*200, 000 mile update coming soon! ...probably* 🤣

You did a good job of trying to narrow it down! I don’t have the air ride on my 2020, guess I’m happy about that, but I can’t think of anything you haven’t already thought of yet. I’m definitely waiting for the next video to see if you found the culprit! Good luck bud and keep these great vids coming!!

I experienced this on my 2014 Ram 1500 Laramie with the 4 corner air suspension. It was still under warranty when it occurred, so my local dealership had to track down the issue. The issue only occurred when the temps were very low, under 10 degrees F. The answer the dealership gave me was that the compressor was overworking and has a fault protection circuit that shuts it off. When that fault happens, if the valves to fill the front, or rear, are open, it will let the nitrogen escape back into the reservoir tank. Typically, since there is more weight on the front, the dealership said that is why it seems to happen to the front, and not the rear for the droop. After the truck warmed up, and the compressor was able to reset itself, it worked perfectly like nothing had happened. Hope that helps with maybe tracking down your issue.

Don't know if you figured this out yet or not, but if you have leaky bags it's often hard to detect unless the vehicle is off the ground. Reason being the leaks usually will develop within the folds of the bags. Temperature, load, incline, etc will affect if the bags leak or not.

So try jacking it up so the wheels are off the ground, then retry a soap bottle spray test.

I dad similar problems. Started out with a wheel dropping over night, long story short. It ended up being an internal leak inside valve body. These starters are a closed system, but not really. They do vent/take air on which in turn introduced moisture. One thing I had done every winter was get the system purged at dodge. It always would work good after that for a while. Anyways my dealer bought it off me “ 17 longhorn” and now I’m in a non air susp 22 rebel. I’ve watched all your videos as I love these trucks and your content is real world. I’m in Alberta Canada and it might be a tad colder here and cold weather brings out the gremlins in these. Anyways I’ve zctudlly been amazed that your ram’s air susp has worked as long as it has. I had my 17 for 5 winters and It took a trailer ride to a dealer every one of them, some times more

Your truck hitting 200k will make Scotty Kilmer Mad. According to him, his celica can tow entire planets, drive on the ocean floor, get blasted by 5 consecutive mini nukes, and can swim in magma and still won't break.

Evening Justin. About the only thing I can think of, is a wire rubbed bare or has a nick in it and comes into contact with something at the right time to cause that bag to deflate. Hope it gets figured out sooner rather than later.

After a dealer misdiagnosis and repair weeks prior, I was still getting the dreaded “air suspension needs servicing light”. Long story short, it was finally determined that it had condensation in the lines that was more likely to drop the air suspension during colder weather.
My air suspension started failing at 100, 000.
Aside front spending an arm and a leg on replacing the entire system, because of the “water intrusion”, there is no permanent solution once it starts having this issue.
I ended up converting the air suspension to a standard system.
It doesn’t ride as smooth (rides more like a truck now) but it still handles well.
I am content with my decision.

Had my Rebel nose down, a** down on different mornings.
You don't have a leak.
What you have is a gremlin in the computer system.
Try thoroughly re-working/cleaning the ground connection on the driver fender from the battery.
Worked for me.
edit: the BCM and CAN bus comm`s can go spastic with poor ground connections or low voltage from a weak battery causing all kinds of trouble.

Hoping to see the 200, 000 update soon! Would be nice to see a recap of all of the issues, and non issues with the truck. Looking forward to see what comes next.

[vinniecorleone]

I love your Spock-like pure logic in attempting to discover the culprit of the air suspension front corner drop, excellent process of elimination, always informative & entertaining my friend! I feel better & better about my 2021 Limited with every video upload man!

[scotthenson]

My 2019 Bighorn (158k miles) started running the compressor a lot just before it failed. The nose dropped and would not recover. The front was setting on the bump stops. I had to have the compressor replaced. Fairly expensive and RAM had none available for over two weeks back in 2021. Even though I had this issue, I still love the ride of the air suspension and would get it again.

[DavidKrzyzanowski]

It is a slow leak in the bag hose connection you should first for the bag up front. It will hold pressure, but if you move it a little and do your spray test, I bet it leaks. I have a 2011 Jeep Grand Cherokee with the same air ride suspension (195, 000 miles) and had the same issue. Once I replaced these little connections, I worked perfectly, no more mysterious drops.

[shockracer]

As one that is on their second compressor revision 4. If you notice that your compressor is getting louder, it might be going out. 4 years seems to be the average people are getting out of their compressors. I'm on year 5 with the second one. My compressor has become much louder over the past year and has been struggling/taking longer to lift the truck with loads or increasing the height.

[Havocs]

I have had it happen to all sides of the truck. I'll come out from an 8 hour work day and it will be tilted. Oddly enough, the truck is alway tilted to the east and it only happens on sunny days. I kinda feel it is a heat issue with the sun. My tires do the same thing (nitrogen as well) with the sun beating at them. It's fairly odd though that the struts are tucked under and don't have direct sunlight on them.

My other question is while driving on a colder Wisconsin winter day, usually driving up the east side shore of Lake Winnebago, I will get a notification that the "Air Ride System Needs Service!" After a few miles, it shuts off.

Another thing it does, driving or parked with ignition off/on, it will blow off pressure like a semi air brake system when it is flushing moisture from the tank. I wonder if there's a correlation with that too.

The master RAM tech at my dealer said everything checks out and they have purged and refilled the suspension system with nitrogen but he likes how I keep monitoring it as well and I talk to him monthly.

I love this truck and not willing to get rid of it yet. I have 120K on my odometer. So I will keep fixing it and driving it till the doors fall off or the RAMCharger comes out.

[JerGossett]

I have 2016 rebel 95, 000 miles... same issue... although my notifications alerted me.... I put my truck in the garage and put heat on it and all suspension levels are the same, yet alert is still notifying me of known issue... I can't raise or lower but all bags are inflated..without the compression kicking on

[lebaroncars]

We have a 2011 jeep grand Cherokee with air ride system that shop diagnosed with a weak compressor, needing replacement, suggest you find your compressor relay and replace it, I replaced ours in the jeep and working perfect now . I broke open the old relay and found the contacts burn't and worn from use, now keep in mind a bad contact will equal lower voltage to the compressor due to contact resistance due to burning or pitting from years of use .

[domenicmonzingo]

So did you ever figure out what's going on with the air suspension problem? I have a 2016 Ram Rebel doing exactly the same thing. Problem is my extended warranty is just about up and it's been to the dealership 3 times and those clowns can't seem to figure it out. Was hoping you figured it out so I could steer them in that direction.

[bradboutilier]

I wonder if there is a check valve between the bags and tank that is sticking open sometimes causing it to "leak" down back through the compressor

[alexanderabboud]

Well this is just confusing. But ram did a great job with the air suspension for it to last basically 200, 000 miles
