The defect
Forest River, Inc. (Forest River) is recalling certain 2020-2021 Dynamax Isata vehicles. 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.
The risk
A damaged engine block may leak oil, which can contact hot engine or exhaust components, increasing the risk of a fire.
