Have had the air suspension for 6 yrs. now on my Limited with no issues either. Probably having the Lifetime “warranty” is warding off any expensive repairs!

Hi @willie64 ,

We are terribly sorry to hear this! Have you visited your dealer since this occurred? Please send our team a private message if you are in need of additional assistance while in service.

This is our 2nd MN winter and it was a cold one. Had issues both winters during the extreme cold. Have the "Entry/Exit" enabled and it got stuck at that level and at Normal height (wouldn't go into "Aero" or "Entry/Exit") a couple times this winter. Thawed it out in a heated garage and found a blown fuse both times (40 amp green J-case at position F05) - same as last winter. Not sure going to a dealer would help as this is an intermittent issue during extreme cold. I expect eventually there will be a major failure of some sort so the primary culprit can be sorted out at that time. I'm guessing the components freeze up a bit and strains the compressor which blows the fuse. It really creaks, groans and pops when it finally frees up. Seems to be isolated to the rear suspension. I now carry a couple spare fuses. ....and I bought a lifetime warranty

Yup the fuse issue. Seems to be happening to quite a few. Had my pump just replaced. Only 2 yrs w/ 23k miles. Had a Mercedes w/ air suspension and didn’t have any issues with it.

Lucky, their open system is notorious for failing after 5 or 6 years. There is quite a cottage industry in Germany to service them.

I was born with nuttin' and I still have most of it.

I guess the question would be. Why did you buy the Jeep? Do you offroad with it? All manufactures have issues. I'm a Honda Master tech. Have worked for Honda for 30 years. Have seen all sorts of problems. The main thing is does Jeep stand behind their product? From what I've seen on this forum It appears they do. I don't own a Jeep as of yet. i'm Here researching to see what their like. So I can make an informed decision in a couple of years.

I recently had the same problem. Bag blew. Just wondering if anyone has replaced the bags with one from an aftermarket company or only from Chrysler. The one from Chrysler is 1400$ and the ones I found online are like 150-200$. Looks like they are identical.

I appreciate you guys putting all this stuff out here. I got this service message yesterday on my way to the train and took it over to my dealership. (2019 JGC Trailhawk, <10k mi). Local service manager told me that this "just happens when it gets cold" and that the message would go away.

24 hours and a heated garage later, the error is still there. Service manager this morning tried to tell me that there was some service bulletin saying Jeep doesn't recommend that people drive their cars under 31 degrees Fahrenheit. I find that kind of hard to believe. (It was about 31 yesterday and 40 today.)

Good to know that my hunch was probably right and everyone else had major issues. Hopefully the service guy won't come back and lazily say it's cold weather again because he doesn't want to bother diagnosing a difficult issue.

This is my first time interacting with their service department, and I don't like having to ask the service manager to say out loud that the company doesn't recommend driving their cars when there's frost on the ground. I've driven Asian badges for the last ten years after leaving Detroit, and I'm really not happy that this is my first experience coming back home.

Worst part was that this guy tried to back up his assertion by saying he's got three Dodge Rams that look like they're going to scrape the ground with the same issue that have never been driven. Doesn't exactly give me a huge amount of confidence in the engineering here.

I think I would ask FCA to confirm the “existence” of that TSB. Recommending that a Jeep (of all vehicles) not be driven at below freezing temps wins the absurdity award so far!

By far most have zero issues. They should at least read the fault codes for you. Otherwise find a different dealer, one that knows how to service air suspensions. I suspect they don’t have a tech qualified to work on them. I would not trust that dealer with an oil change. Go to Jeep.com and contact customer care and complain. Mine has set in a parking lot in -10 and -20 degree weather without issue.

LOL!
In anticipation of the upcoming winter I stopped by the dealer in my neck of the woods (Minneapolis area). I was told by the service manager that the issue starts to appear at temps below -10F. He said they have a "fix" for it now. They purge the air tank and put in nitrogen with an "air dryer additive" used for air brakes in trucks. Now I'm not sure what this additive could possibly be but my understanding is that an air dryer for truck brake is an actual device that the air flows through. Probably packed with desiccant? Perhaps he meant to say that the nitrogen is passed through an air dryer? I don't know but I plan to find out. That being said, I had another fuse blow during the middle of last summer. 80* out. There's additional issues with mine I suspect but they seem hesitant to troubleshoot it without the "problem" showing itself. I'm going to bring it in (with my handful of blown fuses) within the next few weeks and insist it gets resolved.

There was an update along the way that improved cold weather performance in that it eliminated some false alarms. There was also a revised compressor.

Although considered a closed system, the compressor can draw in outside air to make up for leaks. There is a desiccant filter in that make up line.

Hadn't heard before that there is a revised compressor. The dealer replaced mine this past summer after it was acting up anf threw some codes. At least I didn't have to go through any hurdles. They pulled codes, diagnosed and replaced. Had it back a few days later.
