Brake Controller Disconnects While Towing 2024 Ram 2500

[DHague]

Truck randomly thinks my brakes are "Disconnected", sometimes within 10 miles of driving, and as much as 900 miles, Re-connects and repeated losses, all lights function, and RV plug is secure in the socket. I have Completely ruled out the brake system on the trailer; replaced Pigtail plug, inspected All wiring and grounding to trailer frame, All four Brake Solenoids have exact same Resistance value with multi meter.
Took truck to Liberty Ram in Rapid City, SD for Warranty service; No Surprise but, "They could not Duplicate!" Would not replace because the controller is not recording a "Fault Cde" even though I am receiving a solid RED warning in the lower left corner of the message center that indicates "Brakes Disconnect" for an extended period of time.
My truck came out of Production in December of 2024, I suspect that I have the same brake control that has a Recall for the 2025's and 2026's. Does anyone have a suggestion on how I can solve this Safety Issue?

Maybe video the warning light to show dealer

Spot on, no "maybe" about it. These Dealerships that can't replicate and won't take a clients word are following Stellantis directions to stall and decline as many warranty claims as possible. With video proof, they will still be hard to deal with, but at least it will move forward.

I offered up video proof, would not except it because of "No Fault Code" in the history, even though the lack of Fault Code could/most likely also be a part of the malfunction of the controller; brakes disconnected AND failing to record the Informational Warning and the Hard Fault indications in the message center.

Then it is time to start going up the ladder at the dealer, Service Manager, General Manager, then owner. If none of that works go to Stellantis and then you have the ammo to file a Lemon Law if you want to. Sure wish we had those in Canada.

I never accept stupid answers, but I am retired, have the interest and time and am well versed in how to make crooked peoples' lives miserable.

Tow the trailer To the /dealer and have them take the test-drive with you to witness the defect.

(addt’l defect is failure to record the fault)

Thanks for the feedback guys; I did some more Innerweb Sleuthing, specifically the National Highway Traffic Safety Administration, and found that the "Suspect period began on July 18, 2024, when the first vehicle was built with a suspect trailer tow module."
Next steps on my agenda:
I will be contacting NTSA tomorrow, as well as the Service Manager at Liberty Ram in Rapid City because the Failure to Record the Faults is clearly an additional defect in the module.
A friend has a 2025 Ram 3500 doing the same issue, but with one exception, he still has trailer brake function even when the Fault Light is illuminated, mine still has light function but not brake function. Serious Liability Exposure to both Stennis and to Liberty Ram of Rapid City.

I would get this fixed and then look for a better Dealer because these guys are clearly not in it for their customers. Known defect and subject of a recall and they still won't treat you right? What a load of road apples, commonly called horse sh*t.

Best of luck.

Yea the fact that they know there is an issue with the trailer brake controller on many trucks, yours is having an issue, but they wont change yours out because it dosnt have a stored code?

Find a new dealer. Period.

My 2026 1500 has this issue. Once in a while the dash will light up for it. But then it might not come back on for weeks or more. Dont know how the trailer lights/brakes react when the dash lights up because i dont tow with this truck. The truck has an open recall for it, i just have to make the stupid appointment with the dealer. Been putting it off since i got the truck 8 months ago haaa.

The other frustrating part is their reply of "Could not duplicate." Really??
What is happening is such a random thing; one of my last trips, it disconnected within 6 miles of my house as I was getting on the Interstate, then never hit again for 1200 miles! Unfortunately, it started again when I was starting my climb to Fourth of July Pass above Coeur d'Alene ID. How much fun is that when you can't trust your trailer will have a functioning brake controller for the decent down the other side??
I have noticed a minor correlation between road conditions and frequency of disconnects; it does seem to start when on rough roads and when it is raining heavily, which leans me to suspect the 7 pin plug on the truck is part of the issue. I Know it is not my male 7 pin plug because I replaced it and I had the disconnect when pulling a 1 yr old dump trailer for 20 miles.

I have contacted the National Highway Traffic Safety Administration in regards to the Open Recall for the 2025-26 Trailer Tow Module losing connection with trailer lighting and/or brakes: Rev. 26V059 for Production Run July 18, 2024 - Nov. 01 2025 and added an additional complaint on the stated defect to include the potential that "The vehicle may or may not record a "Fault" in the Fault Logger History."
NHTSA suggested that anyone having the issue should contact them to have their specific Model Years and Production Runs added to the Recall Report. Especially if your vehicle is failing to record a fault code.
NHTSA: 888-327-4236

Excellent work. That helps keep these skells in line. Wish more folks would put in the work to do this.

My advice until its fixed is when going down any 5-6% grade you do as the semis do by limiting your speed to between 25-30 mph, use your trans 3rd gear, set EB to full mode and then hope your truck's brakes don't give out... Myself I would worry more about the Continental Divide in MT than the 4th of July in ID..

Definitely drive the truck and travel trailer the same as I drove the bigger rigs, especially across the divide between Butte and Helena MT.
