The ABS Control module has had a recall on it for years. I have contacted every Mopar dealership with a 250 mile radius and every single one of them tell me they can not get the part. Although I can personally purchase it for around $400 online. Why do I have to pay for a recall part that I can buy from Mopar but a dealership refuses to comply with the recall.

Vehicle Information: * Year/Make/Model: 2018 Ram 2500 Power Wagon * Affected Component: Electronic Stability Control / Service Brakes, Hydraulic / Electrical System * Associated Recall: FCA Recall C4B / the federal safety agency Campaign 24V‑896 Description of the Safety Problem: The vehicle is completely disabled and non-running due to a high-current internal electrical short-to-ground within the ABS/Stability Control architecture. Attempting to turn over the engine instantly blows the heavy 30-amp Fuse F26. Diagnostics isolated the issue exclusively to the ABS module: when the main ABS electrical connector is unplugged, a fresh fuse does not blow, confirming a direct short within the module assembly. Because this is a Ram Power Wagon, the system failure also cascades into the disabling of vital off-road, safety, and stability control systems. Description of Manufacturer/Dealer Non-Compliance: According to the VIN registry, the manufacturer’s authorized dealership marked FCA Safety Recall C4B (the federal safety agency 24V‑896) as "Completed" on this vehicle. However, a physical inspection reveals that the required engineering remedy was never properly executed. The vehicle is still running the original, factory-defective components. The electronic ABS module physically installed on the truck bears part number 68351453AA. This "AA" suffix indicates the original, defective component architecture that is prone to internal failure and explicitly named in the manufacturer's initial safety report. Per official recall remedy instructions, a complete replacement of the HCU assembly with updated brush materials (such as part 68143491AB) is required. The dealership failed to install the authorized engineering remedy part, leaving the defective component in place while reporting the safety recall as closed to federal regulators. Because this component failure triggers a high-current short-to-ground, it presents an active vehicle fire hazard and has left the vehicle completely stranded.

I received a Safety Recall notice back in XXX for the HCU ABS component on my 2018 Ram 2500 (C4B/the federal safety agency 24V‑896). Subsequently, the ABS component failed shortly after so I took the truck into CardinaleWay Chrysler Dodge Jeep Ram Santa Rosa and they temporarily repaired the unit, but did not and have not had a replacement unit to resolve the recall notice safety issue. As stated on the paperwork, it is typed "Advised customer that the HCU is currently on recall, but the recall fix is not available at this time". To date, there has been no repair of that part made to my truck to resolve this safety recall, but the recall notice was removed by Stellanis on my truck, most likely following a conversation that I had with them last month expressing my concerns for safety when operating my truck and asking for an update on when the part would become available. I believe that Stellanis reported this as "fixed" fraudulently to the federal safety agency and I would like for the federal safety agency to investigate this thoroughly. I talked with the federal safety agency service agent "[XXX]" today about this issue and he assigned reference number XXX for the incident. I have attached the documents as per my statements above for review. I look forward to your reply on this matter.

Drove down a paved road in the legal speed limit (30mph). Hit a bump in the pavement and the dash had large amounts of disabled codes popping up: airbag disabled, emergency braking disabled, power steering disabled, blind spots need service, traction control. Brought it to a RAM dealership where they found 6 active and 51 stored DTCs all tied to the communication to the powertrain and safety modules (4wd, power steering, airbags, ABS). The dealer did not have time to fix it, so another dealership said they would fix it if I drove it to them. That second dealer found 3 pulled out wires in the right front fender liner, plug those 3 wires in and works like new. My safety was put at risk due to the airbags disabling, power steering disabling, and ABS. Another safety concern was at night the blind spot indicators in the mirrors would flash which can distract both the driver and others on the road. Every 10 seconds the dash would flash with a reoccurring warning message for another module needs servicing. The RAM company is trying to claim this is not a warranty issue after I brought up the safety concerns of the fender liner being able to pull on the harness and disable these safety modules.

The truck is under recall C4b for the ABS / Traction control system, which also disables the cruise control. I have called several times and had the vehicle into local dealerships and was told there is still no fix. I asked about trading in the truck and the dealers offered me way below KBB value stating they don't want the truck because of the recall. I ask Ram to help me out and they said there is nothing they can do. 3 times now in over the almost 2 years this truck has been under recall C4B the truck has only engaged the rear brakes during a panic stop causing me to almost crash. I talked with Ram recall department and that told me to stop driving the truck, I told them it was my only transportation. They then told me it's up to a dealership if they want to give me a rental until the fix becomes available, of course the dealers do not. I am frustrated and at wits end, the truck constantly dings at me turning the ABS light on and off all day everyday. I have had no use of my cruise control for almost 2 years, and can not pull trailers like I intended to do with the truck becuase the companies will not pass the truck in their inspections because of the ABS / Traction control lights being on. The lights have been coming on since about December of 2024, and stayed on since Febuary of 2025.

I have 2018 Ram 2500 Diesel that has the ABS Recall and my abs system is not working, No cruise control and No traction control. I have contacted multible dealers multible times and I'm told there is no fix for this problem. I don't understand how they can continue to engineer and build trucks that apparently don't have this problem but can't engineer a fix for this Safety Issue. My problem was first reported to the dealer (1/15/2021) 5 years ago. I bought this truck New to pull a thirty foot gooseneck trailer to haul 18000 pounds of farm equipment for my business. This truck is currently unsafe and really unusable in a safe manner for me and other drivers on the highway. It would appear Ram either has incapable engineers or has just stuck their head in the sand and hope the problem goes away. I currently have an unsable truck that I cannot trade due to a safety issue and Ram can't fix it. What can be done to give Ram a time line to correct the issue? I believe you would agree they have had plenty of time to reengineer the fix. There is 371,000 Ram trucks with this problem, Please help Us owners and the general public on the highways. 371000 potiential deaths due to this problem.
