Bought from a dealership a couple months ago (JAN 2024). Immediately started blinking electronic ABS error. Took in to get serviced, and now maintenance department is stating a replacement HCU and additional service will cost around $3.5k on a vehicle that has around 68k miles.

Abs and traction control lights on due to failure of ABS module and pump. No accident but feel there could be a problem in the future considering this is a safety issue
Service and systems and service electronics brake system warnings at approx 50000 miles. Dealer is saying it is an HCU failure
At 9,040 miles, display reads “Service Antilock Brake System” along with warning lights for abs and traction control and a loud dinging. It goes off, then back on multiple times until serviced when the dealership replaced the faulty HCU Sept. 2020 under warranty. Diagnostic code C0020-01 ABS pump motor general electrical failure 2023 the problem comes back but nothing done. 2024 after much research, found the newer replacement HCU had just been revised in April with a new part number. At 25,837 miles back to the dealership for another replacement, this time paying out of pocket, over $300 for part and over $600 for labor. It’s only been a short time but so far, no warning about a faulty abs. I do have the old part if inspection is necessary. There is an FCA service bulletin out #S2005000004; the federal safety agency #10181550 It says if the HCU doesn’t fix the problem, replace the ECU, but that is not available and no ETA. Lucky to get the HCU because that is a very limited part. This is a safety issue because not only does the ABS and traction control go out but you also lose cruise control and 4wd while driving. There should be a recall with all the complaints. Not sure what good a recall would do if parts aren’t available anyway. Telling someone who just spent a fortune on buying this truck not to drive it because of this, is not an option.
The known issue that Ram refuses to is plaguing my truck. ABS and Traction Control lights come on. This shuts off the cruise control as well as makes braking difficult. It is very dangerous. This is a ticking time bomb. Vehicle has under 50k miles on it. 2017 and 2018 have been known to have faulty ECU Module and HCU. Loss of brakes momentarily occurred on [XXX]. I am having the issues under investigation. the federal safety agency Action Number: PE22012 Components SERVICE BRAKES, HYDRAULIC Opened From: November 28, 2022–Present The reports cited below can be reviewed at using the following ID numbers: 11143741,11182778,11231734,11252781,11265590,11270151,11300182,11319987,113409 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
For over 3 months the ABS Brake warning, the anti skid control and the cruise has not worked in my truck. I have had it to two different dealers, and opened a case with Ram. Case#89336043. They told me part is not available and has not been for the past year. Just drive my truck like it is??? I dont really know what options i have at this point. Please help!
ABS module problems. Flashes to check service ABS and traction control. Then goes away and comes back. Been having issue for over a year with no results in fixing
abs lite comes on no parts available 60,000 truck not safe to drive mine not only one ingoing trouble with a lot of
Abs/traction control light. Dealer says it needs a new abs module and pump. It’s too new to have these issues, dealer states that it is not a recall and I would have to pay out of pocket ($1600) for the repairs. This is not safe at all. I live in indiana and doesn’t like stopping when the road is snow covered. Ram/chrysler needs to have this recalled immediately. This is very dangerous!!
Getting the "Service Electronic Brake System" alarm. Had this when it was under warranty and it was "Fixed". I am now getting this same error again. ABS, traction control and cruise control are all disabled when this warning occurs.
The ABS light and traction control light comes on intermittently, from my understanding this controls the stopping power of the truck. I have no traction control when I am pulling my camper. The lights will go off and then come back on own their own, even when the truck is sitting still with nothing hooked to it.
Intermittent flashing and dinging for ABS system. Message in dash says “Service Antilock Brake System”. Has been diagnosed and confirmed by credited service shop. The problem occurred around 80 thousand miles, a year or so ago.
My ABS and Traction control lights will come on and off, making my cruise control stop working without warning. sometimes it stays on and sometimes it goes off. it is completely random. I'm seeing lots of reviews saying this is happening to others and its the HCU module and the abs control. please help get this fixed
ABS and traction control lights constantly flash electric brake assist also flashes intermittently.
ABS and traction control light comes on sporadically during driving. C0020-01 ABS Pump motor control general electrical failure. This appears to be a common problem with the 2017-2018 model RAM trucks. Parts are on national backorder.
Abs code c0020-01-ABS pump motor control - general electrical failure
Abs module issues needs replaced but parts aren't available through the manufacturer
ABS and traction control lights intermittent flashing. Service ABS warning flashes and chiming occur. Very distracting and makes me unsure of failure of system .Codes and stored messages clear and repeat. Cannot go to dealer every day to have codes read that don’t exist. Parts not available at dealer. How is this fixed?
