Abs and traction control malfunction. Yes,it’s it available for inspection. I feel that it’s not safe for my wife and I to drive while doing this. No it has not been confirmed by the dealer or service center. No it has not been inspected by police or insurance representatives. No there were not warning and starts at 150k miles have 158962miles on it now
I started getting an intermittent error code on my truck with only 36k miles on it. the traction control, abs and cruise control wont work when the service electronic braking system code is present. I have done a lot of reading and this seems to be a very common issue with the 2017 and 2018 ram trucks. It is so common that I called my local dealer and the part is on back order for months. I am getting very close to taking a long road trip with a 20ft trailer, which is the reason I purchased this truck. Now I cant even get a replacement part, that is a known issue and I was quoted $1100 for it. Braking system seems to be a safety issue, why isn't ram doing something about this issue!
On September 8, 2024, I started getting intermittent ABS and Traction Control light with “Service Electronic Braking System”. Code C0020. When the light is on I lose cruise control. There is no specific condition that will cause the light to come on; i.e. bumps in the road, a certain speed, or setting at idle. The first instance of the light coming on, I was turning around in a parking lot, less than 5 mph. This cannot be associated to normal wear and tear. THIS IS A SAFETY ISSUE AND MUST BE A RECALL!!!
The anit-lock breaks on my vehicle will go out at random. This seems to happen when you need them most. In my case I was towing an 8,000 lb trailer and had to stop short. The anti-lock break and traction control lights came on simultaneously and the right front tire locked up making it difficult to steer the vehicle. Since that event the light will come on at random when hitting a bump in the road or when breaking hard. A driver might think the ABS system is working until they hit the brakes and it fails. This appears to be related to the federal safety agency Action Number PE22012 and I would like to add my vehicle to the list of impacted units.55
My ABS , service traction control , parking brake, anti lock braking all are on and dinging on my dash board. All points to the ABS module per the dealer . Will this be under recall I see the is a recall for a ABS soft ware up date now but my truck is not on that recall. This could fix my problem and do not understand why my 2018 ram 3500 is not on that recall or a recall has not been done for the ABS module.
On my 2018 RAM 3500 Duel rear wheel truck the ABS Pump Motor Control Unit is throwing a common code and warning lights intermittently that other year models have (C0020-01). This code has been confirmed by my dealer several times and this truck does not fall under any recalls for the ABS systems. I pull a 40 camper with this truck and with out the ABS and Traction control it could be very dangerous to myself and and others. I have spoken to FCA and they only told me that my VIN does not fall under any more recall then what has already been done. I do not know what needs to get done to have FCA fix this problem or release parts to get it fixed.
ABS Hydraulic control unit failed. ABS control unit failed. Vehicle has 60k Miles on it. safety item as ABS brakes may not work correctly in an emergency situation. very unsafe in a tow vehicle designed to tow/carry heavy equipment. forums indicate very common failure item, and parts are currently on back order with the manufacturer. confirmed failure by local dealership.
Intermittent chime and warning that anti lock brake needs servicing. Cruise control does not work when notice is displayed and chiming. warning comes and goes randomly After researching this problem it appears that this is a regular problem on this year ram truck I will report and take to the dealer if problem remains.
Failed abs module and/or hcu. Truck is available for inspection. Loss of abs and traction control causes loss of control of truck in wet conditions when stopping or cornering. Hcu was replaced by dealer 10/12/21 @ 20,109 miles due to code c0020. (Abs pump control motor general failure) Same issue/code @ occured again @ 47,000 miles. Have not been back to dealer as the truck is out of warranty and the cost is almost $2000 for the repair. Service Abs/traction control/ electronic brake warning lights constantly go on and off and eventually stay on. This causes abs and traction control to be unreliable and is extremely dangerous on wet roads and also dangerous to other vehicles on the road.
Antilock Braking System failure with my 2018 RAM 3500 Dually. The vehicle’s anti-lock brake system error, also causes the cruise control and traction control systems to become inoperable. The old HCU is currently on the vehicle for inspection by additional parties. This issue increases the risk to safety to vehicle occupants and public, for control of the vehicle, under wet or slick road conditions. As mitigation, while dealing with the defective part/system, drivers need to remember to operate vehicle differently in adverse conditions. Both a local shop and the Doge/RAM dealer confirmed the HCU needed to replaced. RAM MOPAR would not sell the HCU part to local shop for quick repair. Then I waited 5 weeks for service appointment at the local Dodge/RAM dealer, 1 week for estimate, 1 week for HCU part to arrive and schedule appointment, then finally 4 weeks to get appointment to (hopefully fix the problem, plaguing RAM owners due to the defect). I already had the unit replaced at 41K under warranty by the Dodge/RAM dealer, but unfortunately I am 1K miles out of warranty (75,000mi) on the second event, and estimated to cost me ~$750. The defective Hydraulic Control Unit, HCU, started to fail around July 1, 2024 sending service messages intermittently, and progressively got more as time went on. Both a local shop and the Doge/RAM dealer confirmed the HCU needed to replaced. The old HCU is currently on the vehicle for inspection by additional parties.

