Re: Qudra lift air suspension...?

I read a guy on here pulled the fuse out when it was in entry/exit mode to keep it at that height.

Re: Qudra lift air suspension...?

Ride quality on the highway is great. If you're in ORII (highest) it'll be stiffer but not overly so.

yes very good highway cruiser and even better since dropping the forteras for Michelins. you really don't get in it and think this car has an air suspension the average person probably wouldn't know it unless you told them. also if you opt for the maxcare extended service contract it is cover under that for failure

Re: Qudra lift air suspension...?

If you look through this site, you will see VERY few people complaining about the QL system. As far as air suspensions go, this one seems to be very well engineered. I really like the ride quality. It definitely feels a bit different than steel springs. I LIKE the fact that it lowers at speed, which helps with mileage and handling. Park and exist mode is great if you have to get Grandma in the car, or just want easier loading in the back. The OR settings give you the advantages of a lifted suspension without the ride and stability issues a lifted vehicle has when you don't need it. It will also self level for trailer towing.

All in all, I can't see any down side to it other than _possible_ long term maintenance issues, which is one of the reasons we got the Liftetime MaxCare. From what I have heard from Jeep and Mercedes service people, the system has been very reliable. Much more so than earlier generation air suspension systems.

Personally, I would suggest driving both and see what you like.

Should I be concerned.? Those that have it.. Do u really like it or is it a feature that could be done without..

I have owned 3 of these with the air suspension now. The 2011's did have some early issues with leaks and failures. Mine had the compressor go bad when it was about a week old. Then I got a 2012 and never had an issue with the air suspension and now the 2014 and have not had an issue with it. The only reason really that I have it is I wanted the Overland and it comes with it. If the Overland could be had without it, I don't know I might have just gone with the steel springs. As far as ride and drive I think that's something where you really need to drive both and see what you like better. I wouldn't say one is better than the other.. They are just different than each other. I could be perfectly happy with the standard suspension. I would also make sure you have a warranty on it because its very expensive to repair.

Just to clarify for people who do not have QL, the Jeep cannot be in Offroad II on the highway; it will change modes automatically.
  • ORII is limited to speeds < 25 mph
  • ORI is limited to speeds < 40 mph
  • Normal is limited to speeds < 62 mph
...and Aero mode has hysteresis:
'The vehicle will automatically enter Aero Mode when the vehicle speed remains between 62 mph (99 km/h) and 66 mph (106 km/h) for greater than 20 seconds or if the vehicle speed exceeds 66 mph (106 km/h). The vehicle will return to Normal from Aero Mode if the vehicle speed remains between 30 mph (48 km/h) and 35 mph (56 km/h) for greater than 20 seconds or if the vehicle speed falls below 30 mph (48 km/h). The vehicle will enter Aero Mode, regardless of vehicle speed if the shift lever is in the “SPORT” position.'

Yes, that's true. For the OP's specific question I was simply explaining how the ride quality feels between NRH and ORII.

I've had my 2012 for about 3 years now and I've had both rear lift shocks replaced because they failed. That didn't make me happy, but I knew that the Quadra-lift would be one of the things that could and, in my case, would fail often. The first time it failed the dealer wanted to rip out my interior in order to check the hoses(!). That would have cost me $2k as that wasn't covered under the warranty. I said "no" and had to get Chrysler involved. I read here on Jeepgarage that it was probably the compressor that went out. So I told the guy to check that but he insisted that it was the hoses. Well, long story short they changed the compressor and that fixed the problem. After that the right rear shock started squeaking. They changed that and not long after the left one started the same thing. That was a year or two ago and I haven't had a problem since.

So, overall I love having Quadra-lift, but expect to do some maintenance eventually.

Hard to answer... if you don't know it is air suspension you wouldn't tell any difference... maybe it is a little softer, but... I don't really know!

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.
You can keep the suspension in normal height mode, but to do so you also alter the shift patterns, e.g. by setting it to "snow" which is really for any slippery surface.

The suspension seems a bit firmer in the aero mode than normal height, where if you run it up high enough to go to aero and then stay above minimum you can sorta compare the two with the normal mode's shift pattern and power distribution balance, since sport also alters shifts and power distro.

The off road2 mode [or just keep hitting the up button in 4lo] is a bit nice if you want to take a gander at something under the vehicle, or are trying to spray wash the underside. It also cuts down on jack time when changing wheels/tires, but you wish they had copied the old Citroen feature of letting the vehicle jack itself.

I would definitely suggest trying Quadra Lift vehicle against non-QL with the same trim/power level to see if you think it is worth it. Definitely put the QL in sport, drive fast enough on crooked roads to get it into aero, then slow down enough to keep it there, and compare that to just driving the slower speed. Off road modes, you may or may not care about. It does go up in the air quite a ways.

You'll never mistake it for a Lotus in any mode, but it does reasonably well for an SUV. Switching from aero to normal mode doesn't seem to heat it up in a PROPERLY set up suspension, even in Vegas or similar grade heat.

An Overland Hemi with QL? Amazing deal? Snatch it.

That QL suspension is largely a Mercedes design...
