Braking problems / ABS module failure. I never lost brakes but the ABS did fail and the ABS module and HCU had to be replaced @ 17400 miles at roughly 2 years old.

- Queenstown, MD, USA

The service ABS warning intermittently would go off causing the brakes to function erratically and unsafely for both the truck and tow trailer. Replacing the HCU has resolved the issue.

I was driving at highway speeds when the abs / traction control light came on. Notice cruise control was inoperative. The next day the warning lights were off. On the way home from work the system quit functioning again. After diagnosing found codes C0020-01 & U0403-00. ABS control module failure. I was told by the dealer this safety issue was not covered under warranty.

Service ABS message with loss of traction control and ABS performance required replacement of ABS and HCU modeles at dealer, Orr Ram in Russellville, Arkansas, in April 2021 under warranty. Now 18 months later, the same issue has occured with ABS and Traction control loss. The service ABS message will appear, then disappear several times in a 40 mile trip. The vehicle had 28350 miles. Two ABS failures in less than 30,000 miles!

"Service electronic braking system" and "service antilock brake system" are popping up on gauge cluster at highway speeds. This is a random event that started at about 35,000. The system shuts on and off constantly with chimes and alarms to -??Service electronic braking system" and "service antilock brake system". I contacted the dealership by phone, and they said they know about this issue but there is no Recall yet and it-??s not covered under powertrain warranty; they advised it needs to have the ABS pump and control module replaced. I have looked on the internet and see several thousand complaints for the exact same issue. To me this seems like a life/safety issue that is being ignored Stellantis / Ram.

HCU unit failing. Keeps throwing service abs, and service electronic brake controller. On off on off on off non stop constantly the whole time truck is almost undeliverable Part is unavailable due to supposedly back ordered. Been told part is known issue and that a recall should be done but it-??s not. Hydraulic control unit. So driving a one ton truck with failing abs, traction control with no delivery date of a part that is junk.

Warning ding and dash indicates that the brake system of the car is failing. Actual message is Service Electronic Braking System After researching this it's clear that this is a massively widespread issue with all dodge ram heavy duty trucks. The repair requires changing out the ABS module from what I'm reading. My truck has only 20K miles on it and is near new condition, I can't afford to pay thousands to have the brake system repaired at my cost no a near brand new truck. This is impacting the ABS unit which would be a serious risk during slipper conditions when it is needed most.

HCU Issue: The ABS light coming on is the lightwill come on for two second and go off at times, through the diagnostics of the code C0020-01. It is a general electrical failureto the hydraulic control unit. The unit is replaced separate from the ABS moduel th HCU needs to be replacedfirst. In some cases, the ABS module that is bolted to the HCU needs to be replaced and programmed as well. The HCU needs replacement first. The total estimate is $1010 with labor. Any questions, please call Bruce at Albany Chrysler. 320-845-2801. This is an intermittent issue, that comes and goes.

2018 Ram 3500 4x4, driving down road hit bump service abs light and traction control light came on causing the ABS braking system to be inoperable. Took the truck to dealer where they diagnosed problem, ABS pump module needed to be replaced but was not under warranty they are trying to help me in this matter. Researched problem at home and looked up recalls, my truck was built in the time frame when a recall was issued but this truck was not included in recall. After reading many Ram truck forums this exact same problem has affected a lot of trucks exactly like this, I feel when a problem has affected thousands of trucks like this a recall is usually issued to resolve the faulty part especially being a major component as brakes are as well as a safety liability this is to the Dodge Ram corporation. Please answer the above questions as well as a solution to make my vehicle safe again.

2018 Ram 3500 - ABS system/Electronic braking system failure at 5583 miles. ABS/traction control and service electronic braking system display on dash, also audible chime with cruise control inactive. Took to dealership for diagnonis and code C0020-01 is active. Reccomended replacement of HCU which is common for these vehicles. Truck is out of warranty and estimate is $1080 for repair, which does not include the $301 I spent on diagnostics. There needs to be a recall on these Chrysler HCUs as they are a known issue and related to the braking system. Why do I see recalls on items such as malfunctioning tailgate latches but not braking systems?

ABS/HCU are defective and must be replaced. We have no ABS or Electric Brake System which has also caused the Cruise Control to not work. This is a known issue with 2018 2500/3500 models but recent recalls don't list this particular year within the scope fo the recall. Online research found a multitude of 2018 RAM trucks with the same issue - Recall Z20 should be modified to include 2018. My 3500 was purchased for towing as are most 2500/3500 models and this is not acceptable to not have ABS as well as Electric Brake Systems. Will be months to get the parts for repair due to nearly over 300,000 Rams and Durangos alone in the current Recall Z20 affected. (Incident was stopping to avoid hitting deer and no ABS. Next day when started up vehicle warning lights: Svc ABS and Svc EBS.)

