Hi everyone! Looking at getting into a Grand Cherokee with the ecodiesel. I like the idea of a midsize suv with decent fuel economy and the ability to tow a boat if the time comes. Most use will be commuting to work.

My question is how reliable are they? I’ve been trying to get a feel for how people like them and have seen both ways. Horrible experience with emissions equipment. Or nearly 30mpg if driven carefully.

Is getting a Jeep certified a good way to go for an insurance blanket on a vehicle that is probably expensive to fix?

Should I just get the gas v6?

Thanks!

I've got a 2014 that I bought new, so it's pushing 5 years now, and I have a little over 50,000 miles on it. For the most part, it's been great. The highway fuel economy is fantastic.

My vehicle has not been without issues however. All 2014s were recalled to replace the catalytic converter (mine failed with the symptoms that triggered the recall - a check engine light, but no real change in behavior.) I have had other repairs done (the passenger side blend door in the HVAC broke a gear and had to be repaired, the rack and pinion was replaced due to leaking power steering fluid, and the front wheel bearings were replaced not long after I got the vehicle - all of this under the warranty and extended warranty I bought).

All that being said, aside from the catalytic converter which was recalled, I've had no issues with the vehicle due to the diesel engine or its fancy emissions system. Other people on this forum won't have that same experience however, and you'll hear more from people who had issues than those who haven't.

If you are buying used, I would inquire about the status of the class action lawsuit and how it impacts your purchase. For folks like me who have had their vehicles all along, we're getting an extended warranty for 10 years/120,000 miles total on almost everything related to the emissions system. You'll want to ask the dealership about that before you buy. I would assume it applies once the required software fix is installed on the vehicle, but you definitely should find that out.

Good luck! Any time I've thought about trading the Jeep in for something else, I drive it and then fall in love with it again.

I have a 2015 and really enjoy it. She's up to 73,000 miles and has had few issues. The previous owner did have an issue with the catilatic converter that was covered under warranty. I had a loss of power once when I went to pull my GF boat only to figure out the fuel filters were way past due for a change. Same with ther air filter. Once replaced all was good.
Highway mileage is great...25+ mpg on the highway, around 20-22 around town. Actually got 14mpg pulling a 6500lb boat 4hrs one way... mostly highway cruising at 65-70.

Good luck!

I just traded my 2015 GC diesel in to a non-FCA dealer for another car. The past 12 months has been a disaster for the Jeep. It had 77K miles on it, and spent 12 weeks in service last summer. It had failed on the road and was towed in, and the magnets on the crankshaft position sensor (tone bell?) had fallen apart. Once that was repaired (3 weeks) they called me to tell me it needed 'contaminated fuel system' repair, which was essentially a complete new fuel delivery system from the pipe out of tank to the injection system, pump, injectors and all. This costed $9K and the dealership said dirt in the system is not covered under warranty. I filed a claim with my auto insurance, and they took another 4 weeks to finally deal with it, and they paid for all but the deductable. I had the new emission fix flashed into the code, and drove it for about a month when check engine light started coming on. OBD2 said it was NOx sensor failure. With the extended warranty after flashing the emissions control changes,dealership replaced the sensor. As I drove it home, it came on again. Next month in shop again, they said must have been a bad sensor. Replaced again. This time as I drove home (20 miles) the light came on with the NOx again, but in addition I got the dreaded DEF system service message, that has a countdown of 160 miles until will not restart. Back into the dealership it went. Replaced NOx sensor again I believe (i lost count of these) and both messages came back within days. This time I decided to look myself and disconnected the DEF injector (easy to get to) and found crystals of DEF all fouled there. I cleaned it with a cup of hot water and a toothbrush, reinstalled and did a forced regen. Message came back after a day. Back to the dealership it went, as the nearest alternative shop is 70 miles away. This time they kept it two weeks, got a STAR case started with FCA service, and did a reconfiguration of firmware, yes, thats what it said. As I drove home the lights came back, but the DEF message cleared after two 10 mile jaunts. With only the nagging NOx sensor message in the OBD2, I realized it would never be fixed, they had no idea what to do. The COVID19 hit, and while sitting around at home, i decided this was enough, time to sell it. I got a decent trade, mid range. This car certainly did not live up to expectations in reliability. It pulled fine, and got 24 MPG, so that part was fine. I made the deal a day before our state closed auto sales for a while, and got a non diesel car, first time I haven't owned a diesel since 1975 Rabbit, and a series of VWs culminating in this Ecodiesel 3.0.

