Vibration in GC Overland with Hemi

Hello Folks!

I'm new to the site but have over 600K miles on Jeeps. Just recently bought a 2012 GC Overland with the hemi - I am disappointed with a vibration at acceleration and higher speeds, especially when going uphill and turning, does anyone have any suggestions? I have been working with Chrysler and they suggested higher octane gas, that did not work,any support is appreciated.

Re: Vibration in GC Overland with Hemi

I have the same issue with a 2012 Limited with Hemi. Took it to the dealer. The guy drove it (while I was in the waiting room) and said he could not duplicate the problem. Turns out he drove it on level road and then on a very steep hill. Neither would duplicate the problem. It happens consistently on slight upgrades with part throttle. Hoping for a TSB fix.

Re: Vibration in GC Overland with Hemi

I have the exact same problem and I have the same Jeep. Have not heard of any solutions as of yet but higher octane gas does not help, been there done that.

Re: Vibration in GC Overland with Hemi

You may want to check out threads where shudder is discussed. I sometime get a shudder on steeper inclines, but I think the revs are allowed to go too low and the transmission clutches shudder a bit searching for the right gear. Give it a little throttle and the shudder disappears.

Vibration on turns can be a tire problem, what pressure are you running? My tires vibrate when on the lower part of the range, smooth when inflated to higher pressure.

Do you have 20 inch wheels?
