The Hydraulic brake control has been a recall with no replacement part available for over 2 years and this causes many safety functions to not work properly including trailer braking. They have made parts for a 2500 model but neglected to fix the 3500, 4500 and 5500 models. They will fix it with another faulty sensor and still expect owner to pay a 1700 repair bill even though it’s a recall. It’s ridiculous on the time this is taking.

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.

The ABS system failure and traction control lights came on and have been coming on intermittently. This failure has caused the vehicle not to retain cruise control and brake and stability control being reduced or potentially off could result in an accident. Upon research, this is a very common and costly issue not covered by warranty work, this seems to be something Ram should fix as it is a safety issue.

We receive a ABS/ECS, electronic brake control warning intermittently. This also makes the cruise control shutoff. We had the ABS control module replaced once at roughly 12000 miles under warranty but it now is giving the same warnings and the truck currently has 22000 miles on it. My dealer stated this was a known issue and stated it’s fairly common on my model truck

I have a 2018 RAM 3500 with ONLY 20,000 miles on it. ABS and HUC critical parts are faulty, and I have no way to even purchase one until a recal is issued. Class Action Says 2017-2018 Ram 2500, 3500 Equipped with Defective Anti-Lock Braking Systems. No current part that resolves this issue. Ram 2500 and 3500 pickups are unsafe because they’re equipped with defective hydraulic control units (HCUs) and anti-lock braking systems (ABS). RAM knows about it and has ALL the modules on engineering hold. These parts have not been available for almost a year. No antilock brakes. No traction control. No cruise control. 4X4 four wheel drive system is locked out and cant be engaged after this warning occurs. Here's what they are telling customers who have filed with them about this. Good Morning Mr xxxx, As of 06/26, No new update Part: 68228991AD Module Order: xxxx Per CLIMS: Part STOCK is under QUARANTINE pending quality / engineering review and inspection. Working to obtain timing on resolve to predict allocation and shipment to DLR to fulfill No firm ETA to provide at this time. Pending response from SPLR / PKG Working to improve xxxxx Case Management 844-378-0575 Ext:4063199 My dealer said, be lucky if they ever have parts for a permanent fix. I can’t haul anything or use cruse control. Error lights keep popping up sporadically with dinging sounds, driving me crazy. It is "Service Electronic Brake System" with continuous ABS and STC fault warnings. This truck is dangerous to drive, a recall is a NO BRAINER!!!! I am writing for three reasons. 1. You need to get our dealer the parts now so we may have a safe vehicle, or 2. replace this truck with a new one if you cant repair ours ASAP, and 3. To make sure I have this all documented in case of any serious accident where you will have to assume all liability and responsibility if this occurs due to your lack of ability to repair this safety system.

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?

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.

Service Electronic Braking Service and Service ABS/TRACTION CONTROL. This is intermittent. When it happens Cruise control, 4 wheel drive and abs doesn't work. Happens when I'm towing my camper or not. Trailer brakes won't work when this happens. Hundreds, maybe thousands of complaints about this on Ram forums. This problem occurs no matter what the speed is. It even happens while sitting still.

The service electronic braking system and service abs system continues to ding and pop up on screen. Cruise control will not work either.

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; NHTSA #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.

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 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.

In July 2022 our 2018 RAM 3500 Diesel 4 by 4 truck started having an intermittent alert. Service electronic brake system, ABS, traction control. Cruise control is disabled during this alert. May 2023 the vehicle was taken to local dealer for a diagnostic. They revealed no codes were revealed answer was to replace the ITBM at a cost of 921.00. And the diagnostic charge was 233.00. I tried to contact the dealer for further questions with no cooperation. I started investigating and purchased a code reader at my own cost. The code that showed was C0020-01 ABS Pump Motor Control-Electrical Failure. Much different than the ITBM I was told. Fiat Chrysler Automobiles put out a Case Number: S2005000004 Release Date 04/28/2020 Symptom/Vehicle Issue: C0020-01-ABS PUMP MOTOR CONTROL- GENERAL ELECTRICAL FAILURE Discussion: Basically says to replace HCU first and then ECU if code still active. So, the dealer is aware of the issue and outright lied to me. There is also an active Class Action Lawsuit for this very issue In California Plantiff James Neu. The fact that my vehicle is not in a safe working condition with this faulty part. The fact that the Dealer is lying about which part is defective and would have installed a different part than what they said the problem is. It is very disturbing that an automotive company is treating the safety of their customers so carelessly. The Fact that this is a common and widespread issue and nothing is being done to rectify, appalling. Thousands of vehicles on the road, no parts available. Action needs to be taken. Lives will be lost, severe injury, it can happen to innocent people. Please do something

I have two warning messages appearing on my dash. Service Electronic Braking System and Service ABS System. Took it to my dealership Michiana Chrysler Dodge Jeep Ram FIAT in Mishawaka Indiana. I was informed that it needed an HCU (hydraulic control unit) and that the part was unavailable because of engineering review until at least August 2023. The work order was closed and i was sent on my way and told to check back at a later date for availability. After a little reading i found that this issue is under investigation and i wanted add my truck to your list of reports.

The ABS Brake control module malfunctioned causing several electrical issues. Fortunately the vehicle was able to function. RAM Service center noted a wait time of over 3 months. When I brought the vehicle to another Service center looking to see if the part was available, I was told to make an appointment and they charged me $90 to tell me what I told them. Uggg.
