It's the Central ADAS Decision Module failing.
It's either the main module or the second module.
For me is the secondary one. But I've seen most of the people failing with their main module.
I remember a year ago this issue was all over the forum.
The issue happens to both 2025 and 2026 MY models, and it seems like a very high-probability failure.
Tell your service guy to look into this on their internal forum.
Must be a ton of KBA about this.

My local service folks, in conjunction with the RAM STAR people, disconnected my FitCamX because they believe the camera system's power draw is causing faults across the ADA-connected systems.

I'm not convinced because the FitCamX system wasn't installed until June or July of 2025 (possibly August), and the ADA issues first started in March 2025.

I also find this suspect because the "Turn Signal Activated Blind Spot View" Setting (Truck Settings > Camera > Turn Signal Activated Blind Spot View) and the LaneSense button keep setting themselves to "OFF" when I start the truck.

There are no codes, warnings, or error messages when this happens.

Look for a lemon law lawyer asap!

Already have one. 7 months into the process.....

Definitely not FitCamX cuz I have had it since 2 days after I took delivery of my RHO.
The issue for me happened roughly 1 month after delivery.
It took them more than a week to figure out what was wrong and took them another 2 for the part to arrive (estimate was 45 days so I got lucky).

Have you had an issue since the Secondary ADAS was replaced?

Maybe related…

I recently purchased a Viofo camera for my vehicle. My plan was to use a Dongar adapter to pull power from the housing in front of the rear view mirror. Easy peasy, right?

Well, before I finalized my camera purchase, I called Viofo technical support to confirm a couple things & they said “We strongly recommend you do not pull power from the rear view mirror area. If you encounter reliability issues with your vehicle’s electronics or the camera itself, we will not be held responsible.”

I asked “What’s the big deal?” They said Viofo has over a million of their cameras installed in vehicles worldwide & their experiential data has proven that using the wiring from that area can cause a multitude of problems.

Fitcam X uses those wires. Is it bad? Well, it CAN be a problem, apparently.

Interesting. I installed a Mangoal integrated cam using the power from rear view mirror a couple weeks ago. No issues…yet.

 

[Faze]

who knows with these trucks.. I never seen low battery causing so many glitches and false readings in any other vehicle, so anything is possible

btw using the same connector for my dashcam as well

 

[Faze]

also dealer just called me, apparently the remote fob issue was connected to the instrument cluster, so they ordered new one. Of course the miles have to be programmed into new cluster so the truck is staying there

I'm at 47 days total (since last June) of truck beaing dealership for service as of today. I still have to drop it off in another dealer after this (the one that has bodyshop) to do the body panel alignment and to fix the separating bottom

 

[eltaco]

I too have been told that I need a new digital cluster. At the time, I was quoted 3mo to let the truck sit at the dealer until it arrives and can be installed. Honestly, each time I have my truck in for service it comes back with the same problem and many times with new problems as well. I’ve definitely gotten to the point where I’d prefer to just deal with issues rather than roll those dice on more maintenance.

I was able to get a 100k mi bumper to bumper warranty through customer retention… which seems like a minor victory when I so desperately try not to make use of their service.

I do have half a mind to just go back to a 10-15yr old truck. I bought my son a 2012 Tacoma, and have to say I’m pretty jealous that it just turns on and works normally every time he turns the key.

The "good news" seems to be they have at least updated the new modules. Hopefully this will now be a one and done for you.

Not for nothing, but the VW Touareg did some CRAZY -ish when the aux battery got low. Many of the smaller modules were powered off that battery buss & indications that made no sense at all would start to happen. Eventually, everybody in the community just knew when weird things would start to happen, the aux battery was toast.

 

[RADA]

Well....

Disconnecting the FitCamX didn't solve the ADA Issues..
Going back into service next week.

That suuuuuuuuuuuuuuuuucks, man! Sorry to hear it.

Sorry to hear this.....you need a good tech and they are just hard to find......

WAAAAAAAY back (1993) I worked in the parts department of Chrysler Jeep Dodge Plymouth dealership and a customers car was having strange running issues and one of the techs was throwing parts at to no avail. Finally the service manager gave it to one of their best and most expensive techs....guy started tracing wires looking for shorts...sure enough found it pinched inside the car.

Techs don't or rarely do the basics, just throw parts at em.

..nah F that, I'm ragingly pissed right now....

As I stated in another thread, the truck has been in for service since June 23rd for three different fault codes. (Blind Spot Monitoring, Auto Emergency Braking, and Active Lane Management).
These faults were making the Active Driving Assist inoperable.

My service coordinator told me via text last Thursday that the recalibration process for these and other related systems shows as successful, but the changes/updates don't take effect. The STAR folks have been brought in to dig into the issues.

She called me yesterday afternoon to explain that when the technician returned from an earlier test drive, the truck spit out THIRTEEN NEW fault codes (a total of 16 codes for this visit!), and she will get back to me as soon as she knows more!



This truck is turning into a toxic relationship. I love looking at it, cleaning it, and driving it. But I'm just waiting for it to stab me in the back.... ...for the 10th, hell, 20th time....

Very depressing, because EVERY other vehicle manufacturer is producing the same overpriced, problem-ridden, over-technical garbage.

Well If you want to feel better'ish

My gladiator has been sitting at the dealer since 11 JUN and still waiting on Jeep to approve the new motor under warranty. They said on Friday, best bet I will have it back end of month or the beginning of next month 4 months of the year........its been at the dealershit. AND insult to injury I paid that fucker off in November and....yeah.

I have been having the Traffic sign and AEB warning lights go on for almost the entire time I've own the truck. I finally got it on video one day and brought it in. After a few days, the dealership believes its due to the leveling kit on the vehicle. While I would typically call BS and press, I asked why . They said that the camera behind the rearview, is actively reading the signs. While I have said "LEVELING" kit, my extra weighted SmartCap also creates a bit of a squat, and the truck definitely points up a bit. I can sort of see that if the signs are just slightly out of its normal field of read, it wouldn't be able to identify. While this doesn't exactly explain the AEB warning, I believe they are tied from a programing perspective. While this may not be everyone's issue, I am curious who else has these errors and has a leveling or lift kit?

I recently had this issue on my truck. My batteries drained while I was away for 2.5 weeks. When I got home, I jump started the truck and in the process I blew a fuse on the BUS. I don't remember which one, but it's irrelevant because you'll need to replace the entire bus. Anyways, the one I blew powered the system that controls the ADAS.

Also get a OBD2 reader that can read CANFD, this will allow you to see all the module, not just the ECM. If you BCM isn't communicating, then the ADAS won't work but im sure the dealership would've seen this if they did a diagnostics on it.

 

[Dcchris311]

Hopefully this helps.

 

[eltaco]

I don’t have anything valuable to add here other than to say mine is once again back at the service center to have yet another look at the same issues my truck has exhibited since my first recall software update.

Misery loves company.

Yup. I spent 17 years in the trades, 10 of them in commercial new construction and commercial service. I made a reputation for myself for fixing things when others failed because I looked for the cause instead of just swapping parts.