Component: ABS hydraulic control unit. Part No 68143491AA Risk: Vehicle lost ABS capability Confirmed: No Inspection: No Warning lamps: Control unit exhibiting similar problems was replaced in 2020
3 yrs ago, took to dealership for light for electronic brake module, was told that the part was on backorder. Picked up truck and was told that they would let us know when part came in, have called and spoken to at least 11 different service reps and a managers (Dodge as well) over the last 3 years. They close the tickets after a certain amount of time and you have to explain yourself over and over and get the same answer, the part is on national backorder. Our warranty expired 10/2023, there is still no recall on our truck but other truck have a recall. I have tried and called the 1-800 number to get help with this matter and still we have a vehicle that we may cause injury to us or others. Please help!
Abs electronic brake light issue,brakes spongy and feels like it’s lost braking power.
The Anti-Lock Brake & Electronic Braking System error caused the internal Trailer Brake system to shut off trailer brakes just like it shuts off the cruise control when warnings come up on the dashboard. The incident happened Aug 28, 2023 while following my son and my wife in a vehicle ahead of me. I had to change lanes to try to avoid something that suddenly came across in front of my vehicle. I applied the brakes and then the trailer acted like it didn't have any brakes fell over & was totaled. If this was in traffic someone could have been killed. The "Check Anti-Lock Brake System" & "Check Electronic Brake System" warnings started coming up intermittently as I drove my RAM 3500 Diesel truck starting sometime around July 2023. I drove to the local RAM dealer and told them about the problem. They acted like they had never heard of this problem and proceeded to check the error code and then stated they had never heard of this error before. They said they would check with RAM engineering on what needed to be done. They then said there were other similar RAM trucks with the same issue & that the parts were on back order. I finally got an appointment for the dealer to check my truck after sending an email to the Service Supervisor. After they checked my truck on August 16, 2023 they said that my truck needed a new Anti-Lock Brake Control Module. I had seen that many others on the internet blogs had stated that both the Anti-Lock Brake Control Module and the Hydraulic Control Module (HCM) needed to be replaced. I was then told by the service person that the Anti-Lock Brake Control Module would not be available for months (until sometime in December) and the Hydraulic Control Module (HCU) had no date of availability. They also checked with the RAM technicians at the dealership about safety driving the truck and towing a trailer until the part came in. They told me that only the Anti-Lock Brakes may not work so it would be safe to continue to drive it and tow a trailer.
Service Electronic Brake System Warning. This warning started coming on sporadically. When the warning appears in my dash, I will lose abs function, traction control, and cruise control. This appears to be a common problem with this year Ram truck. The fix is an abs module, and or, a hcu module.
Traction control and abs lights have been coming on randomly while driving over the past several years. Seems worse and more frequent in cold temperatures. Scanner reads code C0020. Cruise control suddenly shuts off when this happens causing a safety hazard especially to those traveling behind. Dash lights and constant chimes are very distracting while driving. No abs makes winter driving more dangerous as well. Seems to be a common problem with this vehicle. There should be a recall issued to fix this.
ABS light and Traction control light turn on and off constantly
Service electronic brake system, & service hydraulic brake system warning lights intermittently display on dash. Disables both of those safety features as well as cruise control. These are very important safety features especially when hauling a load!
ABS and traction control warning lights intermittently come on. Has been repaired twice by local dealership by replacing the two computer modules/pumps responsible for ABS system. Cruise control disengages when this happens. When this happens at highway speeds while pulling a heavy trailer in traffic it's a very dangerous situation and needs to be corrected by manufacturer.
My 2018 Dodge Ram with 7175 miles on it has a continuous service anti lock brake and service electric brake light go on and off.Cruise control inoperable as it shuts off when the warning lights go on and off.Dealer did a $160.00 diagnostic on the system that I had to pay for only to tell me the hydraulic control unit needs to be replaced at a total cost of $825.00 that I am responsible for.Additionally,the part is “controlled” by the manufacturer and they are allotted one unit per week.No time frame when the vehicle will be repaired.This is a safety issue especially when the constant “chime “ goes off which is very distracting.I haul a camping trailer with this Ram 3500 duelly four door diesel four wheel drive and the braking is questionable.
My ABS and Traction Control components in my 2018 1-ton Ram are intermittently setting codes with the ECU, leading to loss of ABS, Traction Control, and inability to use my cruise control. I am concerned that I have a loss in braking performance without those components operating as designed. I have brought my truck to the local Ram dealer only to be told that the module will not be available for install until Feb of 2024 after an upgraded unit is made available to the dealers. I feel that this should be a recall, as a quick internet search shows multiple owners of the same vehicle are also affected.

Purchased this truck specifically to tow 14000 lb fifth wheel camper. Two months ago warning chime and “service electronic brake system, Service antilock brakes and Traction Control” caution lights repeatedly activate. I am concerned about towing in this condition if operating on rain slick roads and winter weather. Also the constant chime is a serious distraction. Truck is currently at the dealership for repair. 25000 on the odometer. Truck is out of warranty. These failed safety systems endanger mine and my family’s lives, as well as other motorist and the public.
