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 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.

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.

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.

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.

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: [[redacted]] ). 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.

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.
