2012 RAM 4500

WHEELS:LUGS/NUTS/BOLTS/STUDS

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.

Risk: Wheel separation can cause a vehicle crash.

POWER TRAIN:AUTOMATIC TRANSMISSION:LEVER AND LINKAGE:COLUMN SHIFT

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.

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.

EQUIPMENT

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. For a full list of the affected fire extinguisher models visit: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17E062-5427.pdf

Risk: If the fire extinguisher does not function properly, it can increase the risk of injury in the event of a fire.

The affected vehicles have a steering wheel wiring harness that may rub against the driver air bag module retainer spring.

Risk: This abrasion may result in an electrical short that could cause driver's frontal air bag to unexpectedly deploy. Inadvertent deployment of the air bag may increase the risk of injury and the possibility of a vehicle crash.

ENGINE AND ENGINE COOLING:ENGINE:DIESEL

Chrysler Group LLC (Chrysler) is recalling certain model year 2010-2014 Ram 2500, 3500, 4500, and 5500 trucks manufactured March 27, 2009, to September 5, 2013. In the affected vehicles, the electrical connectors of the diesel fuel heater may overheat.
