Newmar Corporation is recalling 217 model year 2019 Mountain Aire, model year 2020-2021 New Aire, model year 2020-2022 Super Star and model year 2018-2021 Ventana & Dutch Star vehicles with certain Cummins diesel engines.
The sealing washer may not seat correctly in the pilot boreholes, allowing the high-pressure fuel rail assembly to leak.
A fuel leak in the presence of an ignition source increases the risk of a fire.
What to do
Cummins service centers will inspect the rail threads and fuel lines, and replace the rail -- as necessary -- free of charge.
Owner notification letters are expected to be mailed August 31, 2021.
Owners may contact Newmar customer service at (800) 731-8300. Newmar's number for this recall is Cummins 21E-32.
