2012 GC Air suspension failure

Greetings All,
9000 miles on a 2012 GC Overland. The first time we had bitter cold (-10F), I had a warning along the lines of, "System malfunction....Must cool off before using....Immediate service required" when it tried to change height. Has anyone else had this problem? Also, since I don't have a lot of confidence in the air adjust system, is it possible to substitute with conventional shocks if worst comes to worst???
Also, in the cold, my tire pressures dropped by 10psi all around. I thought nitrogen wasn't supposed to be so temperature sensitive.
Any thoughts? Thanks, CH

There have been a handful that have seen this message when it got extremely cold. Once things "warmed" up they seemed to return to normal.

-10 = Bitter Cold? We've had -40 and colder and it works alright. I think I've seen that message once in the 2 years my Wife's had her Overland.

I had the warning "Service Air Suspension System" show up on my display on my 2014 GC Overland several weeks ago. Brought it in the dealer to repair it for the day (rental car). They called me up and told me to pick up the car, that they had to order a Air Suspension module. It's been 1.5 weeks since then. I called the dealer yesterday to get a ETA on the part. They said maybe by March 7th but no promises. I live in Orange County, CA so the weather isn't the problem. Hope it's the module.

The air suspension on my 2011 failed two weeks ago during a snow storm. Mine was worst case scenario. By the time I got it to the dealership it was riding on the bump stops, looking like a lowrider. Apparently the module that controls the air suspension system failed, causing the compressor to run non-stop. The only way I could get the compressor to stop was to pull the fuse. They replaced the module and compressor, under warranty fortunately. It was a $5200 repair.

Interestingly, the service guy indicated that the problem was related to the cold weather, although it may have been 25-30 degrees when it failed. We don't see negative temps in NC. He claimed that the new system would not have this problem.

My warranty expires in a few months. I'm really concerned about the air system failing again.

There are a lot of them on the road without issues, but you could think about chrysler's extended warranties.

Get the lifetime warranty. Piece of mind. I've had lots of issues with my 12 overland. Probably would have gotten out of it if I didn't have the lifetime warranty.
