How Ram schedules service: Oil Change Indicator

Ram trucks use the Oil Change Indicator system to signal oil service based on driving conditions. The Ram 1500 (HEMI 5.7L, eTorque mild-hybrid, EcoDiesel 3.0L) and Ram 2500/3500 (Cummins 6.7L turbo-diesel) have markedly different intervals — the schedule below covers Ram 1500 gas. Cummins-equipped HD trucks have separate oil, fuel filter, and DEF service requirements.

Campaign #21V398000 · 27/05/2021

Issue: 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.

Fix: Dealers will update the torque specification in the owner's manual and other published service documents. Dealers will also inspect the vehicle's wheel studs, replacing them if necessary, free of charge. Owner notification letters were mailed on November 30, 2021. Campaign Y36 owner notification letters were mailed on November 30, 2021. Campaign Y26 owner notification letters were mailed on December 1, 2021.

AIR BAGS:FRONTAL

Campaign #15V459000 · 22/07/2015

Issue: Chrysler (FCA US LLC) is recalling certain model year 2012-2014 Ram 1500, 2500, 3500, 4500, and 5500 trucks manufactured January 18, 2011, to October 7, 2014, and equipped with the Electronic Vehicle Information Center option. 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.

Fix: Chrysler will notify owners, and dealers will inspect, repair as necessary, and secure the steering wheel wiring harness. Additionally, protective caps will be added to the air bag retainer spring ends. These repairs will be done free of charge. The recall began on September 18, 2015.

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

Campaign #17V821000 · 20/12/2017

Issue: 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.

Campaign #17V824000 · 21/12/2017

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.

Risk: A failure of the tie rod assembly may result in a loss of steering control, increasing the risk of a crash.

Fix: Chrysler notified owners on January 16, 2014 that dealers would inspect vehicles and replace the steering linkage assembly, if necessary. On or about February 27, 2014, Chrysler ceased its recall remedy program due to parts quality concerns, and then re-initiated it on or about April 14, 2014. In July 2015, and under a consent order with NHTSA, the company agreed to offer owners three options for remedying their vehicles: perform the original remedy, offer to repurchase the vehicle at the fair market value plus 10%, or offer an additional incentive offer towards the purchase of a new Dodge, Jeep, Chrysler, or Fiat vehicle. Chrysler will notify owners of the new recall options in a letter expected to be mailed on August 31, 2015. Owners may contact Chrysler at 1-800-247-9753. Chrysler's recall campaign number is N49.

These Mopar canvas seat covers were sold through Chrysler dealerships beginning October 15, 2015. The seat covers can impede the deployment of the seat thorax airbags.

Risk: If the seat cover impedes the air bag deployment, the seat thorax air bags may not provide adequate protection in the event of a crash, increasing the risk of a injury.

Fix: Chrysler will notify owners to remove the front seat covers and return them for a full refund. The recall began on July 1, 2016. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is S30.
