ABS and traction control module defect. Dealer says repair not a recall.

- New Iberia, LA, USA

-??Service ABS-?? and -??Service Electric Brake System-?? cautions alerts accompanied by warning chime, traction control and cruise control failures. Known issue with the Hydraulic Control Unit on this model. Dealer couldn't get parts as they were back ordered and now when available the price has tripled. Replacement parts seem to have the same issue. This started with about 25,000 miles on the vehicle.

Timely as my 2018 2500 seems affected. I've performed no troubleshooting but it is extremely intermittent, either the Service the ABS or Service the Electronic Braking System(s). Usually, a bump in the road makes it come and another turns it off. Sometimes it happens so quickly, only the message and traction control disabled light comes on, sometimes only the chime comes in. Sometimes the message stays up and the brake warning and traction control light comes on, sometimes for a few minutes, sometimes a couple of seconds. Always goes away with an ignition cycle. If it's on long enough. For some period of time, it came in when I turned the truck on and off when I released the parking brake. Annoying.

The ABS and Traction control system which is operated through the ABS Module intermittently goes on and off alerting the ABS and Traction control systems are not functional. This causes the Anti-lock braking system and Traction control system to no longer function limiting function under wet or slippery conditions. This puts me the driver and others at risk.

- Tacoma, WA, USA

The abs module has gave me issues and now has gone completely out causing no brakes and while it was having intermittent issues causes no cruise control and causes transmission issues which is another thing the transmission has went out again after this is the 3rd time replacing at around 10k everytime

Failure of abs / hec control module of abs /traction control system...part has been on order for over 2 plus years only 15 k miles and failed.This would result in accident of abs not working properly.

- Dayton, OH, USA

The warning lights for my ABS and traction control come on and off while driving normal driving conditions. Every time they flash it also has an audible ding that is very distracting. If I am using the cruise control when this happens the cruise control will turn off. The ABS system does not work when the lights come on. I am afraid I will be unable to stop. I took it to a local dealer and they confirmed that the HCU unit is defective and needs to be replaced at a price of $1300.

- Colfax , WI, USA

in 2022 the abs and traction control lights began to come on together, leading to loss of ABS and traction control in addition to not being able to use the cruise control. Vehicle was taken to the dealer to be serviced and they stated they would replace the HCU but would not replace the ABS module as they would only address one thing at a time. The problem continues to persist with the constant alarm ding and loss of abs and traction control as the lights continue to flash on the dash. This is a safety issue as you don't know when you'll have abs or traction control and if it happens while driving with the cruise control on, it abruptly shuts down the cruise control.

my family and I were on a trip out of town in the fall, this oct, when suddenly as we were braking and the trucks break system started flashing on and off saying service brakes failure antilock the bells kept chiming we were scared to death with bell chiming on and off and lights flashing on the dash we stopped along the side of a busy highway camper and all and go what is going on should we continue or make a call for help. I shut the engine off and started it back up and everything was fine. so we started down the road and it returned after a couple of miles so we did this over and over but finally it just kept dinging until we made it home now two weeks later have not driven the truck now two weeks later. found out that this truck has a history of this. by the way this truck only has 13000 miles on it not driven in winters and all highway use. yes but out of warranty with a dangerous breaking issue at again 13000 miles

ABS / TRACTION CONTROL dash light error. Light code C0020-01. ABS CONTROL MODULE.

- Camdenton, MO, USA

While driving the service ABS System/ Traction control dash warning message appears on the screen & chimes at the same time. The cruise control then shuts off. At first it was intermittent then it was almost all the time. With winter coming soon the ABS/Traction control will be much needed. After going online, it seems like this is a common problem with 2017-2018 Rams. After going to a Ram dealer in my area they replaced the HCU/ABS pump. I feel that if this is a common problem it should be addressed with a recall to avoid potential vehicle control problems

- Appleton, WI, USA

The ABS/Traction lights/Bell keeps alarming on my dash. The ABS HCU needs to be replaced. I have found out from research on line that RAM knows about this and chooses to do nothing about it. It mainly affects the 2017 and 2018 RAM 2500's. They switched manufactures for the ABS/HCU during those two years and the parts are inferior and constantly fail causing the ABS to be inoperable causing a serious safety concern.

ABS and traction control warning lamps and messages appear with chime on and off message Service brakes system needed ABS only 26,400 miles

- Marysville, WA, USA

Warning lights for ABS and traction control coming on with message to 'Service Electronic Braking System'. During this time the ABS does not work and cruise control stops working. Being a 2500 vehicle, it is commonly used for towing trailers as it has a towing capacity up to ~16K lbs. Suddenly not having ABS and traction control is dangerous. In July 2024 I was driving from Phoenix, AZ to East Texas with a ~10K lbs trailer and this issue suddenly started popping up. This is the first time I experienced this with this vehicle. I understand there is a known issue with the hydraulic control unit and the ABS modules for 2017-2018 2500 & 3500 models yet there has been no recall on these vehicles.

- Cushing, TX, USA

UNKNOWN Service electronic ABS system light intermittently comes on and off hundreds of times in a ten mile drive. I am reporting this due to finding out that this problem is affecting many many other 2018 Ram owners.

- Chillicothe , OH, USA

I am getting a warning saying to service the anti lock brakes and the traction control. I have had this same issue before and paid the dealership to fix it. Also when the warning appears the cruise control shuts off. I am concerned about the loss of control of the vehicle.
