QuadraLift problem

In Normal ride height I have no problems. When I raise it to off road 1 that's where the problem begins. If I hit a speed bump in OR 1 I hear a loud bang. It's even worse in OR 2. Is seems to be when the bags are "rebounding" from the compression of the bump. Any suggestions as to what the problem may be? I understand that in those higher modes it will ride stiffer but it almost seems like it's bottoming out and it's an extremely loud bang.

Re: QuadraLift problem

It's typical. Most people who complain about it are driving in a raised position on the road, not off road. It happens because the higher the car is raised the less room it has to move going up.

Re: QuadraLift problem

its not a problem its just a shit design and a great sales gimmick. in any other 4x4 with coils you still have suspension as such. with airbags the tighter they become they dont compress as easy and acrually ride stiffer. thats why in sport mode or over 60mph the ride is plush the air is let out of the bags and absorbs all bumps.

Re: QuadraLift problem

I understand the stiffness. But this actually sounds like you are taking a sledge hammer to the differential.

Re: QuadraLift problem

Normal, tons of threads about it. Slow down or lower the vehicle or live with the noise. Sucks.

It's not a "problem"...as already noted, it's the nature of the suspension design. When you raise it up, you have very little travel left, especially at OR2 height. That's why it's limited in speed and will drop down when you exceed those limits to the next lower setting until you're back to "Normal". OR2 should only be used when you truly need that extra inch or so. OR1 is fine for many off-road situations and at off-road appropriate speeds. It wasn't designed for "street driving". Normal and Sport are setup for that.

Re: QuadraLift problem

As stated it is considered "normal ". I did the same thing you did. So excited to have my brand new fancy 4x4, on the way home from the dealership I raised it up, on my street and went over our speed bumps going less than 5 miles an hour. What the hell was that noise? Did they forget to install the shocks?
Called the dealer they had never heard of such a thing. Took it in and the service advisors jaw dropped when I took him for a ride. I then took their suspension guy for a ride. He said "yeah, that's the air shocks, they do that."
In a Chrysler survey I said that my concern wasn't handled. They wanted me to take it back but it would cost me $50.00 for diagnosing the issue if it wasn't considered warranty.
I gave up. Those who are telling us that it isn't an issue because it isn't supposed to be used when going over speed bumps and is only for off-road use clearly don't know that it is unacceptable at any time.
I've since taken it off road in fairly mild conditions. It clunks unbelievably.
I am extremely disappointed. I'm stuck with the jeep. It is very nice with the exception of the suspension design.
There is a comparison of the GC, Range Rover, Chevy Siverado and Ram 2500 in Off-road Magazines 4x4 of the year.(2014) They site the suspension problem as one of the cons for the jeep. They suggest that the Range Rover used to have the same problem but they figured out how to fix it and Jeep probably would too, in the future.
I wish I had read this review before I plunked down 45k for my first Jeep. My old dodge and my old Landcruiser sure don't clunk like my new fancy 4x4.
Hopefully Jeep will get the hint and come up with a fix.

Re: QuadraLift problem

ORII is designed for extreme conditions where you have to crawl over something. Most people, even those who go 'off roading' probably never need it. If you do need to use ORII, 5mph is probably too fast.

It is not designed for speed bumps at the mall.
