. If I were anyone w/ this jeep getting up there in mileage, I would trade it in before sh*t hits the fan, they have your jeep @ the dealership and you are stuck debating wholesaling it for pennies while you don't have a car to drive. I have had numerous issues over the years with this Jeep, don't buy it.

Have you considered a used late model Touareg? I feel like those have had fewer issues overall than the EcoDiesels. I would have probably gone with or switched to a Touareg had I not wanted air suspension and Apple CarPlay.

If you go with the Jeep, you basically have to do engine and transmission tunes to end up with a tolerable driving experience. So be prepared for that. I'd recommend finding a 2018, as those should come with a lot of the recalls done, including the emissions recall, they come with CarPlay/Android Auto stock and they have a few additional safety features on the higher trim levels.

If you don't care about CarPlay or the added safety features, an earlier model would be fine. Just check their VINs on the Mopar recall site to see what has and hasn't been performed.

I have a 2014 with 55k miles and have overall been very happy. I haven't experienced the same issues some have (although my mileage is probably on the lower side).

That said, my next SUV will probably not be a diesel, unless the 2021+ JGC gets the new ecodiesel and time has shown that similar issues have not arisen.

I'm looking into purchasing a new 2018 Grand Cherokee Limited EcoDiesel. Are the 2018s problematic? What should I look for on the 2018 vs. what is posted above? Should I steer clear of the diesel? I love the idea of the gas mileage, torque, and longevity typically associated with Diesel engines. Any feedback is appreciated. I've had two Cherokees but this will be my first Grand Cherokee.

2014 Jeep Grand Cherokee Summit Eco diesel.

This is by far the worst vehicle I have ever owned. 12 recalls, transmission and exhaust emissions
issues from day one. Clunky transmission re programed 3 times in the first 2 years and still slips
when driving cold. Exhaust emissions I was offered a fix that took power away from the engine when repaired, I thought I was buying a SUV from day one that was good for the environment and was lied to, turbo charger went after 2.5 years, numerous leaks, 110 000 km fuel and fuel injection system breaks, 11 000 repair, 14 months later 133 000 km Air shocks leaking $3900.00 repair bill.
There have been numerous other issues and I would be happy to email to anyone interested.
Over all I have spent over $20 000 dollars in repair costs since the warranty ran out and still only has 134 000 km on this vehicle.
I have contacted Chrysler and Jeep and they say its not their problem and your warranty has expired.
I just want a large company to stand by their product that they sell you not this garbage product.

Any feed back on what I can do would be appreciated as well.

to the gentleman prior to me...brohiem you need to hurry TF up and get your hands wrapped around the Alcantara/Nappa Leather steering wheel of a High Altitude Turbo EcoDiesel Grand Cherokee.
I'm coming up on 6yrs with my 16' High Altitude Ecodiesel and I just hit 56k miles. I paid $60k total, if you add up the payments on the principle as well as the interest over 60months. The Green Diesel Engineering Hot Tune ($675) matted to the re mapped amazing Trans Tune ($500) with a pedal commander also. It's got about 300hp at the wheels and 540lbft. The GDE ECM engine Hot Tune I had installed within the first 90 days of buying the Jeep. It wasn't until roughly a year or so, 2018 is when I added the Trans Tune on to top of the Hot Tune. That hour driving from Commerce Township back home to Detroit with both Tunes cranking and working together at the same time felt the best that engine has ever felt!!

I have a 2015, all in all ive been happy, there have only been two recalls one is the infamous flash tune for emissions, no thanks, And now an EGR diesel cooler that has yet to be addressed. I bought it specifically to tow my smallish travel trailer and thus far it has done that well here in the moutains of Alaska. But... as of late the oil temp is running hot, especially during towing, maybe it has to do with the recall? Im sure its fixable though so all in all not a huge deal, i'm working through it. Frankly what else is out there thats comparable? I don't want, need, nor can I afford some big diesel truck, I don't want a gas motor to tow with so I guess i'm here for the long haul after all its paid for now.
Ive got 88K on it and never had a repair done, im a stickler on oil and fuel filter changes and the scheduled maintenance. I did find something recently that amused me, this motor was developed for GM not Fiat or Chrysler when GM had an ownership stake in VM Motori the builder of the engine.
