Service bulletins for the 2020 Ram 3500

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NOTE: This may happen more as the vehicle ages, especially if the vehicle is used extensively for towing or hauling heavy loads. The cause of the concern may be due to degradation of the rear axle fluid. It is very important to follow the routine maintenance schedules on these vehicles when it comes to changing the rear axle fluid if the vehicle is used primarily for towing or hauling heavy loads. If you experience a vehicle with the above condition, please perform the proper maintenance procedures for the rear axle and replace the fluid first before replacing any hardware components. NOTE: This service bulletin is only applicable to vehicles that have no history of an axle fluid replacement. If the vehicle usage includes police, taxi, fleet, off-road or frequent trailer towing, regular axle fluid changes are required every 3 years or 30,000 miles (whichever comes first) per the Maintenance Schedule in the vehicle Owner's Manual. This bulletin involves changing the rear axle lube to possibly address a chatter, shudder or vibration."

When the vehicle is powered on, the diagnostic is enabled due to thawed DEF at the tank bottom surface, but the fluid in the center is still partially frozen. ● Not following the proper DEF fill procedure and overfilling the tank.** This bulletin involves replacing the urea delivery module and grade vent valve and updating the Dosing Control Unit (DCU) software."
