NHTSA campaign 21V506, reported July 2, 2021, 1,737 vehicles potentially affected.

What this recall means for you

Cummins service centers will inspect the fuel rail threads and fuel lines and replace the fuel rail as needed, at no cost to you. If you own a motorhome with a Cummins diesel engine covered by this recall, contact Newmar customer service at 1-800-731-8300 and reference Cummins 21E-32.
