ABS and HCU Warning lights come on and off. Looking around the internet this is a huge Problem. Took it to a local Ram dealer today and was told its a $1600.00 out of pocket cost seeing the truck is just out of warranty (of course) with 37,000 miles on it. Driving with the cruise control on it throws the warning lights on and off and cruise stops working. It seems the brakes are weak too. The dealer also informed us today they could not even get the parts to fix the problem until at least August! We also had to pile another $1500.00 in it a few months ago because the 4wd did not work either.

The contact owns a 2018 Ram 3500. The contact stated while driving approximately 25 MPH, the "Check Brake System" and ABS warning lights were illuminated. The contact stated that the failure reoccurred intermittently while driving at various speeds. The vehicle was taken to a local dealer, where it was diagnosed that the Hydraulic Control Unit (HCU) needed to be replaced; however, the parts were on back order. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 57,000.
abs trac control going crazy dealer repaired under warranty about 15k drove approx 2k and same issue no longer under warranty tried to buy parts none available. truck doesn't start correctly when the lights are on and when driving there is a dinging as lights flash on and off.
Related to investigation PE 22-012, abs hyd control module failed truck only has 18,000 miles.
The ABS pump motor was replaced on 10/22/20 at 28,095 covered by warranty. The ABS/ ANTI SKID warning lights came back on at around 58,000 miles. The vehicle was taken to Firkins CDJR in Bradenton, FL for diagnoses confirmation and repair on 04/11/23. I was advised the ABS hydrolic control unit, part # 68143491-AA, needed to be replaced but was unavailable anywhere and it was not going to be available in the foreseeable future. Advised to call customer care who advised me to try a different dealership. I discovered that a replacement control unit, part # 68143491AB, is apparently available at Mopar parts for approximately $350. At this time I don't understand why a CDJR dealership says a part is unavailable that appears to be available on the internet. I pull a 5th wheel and at this time I apparently can't get the ABS system repaired in my 2018 RAM drw diesel with 59,000 miles on it. There was no incident or accident due to ABS system failure. Although the vehicle runs normal I consider this to be a potential safety risk.
The EVIC display showed Service Antilock Braking System and alternated to Service Electronic Brake System. It would constantly bing and display the ABS light and the Traction Control light. Unit failure of antilock braking system and traction control while driving. Problem is intermittent. Ram is aware of issue, but will not honor as warranty. Parts are BQ for months. Problem apprears to be wide spread.
I have two warning messages appearing on my dash. Service Electronic Braking System and Service ABS System. Took it to my dealership Michiana Chrysler Dodge Jeep Ram FIAT in Mishawaka Indiana. I was informed that it needed an HCU (hydraulic control unit) and that the part was unavailable because of engineering review until at least August 2023. The work order was closed and i was sent on my way and told to check back at a later date for availability. After a little reading i found that this issue is under investigation and i wanted add my truck to your list of reports.
Service electronic braking system ABS light. No parts readily available from dealerships 6-8 months for parts and still no contact on parts or a fix.
The contact owns a 2018 Ram 3500. The contact stated while towing a trailer full of horses, the traction control and the ABS warning lights illuminated. The vehicle was not drivable. The contact towed the vehicle to the local dealer, where it was diagnosed with needing the turbo and the ECU to be replaced. The vehicle was not repaired due to the parts not being available. The contact took the vehicle to another local dealer: Jacksonville Chrysler Dodge Jeep Ram Arlington (9600 Atlantic Blvd, Jacksonville, FL 32225: (877) 677-5782), where it was diagnosed with needing the turbo and the ECU to be replaced. The vehicle was not repaired due to parts not being available. The manufacturer had not been informed of the failure. The failure mileage was approximately 61,000.
Abs brake module problem over 8 months ago, replaced and same problem occurred soon after waiting on parts for several months, parts on back order. Dealer is well aware and also frustrated having several trucks with same issue. Since truck is used for towing heavy loads, Its a dangerous situation still having to use truck for towing, speed control and trailer brakes will not work when abs failure is flashing chimes all the time. Putting extended wear on truck brakes. I'm sure it against DOT rules and will fail my upcoming DOT inspection and not legally able to drive legally. Unfortunately I have another 2018 truck with same issues and this is the most frustrated I have ever been as a ram owner sine 1998.

My vehicle has under 18,000 miles. Driving down the road, the Service Antilock Brake System error light came on and also the Service Electronic Brake System light - they both started coming on and the bell to the light rang. It did this for the next 6 hours of driving (we were on a long trip) - I did research, and it appears to me, this is an ongoing issue with the 2018 RAM 3500 and people have been replacing parts and it does not go away. The next time I drove it, I had nothing going off. The next time I drove it, a few miles in, it started again. I took it to a RAM dealer, they had nothing on the code reader. Based on all the research I have done on line, it appears that this should be a recall item. I wanted to make you aware. We aren't what the exact fix is (without just randomly replacing parts) and we are not sure if the vehicle is safe to drive.
