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 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

- Rushville, NY, USA

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

- Warrenville, SC, USA

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 NHTSA, 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.

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!

- Statesboro, GA, USA

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.
