NHTSA recall campaign
20V511000
What was wrong
Defect
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. Inadequate warmup protection can cause a lack of oil film on the engine connecting rod bearings while the engine is reaching operating temperature. This can result in engine damage and connecting rod failure, which could potentially puncture the engine block.
Risk
A damaged engine block may leak oil, which can contact hot engine or exhaust components, increasing the risk of a fire.
Manufacturer remedy
Chrysler will notify owners, and dealers will flash the engine calibration software to enhance the engine warm up protection, free of charge. The recall began September 10, 2020. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is W57.
