It covers certain 2017–2018 Ram 2500 and 3500 pickups, 3500 cab chassis, and 4500 and 5500 cab chassis trucks. It addresses failures in the hydraulic control unit (HCU) that affect ABS, electronic stability control and traction control. Parts shortages are widespread. Many 2017 owners have reported to the federal safety agency that they got the recall notice but the repair part wasn’t available yet, and the manufacturer confirmed it was backordered. the truck cant be used due to the speedometer not working and the trailer breaks not working. the dealer confirmed that the abs module has failed and i cant use my truck and its been backordered for several years. this is completely unacceptable.

Subject: Complaint Regarding Delayed Safety Recall Repair – 2018 Ram 5500 (Recall C4B / the federal safety agency Recall 24V‑896) I own a 2018 Ram 5500 Chassis Cab, VIN [XXX]. My truck is subject to Safety Recall C4B (the federal safety agency Recall 24V‑896) involving the ABS Hydraulic Control Unit (HCU). I have attempted to have this safety recall completed, but the repair has been delayed because the required replacement part has reportedly been unavailable. This is a federally mandated safety recall involving the vehicle’s braking system. I am concerned that I have been unable to obtain the required repair within a reasonable period of time. The continued delay creates uncertainty about the safe operation of my vehicle and prevents me from having the recall corrected as required. I request that the federal safety agency investigate the availability of recall parts and the length of time owners are being required to wait for completion of this safety recall. I also request that the federal safety agency review whether the manufacturer is meeting its obligations to provide a timely remedy for affected vehicles. Vehicle Information: * Year: 2018 * Make: Ram * Model: 5500 Chassis Cab * VIN: [XXX] * Recall: C4B / the federal safety agency Recall 24V‑896 Thank you for your attention to this matter.
