Defect. 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.

Risk. 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. In the event that cruise control cannot be disengaged while driving, owners should firmly and steadily apply the brakes and shift the transmission to neutral, placing the vehicle in park once it has stopped.

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.

Risk. 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.

Defect. 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.

Risk. 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.

Defect. Chrysler (FCA US LLC) is recalling various Dodge, Chrysler, and RAM vehicles equipped with Kidde Plastic-Handle or Push Button 'Pindicator' Fire Extinguishers. A list of the affected trailer models is available at: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17V824-0103.pdf. These extinguishers may become clogged, preventing the extinguisher from discharging as expected or requiring excessive force to activate the extinguisher.

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.

My ABS pump went out, causing my stability control to not function and cruise control to not function. Cruise control would randomly deactivate, causing a momentary loss of control and ABS function. Dash light illuminated with codes relating to ABS pump and traction control. ABS pump was replaced (part no. 68195569AB) and problem was fixed, but FCA will not reimburse me since I did the work myself.

The contact owns a 2018 Ram 5500. The contact stated that while driving at various speeds, the ABS and Traction Control Service warning lights illuminated. Additionally, the contact stated that the cruise control failed to operate once the warning lights were illuminated. The vehicle was taken to an independent mechanic where it was diagnosed with a defective ABS module. The contact was informed that the ABS module needed to be replaced. The mechanic called an unstated dealer and was informed that parts for the repair were unavailable and that there was no ETA on when parts would be available. The manufacturer was not notified of the failure. The failure mileage was approximately 93,000.

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.

The contact owns a 2018 Ram 5500. The contact stated that on several occasions while driving 60 MPH with the cruise control activated, the ABS warning light and the Traction Control Service message was displayed with an audible pinging sound intermittently. Additionally, after the message and audible ping, the cruise control message was displayed. The vehicle was taken to a dealer where it was diagnosed that the ABS/HCU module needed to be replaced. The vehicle was repaired but the failure reoccurred. The manufacturer was notified of the failure. The failure mileage was 11,870. The contact stated the dashboard alarm (ping) alerting the driver of loss of traction control on the dashboard pinged no less than 300 times in the 1168 mile trip.

The ABS/HCU module has experienced a premature failure which is a huge safety risk as it controls my vehicles' Anti-lock Braking System, Traction Control & Cruise Control systems. Since experiencing this failure, my vehicle has had numerous safety incidents where Braking would lockup, traction with the roadway is lost etc. Please initiate a recall for this issue for these generation of trucks so this safety issue can be addressed.

Twice in the past year I have experienced a loss of the ABS braking system. Warning messages appear to service the ABS braking system as well as a general braking system malfunction. This loss of ABS is intermittent. I have taken it to the dealer to have it fixed both times, and they have replace the hydraulic control unit and ABS module. Mechanic told me this is a very common problem with these trucks. I was put at risk by not having a functioning ABS.
