Re: Shutter/Jitter While Jeep is Cold and Stopped

Yeah, you'd think by now they'd have developed a permanent fix for these shifting issues. Results are all over the map for a lot of people and that's frustrating. So far my 16 has been fine but the question remains, will it stay that way long term?

Last night I had one incredibly rough 1 to 2 upshift after a cold soak, enough that the Jeep hestitated/jerked forward/shook. As of today I have no 2 to 1 downshift shudder (which had been occurring 95% of the time as of late). I had not disconnected the fuse or battery.

Of course, this pattern makes me suspect hardware issues rather than maladapted learning. I guess we'll see. I'll still try the flash/recall/adaptive reset recommended by MDBones, but it will probably be weeks before my dealer will fit me in.

Re: Shutter/Jitter While Jeep is Cold and Stopped

I have a 2014 ecodiesel Overland that just recently do the same thing. It hasn't been happening frequently enough to bring it to the dealer but I only have 24,000 miles on mine. I get the clunking in the transmission it seems when slowing down to come to a stop at a stop light. Not sure if is the drop in RPMs that are doing it or the drop in gear. I'm only slowing down from 20 to 30 mph to come to the stop when it happens and its seems to happen when I'm close to coming to a complete stop. Very frustrated that I can't seem to replicate it because if I can't replicate it then whats the point to taking it to the dealer.

You should at least bring it in so they can record your concern and do an update. This will at least log you in the system so when / if it does keep coming back they know it started at a certain mile on odometer.

Re: Shutter/Jitter While Jeep is Cold and Stopped

Talking with my wife, it continues to be a hit and miss condition. She did make a comment that it did it to her the other day in reverse (and when she came to a stop). So that would eliminate the downshift theory.

The wife took the Jeep in for a service. She asked them to take a look at it while it was in the shop. Of course they couldn't replicate the issue. They went ahead and did the recall flash. I guess we will continue to see how it goes.

Re: Shutter/Jitter While Jeep is Cold and Stopped

I get the same "thud" sporadically when I'm going slow in traffic. It also happened recently when slowly accelerating from a stop (still in traffic) so it's probably not a 2nd to 1st downshift problem (in this case anyways). To me, it sort of feels like something is engaging/disengaging. I'll definitely mention it the next time I bring it in for an oil change.

Own a 2014 Jeep Grand Cherokee (Overland) w/ the ecodiesel. I've had it for just over 2 years (25 months to be exact) and just under 39k miles on it. For the most part we haven't had any issues w/ our jeep. However for the past couple of days it has been acting up.

I live in Houston. Last Friday, the family made a trip up to NW New Mexico to visit Family. My wife and son are staying up there for a couple of weeks (they have the jeep). On Monday morning (after sitting overnight) we went to run an errand. Jeep started up ok and drove down the road and got to a light. While stopped at the light (just foot on the brake), the jeep started to shutter, jitter, or as my wife calls it "jiggles". Felt like something was trying to push the jeep from behind. Enough movement of the jeep that my wife (in the passenger seat) turned to me and asked what that was. Light turned green, we made it to our destination (we didn't stop again), and after that we didn't feel it again, at least for the rest of the day. I figured it was an anomaly, forgot about it, and flew back home for work. Well talking to my wife today, it sounds like the jeep has done the exact same thing for past couple of days. Every time, its been after the jeep has sat over night. After driving around for a bit, it goes away. Never had or seen anything like this before the last couple of days. Jeep has NOT had the recent warranty flashes preformed (for the shifter).

Seems how we are only seeing it after setting over night, I am thinking being cold has something to do with it. Don't know if elevation (going from sea level to 4600') has anything to do with it?

Anyone got any thoughts on how to go about trouble shooting?
I think you're talking about something completely different than all of these transmission guys. I say that because mine has done the same thing for months, namely after getting my heads replaced. It's intermittent, sometimes happens in the morning after a cold start but sometimes after sitting for 45min. Sometime not even after driving. You stop at the light and it starts to misfire and shudder, so the vehicle starts to shake and feel a bit jumpy. The part where you said you're at a stop, foot only on the brake is the key, not downshifting or any shifting.

Anyhow, I've taken mine back in numerous times, and each time they can't replicate, because it's too sporadic. I hate it because it's 2 yrs old, has 40,000km on it, and it sucks to not just want to run smoothly. I'm at a loss for what it is, I blamed the head replacement but that dealership left me high and dry as well as Chrysler canada (see my posts in the tsb discussion).

If you get it figured out, i'm interested.

Have you replaced the fuel filters? How many miles on them?
What level was your fuel tank at?
Have you tried a quality diesel fuel system cleaner?
Do you run any fuel additive?

40,000 km now, been doing it since 27,000km, fuel level never matters, only run top tier fuels, no pour in additives

Re: Shutter/Jitter While Jeep is Cold and Stopped

So I took mine in earlier this week for this issue along with a oil change. Shockingly they claim to have felt it and took out "similar vehicles" and were getting the same issue and told me that its just a characteristic of the car. i obviously don't agree because of the sporadic nature of it but I am going to wait and see what other members find out.
