Immediate Air Suspension Service/Repair Required

This is the message that appeared on my info screen today. My wife was backing out of the garage, and all kinds of weird noises came from the engine compartment or trans area. What the @#&! was that? I told her to park it and I would check it out later. Well, I took it for a ride around the block and everything seemed fine. When I shut off the engine, I noticed the message about Immediate Service/Repair required. I went to the trusty owners manual, and read that a fault has occured in the Air Suspension System. Finally went to the trusted Jeep Forum where I read some horror stories regarding this Air Suspension system. Yikes! I knew that this system was going to be trouble when I first bought my 2011 Grand Cherokee Overland with all of those fancy features as standard equipment on it. Can anybody relate to this problem for me? It sure sounds like I will end up taking it to the dealer (ugh!) for repair.
Any harm with driving it until then? Please advise. I love my Jeep Grand Cherokee, bought it new. Only has 24k on it. It's been babied since I have owned it. HELP!

I've been having problems with mine for the past few weeks. Still driving it, even with error messages. Was at the dealer today but it's not fixed yet. As long as you don't lose ride height you can drive it, but you should get it looked at soon, especially if it's still under warranty. Mine isn't. :-(

There are a couple things, but the most likely scenario is the compressor overheated. When it overheats, they usually start making that clanking noise and eventually shut down. Everything seems to be back to normal, but they usually overheat because of a slow leak, and if its not checked out it could easily progress to failing altogether. There have been a couple on here that had compressors clanking once in awhile for years while others end up with a failed compressor in a short time.

There could be a bunch of other things going on. The dealer should be able to read the fault code that set the service required message, and then have a better idea of whats going on.

I just got lost in thought. It was unfamiliar territory;

Thanx for the replies. At least now I know a little bit more of what the problem may be. The thing is, why did it happen? I am not an off roader. I doubt if I pushed that button to raise the vehicle height more than a few times since I have owned this Jeep. I do remember that whenever I would start the Jeep, the height would automatically adjust by itself, after sitting overnight in the garage. I would normally try to fix little things that go wrong, but this sounds way to complex for this 70 year old man to work on! I'll have to go buy another ticket for that $1.4 Billion Dollar Powerball Lottery this week.

You probably did nothing to contribute to the " problem". May just be a slow leak that needs to be repaired .... And as CC said , get it looked at soon before it leads to an expensive fix ( like the compressor). Your repair cost range estimate is $200-$2000 at this point .

Yeah, the slow leak may have progressed a bit to the point where the compressor is not liking it. If you want to try something simple, spray/brush some soapy water on the air fittings located on top of the front shock towers and look for bubbles. If you get bubbles you may have found the problem, but you will need a dealer to fix it as draining, fixing the leak and refilling the system is not something the average backyard mechanic can do with the tools on hand.

when it did that my compressor failed and it cost me 2000+ to fix. That's before I bought an extended warranty... sadly.
And obviously nothing has failed after I bought the warranty eh.

Hey mojoman,

I am sorry to hear about your recent experience with your Grand Cherokee. TSB 08-034-12 may relate to your vehicle:

SUBJECT:
Flash: Service Air Suspension Message And/Or U0415-00 And/Or C159E-15 Set
OVERVIEW:
This bulletin involves reprogramming the Air Suspension Control Module (ASCM) with new
software.
MODELS:
2011 - 2012 (WK) Grand Cherokee
NOTE: This bulletin applies to vehicles equipped with Quadra-Lift (TM) Air
Suspension (sales code SER) built before May 1, 2012 (MDH 0501XX).
SYMPTOM/CONDITION:
The customer may experience a “Service Air Suspension” message. Upon further
investigation the Technician may find that U0415-00 Impliable Data Received From
Anti-lock Brake System (ABS) or C159E-15 Air Pump Temperature Sensor has been set
active or stored.
Also if the vehicle is driven in extremely cold temperatures (-30C/-22F) the ASCM should
be updated with the new software. The new software will allow the air compressor to
continue to operate until -40C/-40F.
Updating the software will correct the conditions listed above.

Good catch Ryan, glad you are around.

So mojoman, you should check with your dealer to see if that TSB applies and if it was done. They don't automatically load new software/firmware unless you complain about something it covers. Dunno if it would fix your issue permanently, but may be worth a shot... but given that you are losing enough ride height overnight to notice, it may be a small leak.

Does the suspension/car lower over time after you turn it off?

If you hear air escaping, it may be a fitting, hose, or airbag leak. The compressor overheats trying to keep up with the air loss and you get the error message.

Hi Pooki12,

If you have an appointment scheduled, please let me know in a private message with your VIN. I can set you up with a case and a case specialist to assist through the repair process.

My 2012 Jeep GC constantly does "Immediate air suspension required" I change a fuse *j01* and its good for a week tops.. Have had it to the dealership 5 times and they can't fix it.. They leave it in the garage overnight, change the fuse, charge me 300 bucks and say its the best we can do.. . .

All summer it worked fine, no problems.. Soon as the perma -10 Canadian winter set in, it acted up again.
