C0020 - ABS Teves/TRW Recirculation Pump General Electric Failure Error Intermittent. Approx. Dated Occured Nov. 15 2023. ABS Module and Traction control goes off-line intermittently during drive tests effecting ones ability to stop safely and prevents ABS pulsating Hydraulic braking when towing locking up vehicle brakes effecting driver and adjacent traffic/pedestrian safety. Vehicle is currently being serviced by an independent dealer but I have managed to replicate the issue on test drives and error is logged as a permanent code within the OBD II ECU Ram Module confirmed by Autel System. Warning lights did appear when or at the moment the system failed not prior.

I own and drive a 2018 Ram 2500. This morning on the way to work the "Service Antilock Brake System" & "Service Electronic Braking System" error messages are popping up on the dash on and off. This is the 3rd time I have received this problem and the truck only has 42,200 miles on it. The first time the dealer replaced the ABS module and HCU at only 15,486 miles. The second time the dealer forced me to pay for these parts knowing that this is a manufacturer defect and a widely known issue. When this happens the trucks ABS system and traction control does not function properly posing a huge safety risk! I don't know if my trucks brakes will work properly, are reliable or if I can even drive it. I am now forced to rent a car until something is done about this. This issue has been reported many times over and is wide spread all over social media. It affects thousands of people that own these trucks from 2017 to 2018. failure TSB Number: S2005000004 and NHTSA Action Number: PE22012

Intermittent ABS / traction control light diagnosed as the ABS / hydraulic control unit. I see this is a very common issue and very dangerous.

Anti-lock brake system module is out causing hard brakes and pulling which could cause a wreck. This is a known problem and has been reported by many 18 Ram 2500 owners. My truck is not safe in this condition and there needs to be a recall to make these trucks safe.

The ABS and HCU are bad in my vehicle. It appears to be a widespread issue with this year model. A recall should be issued by the manufacturer to correct this safety issue. I recently collided with a barrier wall because my ABS system was not functional.

Abs module failed for the second time. Braking is not predictable without abs system

Truck has 15500 miles on it. ABS and electronic braking system light comes on and off randomly. Causing me to lose traction control, cruise control and ABS

The abs and traction control keep lighting up and lose both while driving.

The ABS and Traction Control System light and warning engage intermittently when operating. The alarm startles the driver and unsure if system works

After a hard braking event Service Electronic Braking System and ABS warning CEL came on. Goes on and off intermittently sometimes 20-30 times in a mile of driving.

"Service Antilock Brake System" & "Service Electronic Braking System" error messages are popping up on the dash on and off while truck is running. Sometimes pop on after starting the vehicle while sitting in drive and other times while driving.

Loss of ABS. The hydraulic abs unit failed they are on nation wide back order cannot get them. 2018 are not recalled yet only 19 and newer have been recalled for this issue. Truck losses abs and due to that losses traction control. Very common issue in all 2018 ram 2500. Very dangerous to drive a big heavy duty truck with no abs.

Truck has 26xxx miles on it. ABS and electronic braking system light comes on and off randomly. Causing me to lose traction control, cruise control and ABS. Dodge dealership run diagnostic on it and stated it has a bad HCU. Their are currently about 400k trucks with this same issue. Dodge is aware of the problem and the safety hazard of this issue. Dodge refuses to issue a recall. Cost to repair is $1000. Please force dodge to issue a recall and take responsibility for this mechanical failure

The contact owns a 2018 Ram 2500. The contact stated while driving 5 MPH, an alarm sounded, and the ABS warning light and the traction control warning light illuminated. The contact stated that the failure had been recurring while driving at various speeds. The contact used an OBD scanner and retrieved DTC codes: C0020, C211B and P0579. The dealer was contacted, and an appointment was scheduled for a diagnostic test and repair. The dealer also informed the contact that it was a known failure and one of the parts needed was on backorder. The vehicle was not repaired. The contact related the failure TSB Number: S2005000004 and NHTSA Action Number: PE22012 (Service Brakes, Hydraulic). The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 23,900.

