2018 RAM 2500 Driver assistance Problems

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.

The contact owns a 2018 Ram 2500. The contact stated that while driving at various speeds with cruise control engaged, there was an abnormal dinging sound coming from the vehicle, and the cruise control disengaged. The vehicle started coasting. The driver reset the cruise control. The ABS message was displayed. The contact received notification of NHTSA Campaign Number: 24V896000 (Service Brakes, Hydraulic). The failure recurred while on the interstate, on country roads, or pulling out of the driveway. The contact was concerned about losing the vehicle, which was taken to the local dealer, who was unable to repair the vehicle because parts were not available. The vehicle was taken to another dealer Dan Cummins Chevrolet Buick of Paris Service Center (1020 M.L.K. Jr Blvd, Paris, KY 40361), but it was confirmed that the part was not available for the recall repair. The customer service for the manufacturer was contacted, and the contact was advised to drive carefully because the recall failure posed a crash safety risk. The failure mileage was unknown.

I have the active recall associated with the vehicle listed. It’s been nearly 2 years with the active abs service light, traction control light, and inoperative cruise control due to those lights. Stelantis is not very helpful. Will not fixit yet. But says I can pay myself and some or all may be reimbursed. There is no reason it should take this long. Endangering lives potentially. I sent truck pulling all the time. And you buy these things with these safety options that should work. To be taking this long to remedy this. Is unacceptable

I have been waiting on the C4B recall for nearly two years with no parts available still. My truck has no ABS, traction control, or 4WD. This is a 2500 heavy duty truck meant for pulling trailers and heavy payloads. This recall has rendered the vehicle useless. I can't trade it in due to the ongoing recall, it is not safe to drive, I am at an extreme financial loss due to Stellantis' negligence. How has the US government allowed this issue to last for so long? How many unsafe vehicles are currently driving down the road with compromised brakes?

The Hydro Boost Pump Port Tube Assembly (Mopar P/N 04581758AA / 4581758AA) on my 2018 Ram 2500 6.7L Cummins has failed and requires replacement. My concern is that this component is part of the hydraulic assist system supporting critical steering/braking functions. A failure or loss of hydraulic pressure could result in significantly increased steering or braking effort and create a serious safety hazard, particularly while towing, carrying a load, or traveling at highway speeds. I am requesting NHTSA review this component and determine whether similar failures have been reported on Ram 2500 vehicles and whether further investigation or manufacturer action is warranted.

This truck has been built with a brake hydraulic control unit ("HCU") that is susceptible to failure or malfunction which may result in a reduction or change of Anti-Lock Brake System ("ABS")/Electronic Stability Control ("ESC") /Traction Control performance. A failing HCU will initially result in the intermittent loss of ABS/Traction control progressing to permanent loss. Safety Risk The loss of ABS/ESC/Traction control may cause a vehicle crash without prior warning.

The electronic throttle control light and check engine light are on. I took it to a mechanic and had the accelerator pedal replaced. The lights remained on and the truck remains in "limp mode" and will not go over 59mph. The mechanic stated that this is due to the unresolved recall problems with the traction control and anti lock braking system, and the HCU needing replaced. These components and labor are over 2-3 thousand dollars! I have called NHTSA and the manufacturer with questions and asked for a timeframe for a fix and have received nothing.

The recall causes the cruise control to be inoperable, the abs system to be inoperable and causes the warning messages to flash and the audible tone to sound constantly. I am currently unable to utilize the vehicle as intended (towing) because of the braking safety issue.

Vehicle has not has cruise control, abs, traction/stability control for over 2 years. No traction control or stability in the winter is horrible. Not being able to control speed when traveling is inconvenient. The warning lamps illuminated and went away for weeks. Then randomly just stayed illuminated. Abs hydraulic pump has failed. The recall has been open for over a year and a half and no parts or remedy to fix it.

