    We purchased the vehicle as a back up for when my husbands every day work truck is in need of service. The truck is from 2018 and now has about 40,600 miles because it isn't used often. The truck would start flashing a light saying service anti-lock brake system sometimes during the time the light was flashing it felt like the brakes struggled a little. We have sent it in to get repaired and they quoted us over $1300 of repairs because it needs a an abs module and pump.

    Intermittent issues with the cruise control system and the ABS electronic braking system. The lights will flash on and off and the beeping is constant. If beating on the side of steering wheel will allow you to turn cruise control, then the ABS system will be okay for unknown reasons it will start flashing again and cancel the cruise control and the system will start flashing check the ABS electronic braking systems.

    Lights and chimes constantly signaling trouble with ABS/Traction Control system. OBD 2 indicates ABS Module failure but have read online it could also be HCU pump, a connection problem or a combination of issues. At this point the warning lights are on constantly while driving. No cruise control available. Talked to dealership and informed they are aware of the issue as it is wide spread with several models. Long back order and wait times for upgraded parts. Seems clear it is a safety issue.

    A diagnostic code has been displayed for the Anti-Lock Brake System - C0020-01 —> ABS Pump Motor Control - General Electrical Failure. Going over a bump in the road will cause the ABS system to deactivate the cruise control. The diagnostic code can be cleared and the cruise control will resume. Reading on RAM / Cummins online sites, many say that either the HCU and / or ABS Module needed to be replaced and many submitted reports to the NHTSA to start an investigation. No damage has been evidenced at any of the wheel sensors. With the ABS illuminated, it appears that the unit wouldn’t function if needed. The clearing of codes has been done numerous times. First noticed in about January 2024.

    We bought this truck from a dealer in March of 2023. We were never informed by the dealer that the truck had this issue. ABS light and traction control lights come on & stay on for periods of time. Sometimes lights come on & off repeatedly while driving along with chime on & off. When lights come on, there is no cruise control available to use. I took it to the dealer we purchased from over a year ago and was told there was no solution for the problem. They said it was under an engineering review. No parts were available for a fix. I have documentation from the previous owner that this was occurring when he owned it in April of 2022. Since we pull trailers with equipment and also a large fifth wheel camper, we feel very unsafe when the ABS braking system and the traction control goes out while driving this vehicle. It is available for inspection upon request. When will there be a repair for this?

    1. Serv anti-lock brake system,. 2. service electronic braking system. ABS light on and traction control light on. Diagnosed issue is Hydraulic control unit and possible module antilock brake system. Dealership does not have the parts for repair. Manufacturer refuses to put a recall notice even though several complaints have been issued by the RAM community.
