The truck ABS, traction control, and service electric brake lights and warnings have flashed and beeped on and off and on and off every few seconds. I took the truck to the dealer to be fixed under warranty. The dealer states it has a bad HCU and no longer has anti lock brakes however I can still drive the truck with all that distraction going on in the dash. The part is on back order and I won't have my truck repaired until February (2.5 months) This same part was also replaced a a little over year ago under warranty along with Abs sensors and wire harnesses. I have 2 friends with the same year trucks who also had to have the same repair done. …

My 2018 Ram 2500 has 85,000 miles currently. At about 80,000 miles I got the ABS and Traction control warning lights along with dash messages to check the ABS amd electronic braking systems. I am a heavy equipment mechanic and thus checked the systems myself with a scan tool and other test equipment. I found that the ABS module has an internal electrical failure resulting in power not being supplied to the ABS pump/electric motor. I have verified that the pump works and has about a 48ohm resistance. If supplied with 12v and ground to the motor it will come on. Circuit testing from the electrical plug to the contacts for the motor one pin has contact and the other is an open circuit. I also have one seized plunger in the hydraulic control unit that is actuator by the motors eccentric lobe on the output shaft. …
On 07/02/2022 I had my Dodge Ram 2500 serviced and assessed for Electronic Braking System Warning and Service Soon light on, by Farlow Automotive 500 S. Wickham Road, West Melbourne, FL 32904 [phone]. The issue was diagnosed and identified as a bad ABS Control Module as well as a bad ABS Hydraulic Unit. The parts were ordered and installed on 07/20/2022. Following the installation the same Electronic Braking System Warning and Service Soon light went on again. I brought the truck back to Farlow Automotive immediately after the new braking units were installed and it was diagnosed as a faulty ABS Control Module and ABS Hydraulic Unit from the manufacturer. It has been over 2 years since the faulty ABS control module and ABS hydraulic unit has been installed and we have not received appropriate replacement to remedy this important braking system malfunction. …

The ABS control module has begun failing sporadically while the vehicle is running. When this happens is disables the traction control system and the ABS system until the alarm clears, and if the vehicles cruise control is on, it immediately disengages. All of these symptoms deteriorate the safety margin of the vehicle, and cause mid-driving malfunctions that can be unpredictable. When the module is malfunctions both the ABS warning light and TCS warning light are illuminated and a text warning is displayed on the multifunction display of the gauge cluster. The contact found that the parts to rectify this issue are being rationed by Stellantis, leading to unacceptable lead times in simply procuring the parts. When added to the shop rates charged to fix this issue, the price of replacing this clearly defective component begins to total in the thousands of dollars. …
