Chrysler (FCA US, LLC) is recalling certain 2012-2021 RAM 3500, 3500 Cab Chassis, 4500 Cab Chassis, and 5500 Cab Chassis vehicles. Incorrect information in the Service and Owner's Manuals may cause the flanged lug nuts to be over-tightened, which could result in a broken wheel stud and possible wheel separation.
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.
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. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable.

Chrysler (FCA US LLC) is recalling certain 2016-2017 Ram 3500 Cab Chassis with a Gross Vehicle Weight Rating (GVWR) of less than 10,000 lbs, 2011-2017 Ram 3500, 4500 and 5500 Cab Chassis vehicles, 2009-2017 Ram 1500 and 2010-2017 Ram 2500 and 3500 pickup trucks, 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.
