Filed Dec 30, 2025 · Acceleration, Brakes · CA

ABS FAILURE, WHICH TURNS OFF TRACTION CONTROL AND CRUISE CONTROL. This is a known issue for the HCU to fail. How is this not a recall on 2016 but it is on 17 and 18. Same parts.... have replace front hubs with new ABS sensors and rear ABS sensors, still on. It has to be the HCU or the module.

My truck, like those of numerous other Ram owners, has a malfunctioning ABS Control Module. Because of this malfunction, the ABS and cruise control do not work. In turn, this places me and other owners of this vehicle in an unsafe situation in that lack of an operating ABS system is conducive to skidding and accidents. Some owners have even reported that they cannot drive their vehicles due to locked brakes which resulted from this malfunction. I have tried every source in existence in my efforts to find a replacement module, but I have been totally unsuccessful. I have been told by one of your Customer Service representatives that your Company is “…unable to maintain a complete inventory for an indefinite period of time and the lower the demand, the less likely it is we will have stocked parts. As such, the part you are requesting is no longer in our inventory.”

ABS system/ Traction control system/ 4wheel drive system/ cruise control. I had the ABS system repaired/replaced once this year already and now i need it done again. ABS failure makes the 4wheel drive system fail and it's winter time and i need 4 wheel drive for safety.

In March of 2022 my ABS/Traction Control light illuminated and returned a code of "Internal Electrical Failure". I have had this evaluated by two different dealers with two different pieces being blamed. One is the ABS Contril Module and the other is the Hydraulic Control Unit. I have replaced both multiple times without any remedy. The dealer stating that is was the ABS Control Module told me multiple times that they cannot even order the part to fix it. This means I cannot get a state inspection sticker on my primary mode of transportation as well as not having working ABS brakes, traction control, and cruise control. This is a concern with my family being safe as well as when towing my 5th wheel rv. There is an open investigation for 2017-2018 but my truck is a 2016 with the same issue. There are multiple people on forums with Rams other than the 2017-18 trucks with this same exact problem. A lot of us are using vehicles that are not able to be inspected with safety equipment not functioning correctly.
