# 21V-506 recall: Newmar

These are official NHTSA recalls. A model year on a campaign is not proof a VIN is included. Owner reports are not included.

**Campaign:** 21V-506
**Manufacturer:** Newmar Corporation
**Component:** FUEL SYSTEM, DIESEL:FUEL INJECTION SYSTEM:FUEL RAIL
**Filed:** July 2, 2021
**NHTSA:** https://www.nhtsa.gov/recalls?nhtsaId=21V506

## The problem

Newmar Corporation (Newmar) is recalling certain 2019 Mountain Aire, 2020-2021 New Aire, 2020-2022 Super Star, 2018-2021 Ventana, and Dutch Star vehicles equipped 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.

## The safety risk

A fuel leak in the presence of an ignition source increases the risk of a fire.

## The 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.
