Getting random ABS and traction control warning lights.
2018 Ram 3500 complaints
Owner reports filed with NHTSA about this vehicle, newest first and reproduced as filed. They are unverified accounts: one proves nothing, and a pattern across many is the thing worth reading. Back to the full 2018 record →
Abs electronic brake light issue,brakes spongy and feels like it’s lost braking power.
The contact owns a 2018 Ram 3500. The contact stated while driving 60 MPH, the vehicle unintendedly steered to the right. There was no warning light illuminated. The contacted turned the steering wheel between the 10 and 11 0’clock positions to keep the vehicle aligned. The contact stated that the failure persisted. The vehicle was taken to the dealer and was then towed to a local mechanic however, the vehicle was not repaired. The vehicle was not included in NHTSA Campaign Number: 19V021000 (Steering). The manufacturer was made aware of the failure. The approximate failure mileage was 102,000.
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
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.
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 Mo
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).
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
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.
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.
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.
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.
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
The ABS lights come on and off intermittently with a "service system" warning message
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.
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 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.
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
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.
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
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 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.

2018 Ram 3500 Laramie Longhorn, 64k miles, ABS/Traction lights on dash, intermittent, cancels cruise control and can't switch into 4WD. Dealer said it's a known issue and there is nothing they can do because there are no parts to order. I am a retired, disabled vet and I need help please. Thank You and God bless.
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!
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.
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?
Anti-lock brake system warning comes on the dash and the warning chime sounds. The warning dash lights come on and goes off 10-25 times in 1/2 hour of driving. There are no error codes stored in the computer system.
My 2018 Dodge Ram with 7175 miles on it has a continuous service anti lock brake and service electric brake light go on and off.Cruise control inoperable as it shuts off when the warning lights go on and off.Dealer did a $160.00 diagnostic on the system that I had to pay for only to tell me the hydraulic control unit needs to be replaced at a total cost of $825.00 that I am responsible for.Additionally,the part is “controlled” by the manufacturer and they are allotted one unit per week.No time frame when the vehicle will be repaired.This is a safety issue especially when the constant “chime “ goes off which is very distracting.I haul a camping trailer with this Ram 3500 duelly four door diesel four wheel drive and the braking is questionable.
The Hydraulic Control Unit has failed intermittantly. Complained to the dealer while it was under warranty and received 'cannot duplicate.' Dealer wants $1,000 to fix. This is a well-documented failing component.
The contact owns a 2018 Ram 3500. The contact stated while driving at an undisclosed speed, the electronic braking system warning light illuminated and chimed, causing the cruise control to become inoperable. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 15,000. The VIN was unavailable.
The contact owns a 2018 Ram 3500. The contact stated while driving approximately 30 MPH, the ABS warning light and the traction control warning light illuminated. Additionally, the message "ABS Disabled" was displayed. The contact stated that the failure recurred while driving. The vehicle was taken to an independent mechanic who retrieved DTC: C0020-01; and the mechanic determined that the ABS hydraulic pump needed to be replaced. The vehicle was not repaired. The local dealer and several unknown dealers were contacted and advised the contact that they could not accommodate the vehicle due to the size, and that the vehicle could not be serviced because it was not purchased at their location. Additionally, the contact had received notification of NHTSA Campaign Number: 21V398000 (Wheels); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the failure because the manufacturer customer care line was inoperable. The failure mileage was approximately 12,000. Parts distribution disconnect.
The Hydraulic control unit has failed. It has been taken to a mechanic and diagnosed. The electronic part has been replaced per my warranty info and mechanic recommendation and it is still failed, meaning the main HCU is the issue. The cruise control will shut off automatically and the ABS and traction control do not work while in fault. While towing a trailer up an on ramp, the HCU went into fault causing the traction control to fail and the pick up lost traction and started sliding sideways...Luckily I was able to get it under control without crashing. This was all due to the HCU intermittent failure, causing the traction control to stop working. While this is faulted, the ABS also does not work.
ABS sensor lights and sounds activate. Intermittant and irritating. Dealer says it is a well known defect and parts are not available.
My ABS and Traction Control components in my 2018 1-ton Ram are intermittently setting codes with the ECU, leading to loss of ABS, Traction Control, and inability to use my cruise control. I am concerned that I have a loss in braking performance without those components operating as designed. I have brought my truck to the local Ram dealer only to be told that the module will not be available for install until Feb of 2024 after an upgraded unit is made available to the dealers. I feel that this should be a recall, as a quick internet search shows multiple owners of the same vehicle are also affected.

Purchased this truck specifically to tow 14000 lb fifth wheel camper. Two months ago warning chime and “service electronic brake system, Service antilock brakes and Traction Control” caution lights repeatedly activate. I am concerned about towing in this condition if operating on rain slick roads and winter weather. Also the constant chime is a serious distraction. Truck is currently at the dealership for repair. 25000 on the odometer. Truck is out of warranty. These failed safety systems endanger mine and my family’s lives, as well as other motorist and the public.
Anti-Lock Braking system and Electronic Braking system, service system warning come on and off randomly all the time. Seems to happen when bumpy roads are encountered.
Antilock brake module and hydraulic control unit defects. Went for service at Kendall dodge in Soldotna Alaska and told brakes can’t be fixed due to defective parts.
ABS and Electric Brake System warning lights are on and off intermittently. These symptoms have been reported by many other owners due to defected part installation from the manufactor based on my internet research.
Anti-Lock Braking system and Electronic Braking system, service system warning come on and off randomly all the time. When this happens, cruise control does not work. Had it replaced at the dealership once and It started doing the same thing. Took it back and they said they didn’t know what was wrong with it And that they didn’t want me thinking they didn’t want to do warranty work. The warnings were coming on and off more frequent. Don’t know what to do. Do you have any suggestions? This is a safety concern for me.
My ABS light and Vehicle Stability Assist/Traction Control light came on. I now do not have the ability to use my cruise control. I believe the vehicle is unsafe.
Failure of abs system, traction control, and cruise control. Dealer has parts backordered for 4+ months. Throwing abs code for a bad Hcu or abs pump. Truck has zero abs ability.
Abs light traction control light come on and off while driving. Warning pops up which service electronic brake system

NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
