While traveling approximately 65 mph on a two-lane highway, I crested a hill and encountered a vehicle stopped in the roadway waiting to make a left turn. When I applied the brakes to avoid a collision, the vehicle's Anti-Lock Braking System failed to function properly, causing the wheels to lock and the truck to skid uncontrollably. To avoid striking the stopped vehicle, I was forced to take evasive action and steer into the ditch. Fortunately, I was able to avoid a collision, but the incident demonstrates a serious safety hazard associated with this recall condition. The vehicle is currently subject to an open recall related to the ABS system; however, the local dealership has informed me that the necessary replacement parts are unavailable and cannot provide a timeframe for the repair. As a result, I am left with a vehicle that is unsafe to operate and poses an ongoing risk to myself and other motorists. Additionally, the unresolved recall has significantly diminished the vehicle's value. With multiple warning lights illuminated on the dashboard and a known safety defect that cannot be repaired due to the lack of available parts, I am unable to sell or trade the vehicle at its fair market value. I am requesting immediate action to address this safety issue and provide a remedy for owners who are unable to have their recalled vehicles repaired in a timely manner.

What owners say
I had to hard brake on a damp roadway at about 50 mph. The truck began to rotate and skid. I had no control over the vehicle until it stopped. The dash lights came on for a failure of the brakes, abs, traction control, and stability control. All of the lights went off then the truck seemed to drive normally. A short time later the lights came on and would not go off. Took the truck to the dealer. The hydraulic control unit was bad and was replaced. This did not fix the truck. Now it needs an abs control module. The truck remains at the dealer awaiting this repair. This appears to be a problem in the previous model year Ram 2500’s and it looks like my 2022 is affected also. There are recalls for these trucks but not for my model year.
I own a 2025 Ram 2500 that is affected by Recall 03D involving the Trailer Brake Control Module. This recall is related to a potential failure of the trailer braking system and trailer lighting system, which creates a serious safety risk while towing. I regularly use this truck for towing, and due to this issue, the vehicle may not safely tow trailers, increasing the risk of an accident. I have experienced this issue while towing, all lights will shut off on my trailers and warnings that the trailer has been disconnected repeatedly pop up. Then the lights will flash back on just to repeat again. After this happened the first time (last year), I took my truck in to have them run diagnostics and they were unable to find anything wrong, suggesting it could be the trailer, and now the recall is here. I have contacted my dealer, but the replacement part is not available and has an expected 55 week leadtime due to Stellantis allowing dealers to order only one module per week. There are 55 customers in line ahead of me waiting on this part for their own trucks. This leaves me with a vehicle that cannot be safely used for its intended purpose. I am requesting that the manufacturer expedite parts availability and provide a timely resolution to this safety recall Stellantis should not be allowed to sell anything while all of the current trucks on the road are unsafe.
The contact owns a 2018 Ram 2500. The contact stated that while driving at an undisclosed speed, several warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed with ABS failure. The contact was informed that the ABS needed to be replaced. The vehicle was not repaired. The contact was informed that the failure was a known failure with similar vehicles. The contact later received notification of the federal safety agency Campaign Number: 24V896000 (Service Brakes, Hydraulic); however, the part to do the recall repair was not yet available. The vehicle was taken to the dealer several times; however, the contact was informed that the part was not yet available. The contact stated that the vehicle was unsafe to drive for long distances because of a persistent failure. The manufacturer was made aware of the failure. Additionally, the contact was informed that the dealer could repair the vehicle if the contact paid out of pocket for the repair. The failure mileage was approximately 96,000.
My truck has had the issue stated in recall C4B since November of 2024, per the recall a solution was to be provided by first quarter of 2025. It is now first quarter of 2026, the recall still shows no parts available, dealers state no parts are available and this is a ridiculous amount of time to remedy a safety recall. Truck currently has multiple lights/issues related to the problem, no traction control and no cruise control for over a year and a half now. This problem needs to fixed ASAP, it's ridiculous.
All warning lights flash for trailer when connected. ( CHECK TRAILER CONNECTION, TAILER BRAKE DISCONNECT, SERVICE TRAILER BRAKE SYSTEM) More active when dark out.(early morning, nights). Same error with different trailers.
The contact's son owns a 2018 Ram 2500. While the son was driving at an undisclosed speed, the brake pedal was depressed; however, the vehicle failed to stop as intended. The vehicle eventually slowed down and came to a complete stop. The contact stated that several warning lights were illuminated. The owner had received notification of the federal safety agency Campaign Number: 24V896000 (Service Brakes, Hydraulic); however, parts were not yet available for the recall repair. The vehicle was taken to an independent mechanic, where it was diagnosed with a failed Hydraulic Electronic Unit Control. The contact's son was advised to contact the dealer for assistance. The dealer was made aware of the failure. The contact's son was informed that the vehicle was not a pickup. The contact's son was informed that the repair could be performed now if the vehicle was not a pickup. In addition, the contact's son was offered the option to pay out of pocket for the repair and wait to be reimbursed when the remedy became available. The manufacturer was made aware of the failure. The contact's son was informed that the parts were only available for pickup trucks. The contact's son was informed that he could pay out of pocket for the repair and wait for reimbursement. The contact stated that the vehicle had been inoperable since November 2024. The failure mileage was unknown.
Trailer lights not working properly, the marker lights flash when turn headlights on loss of brake and turn signal lights. Hooked another ram 2500 up and did same then hooked a 2013 ram and a 2021 Yukon up and all lights on trailer worked as it should. Have contacted dealer they are saying they never heard of, then at another dealer they are saying they have 4 rams with this issue and it’s with the trailer module and one was even melted. Saftey issue to me because if I’m driving my camper with my kids in it and we have no proper lighting to avoid being hit or if it melts and causes a vehicle fire
Purchased above vehicle on 7/12/25. Was advised no towing for 1st 500 miles. At 712 miles, I hooked my fishing boat up to the truck to go fishing. Initially, truck did not recognize my boat trailer lights (marker and tail lights). My previous truck was a 2023 Ram 2500 rebel that never had an issue with connecting my boat trailer electrical system. All lights worked as should. I still have the same boat trailer as previous(2020 shore lander trailer with led lights). The new procedure for my 2025 Ram 2500 is to disconnect the 7 pin trailer electrical connector to the truck, stop the trucks engine, reconnect the 7pin to the truck outlet and maybe it will, maybe it will not work. There has been times I've had to stop and restarted the truck 8-10 times before the trailer is recognized. Once it is recognized, I have little or no faith in the trucks electrical system to safely tow my boat to go fishing. I also check all brake, hazard and turn signals are functional on the boat trailer while still in my driveway before entering onto a main highway, but I have no way of checking to see if the trailer taillights are properly functioning while traveling on any roadway or highway. This intermittent function can cause a serious hazard not only for myself, but for other motorists who do not see the trailer lights, turning signals or braking signals. On 8/4/25, my Ram truck went in for service at Diehl Ram Jeep Chrysler in Grove City, PA for analysis and repair for these trailer lighting connection issues. Service tech at Diehls "reflashed and updated" the ECM which did not fix the problem. I have another appointment on 8/11/25 for this issue to be escalated with Ram Customer Care.
Mopar part numbers 68143491AA Control-Anti-lock brake system and Mopar part number 68347098AB Module-Anti_lock brake system both failed and were replaced/repaired by dealer under warrranty where I purchased the truck. Truck had 8,223 miles on it. Brakes and traction control was compromised. Numerous warning lights and warning tones were observed.
