I keep getting alarms on my truck for the ABS system and brake controlling system. I took the vehicle to a dealer to find out the problem and was told the HCU and the ABS module both need to be replaced and this is a common issue with my year and model truck. I was informed my repair bill would be over $1900. I tow a fifth wheel camper on a regular basis and do not want to have my brakes lock up while an 11,000 pound trailer is behind me.

Starting March of 2022 I began having intermittent alarms for the anti-lock brake system needing to be serviced. Often the alarm would come on and off going over small bumps in the road. With time the issue became worse and the alarm is on all the time. This affects the vehicles anti-lock brakes, electronic stability control, and the cruise control. I took my car to a mechanic and they found that both the hydraulic control unit and the anti-lock brake system module need to be replaced. Cost is over $2000, but feel I need to replace to have a safe vehicle as I often pull a trailer.

The truck consistently flashes a warning for -??Service Antilock Brake System-?? and a scanning tool provides the code C0020-01. The truck was evaluated at a local mechanic, who indicated the code represented a general ABS system failure. I have researched the issue and found that this problem is a common complaint with 2018 Ram 2500s.

In July, I drove over a bridge expander bump and now I am getting two errors: 1) Service anti-lock braking system with the ABS light on; 2) Service electronic brake system with the traction control light lit. The lights and notice come on then go off for a few minutes then back on again. This repeats until I turn the truck off and restart it. It then stopped for several months, but is now doing it again yesterday after driving over a very small bump in the road. My vehicle is available for inspection upon request. This problem puts me and my family at risk because the anti-lock braking system and traction control are deactivated during these incidents. I am not able to reproduce the problem at will, it happens randomly and intermittently. The vehicle has not been inspected yet. On-line research indicates many owners are having to replace ABS sensor and pump around the same amount of mileage as mine.

My ABS and traction control light intermittently blinks on and off. I took my vehicle to the dealership and was told this is a known issue. That I need a new ABS power module and controller. The parts are very expensive and on back order. I was informed to continue driving the vehicle until the parts are available.

The ABS and Traction Control lights constantly come on, even after replacement HCU and ABS parts are replaced. It-??s a once a year fix, and should be recalled. Once the lights come on, braking is affected, and cruise control no longer functions. I used a previous date, because I need to replace the parts again, for the third time. I have asked Ram support to just send me the parts, and I will do the repair, but unfortunately, they prefer that I continue to pay the dealer to repeat the same repair over and over.

The abs and traction control light are flashing on and off SEVERAL times especially when on a rough road. It kicks my cruise off and sometimes stays on which locks the diff and disengages any ABS functions resulting in the loss of braking performance and capability.

My ABS and traction control lights keep coming on intermittently with a message saying service electronic brake system and anti-lock braking system.

At approximately 30,000 miles the vehicle warning lights for "Service ABS" and "Service Electronic Brake System" began flashing intermittently. I took it to the local dealer and they replaced the Hydraulic Control Unit (HCU) on 5/12/2021. Approximately 2 months ago the exact same warning lights began flashing again so we took it back to the dealer yesterday 9/28/2023, 53,000 miles, and they diagnosed it as being the HCU and recommended that we do not drive the vehicle. They want to charge me for the exact same repairs that happened 23,000 miles ago. This issue is known but yet they will not fix this vital safety component of the vehicle. I cannot believe that a recall has not been initiated for this safety hazard.