The ABS and traction control lights came on. The code reader reads C0020-01 Hydraulic contrl unit/ ABS Called several Ram dealers, they said this has been a problem with the Hydraulic control unit and should be a factory recall. I'm looking into having it repaired and it looks like the dealers are the only one that can clear the codeonce repaired and are the only ones who can bleed the brakes after the repair.
Rapid intermittent ABS warning light due to a diagnosed faulty ABS module. Module has been replace previously and now experienced second failure. Ram has no replacement parts available and now I am forced to drive with inoperable anti-lock brake system and a continuous warning chime.
ABS and traction control lights flash and ding on and off. Trouble shot it at dealership and wires were repaired hoping that would take care of it…. Nope, lights and dinging are back on. I tow a large gooseneck horse trailer up and down steep hills with sharp curves, across many state lines. We have the truck full of young children ready to show their horses - hence we have the crew cab. I’ll be towing within the month. I figure it must not be a safety issue - Parts are on back order until August??? We only have 40,000 miles on the truck. I can do without cruise control, but would like a safe braking vehicle - glad my husband got a stick shift to help control speed.
For the last 10000 miles of the total 53k on the truck, the ABS and electronic stability control lights turn on intermittently and the warning chime sounds. This sometimes continues for 1 mile, sometimes for 20 miles. Sometimes it will not happen for 50 miles. It appears to happen mostly on rough highways or city roads. Happens at 3 MPH and at 75 MPH. With ABS and ESC disconnected it is extremely hazardous towing my normal 16000 lb trailer, especially on wet or snowy roads. I have no other vehicle. If ABS is required on us highway vehicles for safety reasons, how can this not be a safety issue? If 2019-2022 ram 3500 trucks are under a recall for this same issue, why is 2018 not? Rawley cdjr in sierra vista az has verified the issue and recommended replacing the hcu and ABS module, but is not able to get the parts. They say possibly in august. They have offered to refund my payment for the parts they ordered and to disable the truly maddening constant warning chime to save my sanity. Then my truck will not have ABS or ESC or cruise control at any time. Is that safe? This same issue is well documented at the federal safety agency by many owners. It appears to be time to start complaining to our congressional reps.
The ABS system activates intermittently, causing random braking or unable to break. Took to the RAM dealership to be told the ABS hydraulic control unit 68143491AB needs to be replaced but it is on back order until August.
What component or system failed or malfunctioned? Intermittent failure of the electronic braking system. Audible Warning tone and indication ‘Service Electronic Braking System’ followed by ‘Service Antilock Braking System’ experienced intermittently. The multiple warnings automatically disabled the antilock brakes, stability control, and cruise control as well as producing annoying audible tone. How was your safety or the safety of others put at risk? I pull a Travel trailer loaded with our life's possessions and obviously my immediate family is with me. I cant trust or rely on my breaking system to stop my vehicle and trailer, Its a complete hazard to drive the vehicle on the road. Has the problem been reproduced or confirmed by a dealer or independent service center? I dropped my truck off today for a diagnostic to check the ABS issue and the dealer wants to charge me $199.00 + tax to verify this WELL KNOWN issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not at this time 3/20/23 Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no prior warning to the ABS failure, it simply started "dinging" and throwing the ABS failure warning on the IDC.
The contact owns a 2018 Ram 3500. The contact stated while driving at various speeds, the ABS and traction control warning lights were illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the ABS Hydraulic Control Unit (HCU) needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 23,000.
UNKNOWN - The ABS brake system warning light blinks on and off repeatedly. Then the warning will not occur for several days, but then starts blinking again. When this happens, the cruise control is abruptly disengaged. The code for this event is C0020-01(1/1)Active ABS Pump Motor Control-General Electrical Failure. I captured this with my own code reader as the event was occurring. When this event is occurring, the code clears itself after the warning light goes off and is not retained in the system for the dealer to see. The problem is chronic. It is the same problem that involved the federal safety agency for the 2019-2022 Ram 2500/3500 trucks. I have also read that there had been a class lawsuit. I simply want Ram to repair and correct this issue
Abs hcu warning can’t stop my 20,000 lb trailer. Slid off road in drizzle. No parts Chrysler is aware of problem
The ABS light is on and it has a code But dealer cant get the HCU part to fix it this is a common problem as i have researched this in the internet. I have had part on order for 11 months now. With the abs light on the cruise control and the trailer breaks will not work. The light comes on several times a day so working this truck is not possible. So i have a truck with 70,000 miles that i cant use but have to pay for. I see nothing for a recall and what good would it be when you cant get parts?????
Service Anti-lock brake and Service electronic braking errors come up on screen at random, sometimes the lights will stay one and cruise control is disabled. While braking they seem to shudder. Not safe for a Heavy duty truck that is able to tow 15k lbs.