Abs module and can't replace because back ordered

This vehicle has had a recall on ABS module and HCU for ABS. The replacement is now repeating the same issues as the original within a few miles. (Service ABS, traction control, and various other lights flash intermittently, causing the cruise control to turn off suddenly, which represents a huge danger.) Not to mention the constant bells and whistles being distracting.

ABS and traction control indicator lights start flashing and became intermittent during a road trip. I took to dealer and they replaced the abs motor pump and controller this happen 11/21 and after the warranty expired. 3 months ago it flashed a couple of times and now is flashing intermittently each day and will cost another $1600 to replace. The code is C0020-01 and is attached. This happens about 1 min after I start the engine, goes away for a few minutes until I hit some bump in the road and it triggers.

I have been dealing with the abs light going on & off with alarm constantly for over a year now. The HCU and ABS module needs to be replaced from what the dealership tells me. I don't understand why there's not a recall. Still waiting on the part to become available.

During normal operation the ABS, Traction control and electronic braking system warning lights came on. Now when i am driving the Service electronic braking system lights will come on and off intermittently. Some times if i hit a bump it will come on briefly. My cruise control does not work and from what I've read my 4 wheel drive may not work. I live in the snow belt and use this truck as primary transportation as well as plowing snow and for our business. Im told this can be a brake module. I only have 40000 miles on my 2018 ram big horn. should not be having these safety problems.

Warning lamp repeadly blinds on dashboard to service abs brake system. turns out this is a common problem with the ram abs control module going bad. this is confirmed by dodge dealership and there's a long waiting list for the replacement part. driving with afaulty abs module results in poor braking performance.

While normal driving of my 2018 Ram 2500, I began to get random audible warnings, service anti-lock brake and service traction control system dash lights. The lights would flicker on and off and warning chime would 'bing" numerous times. This caused the cruise control to shut off while doing 65mph. Some drives I would get nothing, others would be a solid 5 minutes of flashing and chiming. Scan tool identified the C0020-01 DTC. ABS pump motor control general electrical failure. Appointment was made at local RAM dealer and I was told that the parts are unavailable and on national backorder. I am now uncertain driving the truck as I do not know if the brakes could go out randomly or fail completely. Upon researching this fault, it seems to be a very common issue with the 2018 Ram trucks.

Anti=Lock Brake System- Hydraulic Control Unit. I bought this truck new. HCU has already been replaced once while truck was under warranty. Unit has failed again. I have been driving and trailering with a faulted ABS system since 10/22. Been to dealer for repair. No replacement units available.????? And it is constantly ding donging on/off as it faults. Can not trade it in with the fault. 70k$$$ truck! They should buy it back if they cant provide a solution or parts. And they expect me to pay for it if it is repaired a second time. Said 1st replacement warranty ended with the truck warranty. I have worked for a top automotive fuel injector/ABS Module manufacturer for the past 28yrs and I can tell you- This Is Not Acceptable.

Anti-lock brake / traction control lights come with audible chime. Message reads service anti-lock brakes and service electronic brakes. Problem is intermittent with light coming on for a duration then going out and clearing message center. At times, the warning lights turn on and off rapidly giving multiple audible tones. Activation of light causes deactivation of cruise control. At highway speeds - rapid deceleration occurs. Unknown if the anti-lock brake or traction control will function while light is on. This will be the second time this issue has occurred. First time repair was covered under warranty for same issue. Diagnostic’s performed at authorized Ram dealer (10/27/2023) (Approx. 48500 mile's) indicates issue with Anti-lock brake control and Anti-lock brake module. Remedy - replace defective parts with: 68143491AB Control: Anti-Lock Brake 68347098AB Module: Anti-lock brake Total cost to repair: 1478.25 Dealer states that no factory warranty on this repair. Parts not available until February 21st 2024

While driving the truck my ABS, Traction Control and red brake symbol come on the dash as a warning. The vehicle once this happens no longer can utilize cruise control nor its ABS system during hard braking. This problem began intermittently and has become permanent. Dealerships are unable to get parts for repair.

