On certain vehicles equipped with Cummins ISL engines, the fuel filter shell and nut plate could separate, causing a fuel leak and also causing the engine to stall. Stalling would result in a loss of motive power, increasing the risk of a crash resulting in injury and/or damage to property. Correction: Cummins-authorized dealers will replace the fuel filter.
