The contact owns a 2018 Ram 2500. The contact stated while driving at various speeds, the ABS and traction control warning lights illuminated with an audible chime. The contact stated that the brakes would slip upon depression of the brake pedal while the warning lights were illuminated. The vehicle was taken to the dealer and the mechanic linked the cause of failure to the HCU (Hydraulic Control Module); however, the parts for the repair were on back order. The manufacturer was notified of the failure and referred him to the federal safety agency hotline for assistance. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 75,500. The VIN was not available.
My truck at 38,000 miles started flashing occasionally ABS and traction control warning lights. Neither my ABS or traction control are working when the lights are on. Now I have 45,000 miles on my truck and both lights are on all the time I had the code read and it is C0020-1. My understanding is this is a known problem and my cost is over $1000.00 to fix this problem. I contacted my dealer and they told me my truck is out of warranty and they don’t know of any recalls or investigations into 2018 Ram 2500 braking systems. I have not gotten the issue fixed and we drive it as little as possible. The truck is available for inspection. I am not willing to pay the dealer to inspect the truck.
At approximately 104,000 miles beginning last September I started intermittently receiving a warning service abs brake system and traction control. It would be more frequent when going down a bumpy road. It continued for a long time and gradually became more constant. Internet searches had suggested fixes of removing the fuse for the abs system, in and of its self creating another safety problem. Ram has issued a bulletin for its mechanics telling them to change the ABS control, so obviously this happens a lot. The invoice for the repair is a attached which says there was an internal short on the abs pump. I note that beginning in 2019 Rams there is recall for a faulty abs pump. Obviously the pump on my truck is also faulty and should be replaced a Ram's cost by a recall. I will attach the invoice if there is a place to do so in this form. Lots of complaints about this issue can be found on line. Some examples are at: https://m.carcomplaints.com/Ram/2500/2018/brakes/service_brakes.shtml and https://www.ramforum.com/threads/2018-ram-4x4-diesel-service-anti-lock-brake-system.153111/page-4
The antilock brake system has failed. The vehicle is available for inspection. Without the antilock brakes operating properly, the vehicle is harder to control in emergency situations or on slippery surfaces, endangering the safety of myself and others. The problem has been confirmed by an independent service center. ABS and traction control lights are on. Service ABS Brake System message on dash. ABS and cruise control inoperative. Code C0020-01 present. Symptoms first appeared May 17 2022.
•ABS control module/traction control is intermittently failing •no antilock braking or traction on wet/icy conditions •yes, both dealer and a second opinion garage have both diagnosed the problem •only the garage mechanic inspected the failing part •vehicle warning lights come on when part is failing
Truck was bought by me 12/28/22 with around 4900 miles on it. Within driving the vehicle approximately 40 miles the service electronic brakes and service abs lights began to illuminate intermittently. I have driven approximately 2000 miles and they keep going on and off, seemingly while hitting bumps. From my research I believe it to be a failure of the abs hydraulic control unit. I believe the manufacturer knows this to be a common problem and has revised the part in question. This should be a recall on these particular trucks, a quick Google search of the part number of the hcu will reveal numerous people with the exact same issue.
The contact owns a 2018 Ram 2500. The contact stated while driving 40 MPH, the ABS, cruise control, and traction control warning lights illuminated. The vehicle was taken to the dealer to be diagnosed. The contact was informed that the brake control valve needed to be replaced. The vehicle was repaired but the failure recurred. The manufacturer was contacted and notified of the failure. The contact was referred to the federal safety agency Hotline for assistance. The failure mileage was 14,000.
The ABS module and associated control unit have failed. This causes the anti lock braking and traction control systems to be inoperable which can cause the vehicle to lose control which can cause injury or death. FCA is aware that these units are defective and refuses to fix them.
C0020-01 code began coming in and out immediatly following a service at my local Ram dealer. I returned to the dealer after the warning lamps and messages all came in around ten times within a mile of picking my truck up from them. The dealer used a device to clear the messages, but the alarms returned again after I left. There are multiple warning lamps and messages that remain in as a result of this: service anti-lock braking system, ABS warning lamp, traction control lamp, and a loss of cruise control functionality. While the constant "dinging" sound and loss of cruise control on a truck with less than 20K miles is disappointing, I am concerned whether or not these warnings are indication of a serious safety hazard to my family and/or those we are on the highway with. My truck is available for inspection. The issue was confirmed by my local dealer who cleared the alarms when they first came in.
Abs and traction control lights come on and off dealership replaced the hcu and the problem stopped. 2 years later and only 3,000 problem started again. Contacted the dealership and they said its a known issue but no parts are available and no recall
Traction Control Light is illuminated, Service Trailer Braking System, and Service Trailer Brake System Notifications are present on engine startup. ABS system appears to be inoperative in slippery conditions. Service Engine Light comes on every 15 miles or so with Codes P0572 and P0572pd. Download codes and they go away.