Well, I figured I may as well update this thread. I traded the 2014 EcoDiesel for a 2020 with the gas V8 Hemi engine. Too many issues with the diesel emission system to deal with. Love the vehicle and so far, the new one has been great. But never again will I own a diesel, and I had also had several VW diesels prior to the Jeep.

 

[FinnishWeller]

I would run away.

My Jeep dealer has had mine (2014)for over a couple of months in total over the last year or maybe even less. Engine problems, transmission problems, overheating problems, and emissions testing problems have plagued it.

But when it works, it sure is nice. Ha ha.

 

[AKcharger]

we've had our 2014 7 months now, has 99K on it and recently did the new AEM, it's fine...we're happy

 

[hernanno]

I'm looking at a 2014 summit diesel. For around $20k with 85k miles. Looks like it's eligible for the class action check of $3k. Is there anything different on the drivetrain from a gas grand Cherokee?
Any other opinions on reliability?

Wow...I think I may have purchased this Jeep...2nd day after I drove it off the light, check engine light came on, back to the dealer it went, and was there for 2wks, they brought it back to me all "fixed" NOx sensor replaced, the very next day, light back on, back to the dealer I went, 2nd day there they are telling me that its the NOx sensor again. I have drove this Jeep a total of 3 times since purchasing it on June 15 :-(

 

[jtml]

Was it a New Mexico dealer, a Jeep dealer or just a used car sale from another dealership?

Delete the emission system, all of the "problems" go away. 90k and going strong.

we're still happy

Hello, also looking at one for my family. Looking at '14-'19 Ecodiesel models. Anyone else have experience with these, good or bad?

we're still happy...took it in 2 weeks ago for another recall type flash but we never had problems and actually noticed a 1 MPH uptick in gas milage

I bought a certified used 2014 Jeep Grand Cherokee Diesel and sold it after two years of ownership for $14,000 less than I paid for it (because I didn't lie to the next victim about what a complete disaster it had been for me). In those two years it was in the shop for two to three months. Aside from the emissions problems, transmission problems, overheating, and suddenly surging forward after not taking off, it was great. One of the techs working on it told me that "Chrysler __ the bed on the these" and that I should dump it. I gave up. All that said, I've never had a vehicle I liked better when it was working.

Well it has been 12 months more have now, since you have owned your Eco Diesel 2014 have you had any trouble? I would be surprised if you have not had trouble, yet. I own a 2014 Eco Diesel V6 and loved it at first then it went into the shop for the Fly Wheel Timing under the extended warranty 3 years ago. Then I went for a year or so and brought it in for a recall update on it. Then I had a good streak of about 18 months of no trouble and the fuel system plugged, because I had after market fuel filters made by a major manufacturer and they started falling apart. The fuel system is super high pressure and you have to use original manufacturer recommended fuel filters. Anyways then I have had engine trouble to be continued in another post. Currently my Jeep is down at the dealer waiting for an inspector and claims adjustor to make a decision by the warranty company. I will post the final out come and what happened on another post soon. The short story is these Jeep Eco Diesel V6 have great gas mileage when they are running, but are terrible for going in/out of the repair shops..... To be continued.......

We have a 2014 summit we bought in 2016 I believe. It's had a few problems. Steering rack was replaced (24k miles). Transmission replaced (36k miles), intake manifold replaced at (50k miles). EGR leaked coolant that was fixed under a recall. Then the EGR replaced just today under recall.

Its been EGR deleted since around 33k miles. The intake manifold flipped an error of stuck swirl valve around 50k miles. No EGR was getting into the intake any longer so I'm going to guess the swirl valve position sensor went bad. The dealer replaced the entire thing as one unit.

Besides those issues its been fairly reliable. Transmission was replaced but it actually functioned fine. When we came to a stop it always felt like we were getting rear ended. They reprogrammed the transmission a couple times and then just decided to replace it. We used to get 30MPG on the highway but after the AEM it dropped down tp 26-27mpg highway. Tows our boat just fine. We had a Range Rover before this vehicle and will likely go back to rover when it's time to sell this one.

Hi PNW! nope still good...well, had that EPR recall and we did update to the Uconnect system to get WiFI working. I told my wife I want to dump it as soon as the extended warrenty is up but she loves it and with new and used car prices so high I'll hold on to it for the forseeable future. Oh! added a trailer hitch (yes and paid $80 to "flash" the harness)

 

[xokia]

You could look at it another way. Might be an excellent time to sell if you are not happy.
