Quadra Lift Air Suspension Failure

I should have seen the writing on the wall. I bought a new 2012 Overland 5.7L which now has 21000 miles on it and luckily it is still under warranty. After reading about problems with the Quadra Lift system on this forum, and others, I thought it wouldn't happen to mine. Well it did when suddenly I got the "service air suspension immediately" message. I had used the system often as it was supposedly designed, mainly the park and aero modes. I brought it in to the dealer who changed the control module. I then encountered the same problem a mile down the road along with a "system cooling" warning. I brought it in again and was told that they will consult with Chrysler on a solution. As of now all of the control buttons constantly blink and the suspension is inoperable but the Jeep is still drivable. Will update on the repair progress but I am TOTALLY convinced that ALL QUADRA LIFT SUSPENSIONS WILL EVENTUALLY FAIL. I wish I never went with it. It is beyond me how such an ill designed system is put out on the market. There should be a RECALL

Re: Quadra Lift Air Suspension Failure

Sucks to hear you're having problems this early. I just hit 23 miles and no issues with the air suspension and I use it daily like you for aero mode, sport, and park/entry. Good thing you're covered as I assume it can get very expensive to repair.

Re: Quadra Lift Air Suspension Failure

Although there have been many reports of problems, when a poll was conducted here last year the majority of responders had no problems. Recalls are typically for safety related items, not convenience features.

For some reason, diagnosing these systems seems to be more difficult than most. Don't let it upset you ... It's just a machine.

Re: Quadra Lift Air Suspension Failure

I had the same fear when planning on my 2015 model in the fall. However the poll showed something like 98% have had no problems. And they shouldn't, since air suspension has been used in cars for over 100 years.

Re: Quadra Lift Air Suspension Failure

Just guessing, but part of the issue is when the QL system fails, it's pretty abrupt and has a large impact, since it's a single system that potentially affects the entire vehicle.

Where as generic shocks/struts, etc. are 4, individual systems, so it's pretty much impossible to have a systemic failure of the entire suspension. You can have one blown shock, but never all of them. One blown shock is bad, but not necessarily fatal to the operation of the vehicle.

This makes failure of the QL system even more likely to draw ire and dismay from customers, especially something like a system leak that can make the vehicle un-drivable.

Who knows how many folks have suspension issues that we simply don't hear about.

The same can be said for folks who have had no issues...it's actually less likely that folks who are problem free with "post" anything since people are more inclined to seek out assistance for problems rather than deliver kudos.

That said, one of the reasons I purchased a MaxCare lifetime extended service contract is because of all the expensive components including QL that potentially could fail and be costly to replace over the 5-7 years I'll likely hold this JGC...

I agree that eventually they all will fail but I would also agree that eventually every part in the vehicle will fail if you own it long enough. Eventually could be a long time. There really is no time limit on eventually. There really have not been a lot of qudra lift problems recently talked about on here.

Re: Quadra Lift Air Suspension Failure

Not very confidence inspiring but I've taken my 2011 hemi in and just got her back recently... I believe this is the 7th or 8th time I have taken her in to deal with the air suspension. I'm considering the possibility of getting rid of it and replacing it with a normal suspension system once my extended warranty is out... because there's no way I'm paying for crap JEEP can't fix. So far I've received the car and no issues but it's only been a few days. *sigh*

I agree with you. Air suspension is a total waste of money. Once it fails... it seemingly never stops failing. If it doesn't fail, you're one lucky sob! Unfortunately, I don't have faith in them anymore and will probably never purchase a vehicle with air suspension ever again.

Re: Quadra Lift Air Suspension Failure

Been in the dealer shop for over a week to diagnose the problem. Was told that the compressor needs to be replaced. Wonder what the cost would be without being under warranty. Am I looking to less than three years until it fails again? I'm not waiting for that to eventually happen. Selling!

Re: Quadra Lift Air Suspension Failure

Eventually yes, but what I meat was prematurely eventually, as compared to the rest of the vehicle's systems. ..and eventually stick the unsuspecting owner with a HUGE repair bill once out of warranty. Jeep paid for their crappy system this time but I'm not waiting around for the next time for it to "eventually" fail again. Good luck to other Quadra Lift owners.

Re: Quadra Lift Air Suspension Failure

The saga continues...compressor and control module replaced at 23,000 mi. I know better than to test the system BEFORE leaving the dealer lot. which I did. I ran it through the modes and it again failed and is undriveable. I can't believe that Jeep still equips these systems in the newer models. I asked the dealer what the estimated cost would be if it was out of warranty. The answer was over $3,500 plus the cost of a rental. I would have to say that Jeep made no money on my sale. Do yourselves a favor and don't buy Jeeps with Quadra Lift. Maybe they will somehow get the hint.

How do you mean "undriveable"? Did the suspension lose all lift? Only other experience I have had with a failed air system was on a Rover. Yeah, it failed but that just meant it was stuck in that height setting. Drove it for months like that. Just wondering, since it is a strong assertion.
