Defect
Chrysler (FCA US LLC) is recalling certain 2018 RAM 4500 and 5500 cab chassis trucks. 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.
Safety Risk
If the ferrules corrode, the brake fluid may leak and cause a loss of braking, increasing the risk of a crash.
