What this recall means for you

Certain 2017-2021 Pierce Arrow XT, Enforcer, Impel, Quantum, Saber, and Velocity vehicles may have a sealing washer that does not seat correctly in the pilot bore holes of the high pressure fuel rail assembly. This can allow the fuel rail to leak diesel fuel.

A fuel leak in the presence of an ignition source increases the risk of a fire. Owners should watch for signs of a fuel leak and have the vehicle checked promptly.