Slightly out of warranty. Suddenly starting getting ABS warning light coming on and warning chime then it goes out and shortly thereafter comes on again, it doesn't quit for many miles. Take to dealer and find out its a failed ABS module and HCU. Also find out through repair history that the ABS module had been replaced at about 14000 miles so this was a second failure. Found out through online sources that there are many failures of these items on but it is mostly on the 2018 vehicles

The contact owns a 2018 Ram 2500. The contact stated that while operating the vehicle, the ABS module message was displayed. The vehicle was taken to the local dealer who diagnosed that the ABS module was faulty and needed to be replaced. The ABS module was replaced, and the failure was remedied; however, the failure reoccurred. The manufacturer was not yet notified of the failure. The contact referenced the federal safety agency Investigation: PE22012 (Service Brakes, Hydraulic). The contact indicated that the vehicle had experienced the same failure listed in the investigation. The failure mileage was 50,000.
inconsistent flickering/flashing of the "service electronic brake system" & "traction control unavailable" lights with audibles dings. Additionally, the ABS light illuminates. After research this appears to be a common failure point that costs over $1,000. My truck is a 2018 with 36,000 miles. I do not know if my brake system will fail on me or what. I haul a 12,000 lb trailer with horses and rely heavily on my ABS system working in case of emergency. I'm submitting this claim because I know there is an open investigation by the federal safety agency and would like to add on to the complaints.
Multiple failures on ABS Brake control module. Module has failed twice now within 30,000 miles. Manufacturer has no urgency in prdocing replacement parts. Cannot drive vehicle due to this issue.
ABS and traction control light are coming on and going off intermittently, when it comes in shuts off cruise and could lead to a rear end hit, after searching for ABS issues seen Ram was recalling a lot of vehicles for an ABS issues, was wondering why the 18 year was not included?
ABS and Traction control lights on together, took into ram service dept which indicated internal fault with ABS pump (hydraulic control unit) need to replace and bleed brakes to correct. Not possible to order needed ABS pump replacement until at least 2 months away, advised not to use vehicle especially for towing as unsafe in this condition.
ABS system failed to perform. Hard braking on interstate caused tires to lock up and vehicle began to slide, causing trailer to start to outrun truck. A message appeared stating that ABS system needed service. The message is not stored in the message center so I can not confirm wording. Dealership replaced a brake component due to finding a problem buried in the computer at 39993 miles. This event occurred at approximately 45000 miles as the truck now sits with 45057 miles. Appointment has been made with dealership which states that diagnostic fees may be charged.
Flashing abs and traction control no cruise control Code C0020-02
Abs, stability control and cruise control are not working as they should. Dash is constantly displaying a warning error about the brakes and stability control.
Anti lock brakes are on and no towing brakes. Replaced hydraulic control unit and ABS control module. Message showing service anti lock and ABS. Dash continually ding to service. Unable to reset.
During the month of July 2021 I would get a message to service the antilock brakes. At 16400 miles I took the truck to the dealer any they replaced the Control Anti-lock brake system and Module. Part numbers 68143491AA & 68347098AB. As of this week with 24400 miles on the truck I am getting the same intermittent message. The the message comes up with shuts down cruise control, makes a chime noise and turns on dash lights. The message will come up stopped to moving at any speed.
At 50k miles the ABS/Traction control lights illuminate on and off, cruise does not function as well. The code states ABS pump and/or electronic controller. The dealership is replacing both and updating software for $1600. Researching the HD Ram forums I found this is extremely common for 2017 and 2018 models. the federal safety agency as of November 2022 is investigating.
ABS and Traction Control warning lights flash on and off constantly and there is a warning tone that beeps non-stop on my 2018 Ram 2500. When these warnings appear, the ABS System and the Traction Control are disabled along with the cruise control. This has happened twice already, and my truck only has 4000 miles on it. The first time was in October 2021 when the truck had under 3000 miles on it. The dealership replaced the ABS pump which fixed the problem temporarily. In August 2022 the same problem appeared, and the same warning lights came on. At this time the truck had around 4000 miles on it. I took the truck in for service in October 2022 and even though the truck was out of warranty, I still had an extended warranty contract. This time I was told it was the ABS Control Module and that the part was on backorder for 3 months or more and that since they could not get the part I was not covered by the extended warranty and was charged a $175.00 diagnostic fee, but that if they were able to get the part that I would have been covered by the warranty. All the dealership was able to do was reset the code which lasted for about 20 minutes before the problem started again. It is now December 28, 2022, and I have had to drive around for the last 6 months with the dashboard flashing and the truck constantly beeping and with the ABS, Traction Control and Cruise Control disabled. I have seen hundreds of complaints regarding the same problem and yet Dodge has not issued a recall regarding this issue. It's beyond comprehension that my truck has had the same problem twice and it only has 4000 miles on it and now Dodge is telling everybody that the part is not available until next year, and so everybody that has this same problem has to drive their truck around with flashing warning lights on the dashboard and a constant dinging tone which gets very distracting and annoying, and on top of that their ABS and Traction Control is disabled. This was my first and last Dodge.
ABS module failure, part has been on back order over 2 months, was told by 2 dealers this is a common problem and to limit driving, this problem also affects the towing features and will not allow the trailer brakes to activate.
Service electronic brake/ service ABS warning lights come on intermittently causing cruise control to disengage. This is the second time this issue has arose. The first time the dealer replaced the HCU. This is a common problem and needs to be addressed and a recall initiated. The parts seem to be defective because this problems continually occurs.
I have the dreaded Ram 2500 ABS/HCU issue. Light constantly coming on/off, appears to hinder the abs from working, very noticeable when towing the boat in the rain.
