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!

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.

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 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 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.

Anti-Lock Braking system and Electronic Braking system, service system warning come on and off randomly all the time. When this happens, cruise control does not work. Had it replaced at the dealership once and It started doing the same thing. Took it back and they said they didn-??t know what was wrong with it And that they didn-??t want me thinking they didn-??t want to do warranty work. The warnings were coming on and off more frequent. Don-??t know what to do. Do you have any suggestions? This is a safety concern for me.

my 2018 Ram 3500 had less than 36,000 miles when the anti-lock brake system and service electronic brake system alarms began randomly flashing. this happens now every few seconds and so speed/cruise control no longer functions, also anti-lock and skid prevention has failed. Dealers have 3 month back order on the Hydraulic Control Unit, leaving owners the choice of operating an unsafe vehicle, or parking it for months.

Truck gets a service electronic braking check engine light and disables traction control as well as the cruise control. The braking becomes disabled at random times. Taken the unit to the dealership just to be told the part has been backordered for over 2 years and that they cannot sell me the HBU to repair it. They said they could remove the unit and have it shipped off to be remanufactured but my truck will be inop for min 2 weeks. Was told the part I needed 68143491AB

Dashboard ABS and Traction Control Lights come on intermittently with message to service breaking system. The lights are accompanied by loud audio alarms. The audio alarms usually cycle through a minimum of three times; sometime five. The dashboard ABS and Traction lights reset by themselves. Scanner codes identify an electrical problem with the ABS HCU and/or hydraulic pump. Dealership maintenance and service departments advise new parts are not available but to check back frequently for supply updates. If/when repair parts become available, this repair will be the second time I have endured this problem. Also, I have been able to reset the above dashboard alerts and audio alarms without the aid of Bidirectional scanner by cycling my windows down and up. So, I-??m not sure if I have an ABS/TC problem or a wiring problem.