I was driving my vehicle and a car in front of me stopped at a traffic light. I attempted to brake my truck to stop the vehicle and I only had limited braking power and hit the vehicle n front of me. I had been experiencing intermittent ABS and Traction Control lights and I had a mechanic check all the wheel sensors and replaced one sensor that was damaged when the sensors were checked and cleaned. I had no indicator lights on prior to the crash and the ABS and Traction Control lights were illuminated after the crash. This was verified by the officer onsite at the crash.

ABS control module is bad. Makes abs and traction control lights blink on and off erratically. Have had it replaced over a year ago under warranty for the same problem. Now it's doing it again and was told part wasn't going to be available tell February of 2024.

ABS and Traction Control lights coming on at random times. With Code C0020-01 Failure in pump motor control circuit.

ABS light comes on and off constant. Service abs system, service electronic braking system. Ram came up with the code HCU hydraulic control unit failure. They will not fix it unless I come up with the 1500$$ to fix it out of pocket. My truck just turned over 60k this is ridiculous. Go on google and please type this in. It a massive issue in all 2018 rams. Should be a recall at this point. If you guys can fast forward me to get repaired please let me know I feel as if this could cause harm if the brakes lock up or I get in a skid situation if could cause harm to myself or others or properties. Please call if we can nip this in the bud. [XXX] . Thank you to whom will be reading this and I really look forward to hearing from you. I honestly can’t afford to just dish this out of pocket cost for something that should be under warranty. 😞 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I own a 2018 Dodge Ram 2500 with Cummings. My dashboard Anti-Lock Brake lights flash on and off and sometimes stays on and always turns off my cruise control. I’ve called the Ram dealers and they tell me the Anti-lock Brake System Module is on back order till next year. I’m nervous about my life and others on the highway who are driving with me. Can you HELP me. I have not been involved in a car accident yet but easily can happen [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am getting an ABS sensor warning that was previously fixed 3 years ago under warranty but is now resurfacing. It is a constant alarm that prevents the cruise control from engaging.

Intermittent dash flashing of ABS and "service electronic brakes" messages tied to known HCU/ABS module fault/failure. C002-01 code. Driving over light bumps trigger lights on/off. Dealership told me to ignore lights and code.

REPEATED SERVICE BRAKING SYSTEM WARNINGS. KNOW ISSUE FOR ABS with these vehicles. Code C0020- ABS pump motor controler.

When I had to use excessive pressure on brakes, I received a DTC and a messaged flashed on my display to service ABS system as well as TCS. I had the DTC read which showed C0020-01 ABS Pump Motor Control General Electrical. It was cleared but when I drove over a speed bump at my kids' school, the same message displays. The message has also displayed during wet weather and minor wheel spin (over white painted crosswalk lines) from a stop. I spoke to a technician from the Chrysler dealership and was informed this has become common and to file a concern here.

2017 & 2018 Ram trucks have have a lot of ABS brake failures. I only have 30,000 miles on my truck. At 22,000 miles I had a ABS module replaced. Now at 30,000 miles I need another ABS module replaced. The problem is Ram does not have any ABA modules available. I am hearing they might have some by March. According to the Ram dealer, Ram is designing a new one because of all the failures. So that leaves a lot of Ram trucks on the road without ABS braking. Not a good thing to happen with winter coming on. Someone needs to address this problem with Ram. Thanks

Hydraulic control unit failed causing abs and traction control lights to intermittently flash on and off. Dealer says replacement parts are discontinued and not available until at least February.

My truck was repaired in September of 2021 at a dealership due to a faulty HCU for the ABS system. I got a famed Ram service electronic braking system message along with service ABS system. After being replaced, I now again as of three weeks ago (10-21-2023) have the same service electronic braking system message with an electrical fault code for the HCU. After visiting the dealership, I was told there were not parts to replace it at this time and they could do nothing for me. Also, my service rep stated that Stellantis is reengineering the part due to known faulty problems however time frame is unknown. With this light on I have no ABS, no traction control, and no cruise control. The no ABS and traction control is a major issue for a heavy duty truck especially while pulling a trailer as brakes can now lock up due to no ABS control. This is obviously a safety issue and I'd hope this would become a recall and quality safe parts would be utilized to fix it.

