The sealing washer may not seat correctly in the pilot boreholes, allowing the high-pressure fuel rail assembly to leak.
Possible consequence
A fuel leak in the presence of an ignition source increases the risk of a fire.
Remedy
Cummins service centers will inspect the rail threads and fuel lines, and replace the rail as necessary, free of charge. Owner notification letters were mailed on August 24, 2021. Owners may contact Newmar customer service at 1-800-731-8300. Newmar's number for this recall is Cummins 21E-32.
