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.

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.

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!!

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.

I am submitting this complaint about Safety Recall C4B / NHTSA 24V‑896 for my 2018 Ram 2500 (VIN: [XXX] ). I am active‑duty military living in Virginia; the truck is registered in Tennessee. FCA’s recall notice says the brake hydraulic control unit (HCU) may fail, causing intermittent then permanent loss of ABS, ESC, and traction control, and that this “may cause a vehicle crash without prior warning.” My truck shows as affected, but I have been unable to get the recall repair. The notice also states that the remedy is “not currently available” and that FCA will contact me when it is. As of February 2026, more than a year after the recall was initiated, I am still being told that parts are unavailable and there is no firm ETA for when the repair can be performed. In the meantime, I continue to drive with a known safety defect FCA has already acknowledged. My truck’s ABS and ESC lights cycle on and off while driving, consistent with the defect description. This creates real concern about whether ABS/ESC will function during emergency braking or low‑traction conditions, especially given that I use the truck for commuting and towing. I am also aware that FCA is reimbursing owners who have already paid out of pocket to replace failed HCUs, which suggests that replacing the HCU is the recognized fix, even as owners like me are told there is “no remedy available” under the recall. This appears to leave many vehicles on the road with a known safety defect and no timely, practical way to obtain the promised free repair. I respectfully request that NHTSA review FCA’s handling of Recall 24V‑896, evaluate whether FCA is providing a remedy within a reasonable time, and consider any enforcement or additional oversight needed to ensure parts are supplied and repairs completed promptly for all affected vehicles.

This has been a recall for almost 2 yrs now and the dealer is saying no parts available. There are 1000s of RAM trucks driving around waiting for parts. A simple google search shows there are parts available on line. What is taking so long. This should have been resolved a year ago.

Received a recall letter Jan 2024 concerning C4B/NHTSA24V-896. I have contacted the FCA recall assistance center several times since then. They say there is no parts available for this recall. Yet they have not seemed to have this problem with 2019-2026 models. They say I can have the HCU replaced at my own cost and they will reimburse me for the cost. But there is no guaranty it will fix the problem or how long it may last if it does. This causes me problems because why should I have to pay nd Waite on my money to be returned to me in 60 days. I am retired and on Social security and can only afford to put this on a credit and which I would have to pay interest on. It seems you or FCA has any intentions of coming up with a fix for this recall.

VEHICLE SPEED CONTROL
My 2018 Ram 2500 has an active safety recall for the ABS/EBS system that has been open for over two years with no remedy or parts available. The issue was first noticed in August of 2023. I contacted CDJR dealership on how to repair this issue. This is a serious safety defect that directly affects braking stability, trailer brake communication, and emergency handling. Because the ABS module and electronic brake system are malfunctioning, the truck cannot safely perform the heavy towing it was purchased for. When towing a large trailer, the trailer’s electronic braking system does not communicate with the truck, forcing the truck to absorb the full braking load. This has resulted in unstable braking, increased stopping distance, and unsafe emergency handling at highway speeds. The ABS fault also disables cruise control, which significantly increases driver fatigue on long-distance trips. I regularly travel 1,500 miles each way to Florida, and without cruise control I must maintain throttle manually for hours at a time, requiring more frequent stops and reducing alertness. This defect has caused premature brake wear due to the trailer brakes not engaging properly. I was forced to replace the rear rotors and pads at only 32,000 miles, costing me $2,700. This is not normal for a heavy-duty truck and is directly related to the ABS/EBS failure. The unresolved recall has also severely reduced the resale and trade-in value of the vehicle. Dealers discount or refuse vehicles with open safety recalls and no available remedy. I am also paying $138 per month for a Mopar extended warranty that I cannot use to repair this defect because the manufacturer has not supplied the necessary parts for over two years. This is an unreasonable delay for a safety-critical recall. The vehicle is unsafe for its intended purpose, creates financial harm, and exposes me to ongoing risk every time I tow. I am requesting NHTSA intervention to compel Stellantis to provide a timely remedy.

CB4 Recall Some (2017-2018 MY Ram xxx) 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. Been dealing with this issue since the recall got initiated back in November 2024. I call Mopar every month to check on the status and still no parts available. I haven't had any brake failures in my truck or scares, but whoever has this issue has to understand how annoying the constant chime is. Can't use cruise control and worst thing is if you are considering selling your truck outside of a Ram dealer, they won't take it in because of the open recall and privately, who would really consider buying a truck with this issue. My fear is that Mopar (Stellantis) is just putting this in the backburner with no plans on fixing it.

Dash warnings for abs / traction control flicker on and off steadily. Every time the warnings come off it kicks off cruise control. I live in often snowy conditions and I worry that steadily changing traction control systems will absolutely be dangerous. Not to mention the frustrating noises of the alerts coming on Avery few seconds. As I was told by my dealer, this recall has been out there since December of 2024. I’ve been dealing with this issue for months and it is getting worse.

VEHICLE SPEED CONTROL
I own a 2018 Ram 2500 equipped with the 6.7L Cummins diesel engine that I purchased brand new in Iowa. For approximately the last four to five years, my vehicle has displayed persistent warnings including “Service Electronic Braking System,” ABS warning light, and traction control warnings, accompanied by constant audible alerts. As a result, multiple braking safety systems are disabled, including anti-lock braking, stability control, traction control, and cruise control. For several years I contacted Ram dealerships and the manufacturer regarding this issue and was repeatedly told that repair parts were unavailable. During this time, widespread reports of identical failures were being discussed on owner forums and among dealerships. A federal safety recall was eventually issued for the ABS control module, and I received my official recall notification letter approximately one year ago. Despite the recall being active, the manufacturer and local dealerships continue to state that no replacement parts are available and that there is no estimated timeline for when a remedy will be provided. As of today, my vehicle remains unrepaired and continues to operate with disabled braking safety systems and constant warning alarms. This is a heavy-duty truck that is regularly operated in Iowa, where inclement weather conditions including snow, ice, and heavy rain are common. I am concerned about the safety risk posed by operating a vehicle with compromised braking and stability systems and the lack of any available remedy after more than a year under an active safety recall. I am submitting this complaint to document the ongoing safety defect, the prolonged lack of remedy, and the manufacturer’s inability to provide a timeline for repair of this federally recalled braking system.

I am the owner of a 2018 RAM 2500 that is subject to NHTSA safety recall 24V-896 (manufacturer recall C4B), involving a potential failure of the Hydraulic Control Unit (HCU) affecting ABS, electronic stability control, and traction control systems. This recall has been active for over one year on my vehicle. Despite repeated contact with authorized RAM dealerships and the manufacturer, I have been informed that no repair remedy or replacement parts are available, and no timeline has been provided for when the recall can be completed. This is a brake-related safety recall, and the continued inability to repair the vehicle creates an ongoing safety risk. The manufacturer has not provided an interim remedy, loaner vehicle, or alternative solution. I am filing this complaint to document that the recall remains unresolved due to parts unavailability and to request NHTSA review of the extended delay in providing a safety remedy.
