From what I understand these Ram Pickups have numerous problems with the ABS module and HCU unit going out and our truck has had the same problem we had to replace the HCU unit at only 10876 miles on November 4. 2020 and now we have had the ABS warning lights coming on and took to dealer on 10/11/23 with only 22287 miles and they say we need a ABS module, we are told this part 68347098AB is on back order and as of January we still have not received it and now dealer is telling us they came out with new part number. For ram not to be able to provide parts to fix their defective braking system parts is a safety issue and Ram should make this an urgent recall issue and pay for the replacement. You cannot find the part anywhere and Ram Truck owners are having to drive with dinging warning lights and unsafe braking issues.

While driving the ABS and traction control warning flashes and dings with every small bump that is hit. Confirmed HCU unit by stans garage in Duncanville tx
The Anti-Lock Brake & Electronic Braking System error caused the internal Trailer Brake system to shut off trailer brakes just like it shuts off the cruise control when warnings come up on the dashboard. The incident happened Aug 28, 2023 while following my son and my wife in a vehicle ahead of me. I had to change lanes to try to avoid something that suddenly came across in front of my vehicle. I applied the brakes and then the trailer acted like it didn't have any brakes fell over & was totaled. If this was in traffic someone could have been killed. The "Check Anti-Lock Brake System" & "Check Electronic Brake System" warnings started coming up intermittently as I drove my RAM 3500 Diesel truck starting sometime around July 2023. I drove to the local RAM dealer and told them about the problem. They acted like they had never heard of this problem and proceeded to check the error code and then stated they had never heard of this error before. They said they would check with RAM engineering on what needed to be done. They then said there were other similar RAM trucks with the same issue & that the parts were on back order. I finally got an appointment for the dealer to check my truck after sending an email to the Service Supervisor. After they checked my truck on August 16, 2023 they said that my truck needed a new Anti-Lock Brake Control Module. I had seen that many others on the internet blogs had stated that both the Anti-Lock Brake Control Module and the Hydraulic Control Module (HCM) needed to be replaced. I was then told by the service person that the Anti-Lock Brake Control Module would not be available for months (until sometime in December) and the Hydraulic Control Module (HCU) had no date of availability. They also checked with the RAM technicians at the dealership about safety driving the truck and towing a trailer until the part came in. They told me that only the Anti-Lock Brakes may not work so it would be safe to continue to drive it and tow a trailer.
Service Electronic Brake System Warning. This warning started coming on sporadically. When the warning appears in my dash, I will lose abs function, traction control, and cruise control. This appears to be a common problem with this year Ram truck. The fix is an abs module, and or, a hcu module.
In September 2023 I started getting a warning to service the ABS system. The warning and associated annoying tone would appear and than disappear at different times. I spoke with the service manager from Lithia Dodge where I purchased the truck. He told me that he was unable to service my truck because the ABS parts are not available. I was told that like a great number of Ram truck owners, I had to "hurry up and wait for a solution." This is unacceptable. To make matters worse, I am moving out of the country in February. I had a buyer for my truck and now it is un-sellable due to this ABS issue. I hope that a re-call will be issued soon so those of us with this common issue can get some relief. Thank you
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.
ABS and Traction Control lights on, beeping, Check Engine Light On, Codes U1408-00, C0020-01, C0044-28, P203F. Messages -Service Electronic Braking System, Service ABS Braking System, Service Trailer Brake System. My Safety As Well As My Passengers Safety is At Risk Because Apparently My Brakes Dont Work Properly.
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 and Traction control light turn on and off constantly
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.
The ABS lights come on and off intermittently with a "service system" warning message
Service ABS brake system and Service Electronc braking system warnings constantly come on and affects braking system and cruise control. Dealers have no answers, Dodge has no answers. As a commercial vehicle driver if my abs doesn’t work properly then I’m shut down, but dodge can get away with this in a regular vehicle. This is a very very common problem with 2018 dodge 3500’s and any help to get this fixed would be greatly appreciated, because they have no fix to the problem.
ABS and Traction Control lights turn on and off while driving
I have a 2018 Ram 3500 with the Cummins 6.7 diesel engine. My ABS traction control lights constantly kick on and off. This is unknown problem as the ABS module needs to be replaced. Ram knows about the issue as thousands of trucks are affected, there is no recall. There are no parts available according to my dealer. When the lights kick on, I have no antilock brakes, no traction control and four-wheel-drive will not work. I live in the northeast, so not only is this dangerous on wet roads, but my truck is useless in the snow, as four-wheel-drive will not work. A recall is needed to force ram to produce these parts and fix the trucks at their cost
I have an active issue with the hydraulic system that presents by the ABS and Traction Control lights toggling on and off repeatedly. I pulled the ABS codes as did an independent repair shop and got code C0020-01 ABS Pump Motor Control - General Electrical Failure. There appears to be a service bulletin regarding this issue. It has not been repaired/replaced at this time.
