At 26075 miles 9/10/2020, got error saying service electronic braking system. Dealer diagnosis code C0020-1was HCU (hydraulic control unit) failed; replaced unit part number 68143491AA. Problem solved. At 34412 miles 5/31/22, got same error stating to service electronic braking system. Dealer diagnosed code C0020-1, HCU failed. They replaced part number 68143491AA, again problem solved. At 40,125 miles, 8/30/2023 same error message. I will be taking to dealer, but parts are not available until February 2024 or later. When this unit fails, ABS is disabled, as well as trailer braking and cruise control. This creates a serious danger as the truck is capable of towing a load in excess of 17000 lbs. using the same part that appears to have an issue is not the solution.

HCU failure at 75k miles causing loss of ABS, Traction Control, and cruise control functions brakes are not as efficient anymore part is 8-12month back order, fiat Chrysler dealership locally said nothing we can do don't drive it wait for $700 part to come In some time in the future. Only vechicle I have I. Self employed can not just park truck for 8-12 months and continue to make payments, there is no option to sell as someone will not buy with abs issues and traction control in-op. This is a wide know issue on rams fiat Chrysler has done nothing to ensure the safety of its drivers and owners. For them to simply say park it do not drive wait 8-12 months to be fixed is absolutely ridclious. A reca needs to be issued and part failures need to be handled. Quick search on line shows many trucks having same problem and same results at dealership.
ABS/HCU intermittent failure resulting in loss of traction control, ABS function, cruise control. The risk associated to myself and others is the loss of ABS and traction control, in bad weather (rain, snow sleet) conditions the drivability of the vehicle is severely compromised. I was made aware of the open class action suite regarding this flaw and have not left the truck for dealer service. Warning lights include ABS, traction control, and service electronic breaking.
ABS Light and Traction Control Light are both on. Loss of ABS functionality. The code displayed is C0020-01. The dealer has not looked at this vehicle yet but service will be scheduled with them.
ABS error code on truck approximately April 2023. Had tested at Dodge dealership in Marshall where they determined it was the ABS controller that was bad and had to be replaced. They informed me that this would not be available until August of 2023. This would mean that my anti lock braking system would not function properly for several months. I contacted two other Dodge dealerships in East Texas as well as an independent diesel mechanic who confirmed the same thing - this part would not be available until August 2023. I had Marshall dealership to put my name on list with others who had the same issue, and I had to continue driving the vehicle with the ABS system compromised, with the awareness and care knowing that this is a safety concern. August 2023, had not heard back from the dealership so I called and asked about the ABS controller issue. They told me they had been notified by Dodge that this part is not available in August and they had no expected date for it to be manufactured and available for these repairs. I Confirmed with other dealerships and two independent diesel mechanics. It is now mid September and I am having to continue driving with safety compromised due to the bad ABS controller and Dodge not doing anything to address this situation for me or what I understand are several others. No doubt, if they have not already happened, there will be accidents due to the extended time of ABS malfunction on RAM trucks. I am now reaching out to the federal safety agency as the urging of one of the independent diesel mechanics. I appreciate your time and attention and anything you can do to help Dodge address this widespread safety concern as soon as possible.
Abs and traction control lights are on. Cruise control will not work when lights are on. Lights go on and off with chime very annoying. Brakes will not function properly when lights are on. Contacted dealer no eta on parts. Almost 2 years now. Contacted dealer before warranty was out. Next time I went to ask I got another service rep and he said my warranty is out. This is not good.
Abs light service system
ABS LIGHTS COMES ON ANTI SWERVE LIGHTS COME ON HCU MODULE FOR ABS SYSTEM BAD THESE ISSUES ARE NATIONWIDE IN RAM TRUCKS ..parts are hard to get . Dodge should recall I’m paying out of my pocket.
I am getting a warning on this dash telling me that I need to "service electronic braking system". When this message comes up I lose my ABS brakes, cruise control and I get a traction control warning light. Sometimes this will stay on for weeks and then go off for a day and start all over again. When the road is wet you have to be careful with the brakes. I went to the local dealer in Bryan, TX and showed him the warning lights and he told me that I had a bad sensor in the truck. The cost could be as high as $1500.00. The dealership told me that they repair on an average (2) two trucks a DAY foy this PROBLEM. I had the truck checked for any codes in the system and the tech told me that I did not have any codes but yet the tech could see both warning lights on my dash. ABS light and Traction control light.
