The vehicle was purchased new Oct. 2017. On or about 1 Oct 2020 the vehicle had 19,100 miles. The vehicle displayed a constant "ABS Fault" / "Traction Control Fault". This was reported to my local dealer in Panama City, FL. The dealer service dept. worked the current Recalls and the ABS Fault at that time. Service was completed 10/16/2020. The vehicle was still under the basic 36M/36K mile warranty. The dealer reported the replaced part as MOPAR # 68143491AA, brake controller module. The vehicle is not in daily service, so the mileage is low for the age of the vehicle. On or about 1 June 2022, the vehicle had 22,250 miles when the ABS Fault resurfaced. At first it was intermittent, but later the ABS Fault / Traction Control Fault is constantly displayed. The brakes feel and appear to work normal, but I feel they would not work as intended during a hard braking or a skid or on wet pavement. I read dozens of owner blogs, Cummins forums, Ram owners forums, U-Tube, etc. It seems a large number of similar trucks are reported by their owners to have this problem. many owners like me have reported having this problem fixed by the dealer only to have it soon reappear. Many owners that have had this problem repaired also indicated the same part or part number and/or cite the trouble as brake hydraulic controller or a controller module.

ABS/ Traction Control lights constantly going on and off. Kicks off cruise control. Message blocks digital speedometer. Known issue, yet FCA will not recall.

Service Electronic Brake System came on while driving. Problem seems to be inconsistent and constantly turns on and off preventing ABS and traction control from working. Braking when the system is not working properly will result in massive feedback from the brake pedal.

See an article that abs failure issues are being reported on 2017-2018 ram 2500-3500. In the process of waiting for an abs hydraulic actuator. Loss of abs and braking

The brakes never have stopping power even with the exhaust brake. It take along time to stop at 30mph and if I'm going above 30 mph I'm afraid I will run into someone ahead of me if they put on their brakes.

Purchased truck used Fall 2021 with only 27k miles. After less than year and about 8k miles. ABS warning lights and sound randomly and erratically became an annoying problem. The cause is a defective Hydraulic Control Unit. Ram truck owners have posted hundreds if not thousands of complaints on the internet regarding this. Anyway, I had to disconnect the fuse for the ABS Module to prevent the annoying, interfering malfunction. The truck brakes safely but there is not the additional safety of the ABS system. The newer version of the Hydraulic Control Unit is not available and backordered until at least the end of January, 2023. Dodge Ram owners of these trucks can't even pay high dealer repair prices because no one has the part. I believe 2019 and newer models have the same problem but Ram has issued a recall for those model years.

Completed a hard stop, but ABS system did not appear to work correctly. Once stop was completed, had two malfunction lamps and a "service ABS warning". Lights and warning went away once I resumed driving. In a separate incident, I took off from a stop in wet conditions and the traction control system did not appear to be working, vehicle spun the rear tires an abnormal amount. Once this happened, the warning lights and error message returned, but went away upon further driving. I visited the dealer and had them pull the error code and it was "C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE". There is an active technical bulletin stating the issue is with the hydraulic control unit (HCU). It appears to me that this problem disables the antilock brakes as well as the traction control system. The danger here is that the warning lamps and error messages go away, leading one to believe the system is functioning normal when in fact it is not. I was advised by the dealer that the replacement part is unavailable and could be for several months.

ABS/traction control intermediately functioned for several weeks. But is now inoperable.

The brake warning light flashed on and off irregularly. Took to the dealer but was told they couldn't diagnose it since the light was currently off. Months later the light was on when I took it for the annual State safety inspection. Diagnosed the hydraulic control unit needed to be replaced. It took them a few weeks to get one in but it was finally completed at a cost to me of a little more than $1,000. The service writer told me that they have found this to be a common problem in low mileage Ram 2500s. Currently I have approximately 17,000 miles on my 2500

Service Electronic Brake System and service Antilock Brake system light come on and off intermittently at random times. Some time on and off a few times faster then it can display the message. The Hydraulic Control Unit was replace one already. Reading online there are several 2017 and 2018 rams having this issue.

The ABS control module and the HCU has Failed twice on this truck resulting in loss of traction control, ABS and cruise control. The unit was replaced around 42,000 miles and then failed again at roughly 60,000 miles. Ram will not replace under warranty. the failure causes the abs and traction control light on the dash to come on and off constantly. it also shuts down cruise control. I believe it also causes excessive ware on the rear tires due to the traction control system not working properly. This is a major problem and judging by online repair forums there are many other people experiencing the same issues

- Casselberry, FL, USA

This issue was repaired by the dealer one year ago and it has happened again, they tried to charge me by pretending they didnt know about the previous repair. the internet is full with the exact same complaint and how is this not a recall to hold them accountable"? the service electronic brake system and ABS lights come on and off each time making annoying noises. when the lights are on the 4x4, cruise control and other items will not engage. the dealer agreed to repair it but told me to call in 5 months to see IFFFF any parts are available this not only shows its a wide spread problem but their incompetency to fix it. how do I know the second module they replace wont malfunction as well??"

- Miramar, FL, USA

Under normal driving conditions I got the -??SERVICE ANTILOCK BRAKE SYSTEM-?? message along with an ABS light, traction control light, loss of traction control, loss of cruise control functions and loss of 4x4 functions. This is a well known safety issue that needs to be addressed by the manufacturer. With ABS being a SAFETY feature required on all vehicles, it is only appropriate that this become a safety recall.
