    The HCU failed twice under warranty illuminating the ABS and TRAC lights disabling ABS functions (obviously fixed by a dealership). This is a safety hazard trying to stop a RAM 3500 without ABS, this in poor weather is beyond UNSAFE. Now, it has failed again not under warranty, same issue, same part. That is four units that have failed in my truck with only 27,000 miles in five years. The brushes in the electric motor start to fail so the ABS/TRAC light will flicker when hitting bumps, or in cold weather. The finally, they stay illuminated disabling crucial brake components and safety systems. I can have my vehicle looked at if necessary, I plan on replacing the HCU myself when the part arrives in a week (I work for a dealership).

    Abs light/ warning goes off and on continuously. Brought truck in to repair and was told that they aren’t making the parts to repair this known issue on many vehicles. Was told parts available In February which has now been changed to April. This is not acceptable. Along with being very annoying with warning light flashing off and on. It’s also unsafe. As the ABS and traction control are affected by this.

    Part: 68143491AB The abs, traction control, hydraulic fails. The part begain to fail around Dec of 2022. Progressively has gotten worse. Ram dealership cannot fix or replace. Warning light and chime is off and on roughly 10 times a minute. Pressing on brakes off and on will randomly fix and reproduce the problem.

    Dealing with intermittent service brake system messages for over a year now. Light is constant now which means my ABS / anti skid/ and cruise control no longer function. Believe this is the ongoing HCU / ABS module known issue. Frustrating going into the winter months with such a heavy vehicle and loss of safety feature with no fix from Ram.

    Traction control and abs lights have been coming on randomly while driving over the past several years. Seems worse and more frequent in cold temperatures. Scanner reads code C0020. Cruise control suddenly shuts off when this happens causing a safety hazard especially to those traveling behind. Dash lights and constant chimes are very distracting while driving. No abs makes winter driving more dangerous as well. Seems to be a common problem with this vehicle. There should be a recall issued to fix this.

    ABS LIGHT AND TRACTION CONTROL LIGHT WOULD COME ON AND OFF. Recently both lights stay on all the time and on the truck display it reads service electronic brake system.

    My ABS electronic brake system warning came on indicating I need to have the electronic brake system serviced. I took the truck to the dealer and was told I need a new ABS control module. I was told the part was not available and they had no ETA for the part. I have been without my ABS brakes for six months. I tried calling the manufacturer and got nowhere. This has affected my cruise control and anti skid control. I tow a trailer and feel I am driving an unsafe truck.

    ABS light comes on needs a hydraulic control module which has been on back order for over a year. These trucks will lock up the brakes and lose traction without this part.