Intermittent Anti Lock braking system failure messages. From my understanding this is a very widespread engineering/ components failure. This is a huge safety issue and a recall needs to be issues. RAM was allowed to build trucks for years that had major steering issues, now the brakes don’t work properly. the federal safety agency needs to hold them accountable.
When operating the vehicle the Service ABS/Traction control light starts flashing and cruise control becomes disabled while driving. ABS and traction control becomes disabled. Safety issue! Advised the part will not be available until Feb 2024 and to operate vehicle as is.
What component or system failed or malfunctioned, and is it available for inspection upon request? On July 28, 2023, while travelling Northbound on Hwy 287 N, the engine brake automatically engaged without depressing the brake pedal or decelerating. Prior to this, there was no indication of any problem. No messages or warning lights appeared. I notified Karl Klement Dodge in Decatur Texas to inquire about braking problems or recalls affecting this model. I was told that I had no recalls, and they were unaware of any similar issues. On 9/11/23, after travelling approximately six miles, the ABS and traction control yellow warning indicator light illuminated and an audible warning ding initiated. These warning lights came on and off at recurring intervals, on multiple occasions. Eventually, the service ABS system warning initiated on the center control panel. At this point, I had driven no further than 8 miles. I proceeded to an independent service center in Bridgeport, Texas and spoke with a certified mechanic. He did a computerized diagnostic which indicated the HCU/ABS Module system was showing to be defective. The mechanic stated that they have had to replace this item on other vehicles recently. I again notified the Karl Klement Dodge dealership to inquire about my warranty or a recall or any other problems relating to the ABS or other braking system components. I was told that it would not be covered under warranty, and that there were no problems with the braking system on the particular model, nor recalls but that I could, "bring it in if [I] want to." The current mileage on this vehicle is only 24,314 miles as of 9/11/23. Due to the safety necessity of the braking system, it is a severe safety concern. Upon further research, I have found multiple parties with similar problems with the ABS system on this model.
ABS and Traction Control lights intermittently comes on and then will go off after a few minutes and "service electronic braking system" message appears. This may happen 25 times in a 5 mile trip and the next day not do it on a 30 mile trip. DTC C0020-01. Safety issue since ABS not working correctly and parts are very difficult to find. This is an on going problem, not a one time occurrence.
Antilock brakes Malfunctioning dealer Says Wont fix it under extended warranty Does Not allow antilock brakes to function properly

I try not to drive truck at all even dealer says to drive it with no ABS or traction control.
The "Service ABS" warning light randomly started coming on in the dashboard display. Sometimes it alerts every few seconds, other times it may not alert for days. When this happens I experience a loss of anti-lock brakes, traction control, and cruise control. This truck is used to pull heavy loads and the random loss of anti-lock brakes is not good. My local dealer says that parts are on on back order for many months. The potential loss of braking is scares me and is a danger to others around me. Yes, the vehicle is available for inspection.
ABS module has been replaced 2 times after factory modules have failed. I now have a 3rd failure and Ram says unit is under engineering review. 82,000 miles on truck.
Abs light on repaired under warranty once now back on again truck only has 20000 miles but out of warranty light has been on for about 3 months dealer said no parts till 2024 dodge is changing the parts to fix this is what they are saying so they new original parts replaced with new but same parts was not fixing problem they should issue a recall it is totally their fault
Auto brake anti skid components failing creating unsafe brake operation while towing a 15,000 lb trailer. Dealer states parts won't be available for at least 18 months. This is a hard fault and can't be reset.Dealer states this is a high failure item on these trucks.
The Hydraulic Control Unit Chrysler part number 68143491AA failed and been replaced multiply times on my vehicle. I have the current failed part available for inspection upon request. 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 problem has been reproduced by my local dealer twice both with the original part and its' replacements. The vehicle/component has not been inspected by the manufacturer, police, insurance representatives or others. There were no Warning lamps/messaged before failure only after. These would be ABS lamp and traction control lamp plus a service ABS warning message.
