I am the second owner of this vehicle. Shortly after purchase (mileage 26,401) the Hydraulic Control Unit (Control for Anti-lock braking system) failed. Dodge dealer installed OEM replacement in March 2022. The same component (Hydraulic Control Unit (HCU)) failed again July 2023. Dodge dealer scheduled service/replacement for August 3, 2023. Upon delivery of vehicle for service I am told Chrysler has blocked dealers from ordering any HCU nor are they to use any current inventory on hand. Chrysler has initiated an "engineering investigation" into these parts and is seeking another manufacturer to supply going forward. Chrysler estimates a part may become available by February 2024. Vehicle is used for towing and has no anti-lock braking system in the mean time. I believe this could pose a safety issue.

My ABS control module was replaced 2 years ago by David Stanley Dodge in midwest city oklahoma. It is failing again and i have discovered a lot 2017 & 2018 ram 2500/3500 trucks are having the same issue. Last time it cost $800 to fix. I now have to take it back in again to have it fixed again. This is unacceptable. Ram should be recalling this issue on these trucks.

ABS System, Traction Control and Cruise Control. Issues with ABS system taking out the cruise control and cause vehicle speed to decrease with out control increasing risk of a rear end collision. The manufacturer is very aware of the problem and the control unit is on back order for about 9 months. This is an intermittent problem that some times does not occur during the course of a day and sometimes it will flash 100 times a day.

ABS warning has been going on and off for 2 years This is the same problem that the current class action lawsuits make reference to. I have had this problem for a long time and parts to repair it have not been available. Recently my wife ran into a bullard in a wet parking lot that she felt was a result of the antilock brake system. I only use the truck when it is absolutely necessary due to this problem. It scares me to think that I might not be able to stop this heavy vehicle. I hope this gets resolved soon.

Dealer says part is on back order for the next 9 Months so i must drive my truck without theses Safety systems until the part comes in.

While braking the ABS will not engage causing emergency braking to be much more difficult and dangerous. The ABS failure has been confirmed by my mechanic. My vehicle has not been inspected by the manufacturer, police or insurance reps. The problem was initially hidden by the dealership that sold me the truck. I don't know how they managed to do it, but the issue was not disclosed by them.
