New 2011 Liberty with Vibration and Growl

I purchased a 2011 Liberty last month and have put 1000 miles on it.

Under power there is a growl and vibration. You can feel it in the floor and even through the gas pedal. 40 mph plus

If I coast about 80% of the growl noise goes away and much of the vibration stays. The vibration does not shake you, but it is a nuisance to say the least. Makes the purchase very disappointing.

I took it to the dealer service manager who drove it and he said it was normal and called it "torque converter lockup".

I am bringing it back to the dealer to get a better resolution.

Any ideas would be apprecitated.

When I had my 09 Liberty it had a growl or drone at about 50mph after torque converter locked up. I think it was really the exhaust you feel with the engine under load. It was normal because I compared to another one that did the same thing. The persons vehicle that I compared it with didn't even notice it, but I found to be annoying. I think this is something that should have been worked out by engineering instead of just saying "Its a Jeep".

there are certain trade offs that im willing to deal with in terms of sacrificing luxury for offroad prowess. vibrations and ride quality are one of them. KK is not affected by them as much as lets say JK is. unfortunately engineering is not going to work out anything for liberty anymore since 2013 is the last year for the model, and i doubt they would anyway, complains like this are pretty rare, its all in the eye of the beholder. my wife moved to the KK from MB c230 and she just loves the ride quality. so.. its all subjective

I spoke to the service manager and I am bringing the Liberty in for road force wheel balance. He will also perform drive shaft run-out and balance that if necessary.

I see these Libertys running around all over , driven by various types of drivers. Only a guess, but if 2% were using them off road I would be surprised. Off Road Capability is also marketing.

The Liberty may not be the newest technology but it was not designed and tested so that a growl and vibration would be normal as a trade off for "off-road", imo. We are not talking about a vehcicle designed and built in 1965.

My Liberty handles very well, take bumps nicely and I like it. That being said, I have one issue, this Liberty seems like it has truck snow tires on it with a tandem axle at times.

Yeah mine does not vibrate new at 2500 miles. That is not normal.

Have them fix it. It's more than likely a wheel balance/alighment or drive shaft issue, as the service manager was suggesting.

We are all under warranty until 36k miles, so your good.

Yeah, vibration isn't something you have to settle with.

Our 2008 Liberty was light-years ahead in terms of smoothness compared to my xj.

I have a 2011 Liberty and I've noticed that when I have the AC on (I live in AZ) there is a noticable vibration when idle and a vibration and growl when going at low speeds. I just figured that was normal behavior with the AC on.
