I noticed lately on my 12 limited I get a resonating vibration at exactly 2000 rpm when going about 60 mph. I feel it in the gas pedal and the floor of the jeep. Anyone else experience this with their v6? It's like a pulsating vibration... Thanks
Mine only ocurrs during ligh acceleration. Found that I can get it to stop is I manually change it to a lower gear or take my foot off the accerator all together.
I have the same thing. Under load/acceleration going up a grade. It down shifts and it is pulsating rhythmic type vibration. Mine is worst about 2,300-2,500 rpm. Feels like a motor mount issue as it is directly related to engine load and rpm. I have an 11 with 18" Michelin's. Very annoying on a $37k vehicle.
We have a 2012 JGC Overland V6 4wd, we noticed a whineing or slight hum
when acclerating at hwy speeds (60+mph). We took our JGC in, a tech went for a drive w/ me, he heard the noise then did some reseach. He informed me that they would needed to replace the front drive shaft. When the part came in the dealership swapped out the front drive shaft, the noise does not seem to exist any more.
I have definitely experienced the rhythmic hum/vibration. As discussed on previous posts it only seems to happen on uphill grades doing highway speeds around 60 mph. I have a '12 Laredo 3.6 w/ 18" wheels and 4500 miles. If anyone gets additional info, I would be happy to hear about it.
I am still getting the noise/vibration when going up hills at around 55. I was hoping some more people had got some better answers/solutions. I may let the dealership look at it in a couple of weeks when I get some time off but I really don't think that they will be able to figure it out and just throw parts at it. Its not a huge deal if it is something that don't hurt the engine and most people in the vehicle don't even notice it but I sure do. It definitely is not the wheel/tire combo becuase most who have mentioned it on here have the Limited or Overland and I've got the Laredo (4wd) with 17 inch rims and have the vibration problem.
I have the overland.. first 3,000 miles.. no vibrations.. 'perfect'. then I rotated the tires front to back.. and I felt wheel vibration 60-70.. shook the steering wheel pretty good I could see my hand shake.. at 6,000 miles I'm like I'm going to swap it back anyway.. back to front etc.. oddly, the wheel vibration is gone.. possible it needed to round a little? (or wear some) It's fine now and just as I'm about to rotate them back. - only other thing I did different was remove the wheel locks from jeep- The new car vanity is over.. and it they steal em.. who cares... I'm trading for a CRD 2014! (btw- removing the locks didnt stop the vibration, seems it wore itself in..)
FYI I'm wicked detailed, and I use a tire depth gauge to measure almost monthly-- to ensure I don't have abnormal wear from a bad toe or alignment.
Mine went to the garage last week after I took the mechanic to a ride on the highway to hear the sound. It was really hard to bring that sound out when he was with me - Murphys law!!!
Anyway he liftet the car and checked for some loose parts without success, he was accelerating the car to around 60mph while on the lift but the sound could not be heard. This is interesting since this probably means this is some combination of speed, acceleration, road maybe also friction of tires that could not be imitated on the lift!.
Paid 50 USD for the inspection and got my car back without a clue.

It is not normal and that is the dealers way of saying "I can't fix your vehicle or I don't really care, just make sure you keep bringing it in for more oil changes".
Well my dealer said "we hear it, but can't figure out what it is. You have lots of time on your powertrain warranty so just drive it for a while and see if it gets worse or we'll see if Jeep issues some sort of TSB."
On another forum I read a post that stated "FYI, there is a very recent TSB (issued February 24 I think) about drone noises at high speeds; the TSB tells the dealer to put the vehicle in some sort of mode (done by hooking it up to their computer) which basically let's you drive the vehicle while the four wheel drive is disabled. If the noise goes away while in this safety mode, the TSB tells the dealer to REPLACE the front prop shaft. Unfortunately, this TSB did not fix my vehicle's drone (it still made noise in safety mode)."
I can not find the aboves tsb. Someone earlier in this post said a front drive shaft fixed their problem. Can anybody confirm this tsb or that a front drive shat actually fixed theirs?
Mine is at the dealership right now for the 2nd time for this concern. Last time they reprogrammed the computer for a TSB that was no way related to what I told them my concern was. I have very little confidence in my dealer. I used to be a Ford certified tech and was even a service manager for 1 year. If we couldn't duplicate the customers concern we asked them to go for a ride with us. When I offered to take them for a ride in my GC the last time the service advisor literally laughed at me. My guess is a bad axle or as mentioned maybe something to do with the front drive shaft. I thought maybe a bad mount, but that seems less likely as I don't think this is a normal "characteristic" of the engine. I am hoping it is not a transmission concern. It definitely takes a combination of speed/load to make it happen. I can make mine do it by hitting 60 mph up a grade and shifting to 4th gear. Every time that scenario happens I get the vibration.