Vehicle is unsafe to drive due to the loss of ABS and traction control. The constant dinging of the warning is very distracting. Stellantis, Ram Trucks, and local dealers do not seem to care that this has been an ongoing issue for over a year and still do not have any parts for the recall.

There has been an open recall on my vehicle for over 2 YEARS ! even the recall states "...may cause a vehicle crash without prior warning." This has negatively affected and is a safety issue which involves: 1) Electronic Stability Control - turns off and on - doesn't work 2) Cruise control - cannot use, turns off on on on it's own 3) Steering - affects the steering wheel when turning the wheel, the wheel vibrates and wobbles 4) Traction control - turns off and on 5) Anti lock braking - turns off on on It is my only vehicle which FCA/Ram knows is unsafe to drive but I must drive to work etc. I cannot resell or trade this vehicle in because of the enormous loss in value since it is not repaired by FCA or who ever owns Dodge Ram at this time. I have on multiple occasions contacted FCA/ Chrysler/ and the dealership about the issue, opened numerous cases about the unresolved issues and attempted to get a status with no remedy or timeline provided by the manufacturer. If my family is in the vehicle and we crash... who can I sue? Chrysler? the dealership? or the NHSTA for allowing an open SAFETY recall to continue for over 2 YEARS!!

I traded my 2001 F250 for this yard art with intentions pf pulling our fifth wheel all over the country. It has sat un-usable for two years. I would happily pay for the parts if they were available. They are not at least that is what the dealer keeps telling me. Milton Ruben in Augusta. The recall is about two years old now and nothing is happening. I can't sell it, I can't trade it,, This is complete BS. And as I understand, there are around 36,000 affected by this??? You can't drive it because of the constant chiming and no cruise control on trips,,

My vehicle has an open safety recall (24V896000) with no available remedy for over a year. I'm not sure why you guys aren't seeing it. The ABS warning light is illuminated, indicating a failure of a critical safety system. I reside in [XXX] where annual safety inspections are required and that date is now here. Despite the defect, the vehicle was passed by a Dodge dealership knowing the ABS system is not functioning properly as there isn't a fix. The manufacturer, Stellantis, has no repair available and no timeline and I've only gotten the run around from their recall department and corporate. I am being forced to operate a vehicle with a known safety defect or not use it at all. This situation leaves consumers without a remedy for a federally recognized safety issue.

Manufacturer Recall C4B and NHTSA Recall Number 24V-896 have not been addressed by the manufacturer. Both recall notices were issued Nov. 27, 2024. The following conditions have occurred in the 2018 Ram 2500 I own. "Vehicles may have been built with a brake hydraulic control unit ("HCU") that is susceptible to failure or malfunction which may result in a reduction or change of Anti-Lock Brake System ("ABS")/Electronic Stability Control ("ESC") /Traction Control performance. A failing HCU will initially result in the intermittent loss of ABS/Traction control progressing to permanent loss." The HCU failure causes the failure of the ABS function, the Traction Control function and the failure of the Cruise Control feature. The failure of these integrated safety features dramatically increase the risk of accident, injury or death. The warning lights associated with the system failure are ABS, Traction Control, and Service Electronic Braking System. The indication for this failure have been occurring since Feb 12, 2025.

No incident has happened yet but I don’t want an incident to happen to get this fixed. The HCU and ABS are not working properly or at all I’m not too sure. The sensors on the truck don’t work. The 4x4 don’t work either. The cruise control doesn’t work either. I need my truck fixed asap.

Was towing with my 2018 Ram 2500 ... truck ABS failed to engage under emergency stopping narrowly missing stopped car in front of me... truck took substantially longer to stop and brakes locked up... There is an outstanding recall on this but RAM says parts are not available... there appear to be in excess of 317,000 large heavy duty Ram trucks on the road, probably most towing heavy loads, with failing ABS and Hydraulic Control Units (HCU). At what point will Ram be made to actually fix the problem and make parts available to their service dealers versus just ignoring the issue??? Now the truck has permanent ABS light on but no parts from Ram to fix???
