There was a Recall C4B/the federal safety agency 24V‑896 on my 2018 Ram 3500 truck back in 2024. The part HCU/ABS unit that was recalled went out on my truck on or about 6/23/2025. Went to dealership on 6/25/2025 they told me that they have an old model part NOT the new updated recall part in stock. Due to safety concerns, I agreed for them to fix my truck, and they explained to me that FCA US LLC would reimburse me the cost, which I did receive the cost back. I have on many different occasions emailed them through their web site asking to be notified about the replacement part for my truck, when available. I have never received any notice until 10/19/2026 stating that my truck has been fixed as of 9/28/2026 and there was nothing else I needed to do. After first call with FCA recall center, they said that my truck was fixed according to their service records. I told them that the new replacement part was never installed and that someone made an error on their end. After talking with them I told them I wanted this escalated to someone higher up. A supervisor called me today 10/21/2026 and basically said the same thing that according to their system, part was fixed. The invoice that I submitted to them for the reimbursement says that the recalled NEW replacement part was not available on 6/25/2025. I have all the documents needed to prove that the parts were never changed with the updated part. I asked them to show me documentation on what dealership said my part was fixed, they said I would have to talk to my dealership, so I did twice with Opelika Ram dealership and they have no record other than the old part being put on 6/25/2025. FCA recall center refused to give me any document or tell me who closed out this recall C4B/the federal safety agency 24V‑896. They however said that they would give me a 2-year warranty on the old part starting on 9/28/2026; it took 7 years for the original part to go bad. My truck is still a safety concern because this Hydraulic Control Unit /ABS can go out at any time.

Loss of Brake Performance
The Office of Defects Investigation (ODI) opened this investigation on November 28, 2022, after receiving 134 reports from consumers alleging an intermittent or permanent loss of braking performance in certain 2017-2018 Ram 2500-3500 pickup trucks manufactured by Fiat Chrysler Automobiles (FCA). The alleged failures continued to occur at a steady rate across both models, at all speeds, with limited detectability. Consumers complained that the Anti-lock Braking System (ABS) warning light illuminated on their vehicles. The ABS module works in conjunction with the Hydraulic Control Unit (HCU), an electromechanical device that controls hydraulic pressure to the individual wheel brake assemblies, to manage braking forces during emergency stops. During this investigation, ODI received over 2,500 consumer complaints concerning ABS or HCU warning lights that illuminated on the dashboards of their vehicles. Many consumers described also having trouble with cruise control, traction control, or electronic stability control. Of the complaints received, over 50% mentioned that the ABS or HCU warning light was intermittent in nature. ODI learned that in January 2021, FCA was aware of a problem with the ABS pump motors on the subject vehicles. FCA had been working with the supplier, ZF, on an issue concerning swelling of the brushes inside the motor. According to a briefing given by ZF to FCA on January 15, 2021, the ABS, electronic stability control (ESC), traction control system (TSC) and other functions utilizing the motor would be disabled in the event of a problem with an ABS pump motor. ZF also informed FCA that Slip Control would be inhibited with the driver warning lamp illuminated, base braking would not be affected, and FMVSS stopping distance requirements would still be met. In order to better understand the potential consequences of the brushes swelling and the disablement of the ABS, ESC, TSC and other functions, ODI requested that the federal safety agency's Vehicle Research and Test Center (VRTC) conduct testing on a subject vehicle with a faulty pump motor installed. During the testing, VRTC found that as the brushes started to swell in the motor, the warning lamp could illuminate intermittently, causing confusion to drivers. Although the warning light illuminated intermittently, VRTC discovered that the pump was not working properly regardless of the warning light status. In this condition drivers might think that their vehicle is operating normally when the warning light is off, but instead, the ABS, ESC, TSC and other functions supported by the pump will not work. Following a series of meetings with FCA to demonstrate the findings ofVRTC's testing, FCA conducted an internal review and on November 27, 2024, FCA submitted safety recalls 24V‑896 and 24E-100. In view of the recalls being conducted by FCA, ODI has closed this Preliminary Evaluation. The Agency reserves the right to take additional action if warranted by future circumstances.

Fiat Chrysler issued a safety recall in 2024. The FCA recall number is C4B the federal safety agency recall number is 24V – 896. This recall was issued almost 2 years ago, but Fiat Chrysler has made little to no effort to make parts available. I’ve attempted to have this recall repaired four times, and I am attempting again today. The dealership and Fiat recall department tell me there are no parts available. Per Fiat Chrysler, they are rolling out parts in stages. They are still working on 4550 & 5500 class trucks, two years later. They are rolling out the recall regardless of whether a truck is experiencing alerts on their dashboard or truck problems. Trucks that aren’t experiencing problems are getting parts before trucks that are, if they are not part of the current rollout. For over a year now, I’ve had the ABS light on my dashboard illuminated, with no antilock brakes in my truck and the truck constantly makes chime sounds while driving. Burlington Ram, in Burlington County New Jersey, has confirmed my lights and chimes are due to the part being replaced in this recall. I’ve complained directly to Fiat Chrysler and requested they make parts available. Two years later, they still will not make a part available although some dealerships somehow sell the parts to people who want to pay cash for them. Two of my coworkers have done this because their vehicles are out of warranty and they don’t want to wait for the recall. Fiat Chrysler has the parts, but they are rolling them out in a fashion they want to and not by what danger the parts are causing. They are not prioritizing vehicles that currently have no antilock brakes and are experiencing problems because of this part. I was hoping you could help intervene and convince Fiat Chrysler that vehicles experiencing an issue should be prioritized & parts be made available. I’ve been extremely patient, but driving such an expensive heavy duty vehicle with a recall being ignored is unacceptable. Thank you for anything you can do.
