2025 Ram 2500 Rear Air Suspension Issues Already

[TheoHerrmann]

I just bought a 2025 2500 6.7, has rear air suspension. Today at only 800 miles the passenger side airbag didn't want to inflate and sagged the ass end, service air suspension light came on, got it towed to the dealership, waiting on word of the issue.

It does have a BDS 2in level kit thats specifically for rear air ride suspension, and upgraded fox 2.0 shocks with Nitto Ridge Grappler 35s. Kit is posted for reference. Shop that installed it also works with every Ram dealer in my city, said there's no way that it affected the bags. And to have the dealer call them if they give me any ****.

But looking into forums I'm seeing a lot of posts about the headaches of air suspension. I didn't want it on the truck but it came with it. I found a delete kit that goes all the way up to a 2024, I'm waiting on a reply to see if that kit will work to delete air ride completely and comes with programming for the sensor faults.

Has anyone had issues with rear air suspension? Would a proper level kit specifically for air ride cause a bag to blow? (Not sure if it's blown yet, might just be a sensor)

And has anyone deleted their air suspension? Heres the delete kit:

Be careful with what you read because search engines and comments are often obfuscated between the four-corner air suspension system (history of issues) on the 1500s and the rear air leveling system on the HDs (primarily issue-free).

I have the rear air leveling system on my 2015 3500, 10 plus years of towing a fifth wheel, and it has been issue-free.

Yeah I've tried to be as specific when searching. Theres not a TON of discussion on the 2500s but there is some. My main worry is a total failure of the system, which would easily go into the thousands, vs a delete kit, which would cost about $2k shipped.

Nonetheless I'm hoping this is a fluke, something minor like a sensor. Idk if both bags are independently operated, if not then the bag is blown already at 800 miles.

I have more faith in a 2015 truck than a 2025 lol.

Actually the Gen5 1500 trucks air suspension is more reliable than the Gen4 trucks.
There's not many failures that pop up about the HD trucks rear air suspension on the forums. Given the system failed so soon I'd chalk it up as a luck of the draw failure before committing to deleting the system.

Garantee that dealer will say its due to the components you installed.. Not sure why anyone anymore would purchase a truck with air suspension when they have had noting but issues.

Yeah I'm hoping it's just a fluke. I'm also hoping they don't give me a hard time and blame the level kit. Hell when they sold me the truck they even said as long as you don't go over 4in then it won't affect any of the warranty but they'll tell you anything to sell a truck.

I got my fingers crossed on it. I'm not a fan of air suspension, if it was up to me I would of never had it on the build.

Did you get that in writing ? If not, I hope you have a good dealer that is not full of it.

Been the only Ram dealer I've dealt with for years, they're slammed majority of the time because they're really the only high rated Ram dealer in the area. But we'll see, if I have to shell out money if they don't want to warranty it I'll just take it to my regular mechanic that I use for out of warranty vehicles, if they won't help me I won't give them my money.

Agreed, very few issues with the HD air suspension, at least on stock trucks. I'm on my 2nd HD with the air suspension and it's a feature I really like. I don't lift or otherwise mess with the stock suspension though. I hope your dealer stands behind it, but I would not be shocked if they don't. Let us know how it turns out for you.

Yes, the airbags are independent of each other. The system has the ability not only to level the truck but also to make bilateral adjustments, for example, when traveling high-crowded roads.

There isn't much discussion on the HD's air leveling system, likely because it just works and is not a commonly ordered option. I would be interested in hearing what you find out, so please post what the fault was.

Have you inspected the air suspension to see where it failed? It could be something as simple as a fitting coming loose or a tear in the air bladder. I’m not pointing fingers, but you have to dismantle and reassemble the rear suspension to install the leveling kit.

Wow your lucky if you found a good dealer. In my area the better of the dealers is 7 hours away, i will not let the local dealer touch my truck again after the brake caliper fell off in 7 blocks when they did brake work.

That could be a big Clue

I would have the shop fix the loose air line and not even waste time taking it to the dealer to tell you the shop disturbed the line and it was leaking

I spoke to my salesman and finance lady as well, and they said a level shouldn't affect anything and they shouldn't give me any problems with warranty, but they'll need to look at it first. So hopefully I'll find something out tomorrow

Yeah for sure I'll keep you updated, hopefully it's something minor, especially knowing they're independently operated.

Before I towed it in I looked underneath, checked the airlines, the air lines on the bag itself were connected, but it was difficult to chase to the compressor especially with it being low so I didn't dig around too much, I couldn't see the actual bag itself, wasn't able to get the dust cover off and honestly didn't wanna mess with anything on the side of the road. Sensors were connected and didn't look pinched, checked all my fuses to see if they were seated etc.

If it's the suspension shops fault I'd be surprised, they already told me to have the dealer call them if they have any questions. They're a really good shop and well known in my city, but you never know, mistakes happen.

Wow your lucky if you found a good dealer. In my area the better of the dealers is 7 hours away, i will not let the local dealer touch my truck again after the brake caliper fell off in 7 blocks when they did brake work.

Yeah a lot of dealer shops just straight up suck. Even a good dealer shop doesn't compare to my regular mechanics shop, but for warranty issues I have no choice.

Not 100% sure if it was an airline though. I couldn't hear anything hissing like a loose airline. If I was closer to my work I would of pulled it into my shop and taken a better look at it before sending it in but unfortunately wasn't able to.

The shop that did it would diagnose it and send to dealer if it’s warranty. Being the owner of a reputable (only Ram suspension shop on the east coast) I can tell you what would be better for you. If something left us and had an issue I would diagnose and repair same day or say “I’m having it to to the dealer the bag failed and the dealer already ordered a replacement under warranty and are waiting for it to arrive”

I thought warranty repairs could only be done at actual Ram dealerships?

*EDIT*

My bad I didn't understand your explanation originally. You would send it back to the dealer IF it was a warranty issue so they could fix it correct?

I'm pretty sure this is a warranty issue either way. I can't seem to find any reason why a 2in level made for air suspensions and some 35s would cause an issue with one of my airbags. But yeah I could of let my suspension shop deal with it. Thankfully they're being helpful right now and willing to step in if my dealer gives any issues.

My 2500 has the ram rear air suspension too. My truck only had 12k miles when one side would sag, as it leaked down often overnight. So 6 trips to the dealer over 6 weeks, before it was fixed. The root cause on my truck was a defective passenger side bag. Since these apparently dont fail very often, the dealer admitted FCA didnt have a lot of troubleshooting procedures for them to follow. They replaced the air pump, and several modules which did NOT fix the issue. Since my truck favored the passenger side every time it leaked down, I told them to look into that specific bag, they refused until there wasnt anything else to replace. Thankfully mine was under warranty. That bag was around $1k. My rear suspension issue arose at the same time my trans was replaced. I think the fact that my truck was on a lift for a month with the suspension hanging, caused that bag to fail.

I too looked into the delete kit. But this feature is really nice when I tow my fifth wheel RV. And you are right, if not under warranty they replaced about $6k of parts.

********UPDATE********

Faulty airbag, swapped it out, so far so good, was able to find the part at another dealer and fixed today. Covered under warranty

Not my truck but a co worker had the air suspension and it went out three times so he ripped em out and got springs to replace it. Its why i didnt want that when i was looking for mine.
