Subject: Complaint Regarding Delayed Safety Recall Repair – 2018 Ram 5500 (Recall C4B / NHTSA Recall 24V-896) I own a 2018 Ram 5500 Chassis Cab, VIN [XXX]. My truck is subject to Safety Recall C4B (NHTSA 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 NHTSA 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 NHTSA 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 / NHTSA Recall 24V-896 Thank you for your attention to this matter.

Received notification of NHTSA Campaign Number: 24V896000 (Service Brakes, Hydraulic); however, the part to repair the recall is not available. The manufacturer has exceeded a reasonable amount of time for the recall repair. Because the vehicle currently has this recall, the State of CA will not allow the vehicle to be registered and is now out of operation. In addition, this vehicle is used for business and has resulted in several weeks being out of operation. ABS and traction control warning lights have illuminated while driving over uneven pavement. The vehicle is currently at the dealership and I was informed the manufacturer was not providing parts for the RAM 5500 series. The manufacturer was made aware of the issue and has confirmed that parts are NOT available for the RAM 5500 series.

The ABS module has failed. This has caused the service ABS light to come one, the service electronic braking system to come one, and the service electronic throttle control light to come on. The module according to Chrysler is part number 68347099AC which is unavailable at any dealer in the country. We have called many dealers and they have searched for the part to no avail. We have contact Mopar corporate and they told us there is no update on this part. We feel that operating the vehicle is unsafe but we don't know what to do without the part. Chrysler has offered no assistance. I have attached photos of the check engine lights as well as a photo from the scan tool showing the failure of the module - it cannot communicate.

ABS system lights flashing, and other alarms show up. Have been told by the dealer the ABS system will not work when lights are flashing, but standard braking will work. This affects the cruise control system and trailer brakes will not work when the system is flashing. Can not use this vehicle to pull my trailer. This is a true safety issue and is causing a loss of revenue. To just tell the public you don't when good parts will be available to fix the issue in not excusable. Dodge / Ram should have to buy the truck back if they can't fix it.

Chrysler (FCA US LLC) is recalling certain 2014-2018 Dodge Journey, Charger and Durango, RAM 2500, 3500, 3500 Cab Chassis (more than 10,000lb), 4500 Cab Chassis and 5500 Cab Chassis, Jeep Cherokee and Grand Cherokee and Chrysler 300, 2014-2019 RAM 1500, 2015-2018 Dodge Challenger, 2015-2017 Chrysler 200, 2016-2018 RAM 3500 Cab Chassis (less than 10,000 lb), 2017-2018 Chrysler Pacifica and 2018 Jeep Wrangler vehicles. These vehicles are being recalled to address a defect that could prevent the cruise control system from disengaging. If, when using cruise control, there is a short circuit within the vehicle's wiring, the driver may not be able to shut off the cruise control either by depressing the brake pedal or manually turning the system off once it has been engaged, resulting in either the vehicle maintaining its current speed or possibly accelerating.

Consequence & remedy

Consequence: If the vehicle maintains its speed or accelerates despite attempts to deactivate the cruise control, there would be an increased risk of a crash.

Remedy: Chrysler will notify owners, and dealers will inspect the software, and perform a software flash on the engine or powertrain control module, free of charge. The recall began June 4, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Note: Owners are advised to stop using cruise control until the software update has been performed.

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.

Consequence & remedy

Consequence: If the ferrules corrode, the brake fluid may leak and cause a loss of braking, increasing the risk of a crash.

Remedy: Chrysler will notify owners, and dealers will inspect the brake hoses and replace them if necessary, free of charge. The recall began June 19, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is U41.

18V100000 · Power Train:automatic Transmission

Feb 8, 2018

Chrysler (FCA US LLC) is recalling certain 2017-2018 RAM 1500, 2500, 3500, 3500 Cab Chassis, 4500 Cab Chassis, and 5500 Cab Chassis vehicles, all equipped with a column shifter. Pushing the brake pedal for prolonged periods when the vehicle is running and in PARK may cause the Brake Transmission Shift Interlock (BTSI) pin to stick in the open position. With the pin in the open position, the transmission can be shifted out of PARK into any gear without pushing the brake pedal or having the key in the ignition.

Consequence & remedy

Consequence: Being able to shift the transmission without pushing the brake pedal and/or without a key in the ignition can increase the risk of an unintended vehicle rollaway that may result in personal injury or a crash.

Remedy: Chrysler will notify owners and dealers will update the Body Control Module software. Dealers will also test the BTSI operation, replacing the solenoid as necessary. The recall began February 26, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is U11.

RQ25003 · Post Recall Remedy Brake Transmission Shift Interlock (btsi) Failure

Opened Jul 3, 2025 · No close date supplied

Status: open (inferred from source dates) · Power Train:automatic Transmission; Power Train:automatic Transmission:gear Position Indication (prndl)

The Office of Defects Investigation (ODI) has received 14 Vehicle Owner Questionnaire (VOQ) reports and 6 EWR Death & Injury (D&I) reports describing post recall remedy failures of the brake transmission shift interlock (BTSI) system in certain Model Year (MY) 2013-2018 RAM pickup trucks.The subject vehicle models include 1500, 2500, 3500, 4500, and 5500 trucks equipped with a column mounted shift lever.The failures of the BTSI described in the VOQs occurred on vehicles that had all previously been repaired under recall 17V-821 or 18V-100.Both recalls address a potential condition which can cause the BTSI locking pin to become stuck allowing the transmission to be shifted out of Park without depressing the brake pedal and/or without having a key in the ignition.Shifting the transmission out of Park when not having the brake pedal depressed can result in a vehicle rollaway. ODI is opening this Recall Query (RQ) to review the effectiveness of the 17V-821 and 18V-100 recall remedies, understand the root cause of additional vehicle rollaway incidents, and identify any other possible root cause that may affect the performance of the BTSI system. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.
