As NHTSA's recall record states it for campaign 20V511000.
Defect description
Chrysler (FCA US LLC) is recalling certain 2019-2020 Ram 3500, 4500 and 5500 cab chassis built with a Cummins 6.7L High Output engine.

This can result in engine damage and connecting rod failure, which could potentially puncture the engine block.
Safety consequence

Manufacturer remedy
