I have a 2017 Ram 3500 and continue to have problems with the ABS brake system. At 17036 miles on 10-08-2020 I had an ABS failure warning light. The Ram Dealer replaced the HCU module which seemed to fix the ABS failure for a short time. At 35832 miles in November of 2023 I am once again getting a ABS warning light. The Ram Dealer now recommends replacing the ABS module and the ABS Pump. ABS failure should not be happening repeatedly on a low mileage vehicle.

Like many others, I am experiencing the Service ABS light coming on which not only disables the ABS system but also disables the cruise control. The chiming of the warning goes off every few seconds and can be extremely distracting. With the ABS no longer working, I and my family are at risk since we use this to tow a 14,000 lb. fifth wheel. I have taken this to a Ram dealer and the diagnostic is the ABS Module / Hydraulic control unit failure. Ram has known this is an issues for several years.

While driving the vehicles message display center says "service emergency braking system", the traction control indication light turns on and off, the abs indicator light turns on and off, the park sense indicators turn on and off, and if cruise control is on it is deactivated and turns on and off. An audible chime indication is also sounded when the message center displays a message. With the traction control and abs turning on and off creates an extreme safety problem especially with the winter months ahead. The vehicle has not yet been looked at by a anyone but an appointment has been made with the local dealership. This first started while driving on 11/11/2023. However, the indicator lights and chime still occur while the vehicle is in park and motor running.

C0020-01 ABS Pump Motor Control - General Electrical Failure

When I hit a bump my ABS warning light and my traction control light come on on the dash. My cruise control stops working. Had it scanned and there is an error code C0020-01-ABS PUMP MOTOR CONTROL - motor pump (open recirculation test). - internal electronic failure. It comes on and off more often when hitting a bump. This is apparently common and should be a recall.

Everytime the truck is driven I hear an audible chime multiple times over the trip with corresponding ABS and Traction control lights that say the systems aren't functioning. Multiple times I have experienced full lock up of all wheels while on snowy or wet roads. The chimes and flashing lights always come and go while rarely staying illuminated for more than 5 minutes, however at times will flash upwards of 15 times in a minute. Cruise control is non operational while the lights are on. This problem has been occurring for several years and best I can recall started shortly after 20 thousand miles.

On 32600miles abs and traction control start glitching. Happened to me on the highway pulling a rv and using cruise control, all of the sudden I lost cruise control on 70 mph and ABS with traction lights came on and off several times and end up go away, I stopped in the safe area and check all related parts on the vehicle that related brakes and abs, fluid was up to level all parts, brakes, wiring was good where I was able to see. After I continued to drive, abs did same thing several times, end up abs and traction lights came on and stayed for a while and all of the sudden for no reason came off for several miles. Sims like bad connection or abs module failure.
