#192 of 198 2012 GC overland vibration & noise problems
Jan 24, 2012 (12:42 pm)
I just purchased a 2012 GC Overland with the V6 engine. Between speeds of 50 to 70 mph there is a floor vibration that is very noticeable. This also results in a noise problem .At 75 mph the vibration goes away and it is a great ride. The dealer agrees that this is a problem and that Chrysler is aware of it, but presently does not have a fix. It seems like this problem is only on the Overland model with the air lift suspension. They also told me I could not file under the lemon law for it would talk three attempts to fix and they would not even attempt to fix it because they do not have a cure for the problem . I also noticed that they are no longer advertising the lift suspension any more. I assume there are others with the same problem ? I am open for advise on how to handle this

I had exactly same problem with GC Overland 2008. Jeep dealer took it apart, they even send some parts for special balancing. Then they returned car back saying they did not find anything wrong and that it is caused by switching the HEMI engine. I also got "official" leter from Chrysler that it is a normal behavior (what a bullsh*t!).
However, when they returned the car, the problem disappeared. Therefore I suspect that they know it is some kind of design flaw and they fix it secretly so they do not have to recall many cars.
Keep pushing your dealer to have main axis (I do not know the proper English word, it is the big one that goes from front wheels to rear) re-balanced.

After many repair rounds with Chrysler replacing things (like a new drive shaft) and balancing tires, the vibration in my 2008 JGC Limited (with Hemi) still did not go away, I finally invoked the Lemon Law. After a settlement with Chrysler, I took the Jeep to Discount Tire and had the tires computer ride matched - wow, what a difference. The vibration disappeared and I even kept the Jeep after the lease was up as its been reliable otherwise. Just put some Michelin tires on it and the ride is super smooth at all speeds.

jeffsr, I wanted to know what the outcome of your Overland vibration is so far. I may purchase one of these in the future, but not if there's a potential vibration problem. Should I stay away from the Quadra Lift suspension?

dont know if you got the problem fixed but it might be death wobble so check out the tie rods and the track bar(panhan bar) if the bolts are loose it can cause similar issues it seems odd but i found this to be the problem

We've had a 2012 Overland with Quadra Lift since Dec. and noticed the vibration problem soon thereafter. I thought I'd let it get worse to make the problem more noticeable for the dealer and let them feel it also. It did not get any worse but it really bugs you after a few miles at 70 to 75 MPH. We took it back to our dealer that we have a lot of faith in and they fixed one issue (unrelated) and asked us to bring the car back for two days while they looked into the vibration problem. They finally said that Chrysler knows about the problem but there is no fix but did not mention the Quadra Lift connection. There should be a lemon law resolution for this.