Woooom.....woooom.....woooom......woooom. Mine does it too. On an uphill grade around 60 mph with enough throttle to maintain speed. 2012 Laredo V6. Only 800 miles on it and it's done it since i got it.
jasonl:"My guess is a bad axle or as mentioned maybe something to do with the front drive shaft. I thought maybe a bad mount, but that seems less likely as I don't think this is a normal "characteristic" of the engine."
this is off topic but I had some problems with my 2010 WK and every time I took it in for something they said "it's a "characteristic" of the vehicle". I think this is Chryslers way of saying 'FU' we have your $40,000 now buzz off lol.
Ugh. I've had this as well since getting my vehicle in March. Poked around the forum on this back then and became suitably depressed. Stayed away since then hoping there was a magic fix coming from somewhere - sorry to see it's not so.
Do all WK2s with the 3.6 have this 'characteristic' issue? Or is it just a portion? Anyone have a vehicle that doesn't have this characteristic?
I'm experiencing the exact same problem
I've taken this up with Chrysler and the dealership.. This, IMO, is unacceptable quality issue which Chrysler should immediately address. I've had the JGC 12 only for a month and the car has already been in the workshop for almost a week and still this problem is not resolved...
Have posted earlier threads. Was able to replicate problem to the dealer. Also, the regional engineer was in town and he rode in it and could feel/hear the problem. Unfortunately this seems to be an issue with the v6 ck2's. I also tried the 2013 and could replicate the problem on those. I'm surprised more owners have not reported this. I test drove the V8 and it did not have the problem. For now there is no fix for the V6 and only alternative would be to go to a V8.
I consider the issue to be a normal operating characteristic. Not desirable, but normal. It's been only mildly offensive from the beginning and after 14k miles has smoothed out a bit. I'm sill liking the 25mpg on long highway trips so it's definitely something that I have no problem living with. :lol:
I've raised the issue with Chrysler. Based on my conversations with the dealership and other investigations,this is a problem with some batches of the WK2 vehicles, which means when you will be trying to sell your vehicle, you'll have to take a hit if your vehicle has this issue. Many dealerships have reported this issue and now it's Chrysler that has to fix this. I'm worried about driving a vehicle which seems to be inherently flawed. This might be a big safety issue which Chrysler is ignoring to address. In any case Chrysler has a defective product on the market and they ought to either take responsibility and fix the issue or buy take these cars back and give us cars which work.
I have a 2012 Overland V6 and in 4th gear at 2000 rpm's underload it makes the same sound...harmonic...woo..woo...woo...woo. There is no slipage with the transmission...just a harmonic noise. They put the ears on and said it was a front left wheel bearing. They changed that and it still makes the noise.
Mine does the exact same thing. Going up a hill around 60mph doesn't matter if it is 4th or 5th gear. Just now over 1000 miles on it. I thought it may of been a motor mount needing to break in or something. Sometimes I think it may be the left front axle but it is hard to tell. It is definitely noticeable. I will send a thing to Chrysler as well using the website posted in this thread. It is not acceptable to me since this is the first new vehicle I have owned. I have owned two other used Hondas and drove the until almost 200000 miles with just doing regular maintenance. My wife talked me into the Chrysler brand since her dad loves them and has not had any issues. Most of the previous years of the GC seem very reliable is why I decided to give them a shot. Hopefully Chrysler will have a fix in the near future or it may be my first and last Chrysler.
I hAve the same harmonic sound it started like yours under load and up hill I have a 2011 overland v8 the dealer changed both front wheel bearings and the noise went away for about 500 miles then slowly came back now it is at the point where you can hear it at 20 mph and over low volume levels of the radio. The noise is very load around banked turns.i have been dealing with mine since February along with a 1 month stay over the dealers. Good luck I wish some one would find a fix. I also had a allignment done by the jeep dealer and replaced tires as per Chrysler so we could find a fix.
Something else is wrong with your car. This is not the harmonic sound that most are describing. You should have a talk with your service advisor, take him for a ride and duplicate the sounds so he can diagnose it.
This noise is a V6 problem and I don't think it has anything to do with the wheel bearings but a driveline/motor issue. I have gotten used to it after 7K miles but still do not like it.
Yeah it is just frustrating. We looked at Explorers and while they are nice, I liked the looks and size of the Grand Cherokee so much better. It is my wife's daily driver or other wise it would drive me nuts just the OCD in me... We have 33k now and it is no worse or no better than when I fist noticed it at 22k just 1,000k after we bought it. here's to hoping they address the issue with a fix and not a bandaid.
