2014 GC and a newbie

Im a life time GM/Ford owner looking at purchasing my first Grand Cherokee / Chrysler product. The 2014 GC 3.6L overland offers everything Im looking for, capable towing, luxury interior, decent gas mileage all in a size that's manageable around town. Excellent! Having said that I am somewhat concerned about the reports I am hearing about the lerching/rough shifting trans in the 3.6L. Im looking for honest feedback from the forum on just how widespread and "serious" the problem is. I took one for a test drive and obviously being it was new I experienced no such issue. For those of you that have one, is the issue enough that you regret your purchase? With enough patience (and enough time at the dealership) are you able to get a resolution? It appears the issue isnt as widespread with V8/diesel motors but those doesnt appeal to me. Any and all input is appreciated.

Thanks!

Re: 2014 GC and a newbie

There's been a considerable amount of discussion on this subject in here.

I have the 3.6L and I've never had an issue with rough shifting before or after the TSB flash. It's probably the smoothest shifting transmission I've ever owned.

Granted, it sounds like the lighter duty 8-speed used with the 3.6L is more susceptible to this type of problem than the heavy duty 8-speed used with the V8 and diesel. The transmission software algorithms are different.

Since these are both "learning" transmissions I often wonder about the driving habits of those who have been the most vocal about the problem. No offense to anyone, but if they like to get on and off the gas aren't they responsible for what the transmission is learning from their driving habits?

That's not to say that some more conservative drivers haven't been experiencing the same thing, which makes it a legit problem.

Re: 2014 GC and a newbie

I suggest you drive the one you want SEVERAL times before you take the plunge. I've had several SUVs - chevy, ford, jeep, toyota, back to chevy and now back to jeep.

Dumb move on my part, as my jeep has serious tranny issues. Should have gone with my gut and told the wife no after our first jeep 7 years ago had lemon law declared on it.

I feel I may be batting 0-2 soon...

Re: 2014 GC and a newbie

I have 1700 miles on my 3.6L and the only issue I've had was the CV boot clamps came loose on both front sides, new axle half shafts were overnighted to the dealer and fixed the next day. I have zero issues with the transmission and don't regret trading my truck for the Jeep. I think a lot of the earlier 2014 builds had these issues, but slowly they have been working out the kinks. I will say that the around town gas mileage of the 3.6L doesn't really impress me, but on the highway is where it really shines.

Re: 2014 GC and a newbie

For what it's worth, I have the 3.6L. 2014 4x2 Laredo. Have only done about 1500 kms. Have driven it in Eco mode, Eco off, and sport mode. The 8 speed auto behaves differently in each of the 3 modes which is expected. It is a very smooth auto In all 3 modes and I have had no issues at all but get that the car is still very new. Eco off is the best mode for me. Great auto, but seems that a minority of them have issues.

Re: 2014 GC and a newbie

Funny you say you had no shifting issues, since mine has the problem, I went into the dealer and drove a few of them... both had the same problem. The first 2 shifts will be much harder (and lurchy) than the rest. Just be sure if you get one... to drive it from cold. and really give it a range of throttle starts. Slow accel, hard accel, med, etc... note the shift from 1st to 2nd and 2nd to 3rd... if its shifts smoothly... you found a good one. BUT... that doesnt mean it wont be plagued with other problem. I can honestly say I No longer would ever recommend a jeep. Especially the 2014. worst New vehicle I have ever owned.

Re: 2014 GC and a newbie

The potential exists for problems on any vehicle... no one builds a perfect one.

The same applies to an individual's tolerance for them.

Re: 2014 GC and a newbie

I have been very happy with my build which is a 14' Altitude. The build date is 3/15 and there has been no CV Boot problems nor rough transmission shifting. Let me rephrase that, there are no transmission shifting issues after the first week. What I found was that the transmission, being new, had no idea of my driving methods. As mentioned above the 8-speed trans is a "learning" transmission and I expected some roughness when picking up my Altitude with only 7 miles on it (and reading this forum prior to making my purchase decision). There was no way to tell it how I drove before delivery.

The first few days it was clunky when downshifting and slow to respond when giving it gas. Don't get me wrong, it wasn't "holy crap this is terrible" but rather I came into it knowing there might be some up front roughness. After the first week of driving (approximately 600+ miles), the roughness and clunks went away. Now, after 3 months of ownership and 5K miles, the transmission shifts smoothly like butter.

Of course I was nervous but I did my research of the transmission problems and also how the trans functions before pulling the trigger. Remember, the JGC is popular with approximately 180,000 sales since MY 14 release of last year. If the major issues persisted throughout the majority of the units, the JGC sales wouldn't be growing as they are now.

Welcome to JEEP! Enjoy it! Have fun in it! Make sure you post pics after you get it.

Re: 2014 GC and a newbie

So the consensus I am hearing is that the trans issue depends somewhat on a person's driving style? Easy on the gas with lots of highway speeds and its a non-issue? More "aggressive" drivers are more likely to experience the problem? My current vehicle is a Cadillac CTS and I would say I'm somewhat more of a spirited driver, add to that I live/work in Minneapolis so I do have a fair amount of stop and go commuting in the evening. The Jeep dealers here all offer a lifetime powertrain warranty with every new GC but based on some of the responses here it appears some dealers like to play dumb or arent exactly going out of their way to make it right for some of you. Anyone here in the Minneapolis area recommend a dealership with a good service dept that really stands behind what they sell?

Can I ask was yours a recent or earlier build GC? It seems based on your other posts you indeed have had your fare share of issues with yours.

Re: 2014 GC and a newbie

early build... I picked mine up 7/19/2013 and I know it was well before that because of the radio s/w version. Yes I have had waaay to many for my tastes (esp for 7k miles). my 2011 was very early too.. like early oct 2010.. zero issues

I have had no problems with Park Jeep in Burnsville. I have slight shifting problems and waiting till I get back from vacation to take in for brake recall and to do latest TSB for transmission.
