Possible air suspension issue

[CaptainCJ35]

Dealer is saying the compressor/regulator is failing and needs to be replaced. They weren't able to answer a lot of questions I had, so it didn't inspire confidence and want $2300 to get it done... which is preposterous. Air Delete here we come.

Update. I started working with a local repair shop for a second opinion and/or to replace the Air Suspension. They found a leak in the passenger front air strut, and the compressor they deemed to be ok.

Air suspension works great for me since I routinely go into Boston and park in very low parking garages... I wanted to preserve it if possible. Factory Air Struts seemed to be on backorder with no ETA info available, unless I wanted to pay a king's ransom. As a result, I went with re-manned struts from RMT. This was the air suspensions get outta jail free card.

RMT was good to work with, Kelly was very helpful, and they shipped replacements for both front struts in a few days after placing the order. I had the struts installed and the air suspension seems to work exactly as it should. The compressor only kicks on when it should, and pressures are nominal despite the repair shop not having the ability to fill the nitrogen tank. Which means... yep... my system has been ingesting outside air for a good long while! I will seek to get it purged at some point.

The local dealer had absolutely no clue about diagnosing or fixing the issue with my truck. There are a number of other dealers around, but I will not be going back to that one for any reason.

Final note: It's only been a few days since install, but the RMT struts clunk at slow speed on bigger bumps with some articulation. We could replicate the clunk at the repair shop and it's coming from inside the shock body right as it starts to compress. I reached out to RMT Customer Support but as of this writing I have had no response. It might be the consequence of going with reman. It's livable but not optimal.

When I go bird hunting we drive down some rough farm tracks. I often get clunks with my OEM struts too.

Hello All,

I have been having a similar issue with my 2020 Ram. I’m from Houston, once it started getting below 50 I noticed my air ride compressor would continuously run when i would remote start the vehicle. The compressor would purge then it would stop completely or overheat (I’ve only had this happen once) . I can hear the blow off sound when I drive to work. If I drive with the auto start stop function on when the vehicle shuts off I can hear the blow off sound. But if I leave the auto start stop feature off i don't get a blow off sound.

In normal ride height mode I have no issues. But if I put the system in aerodynamic mode I start having the above stated issues. When the vehicle sits in aero mode (while I'm at work) the driver rear side lowers leaving a slanted stance. But when i start the vehicle or unlock the door it goes back to its original stance. No lights on the dash, no overheating warnings. I took it to my trusted mechanic and he ran a full system test and gave me a receipt with everything the reader checked out.

I thought it could be a leak in the rear suspension. But if I has a leak it should be lowering in normal height also right? Or the compressor would be running continuously to make up for the loss of air or nitrogen

Any help or advice would be much appreciated.

My system started giving me the cooling notice more and more often.
I notice that When driving, after lowering to aero and trying to go back to normal ride height, is when I get the message. The ride can get rough and definitely feels like the truck is hitting the bumpers. Dealer put more nitrogen in it, but issue is still happening. Either they don't care or don't want to look into further.

Sounds like a leak in the system. I would go to a different dealer if possible.
