— A Ram hydraulic control unit (HCU) recall involves more than 317,000 trucks with anti-lock brake systems (ABS), electronic stability control (ESC) systems and traction control systems that may fail.
The Ram HCU recall includes these trucks:
- 2017-2018 Ram 2500 Pickup

- 2017-2018 Ram 3500 Chassis Cab

The National Highway Traffic Safety Administration opened a federal Ram truck braking investigation in November 2022 following problems with the hydraulic control units and anti-lock brake systems. Chrysler was asked to provide information about 2017-2018 Ram 2500 and 3500 trucks.
Then in October 2024, Fiat Chrysler opened its own investigation into 2017-2018 Ram 2500, 3500, 4500 and 5500 trucks built with hydraulic control unit anti-lock brake systems that were failing.
