2018 Ram 2500: adaptive cruise control problems

Filed Oct 7, 2026 · Brakes, Electrical · IN

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.

This recall has been in effect for almost two years. I have been affected for the past year with almost constant warning alarms distracting my attention to drive. The Chrysler Mechanic did diagnose that my ABS system has failed but t hat a remedy was, and still is not available. In the meantime I rarely my 2500 RAM Diesel because I have no ABS, cruise control or the ability to disable the traction control. The mechanic was not able to turn the alarm off and turning up the radio is not a safe option either. I drive many highway miles and often transport my Grandchildren to and fro. The latter is the reason I bought a heavy duty vehicle for safety. Due to the weight of my truck, without cruise control it is challenging to maintain consistent speeds on the highways and I am a nuisance to most drivers which has caused more than one bad reaction from other drivers. Not to mention the loss of 3 to 4 MPG of diesel. Recently my second vehicle is getting repairs and I am having to use my RAM exclusively. The recall center agreed that I have safety issues with my vehicle and offered me a rental, but after providing the requested information downloaded from the truck by the certified mechanic, I was told that more information was needed. This took place over a period of approximately two weeks where I surrendered my truck to their unsecured lot. At that time I retrieved my truck and concluded that this was a cat and mouse chase. So now I am once again driving my unsafe truck looking at navigating Indiana winter roads. Over six months ago I was the assured that the replacement part was in the final stages of testing and this is the same story today.

My 2018 Ram 2500 has a continuous ABS/ESC/Traction Control failure related to recall C4B (the federal safety agency 24V‑896). The hydraulic control unit (HCU) is failing exactly as described in the recall. The ABS light, traction control light, and stability control warnings come on constantly, and the cruise control shuts off while driving. This is a safety‑critical defect that increases the risk of a crash, as the federal safety agency states in campaign 24V‑896. My dealer confirmed the recall but says the remedy parts are unavailable and may take months. I am driving a vehicle with disabled ABS and stability control because Stellantis cannot supply the required HCU replacement. I am requesting the federal safety agency assistance because the manufacturer cannot provide a timely safety repair. I also have a bad knee and can NOT drive without cruise control.