ABS and Traction Control lights and DIC alarms came on while driving. They stayed on for a few minutes then went off. Also the service trailer brake system message came on. This has happened several times now turning off cruise control too. I reseated all fuses and went for two weeks before it started happening again. Happens sometimes as we go over expansion joints or hit potholes while driving at highway speeds. I notice several other reports of this here at NHTSA site and various RAM forums across various RAM years.

I am getting two errors: 1) Service anti-lock braking system with the ABS light on; 2) Service electronic brake system with the traction control light lit.

Abs and traction control system stopped working with only 33000 miles. Dealer states module and pump need replacement. No warranty as vehicle is 4 years old as no driving during covid. This has happen to 1000's of ram trucks. Repair is $1600. Will have to drive with out repair.

ABS and EBS sytem is shutting on and off on highway at speeds. This is a random event that started at about 20,000 miles then went away for about 6,000 miles then came back at 29,000 miles whil on a 1,500 trip and is now not going away. The system shuts on and off constantly with chimes and alarms to "service ABS/EBS. I have the truck at the dealership and they advsied it needs to have the ABS pump and control module replaced. I have looked on the internet and see several hundred complaints for the same issue. The delaer says this is not a recall and is not covered by warrenty. To me this seems like a safety issue that is being ignroed by Chrysler corp / Ram. They are looking at the numbers and not enough people have been in accidents to justuify the cost of a recall. I have a video of the issue system turning on and off constntly at about 62 MPH as I enetered the freeway from and on ramp to merge in trafic.

A 2018 3500 Ram with 31K miles just experienced two warnings on the dash. 1. service electronic brake system 2. service anti-lock brake system diagnosed using obd by midas: Both ABS module and pump are going out. Vehicle is not considered safe to drive. Area is backlogged for these parts (1000). This is a major safety issue as I'm told this is a cronic problem. Cost to repair is exceeding $1800 not including the diagnosis. Called our local Dodge/Ram dealer and they said it is not on any recall. Why not? its my understanding that NHTSA initiates safety recalls when vehicles are in peril of crashing due to a failure. We made it home but if it went completely out, we would not be having this discussion.

Truck has 22000 miles ABS and traction control lights constantly coming on and off along with service electronic braking system warning. Kicks the cruise control off every time it pops up. The cause is the abs module which apparently is a very common issue on these trucks and costs over $1000 to repair

- Brandon, MS, USA

The ABS Anti lock lights came on and says check Electrical Brake System. Dealer said The ABS anti lock brake pump assembly was bad and it was on me to replace it. This is a big safety Issue to me. I got a 2018 3500 ram and paying big money for a truck and my safety, there should be a recall before some people get kill.

ABS and Traction control pump system electrical failure. Went to a Dodge Dealer and had the system read due to light coming on and off. Originally started around 38,000 miles on the truck. A code came up C0020-01. ABS pump motor control electrical failure. Researched on the net. Seems to be a big issue from 2013 on up on trucks. Chaffing wires" Pump failure" Dealer said the ABS Pump could Possibly be bad. Wondering if there is a safety Recall or will have one. I have my truck scheduled for repair next week. Estimated cost of $700 according to service department.

The warning chirp occurred and the ABS and ESC lights came on the first two times. The incident happened so quickly I could not clearly determine which warning lights illuminated. On April 18 with just over 39,000 miles on the vehicle the chirping alarm and the ABS and ESC light illuminated. In addition two warnings appeared in the dash: "Service Antilock Brake System" and "Service Electronic Braking System." The warnings happened multiple times per minute in some cases. Other times the vehicle would go for many miles without the warning. Every time the warning chirp was heard the cruise control would disengage. I did not notice any problems with the brakes of the truck. In researching the issue I learned that many people are having this problem. I contacted Ram and they directed me to a dealer who diagnosed the C0020-01 fault code and that the hydraulic control unit (HCU) for the ABS system was defective. According the the TSB Ram has put out about the issue the ABS module could also be bad, but the first part of the repair it to replace the HCU and if the problem persists to then replace the ABS module. Ram apparently has an inconsistent level of support for owners experiencing this malfunction with some getting the repair done out of warranty, while others have to pay for the repair. Because it is brake related it seems this should be an item replaced as a safety issue, no matter what the mileage on the vehicle.
