I had all the same issues, replaced the module and compressor multiple times, had it in the dealer for 3 weeks the last time in. They figured out it was the limit valves on the front air springs, and since they replaced those, the issue has not returned and the quadralift has been working perfectly. It was a constant back and forth, id recommend suggesting that if the module and compressor replacement do not work

Day 41...no resolution. Still can't get the module to program correctly. I was told Friday they were going to fill the nitrogen levels because they thought that may have been the issue. Was suppose to get a call this morning, no call. :mad:

Well a year or so ago I got the same message and the suspension was stuck in the lowest position. It turned out to be a bad compressor and all was fine until today. I got the message again and once again it's in the lowest position but now when the Jeep is off I hear an electrical noise from the right front as if a small motor is running. I have resorted to disconnecting the battery to avoid a dead battery until I can get it looked at. Max Care to the rescue.

Some members have pulled the fuse instead of disconnecting battery. I’m not positive but I think it’s in the fuse box by the passenger door. One of those.

43 days in they now believe it's a bad air compressor. Estimate on replacing the compressor is $1900. This goes on top of the $1400 repair for the suspension module and switch. I found myself owing $1400 without any resolution or ability to turn back the first install. Since the module and switch were installed, there was no returns. I agreed to pay the $1400 and pray the additional $1900 compressor would truly fix the issue.

Day 53...I received a text message saying the vehicle was fixed and ready for pickup. Now I need to find a buyer to purchase all my tears in order to pay for such a ridiculous system. I'll just chalk it up as schooling funds for a hard lesson learned. I hope this is truly the end...we'll soon see.

I told them from the very beginning, I want all the old parts kept. I have yet to confirm this, but that should be the case.

GroundZero,
I hope yours is working correctly now. Yikes, that took forever, I feel for you. Mine is on day 13 and it seems like forever. They filled it with nitrogen and it's holding air. After politely riding their back they have been chasing the problem and I just got a call saying they think it's the control module and they will order today. Amused me when they asked if I wanted it expedited for $15 extra. Well, yes, with MaxCare I'm not paying for it :rolleyes:. They said they rarely see this problem to which I told them maybe at their dealership but they are plenty enough with issues to be of concern. I like my WK2 but this seems like a weak link.

Hi bluetrude,

I'm sorry to hear your Jeep has been in service. If you need any additional assistance, please let me know.

FOLLOW UP: First of all a big thank you to Kori for initiating a Star Case with FCA. Well after 49 days I finally got mine back. After the dealership installed the control module they couldn't seem to get it programmed. When I initially took it in I told them that a couple of years ago the compressor was replaced for the same problem hoping that would give them a clue. Once FCA got involved the engineers eventually told them to replace the compressor. Once they did that problem solved. After riding their back and showing up numerous times in person they provided a loaner car for a month. I figured that would be some incentive for them to get it done.

I'm very glad to hear this was resolved--but not thrilled about how long it took! Please let me know if anything comes up in the future.

So I have a '18 JGC Summit with 1900 miles purchased about 7 weeks ago. I'd left it parked in a garage for about a week while I was away for Christmas. Temps inside there had dipped to the teens recently. This morning I started a road trip. When I started the car I heard this horrible growling noise. After about 30 sec. it stopped and I got the "Service Air Suspension Immediately" message. I started driving; when I hit the interstate it did not go into Aero mode (no surprise). I stopped a short while later; manipulating the QL buttons caused the rear to sag heavily (and I could not get it to rise back up). I drove like this for awhile and then got it to rise up to Off-Road II. The QL buttons started to flash and stopped working; when pressed I got a message like "adjustments not available." The QL dash indicator flashed because OR-II is supposed to cancel at a certain speed--I think 45 mph. So I was planning to stop by a dealership this morning in Indianapolis mid-road trip but lo and behold, the JGC eventually lifted to Aero mode! I stopped, started it, went through Park mode, normal, Off-Road 1 & 2 -- all normal -- just like nothing had happened. Several stops for breakfast, coffee, and Wal-Mart this morning have been fine. Also note that the current temp in Indy is 3 degrees -- about 20 degrees colder than when I started the trip.

So what happened? From reading earlier posts, perhaps there was moisture in the system from the factory that had to work its way out? Moisture condenses when it's cold.

I'm not sure if I even need to take the vehicle in. Since I'm no longer getting error messages anymore, I'm sure I'd be told that nothing can be diagnosed and to bring it in if and when this happens again.

Thanks!

I hope this is what is happening to my JGC Overland 2011.
Feel so sick about this - I live in MN, right now temp is about -4 to -12 and its been around these temps for maybe 2 weeks. A few weeks ago I took in my car for the recall- and they did all they needed to do to it.

Then a few days later I had dirt and salt on my car so took it in for a wash, temps were in the teens then. Four days ago, I got the message Service Air Suspension Immediately - the hydra-lift was trying to work but it was making a pumping sound, I got scared and turned it off. The aero dynamics is not popin up, it now says something like normal drive height.

My question is should I drive around like this, then take it in when its warmer? its running fine but I still have the message showing up.
Reading previous posts sounds like it has something to do with moisture, I could be wrong though. Please help, when my car is sick which doesn't happen often I get sick too. :(

That's how mine sounded!

But since then I've had about 6 cold morning starts below 15 degrees and no recurrence. So even if it was a one-time fluke I'm still curious as to what caused it.

HAD similar issue this winter. Blew the fuse. I think it was too cold and froze something in there. Didn’t help that I had hellla ice build up. Took it to the car wash. Grabbed a pick and went away at the ice. Replaced the fuse when finished and good as new

My '14 CRD has this issue now. Took it to the dealer to find out the compressor has seized and blows fuses when they replace them. I also got the price from the dealer: $2400 for a new compressor and $400 to install and bleed system. It is also not covered under maxcare warranty so that kinda upsets me a little as I buy it off lease and penny up for the "maxcare" 5 year / 100k maxcare and find out that it's not included which makes me now think that they have a lot of problems on older models.

As I do a lot of towing and have to drive up some pretty knarly muddy roads I need it to work. So I bought a new compressor from a friend for $1200 (his cost) and I'll have the dealer install it. New unit has a 2 year warranty so at least that's some saving grace that I won't get hit if it fails again.

The Maxcare plan that I purchased a few months ago states that the "air suspension system" is covered.