We purchased the vehicle as a back up for when my husbands every day work truck is in need of service. The truck is from 2018 and now has about 40,600 miles because it isn't used often. The truck would start flashing a light saying service anti-lock brake system sometimes during the time the light was flashing it felt like the brakes struggled a little. We have sent it in to get repaired and they quoted us over $1300 of repairs because it needs a an abs module and pump.
Continuous intermittent Service ABS System / Service Brake System warning light and audible warning chime
Abs braking not working , HCU failing pump. Ram will not cover this very critical system which faulty part due to no wear from use .
Intermittent issues with the cruise control system and the ABS electronic braking system. The lights will flash on and off and the beeping is constant. If beating on the side of steering wheel will allow you to turn cruise control, then the ABS system will be okay for unknown reasons it will start flashing again and cancel the cruise control and the system will start flashing check the ABS electronic braking systems.
Truck wouldn't stop antilock brakes did not work. Been trying to get 68347098ab and 68143491ab for the last 3 years from ram but been on backorder for that long. Was going down gravel road and trying to stop but wouldn't one wheel locked up and truck went into ditch smashing fender and hood.
Lights and chimes constantly signaling trouble with ABS/Traction Control system. OBD 2 indicates ABS Module failure but have read online it could also be HCU pump, a connection problem or a combination of issues. At this point the warning lights are on constantly while driving. No cruise control available. Talked to dealership and informed they are aware of the issue as it is wide spread with several models. Long back order and wait times for upgraded parts. Seems clear it is a safety issue.
No antilock brakes for 3 years. The parts have been on back order for 3 years and still no sign of when be in. Always in back of mind if brakes will work or not when trying to stop truck.
My car keeps giving the warning that the ABS brakes need to be serviced.
A diagnostic code has been displayed for the Anti-Lock Brake System - C0020-01 —> ABS Pump Motor Control - General Electrical Failure. Going over a bump in the road will cause the ABS system to deactivate the cruise control. The diagnostic code can be cleared and the cruise control will resume. Reading on RAM / Cummins online sites, many say that either the HCU and / or ABS Module needed to be replaced and many submitted reports to the federal safety agency to start an investigation. No damage has been evidenced at any of the wheel sensors. With the ABS illuminated, it appears that the unit wouldn’t function if needed. The clearing of codes has been done numerous times. First noticed in about January 2024.
We bought this truck from a dealer in March of 2023. We were never informed by the dealer that the truck had this issue. ABS light and traction control lights come on & stay on for periods of time. Sometimes lights come on & off repeatedly while driving along with chime on & off. When lights come on, there is no cruise control available to use. I took it to the dealer we purchased from over a year ago and was told there was no solution for the problem. They said it was under an engineering review. No parts were available for a fix. I have documentation from the previous owner that this was occurring when he owned it in April of 2022. Since we pull trailers with equipment and also a large fifth wheel camper, we feel very unsafe when the ABS braking system and the traction control goes out while driving this vehicle. It is available for inspection upon request. When will there be a repair for this?
1. Serv anti-lock brake system,. 2. service electronic braking system. ABS light on and traction control light on. Diagnosed issue is Hydraulic control unit and possible module antilock brake system. Dealership does not have the parts for repair. Manufacturer refuses to put a recall notice even though several complaints have been issued by the RAM community.

Abs and electronic control system lights intermittently come on and off constantly and have been for 25,000 miles. When it started happening Chrysler knew what the problem was hcu and abs module is malfunctioning but unfortunately no parts were available and couldn’t tell me when they would be available. I’m just now putting in the complaint due to just learning about this site.
HCU / ABS light lmaps started flickering and now stays on I only have 42k miles on this truck. When I researched come yo find out everyone is having the same problem with the 2017 and 2018 this is a safety problem that needs to be fixed. I was on a wet road went to stop abs light came om I slid alot scared me to death considering I was pulling a 10k lb trailer behind me. Anytime it rains I'm scared to drive this truck rear wheels spin way too easy especially with traction control not working and I don't trust the stopping after my incident. With so many more customers having this issue please have this fixed asap make it a recall someone will end up getting seriously from this issue and many have notified this site FIX THE PROBLEM ITS NOT SAFE
The abs light and the traction control light come on and you get the code for a bad abs pump and hcu. Codes are C0020-01 and code C0020-16
