Service ABS light on dash comes in every few seconds while driving. When this happens cruise control shuts off and ABS system does not work. The issue started happening with about 45,000 miles on the truck.
Hi, The ABS System shows Service Antilock Brake System at the display, It comes and go so I assume that it is an intermittent issue, it does stays for hours or days and go on ad off during the whole drive, definitely is an issue. It allow the brakes to preventing locket when brake on certain circumstances. Had an issue on a wet pavement and have to handle to avoid crash with other vehicle cause the tires got locket and the truck slipped on the pavement for a considerable amount of feet's. Dealer inspected and replaced the module under warranty when I bought the truck and told me that it has to be replaced again.

Traction control, electronic braking system and ABS warning lights flash and ding repeatedly with a warning message to service ABS system and Electronic braking system. Dealer and local shop cannot obtain parts. I need a safe truck for work.
My ABS light keeps coming on and off intermittently causing my cruise control to be interrupted and causing vehicle to slow down unintended in traffic. doesn't stay on and only comes on and off when it feels like it. This is dangerous and could cause my brakes to not work properly or have someone hit me from behind when cruise control kicks off at high speeds on the highway. This should be recalled.
HCU and ABS module brake failure causing the ABS and traction control warning lights and audible tone to intermittently go off. This also results in the cruise control failing to work. This is the second time of such occurrence. First at 3 years old and 30k miles and second at 6 years old and 50.5k miles.
The anti-locking braking and traction control warning lights flicker along with a beeping. This causes the cruise control to also disengage. This first occurred when the 2018 truck was slightly over 3 years old and with 30,000 miles. I had both the HCU and ABS module replaced and it stopped the issue for a few years and 20,000 miles longer. At 50,500 miles, it has again become an issue.
ABS Hydraulic Control Unit intermittently malfunctioning while driving causing service ABS system warning to display and render ABS system along with Traction Control System and Stability Control inoperable. HCU electronic motor removed and internal inspection of brushes and motor components conducted. Inspection identified brushes sticking in guides causing intermittent contact with center shaft of motor. New HCU ordered 28 June 24.
Service ABS braking system keeps appearing intermittently along with traction control and ABS lights illuminating on instrument panel. NO RECALL for this problem has been issued and parts are expensive to replace. Please direct manufacturer to fix issue immediately. Thank you for your mission to ensure the safety of others!!
The Hydraulic Control Unit begins to malfunction presenting on the ECU as C0020-01 ABS Pump Motor Control-General Electrical Failure. This is fairly common in 4th generation 2500-3500 RAM trucks. The malfunction affects the ABS system, Traction Control system, and Adaptive Cruse Control system by deactivating them when the malfunction presents. This could cause the braking system and other systems to not perform in hard breaking/ emergency braking situations causing the operator to loose control of the vehicle. The Traction Control system and ABS system warning lights illuminate on the dash and the message of "service electronic braking system" is displayed on the HUD.
HCU for ABS has failed - Intermittently fails when in operation. Basically hit a bump in the road and it fails. Hit another bump and it "fixes itself". Then hit another bump and it fails. Lights up the ABS light, ESC light, brake light, esc. After some research, this seems to be a common issue on the 2018 Ram 2500's.
I have had the ABS system failure happen for the third time. the first was around 24000 miles about May of 2020, repaired at a Ram dealer in New Mexico, I believe they only replaced the ABS ECU. The second time was 43,298 miles [XXX] 2022, they replaced the HCU AT Walker Ram in Alexandria Louisiana. It has now failed again with 65,723 miles on [XXX]. Every time it has cause the truck to lose the Anti-lock braking ability, traction control, cruse control & ETC. I feel that Ram should do a recall and fix the issue with a upgraded parts that doesn't fail every 20k so miles and cause a safety risk.

The abs control module has gone bad. When you take it to the dealership ship to get fixed they can-??t order the replacement parts. The abs system is very important in heavy truck like these when it comes to drive on wet roads.The manufacturer should become responsible for making sure it get fixed and their is parts available to do so.
