Re: 2014 EcoDiesel Overland Transmission Issue

Mine was a January 2014 build. Funny you should mention that the reason for your shudder was a failed regen. I did a month ago get a check engine light for a failed regen.

I also was on the highway yesterday and was getting a constant vibrating in the steering wheel, when the check engine light came on. The dealer can't read the code until this friday.

Aside from this issue, which is a pain, i do like the vehicle. I just don't like how a lot of people have experienced this very saner issue and Jeep hasn't fixed the issue.

How was your dealer able to diagnose that the failed regen was causing the shudder? I can't get the shudder to happen when a dealer takes it out.

I wish it was a regen issue. That would be an easy fix in software.

If the shudder occurs on the first occurrence of the 5 to 6 shift under light throttle after startup and then goes away if you accelerate or downshift, it's the same issue as others are having. A new TSB update to the TCM is due soon to address this. Mine does it sparadically...I just accelerate through it quickly for now.
I came across this article about the Cherokee transmission problems and delays in production due to Jeeps efforts to resolve the issues before building any more. I wonder if perhaps Jeep is delaying production of the Grand Cherokee Diesels until they can fix the problem. It would be a great comfort to think that I won't get my 2015 Ecodiesel built until they can do it right.

Re: 2014 EcoDiesel Overland Transmission Issue

The only reason jeep has the delayed the production of the 2015 eco-diesel is because the ram eco-diesel orders have far and above exceeded the sales expectations. They oversold the truck, and only have XX amount of engines for use. it has been well documented both on here and other forums.

Well this wasn't my car, it was another owner, see the link. They took it to the service dept, they couldn't work it out, so they raised the issue with Jeep Australia, and they suggested the issue was failed regen and told them to replace the DPF and a related sensor..... fixed the problem apparently.

My car has 4,000kms on it and is going fine, but starting to notice low speed harsh gear changes in 1st and 2nd..... might need to get the TSB applied.

Hi Jason - I know, I'm well aware of the stated reason for the delay. I'm just wondering if perhaps there is more. I really hope there is more to this - if Jeep really plans on continuing production on the "same" Grand Cherokee they were building before they shut down the lines to focus on the Ram, then we don't have a lot of reason to be optimistic that the 2015's will be any better/any more trouble free than the 2014's everyone has these issues with. Why would someone who knows these issues in advance be willing to risk the nearly $50,000 to buy one? (That's my issue)

I wouldn't risk it.

Re: 2014 EcoDiesel Overland Transmission Issue

As I sit in the service department waiting on my jeep....I had a check engine light come on a week ago and I came in today to find out what was wrong. Apparently it was a o2 sensor failure. BUT....according to service guy, jeep just came out with a update dated today for Jeep Grand Cherokee Eco-Diesel that has 30 or 40 some odd fixes. Just FYI...

I highly doubt this will fix my shudder, but who knows

Re: 2014 EcoDiesel Overland Transmission Issue

My check engine light also came on about a week ago. The code is for NOx sensor failure. I think this is different than the O2 sensor but would be interested if the latest update cured it.

Is it the dreaded P20EE code? That indicates a bad Catalytic Converter.

'14 was a major refresh for the Grand Cherokee. The EcoDiesel was brand new to Jeep, the transmissions were brand new, the Uconnect system was substantially upgraded... you get the idea. Additionally, production started on '14 Grand Cherokees WAY early in 2013. Demand was high, and perhaps they wanted to strike while the iron was hot.

It seems to me (at least) that Jeep started building the new Grands before all of the kinks were worked out. In doing so, they should have at least tightened up their quality control. Unfortunately, that didn't seem the case. In fact, there was substantial anecdotal evidence here on the forum that the quality control was lacking - particularly early on in the production run.

Any time there's a refresh or re-design, the first model year cars will have a higher rate of "issues." Manufacturers implement rolling changes between model years - and in many cases DURING a model year - to address the issues. In many cases, they will implement the cheapest and most simple fix they can come up with (e.g. zip ties instead of a skid plate to address the DEF injector/harness vulnerability).

Consequently, in exchange for the cool factor of being the first one in the neighborhood to own the "it" new car, early adopters wind up being beta testers, of sorts.

The way I see it, '14 owners took a gamble by buying the first model year. Meanwhile, I'm confident that my '15 will be more reliable and have less bugs that an early build '14.

I've been the early adopter before. My first Pontiac Solstice was an early build '06 (the first model year). While I didn't experience any of the major issues (leaking pinion seals leading to self-destructing differentials was a common problem, for instance), I DID sell it four months after I took delivery because I found out the Air Force was moving me overseas. I called GM's warranty department, and was told my warranty would be no good in Europe. Too much risk for me. While I had it, though, I did some exploratory surgery here and there - because I was the type of kid that took apart all of my new toys on Christmas Day and still haven't grown out of it. There were obvious assembly line "MacGuyver" fixes all over that car. Trim clips were cut from panels and re-glued in the appropriate places. Bracing for the front bumper that looked to be inconsequential was hastily cut out/modified. When I returned from overseas, I picked up an '08 Solstice (which I still own). While this one is a GXP / turbo, it is essentially the "same" car. But it's built better than my '06 was.

Sorry for the long-winded post. The point I'm trying to make is: hang in there, '15 WILL be better than '14. If nothing else, it's in Jeep's best interest to fix these issues before the build so they don't tank their reputation or bottom line with all of the warranty repairs after the sale.

Hi Muzhik - I suspect you are right. I'm just a bit nervous about making a major purchase while knowing that others have been having troubles with this car. It's crazy - the Grand Cherokee has the best combination of features that I want, but if Jeep can't rectify the transmission and diesel issues none of the other features matter.

On a positive note - I think it's going to be a few more months before they begin production and it seems they are delaying until they work out the bugs, just as you suggest. Another post mentioned that a new scr catalyst is in the works as of Dec 1st and his vehicle is in the shop until then - Jeep won't repair his car with the old model. I'm only just learning about the Ecodiesel from this forum but it seems this new scr may fix some problems a lot of folks have been having. Those of us waiting in line have the luxury of watching to see what happens without having any real skin in the game yet.

Thanks!
