Great to hear! I'm remaining optimistic!

Just to maybe help set your mind at ease, the system in the Jeep is designed by Continental. They have been pioneers in air ride technology for over a decade. Their systems are used in Porsche, Rover, Mercedes, Audi, etc. This is the 3rd generation (I think) but the 1st generation of a closed system so I expect there to be some bugs to work out. Also, based on the success of the WK2 I'm thinking this is the widest use of the system so it's understandable that initial bugs will be magnified simply due to the volume. OTOH, that same volume should contribute to a faster solution than if you had a Rover, which sells fewer vehicles in a year than Jeep is selling WK2 per month.

Thanks. Yes I had read this before. However I wonder how many WK2s are really equipped with the air suspension. Sure they sell a lot in total but many are 4x2s (at least in the south) or base models. There are still probably more equipped with air suspension than the imports you mentioned but it may not be as many as you think.

I will continue to do this for as long as I own the vehicle. If it can't accommodate that duty cycle then I'll sell it or lemon law it back to Jeep.

My last 3 vehicles with air ride worked and were used the same way. Luckily I never had a failure they couldn't diagnose and fix.

What I"m trying to say is if you are afraid to use the QL system then you really should be raising hell with Jeep.

I won't buy a "fragile" vehicle, especially an offroad capable SUV. Any modern vehicle shouldn't need to be "babied" or treated with what many would consider excess care. Any and all functions should be able to be used repeatedly over the life of the vehicle.

Re: Quadralift FAILED

On 5-26-11 picked up our new Overland in Kellogg, Idaho and the QL lights were flashing. The dealer said they didn't have a module so to have my local dealer take care of it. Well, the suspenion was stuck on high and the 300 mile ride home was a nightmare. Took it into our lacal dealership and its been in thers since. After a lot of people getting involved they are going to replace the compressor and have it done by Friday. 15 days without the new vehicle and the orginal dealer knew there was a problem but pushed it off to my local dealer. Hope the compressor does the trick.

Re: Quadralift FAILED

That is really crappy service from the dealer. I would have not accepted the car and told them to call you when it was fixed. Not the type of experience anyone should get when purchasing a new car.

Re: Quadralift FAILED

Still no issues with the QuadraLift system. Took the vehicle in today for an oil change. (but they fixed a faulty TPMS sensor in the right rear tire)

Mileage: approx. 6500 BTW... I do NOT baby this thing. I've had it through rock, gravel, mud, a few feet of snow, sand, and nearly 2 feet of water. It was set on Off Road height 2 here: (click on the pic for the video)
Honestly, not tentative about any of it. Don't drive this vehicle like some minivan mom on the way to the mall. Drive it like a Jeep.

Re: Quadralift FAILED

Similar problem here. Was up in the mountains and thought it was funny when I got a message, that read something like Quadra-Lift System cooling down. After which I could not adjust the ride height. The next day it worked, but seemed slow. Then about a month later I noticed that it would take forever going from aero to normal and it would not go into OR1 or OR2.

My dealer took a look at it, recharged and reset the system and sent me on my way. The next day, same problem. Went to another dealer and they reset the system, next day same problem. So now back at my first dealer who has brought in the regional engineering rep to solve the problem. They spent 2 days taking apart my jeep tracing the lines looking for a kink and ended up not finding one. They have now replaced the compressor system and I will be picking up the vechicle tomorrow after work. I'm hoping this is the last chapter in my Quadra-Lift issues.

In other news, my dodge charger loaner hasn't been that bad. By the way, what's your dealer's policy on warranty work? Orange Coast CJD gives rental cars to owners requiring warranty work and charges CJD. Cerritos CJD makes you deal with it on your own and call CJD and fight for a reimbursement. Personally, I drive 30 miles out of my way to go to Orange Coast just for this level of service.

Based on what it looks like on this forum a good deal of us are running into this issue. My Jeep is just about to pass the 20k mile marker (less than a year), so it's definitely gone through its paces since I've bought it. (no off road mileage yet though)

Re: Quadralift FAILED

Advice wanted, if possible.

Over the past week or so the QL has been taking increasingly longer to rise. Today, however, it took over 15 minutes to go from Park to lower offroad setting, and after nearly another hour of blinking it still couldn't get all the way up to higher offroad setting, which is where I normally set it to change oil.

It goes down quickly, as before, but increasingly isn't able to, well, get it up. And it's only got 11,200 miles.

Anyhow, I have to go into the dealer next week anyway about a windshield issue, so this needs to be added to the to-do list.

So, any thoughts about this from those who have had experience with these symptoms would be greatly appreciated. What I'm afraid of is that there is a leak or something else causing the problem, but that the "cure" will be to recharge the system, leaving it to act up again some weeks from now. Murphy's Law, this would be during a long trip with fixed deadlines!

Re: Quadralift FAILED

Well its most likely low on nitrogen or has a bad compressor. I really don't understand the 15 minutes because usually after a minute or so of trying the system will time out and you would get the service air suspension message or the compressor would overheat and you would get the cooling down message. Will it go up to OR2?

No, the console LEDs just flash while the EVIC yellow icon points up, and visually it seems to be going up in tiny increments, or at least rocking slightly, but never quite gets to the point where it finishes getting to OR2 and the LEDs and EVIC icon can quit as usual. No overheating message, either. It's like a winded runner trying to do the last bit to cross the finish line, but just can't quite make the last few yards yet doesn't give up.

I believe the EVIC gave a very quick overheating message several days ago when it was going from Park (wife likes this) to normal height, but it came and went so fast I almost thought I was seeing things so put it out of mind. No such message since.

Re: Quadralift FAILED

Looks like there are some issues with QL in 2011 . What do you guys think, did it get resolved in 2012 ? I am looking into 2012 overland , but after reading this post , wondering if I should wait for 2013 ? Hoping that 2013 will have no QL problems .
