RAM 3500 Recall 20V511: Engine May Lose Oil Film and Fail, Risking Fire

NHTSA campaign 20V511, reported August 27, 2020, 32,318 vehicles potentially affected.

What this recall means for you

Certain 2019 and 2020 Ram 3500, 4500 and 5500 cab chassis vehicles with the Cummins 6.7L High Output engine may not have adequate warm-up protection. While the engine is reaching operating temperature, the connecting rod bearings can lack a proper oil film. This can damage the engine and cause a connecting rod to fail, which could puncture the engine block.

A damaged block may leak oil onto hot engine or exhaust components, which increases the risk of a fire. If you own one of these vehicles, check your VIN for open recalls and contact Chrysler customer service at 1-800-853-1403 (recall number W57).

The remedy is free: an authorized dealer will flash the engine calibration software to improve warm-up protection. Chrysler will also notify owners directly.
