I had the same exact problem this morning. Started the car and after a few minutes I got an error message in the EVIC saying "Air Suspension Failure - Immediate Repair/Service Required". Definitely not comforting to see at the start of my commute. I didn't notice a change in the ride height or overall drivability so I pressed on.
A few things I noticed:
1) I didn't hear the compressor cycle on whatsoever.
2) The system held the ride height and air pressure without issue.
3) There were none of the typical QL warning sign of an impending QL failure (increased compressor activity to compensate for leaks/low pressure, ect.)
Initially, I suspected the fuse for the air suspension circuit had blown. Rather than fiddle around with a sophisticated system (and one of which I'm not too familiar with), I scheduled an appointment with Jeep to bring in the car around noon.
To my amazement, the QL system was fully operational when I started it up to drive to the dealer for my appointment. No symptoms of the earlier issue, no fault message in the EVIC, and no deficiencies in the system's performance.
I was relieved as I really couldn't afford the time of leaving the office today.
Obviously, the QL system is affected by extremely cold temperatures. I can't say if the behavior a few of us have observed is by design or by a design oversight. There is a TSB
issued for the QL system in which our symptoms are sort of mentioned - and it could very well be intended to rectify our exact problem - but the language used is ambiguous, at best. I'm planning to bring in my GC to the dealership this week to have the stored QL diagnostic fault codes read by their equipment and I'll report back. I'm also going to insist they perform the previously referenced TSB.
