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.

Issue: Chrysler (FCA US LLC) is recalling certain RAM ProMaster Trailer Light Modules, part number 68229650AB. These accessory modules were sold for installation on RAM ProMaster and ProMaster City vehicles. The Trailer Tow Lighting Control Module may have a software error on the affected vehicles and can prevent illumination of the trailer brake lights during brake actuation. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Assoc. Equipment."
Risk: Trailer brake lights that are inoperative can increase the risk of a crash.
Fix: Chrysler will mail letters to owners to try to notify the purchasers of the modules, and dealers will replace the Trailer Tow Light Control Modules, free of charge. The recall began on June 20, 2016. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is S29.

Issue: 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.
Fix: Chrysler will notify owners instructing them to contact Kidde for a replacement fire extinguisher, free of charge. The recall began February 14, 2018. Owners may contact Chrysler customer service at 1-800-853-1403 or Kidde customer service service toll-free at 1-855-262-3540, or online at www.kidde.com and click on "Product Safety Recall" for more information.

Issue: Chrysler (FCA US LLC) is recalling certain 2015-2017 RAM ProMaster City vehicles. These vehicles have incorrect information on the tire placard including incorrect vehicle capacity weight, total number of occupants, tire pressure and/or "None" designation for the spare tire size when a full size spare tire is present. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 110, "Tire Selection and Rims."
Risk: The incorrect tire placard can cause the operator to exceed the vehicle's weight capacity, or inflate the tires to an incorrect pressure, affecting vehicle handling, which can increase the risk of a crash.
Fix: Chrysler will notify owners, and dealers will replace the incorrect tire placard with a corrected one, free of charge. The recall began November 17, 2017. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is T62.