ABS/Traction control lights and failures of the HCU and/or ABS control module. Warning lights constantly going off at about 25k miles, fixed under warranty. I think they replaced the HCU and control module in about 2020-21, but not sure. The lights continually flash again (starting at about 50K miles) and I'm assuming another HCU failure, but it's out of warranty and was told by dealer a year ago that it would be a expensive fix at my expense, and that they would have the truck for a while and may not be able to get parts. I was told that after getting it fixed, they could see if it would be eligible for any coverage, but their work was only guaranteed for 10k miles. I've researched it and discovered the original part was replaced by another part number, although the new part seems to fail as often, and it's usually the HCU and/or electric motor on HCU. I tried reporting this before, but got no confirmation or follow up from manufacturer of the federal safety agency, so I'm not sure it went thru. Truck currently has about 63k miles.
ABS failure occurs at multiple speeds and times. This occurs during normal driving conditions as well as while towing. Have reported to local dealership as well as brought in for service. Informed ABS and Pump unit needs to be replaced. Has been over 1 year and still waiting on RAM to fix. This is a safety hazard
The Hydraulic Control Unit Chrysler part number 68143491AA failed and was replaced on my vehicle. I had the vehicle back to the dealer numerous times before they replaced this item. 14000 miles later the same problems are happening again. This causes the Anti-lock braking system and Traction control system to no longer function limiting function under wet or slippery conditions. This puts the driver and others at risk. The vehicle/component has not been inspected by the manufacturer, police, insurance representatives or others. The warning lamps and messages will flicker on and off repeatedly and randomly while driving.
ABS system failure. Also disabling 4x4 wd during winter driving over a snowy pass; no abs, no traction control, no 4wd, no warning. I spun out several times and nearly crashed on my way home. Come to find out thousands of truck owners of this model are experiencing the same problem. This is a threat to public safety. Please address immediately
ABS warning indicator occurs intermittently. Dealer indicates fault code C0020-01 - ABS Pump Motor Control General Electrical Failure. Found active FCA STAR Online Publication 'case number [XXX] dated 4/28/2020 that indicated this failure, with instructions on troubleshooting/repair, and instructions for returning parts to FCA. [XXX] Dealer (8/28/23) had informed me that parts are on on backorder, unavailable, and could not be ordered until spring of 2024. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Service electronic brake system, & service hydraulic brake system warning lights intermittently display on dash. Disables both of those safety features as well as cruise control. These are very important safety features especially when hauling a load!
ABS and traction control warning lights intermittently come on. Has been repaired twice by local dealership by replacing the two computer modules/pumps responsible for ABS system. Cruise control disengages when this happens. When this happens at highway speeds while pulling a heavy trailer in traffic it's a very dangerous situation and needs to be corrected by manufacturer.
My ABS/Traction Control light has been coming on for over 2 months. There seems to be no pattern to when it happens. Someone pulled out in front of me yesterday and I barely missed them. I understand the problem part is in short supply. I tow a heavy fifth wheel camper. I need to get this fixed!
Antilock brake and electronic brake modules are having electrical failures
I purchased my Ram 3500 new, in 2018, at Nucar auto dealership in Tilton, New Hampshire. When I reached approximately 24,000 miles, my "Check ABS" and "Check Traction Control" lights activated on my dashboard and the message console. I was using cruise control at the time, which immediately deactivated. This could have caused an accident if I had been slower to react. The warning/failure was intermittent at first, but over the next few days became almost constant. The lights/warning would flash, the warning bell would ring, and then shut off for a minute. Over, and over, and over. I brought the truck to the dealer and they ran a diagnostic. They diagnosed the following: C0020-01 - ABS Pump Motor Control-General Electrical failure INTERNAL HCU OR ABS MODULE FAULT. WILL NEED TO REPLACE HCU AND RETEST The truck only had 24k miles on it, but since it was past the 3-year warranty period, they quoted a cost of almost $1,000 to do the repair, not counting the $155 they charged to run the diag. They also stated that the parts were on backorder, and wouldn't be available for some time. Since then, I have driven the truck as little as possible since it is a safety issue. Based on information in online forums, I know that this is a problem in thousands of 2017-2018 Ram 2500&3500 trucks. My next step is to join one of the several existing class-action lawsuits, create a new class-action suit for New Hampshire, or file an individual suit. Will Ram issue a recall for this?