ABS Control Module causing ABS light to come on, consistent audio warning, and disengages Cruise Control function. Currently being diagnosed by Dodge dealer the ABS Module and Hydraulic Control Units failing internally. Initially it was very seldom, and now is constant.

Truck has 44,945 miles on it and began showing intermittent ABS and Traction Control lights on the dash. This is a known problem on RAM trucks which the ABS module or the Hydraulic Control Unit needs to be replaced. I have noticed lack of braking power when this fault appears on the dash. Both while pulling a 9,000 lb RV and without pulling anything. The vehicle scan showed a C0020-1 ABS (Anti-lock Braking System) Pump Motor - General Electrical Failure.

ABS Brake control warnings have been flashing on and off for many weeks. Took it to the dealer that sold me the truck and they said that they cannot get the parts and it may take several months or longer. I did some online reading in RAM truck forums and this is an ongoing problem for many 2018 RAM truck owners. Some have been waiting over 5 months to have the ABS control modules replaced and all of us are having to drive an unsafe vehicle while waiting.

Service ABS light comes off and on sporadically. This is a known problem through out the country and needs to be addressed by a recall.

Trucks and electronic braking and traction control randomly quits working.

Vehicle started flashing “Service ABS Braking System” and “Service Electronic Braking System” intermittently. There is no rhyme or reason and no way to make vehicle reproduce this at will.

My Ram has about 31,000 and about 5,000 miles ago it kept randomly giving me a message to service the abs system and traction control message. I took it to the dealership and they informed me that it's a common occurrence for my model truck and they replaced the abs module with the same part number and said they're working on a revised part to replace it. They told me that the abs is not working all the time because faulty part which seems like a safety issue. I did some research online and a lot people are having the same issue and are waiting for the new part which is said to be available sometime next year but we will most likely be forced to pay for the new part and labor. Hopefully you will be able to get them to do a recall for this issue. Thanks

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. I am adding the first date below. The second failure was 12,000 miles later after the first was ABS was fixed. 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.

Automatic brake system module, HCU abs pump. SAFETY. malfunction of part. Known to be world wide problem. Confirm by dealer scanner code. Continuously, warning light and alarm. Response from dealer manufacturers of 2018 ram 2500 diesel, known problem, no recall. Dealer for part can not give time, date when part can become available. Can not give time or date when part will be available?

Anti-lock braking system rendered inoperable by defect hydraulic control unit. ABS inoperative, frequent audible alarms and flashing lights on dash. Dealer explained that problem is common and that replacement part is not available until May of 2024 at the earliest. This vehicle should be recalled. Federally mandated ABS is inoperative and cannot be fixed for at least six months. This vehicle is my daily transportation. Dealer told me that I'll "have to deal with it" till parts become available. Vehicle almost left the highway during braking on a downhill in the mountains in rain. Vehicle was towing just over 5000 pounds at the time, well within tow rating.

Service Antilock Brake System warning on at 19,600 miles similar to the many ABS/HCU failures reported on 2018 Ram 2500 trucks.

ABS light and traction control light comes on all the time and when lights comes on curse control stop working, by lights coming on all the times don't feel safe to drive truck.

ABS and Traction Control lights and associated chime intermittently (but relentlessly) turn on/off/on. This happened while towing a trailer in mountains and disabled my ABS, traction control and cruise control. This 2018 Ram 2500 4x4 has only 17,100 miles. The codes C2200 and C0020 that it shows, according to Ram, require an ABS module and hydraulic control unit. The latter is unavailable and even if it was, is known to fail again regularly within a couple of years. This is a HUGE safety issue we need help fixing.
