Re: Rear bump feel when accelerating

I have felt this as well, but I don't have load leveling suspension. Its just a slight bump, to me it feels like rear tires slipping on the white crosswalk paint at a stop light.

Re: Rear bump feel when accelerating

Set to take a drive with the service manager on Saturday. The guy I'm dealing with is pretty good, he does all our company vehicles. He said the only thing he saw was the TSB pointed out by Milous, but he said it could simply be a flash of all the computers, maybe the trans and transfer case and ECM aren't talking nicely together with the traction control/ABS. We'll see

Re: Rear bump feel when accelerating

Went for a drive and...the service manager said, "you are right, something is definitely wrong there, that isn't normal". He said he'll have to do some research(see if jeep is working on a fix or knows about it and hasn't published it yet), he's going to talk to the regional service advisor or something like that, and see what he can find. He said he personally feels like its in the t-case or tranny, and definitely driveline, and if necessary he will have the master, regional, technical, big title yada yada come for a ride with me. He was cool, understanding, and said they will work to get a fix because its not right, and its a new car with 8k miles on it, and shouldn't do it...period.
Possible culprits...t case, tranny, driveshaft (more likely)or software needs a flash to make the t case, tranny, abs, tcs, etc all talk nicely(not so much), and will look into the self leveling shocks TSB. Ultimately, I have to just sit and wait. Will update as things develop.

Re: Rear bump feel when accelerating

I believe I am experiencing the same bump as this thread is describing, I've attached a video in a thread I started yesterday...can anyone confirm if this is what everyone else is hearing?

nope, not the same bump. Your bump is felt while decelerating (letting off the gas), this thread is related to a bump during acceleration. Kind of like a bowling ball rolling around in the cargo area when you hit the gas from standstill.

Re: Rear bump feel when accelerating

Wow, I just saw this. The TSB 21-003-13 / 21-004-13 may solve both the "bowling ball in the trunk" bump during acceleration and the sand issue! It would make a huge difference to me if I got those problems solved, like going from "Chrysler does NOT stand behind their products" to "They actually solved my GC's problems". I definitely have to have this update even though I have long given up on the Jeep dealers.

Of course there are plenty of other issues, like the side mirrors folding at engine start (which is resolved by a TSB 08-011-13 for Japan only even though the Australian models have the same fault) and recently I have had problems with the aircon not being able to switch off (lamp goes off but aircon stays on) and about 20 other "abnormalities". I guess it's not easy to fix all these things but the dealers attitude of "we don't see any fault so you must be wrong" is really annoying. Even when they acknowledge a fault they so far haven't wanted to do anything except try to explain it away.

Well, sorry for the rant but I am really close to giving up on this vehicle due to what I consider extremely poor service from the dealers. Maybe, if they will give me this update, there is still hope?

Re: Rear bump feel when accelerating

So, I spoke to the shop manager yesterday. He said, I didn't forget you, your info is taped to my keyboard. He said he's been driving one of the owners demo(hemi, etc so apples to apples) and he drove the exact route I took him on, and while he said he can get it to do it, it's very slight, and he had to try and make it thump. He said, your jeep the first time, I was like, whoa, that's not right.
He spoke with the regional service manager guy, who has been driving different grands in the region with about the same miles, etc, and said most all of them do it...A LITTLE. My local guy told him, no, this is very abnormal, very noticable, and it does it even trying to drive easy. He told the regional guy, I really feel it's T-case or tranny or some combo. The regional guy said he spoke to the Jeep engineers, who are also looking into it, and mentioned I might be causing damage from driving it! I said, well, it's under warranty, Jeep can put a new one in for me if that's the case, or give my wife a '14 Grand, no Dart/mini van/journey, a '14 Grand Limited like my '13 to drive, and put mine in the shop. I said, he can come down, and we'll go for a ride too, and I think that's gonna happen.
Now, here it gets a little interesting. He said the regional guy/engineers said they can go in to the computer, and "lock in" the 4wd, not low range, but like "Command Trac" in the Wrangler, where it would "buck" if you were on dry pavement, like most of the part time systems. But they aren't sure if they can drive it in that mode, but it may somehow be in that mode, or they may try to put it in that mode and drive it, then take it out, flash the computers, and if it still does it...punt I guess.
I said, this is our 10th jeep vehicle, 4th Grand, and our '93 and '96 have over 450k miles between them, and while rough, still run. I said, we picked this over the X5, ML350, Q7, because the wife liked it best, and being a better value was a plus. I would hate to have to go buy one of those, especially because in a year ish, I want a diesel/8spd. He said he'll pass that message along as well. I also said it seems to be getting worse too, so a little fire under the ass would be nice too on Jeep's end of it. Sooo, we'll see, but my patience grows thin.

Unhappy Re: Rear bump feel when accelerating

My 2012 JGC has the driveline bump from stop upon accelerating when making left turns and straight ahead about 10 mph - almost consistently. I was so disappointed today when the Jeep service dept told me this TSB did not apply to my 2012 WK2 5.7L Hemi Jeep Grand Cherokee with Quadra-Trac II 4WD and the 230MM Rear Axel with Electronic Limited Slip. I showed them the 21-003-13 TSB, but it was not listed under my VIN on Chrysler DealerConnect, therefore they won't apply it. I had them list my purchsed vehicle options, but I could not find sales code DR1 or DSF. It did list a Quadra-Trak II (R) sales code of DKAS.

Anybody else get turned down?

I suspect either the TSB is written with the wrong sales codes or this TSB is too new and hasn't yet been entered into their Chrysler DealerConnect system yet. Any insight here?
Thanks, Rich....

Re: Rear bump feel when accelerating

It's looking like Chrysler/Jeep may not have properly entered the TSB affected vehicles into their database. I obtained my Vehicle build sheet with sales codes. I have:
DKAS Quadra-Trac II (R) 4WD System
DR1P 230MM Rear Axel
DSFP Elec LTD Slip Differential Rr Axle

These sales codes match the TSB requirements, except that they each have 4 characters instead of the 3 listed in the TSB:
DKAS vs. DKA
DR1P vs. DR1
DSFP vs. DSF

Hopefully this TSB get's striaghtened out. Stand by....
