Vehicles Affected: Approximately 2,500 model-year 2018 Ram 4500 and 5500 chassis-cab trucks
The Problem: The primary and secondary brake hoses located between the brake master cylinder and the hydraulic control unit may have been manufactured without anti-corrosion plating on the ferrules, which can allow the ferrules to corrode. If the ferrules corrode, brake fluid could leak and cause loss of braking, increasing the risk of a crash.
The Fix: Dealers will inspect the brake hoses and replace them if necessary for free.
