RAM 3500, 4500, 5500 Recall for Engine Oil Film Defect

Plain-English summary

Chrysler (FCA US LLC) is recalling certain 2019-2020 Ram 3500, 4500, and 5500 cab chassis vehicles built with a Cummins 6.7L High Output engine. The recall addresses inadequate warmup protection, which can cause a lack of oil film on the engine connecting rod bearings while the engine is reaching operating temperature.

This defect can result in engine damage and connecting rod failure, which could potentially puncture the engine block. A damaged engine block may leak oil, which can contact hot engine or exhaust components, increasing the risk of a fire.

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 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
