abs light and traction control light would come on intermittently while driving then stayed on causing cruise control to not work. been happening for over a year

- Glendale, OR, USA

Antilock braking system lights started coming on intermittently about 2 months ago. It would occur then stop for a few trips. It has progressed to a constant alert with a notice to have the ABS system serviced. The vehicle has less than 50,000 miles on it and is not used daily. It has been in the shop for over a week and they have not returned my calls as to the diagnosis. I have read that there have been alot of issues with this.

[XXX]. Location : somewhere in rural Pennsylvania. Incident ahead of me in heavy traffic. Applied brakes, more forcefully than usual. Immediately warning lights and audible alarm appeared on dash. -??Service ABS system-??. Was located in very rural area, no safe place to exit highway. At next exit, pulled off, brakes appeared to be functioning as normal. But dash warning lights proclaimed no ABS system and no traction control. Also lost function of cruise control and trailer brake control.. cautiously proceeded to destination. Relative had code reader - revealed code C0020-01 ABS Pump Motor Control. Investigation on internet revealed this is a very common problem among Ram 2500 trucks. Very expensive and not covered under warranty. I believe the NHTSA has received numerous reports from other Ram owners as to this problem. This situation is very unsafe with the loss of these very important safety features. Ram has refused to address this issue. I-??m reporting this today in hopes that this agency dedicated to Safety will address this in a very timely manner.

Hi, The ABS System shows Service Antilock Brake System at the display, It comes and go so I assume that it is an intermittent issue, it does stays for hours or days and go on ad off during the whole drive, definitely is an issue. It allow the brakes to preventing locket when brake on certain circumstances. Had an issue on a wet pavement and have to handle to avoid crash with other vehicle cause the tires got locket and the truck slipped on the pavement for a considerable amount of feet's. Dealer inspected and replaced the module under warranty when I bought the truck and told me that it has to be replaced again.

Traction control, electronic braking system and ABS warning lights flash and ding repeatedly with a warning message to service ABS system and Electronic braking system. Dealer and local shop cannot obtain parts. I need a safe truck for work.

My ABS light keeps coming on and off intermittently causing my cruise control to be interrupted and causing vehicle to slow down unintended in traffic. doesn't stay on and only comes on and off when it feels like it. This is dangerous and could cause my brakes to not work properly or have someone hit me from behind when cruise control kicks off at high speeds on the highway. This should be recalled.

HCU and ABS module brake failure causing the ABS and traction control warning lights and audible tone to intermittently go off. This also results in the cruise control failing to work. This is the second time of such occurrence. First at 3 years old and 30k miles and second at 6 years old and 50.5k miles.

The anti-locking braking and traction control warning lights flicker along with a beeping. This causes the cruise control to also disengage. This first occurred when the 2018 truck was slightly over 3 years old and with 30,000 miles. I had both the HCU and ABS module replaced and it stopped the issue for a few years and 20,000 miles longer. At 50,500 miles, it has again become an issue.

Abs and service electronic braking system warning lights continuously go on and off while driving truck

The Hydraulic Control Unit begins to malfunction presenting on the ECU as C0020-01 ABS Pump Motor Control-General Electrical Failure. This is fairly common in 4th generation 2500-3500 RAM trucks. The malfunction affects the ABS system, Traction Control system, and Adaptive Cruse Control system by deactivating them when the malfunction presents. This could cause the braking system and other systems to not perform in hard breaking/ emergency braking situations causing the operator to loose control of the vehicle. The Traction Control system and ABS system warning lights illuminate on the dash and the message of "service electronic braking system" is displayed on the HUD.

HCU for ABS has failed - Intermittently fails when in operation. Basically hit a bump in the road and it fails. Hit another bump and it "fixes itself". Then hit another bump and it fails. Lights up the ABS light, ESC light, brake light, esc. After some research, this seems to be a common issue on the 2018 Ram 2500's.

I have had the ABS system failure happen for the third time. the first was around 24000 miles about May of 2020, repaired at a Ram dealer in New Mexico, I believe they only replaced the ABS ECU. The second time was 43,298 miles [XXX] 2022, they replaced the HCU AT Walker Ram in Alexandria Louisiana. It has now failed again with 65,723 miles on [XXX]. Every time it has cause the truck to lose the Anti-lock braking ability, traction control, cruse control & ETC. I feel that Ram should do a recall and fix the issue with a upgraded parts that doesn't fail every 20k so miles and cause a safety risk.
