Qudra lift air suspension...?

Hi all,,
As I know and read past posts on this,, id like some new feed back and recent owners input

I'm ready to make the grab on a 15 overland... And was a lil worried about this feature... I like the idea of just leaving it in lowest setting.. Unless I get some serious snow this winter... Should I be concerned.? Those that have it.. Do u really like it or is it a feature that could be done without..

Also.. Can I just leave it in the lowest setting.? Or is it always adjusting on its own?

Thanks

Re: Qudra lift air suspension...?

Whether Quadra Lift is acceptable for you depends on your ownership goals and risk tolerance. QL is obviously something that would be expensive to fix outside of warranty or extended service contract.

As for your question about settings:
  • You can't leave it in the lowest mode (which would be "entry/exit" mode), because it will automatically raise after you exceed parking lot speeds.
  • You can't really control whether it is in the next lowest mode (which is "aero"), unless you are willing to keep the transmission in "Sport" mode constantly. Even if you do, I'm fairly certain QL will adjust back to "normal" (or "entry/exit") when you turn the vehicle off/restart it.
  • You can't keep QL in "normal" mode above a certain speed, because it will automatically transition to "aero" mode. If you are below that speed, you cannot force QL to enter "aero" mode with the QL controls (the only way to accomplish this is to switch to "Sport" mode on the transmission). If you're above that speed, you cannot force it to enter "normal" mode.
I haven't found anything to suggest that QL helps to keep the vehicle level on cornering, but it seems like something that could be possible. Perhaps others can comment.

Early on (particularly on '11 and '12 models) there seemed to be a lot of issues with seals in the system. It's been quite some time since I've seen a new post about a QL issue, though. I specifically ordered ORA II on my Limited so I could GET QL.

Re: Qudra lift air suspension...?

As has been stated, you really don't get to pick what mode you-re in during normal driving. Not knowing your plans for the Jeep, I'll give you something else to consider. If you ever plan to lift or lower the Jeep with an Eibach, RRO, OME, etc. kit, you can't do that with the QL. The Limited can be spec'd out to be close to the Overland and retain the coil suspension.

Re: Qudra lift air suspension...?

My QL has been flawless to-date and I really like the feature. Yes, there have been folks with issues, but given the number of JGCs built with QL, even with an elevated incidence of problems over other things, the number of problem vehicles isn't likely very large. That said, this is one component that cemented my decision to purchase the Mopar MaxCare Lifetime Service Contract...QL, computers, other tech...piece of mind.

Re: Qudra lift air suspension...?

I was actually going to get a limited... But there are zero in my area with a hemi... And I can't wait 8 weeks for one to be built...
This overland was on his lot and gave me an amazing deal on it... The only thing bugging me is the quadra lift..

The air suspension is always adjusting on its own. You can't just set it and forget it, hoping that it will never adjust. Once you hit highway speeds, it will go into Aero mode, and then return to normal ride height after you slow down (a simple mod can disable this feature), but even if you never go on the highway, the air suspension will adjust anyway based upon the ride height sensors.

I haven't had any problems with the air suspension on my 15 Overland yet (and I would hope not on a brand new vehicle), but if I had to do it over again, I would've avoided getting the air suspension. I simply didn't realize just how often it is active and I'd rather have a fixed coil spring suspension instead. In all honesty, there's simply no way I'm keeping my Overland beyond the 3-year warranty, so it's not really a big deal for me. But for someone who wants to keep the vehicle beyond the warranty period, I'd suggest avoiding the air suspension entirely, unless of course you have deep pockets and don't mind spending a lot of money to fix it when it fails.

For normal driving you just get in and go. Aero mode drops the Jeep a half inch when cruising. You can lower the car when parked to make it easier to get in and out.

The two raised positions are for off road or snow.

Ninety percent of the time you will get in and go without even thinking about it.

It might be confusing to read various descriptions on the internet. In use it's no more difficult to use, or understand, than your windshield wipers.

Its a nice feature don't over think it. just leave it on normal and drive around like you normally would any car, if you need extra height its there but honestly the only time I ever even raise up is unusually deep snow or to slide under to work on it for whatever reason. It made putting skid plates on a lot easier I know that. the exit mode is there to drop it down lower but honestly I never use that never really needed it. only real draw back which someone pointed out above is it would likely be an expensive item to fix out of warranty. I think I remember reading somewhere that part of it had been redesigned for 2014 maybe that is why the number of complaints seems less.

Re: Qudra lift air suspension...?

I too was concerned, but considering that "air suspension" has been used in cars for over 100 years and 98% of QL Grand Cherokees are performing normally, I got QL. 1300 miles so far and I love it.