The service ABS braking system warning flashes on with a chime frequently when driving. This started 3 weeks ago. According to the Ram Forums this is a common problem with 2018 trucks. My truck is a 2018 with 352623 miles on it and according to the Dick Hannah dealership a part that is out of warranty. There is no replacement part since the original inventory was all pulled back from the dealerships to the manufacturer due to the incidences of failure. This information was given to me by the Dick Hannah parts manager. He said a newer more reliable version of the brake module is being built but replacements are not expected for at least 4 months. Ram knows the part is and was defective, i am out of warranty and have a dangerous truck to drive for the next 4 to 5 months then a estimated $1500 repair bill. I want Ram to pay for this and to expedite the replacement parts and the federal safety agency to do their job and serve us the consumer instead of the manufacturer. I am seeking legal recourse too. I attached the repair code report derived from my Blue Driver code reader tool.
ABS failed during a panic stop causing the vehicle to skid. Received a notice on the dash to “Service Electronic Braking System” followed by the ABS and traction control lights coming on then off a number of times. It is my understanding that the Hydraulic Control Unit has failed, and FCA is aware of this issue. Failure of ABS in a large heavy pickup truck is dangerous, and FCA should issue a recall to repair the affected units.
The contact owns a 2018 Ram 3500. The contact stated that while driving at an undisclosed speed, the ABS and traction control warning lights were illuminated. Additionally, the Service ABS and Service Brake Assist messages were displayed. The vehicle was taken to the dealer, where it was diagnosed that the hydraulic control unit needed to be replaced; however, the replacement part was on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 64,826.
The contact owns a 2018 Ram 3500. The contact stated that the ABS and brake warning lights was flashing on the instrument panel while driving at various speeds. The vehicle was taken to a dealer where a diagnostic test was performed; the diagnostic showed a faulty computer module had caused the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 44,000.
The code C0020-01 ABS Pump Motor Control - General Electrical Failure popped up. This happened with 53172 miles on the odometer. Looking on the Cummins Forum, this happens often to the 2017 and 2018 Ram 2500 and 3500 pickups.
I purchased my 2018 Ram 3500 new, in July of 2019. Since then, the HCU/ABS Module has failed 3 times. The first occurrence was at 4391 miles, the second was at 24768 miles, and the third, was yesterday at approx. 45000 miles. The "Service ABS System" light goes on and off intermittingly, which shuts down cruise control and other electrical components. The brake pedal at times feels stiff when brakes applied. This repair is close to two thousand dollars. I've read the other complaints while researching this issue. Something needs to be done by RAM to correct this safety, and excessive cost to owner issue.
Anti lock brake service light came on repeatedly and vehicle was taken to South County Ram dealer in St. Louis and they scheduled a service appt in July 2022 and they indicated an antilock module was required and did not have part due to manufacturer and did not know when part would be available. The vehicle again was taken to same dealer on July 10, 2023, and same story. This was reported to Chrysler Complaint line that same day and no response from manufacturer. How can an important safety part not be available? How can they continue to produce vehicles and not have replacement safety parts?
The contact owns a 2018 Ram 3500. The contact stated that while driving at an undisclosed speed, the ABS warning light illuminated, and the cruise control became inoperable. The vehicle was taken to the dealer and the contact was informed that an unknown sensor needed to be replaced; however, the part was not available. The manufacturer was made aware of the failure. The failure mileage was approximately 20,000.
When driving at Interstate speed of 65 MPH pulling my goose neck horse trailer the instrument panel started dinging and indicated "Service Electronic Brake System", "Service Antilock Brake System" and the Cruise Control stopped working. I slowed and continued home with warring alternation with "dings" every few seconds. I took vehicle to local Dodge Dealer (Blaise Alexander Lewisburg PA) on 08/10/23 who checked the truck and said I needed the HCU replaced. (Code: 0020-01) I had to wait a few days to get the part. Truck was returned to me on 08/15.23. Invoice Number CHCS26809. Total Cost: $843.75
