Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Plain-English summary

Newmar Corporation is recalling certain 2017-2021 Mountain Aire, New Aire, Ventana, and Dutch Star vehicles equipped with certain Cummins diesel engines. The recalled vehicles are affected by a defect in the fuel rail assembly.

The sealing washer in the fuel rail assembly may not seat correctly in the pilot boreholes. When this occurs, the high-pressure fuel rail assembly can leak fuel. A fuel leak in the presence of an ignition source increases the risk of fire.

A total of 1,737 vehicles are affected by this recall. Owner notification letters were mailed on August 24, 2021. Cummins service centers will inspect the rail threads and fuel lines, and replace the rail as necessary, free of charge. Owners can contact Newmar customer service at 1-800-731-8300 or the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 for more information.
