In response, Newmar Corporation is issuing recall NHTSA # 21V 506 and TC # 2021-427. On certain motorhomes, as described in Cummins recall 21E-032, the fuel rail assembly on the engine may develop leaks, which may result in an undetected prolonged diesel fuel spray. A leak involving spraying/misting fuel in the presence of an ignition source may increase the risk of fire.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10202750-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10202750-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10202750","components":[{"id":"engine","name":"Engine","parent":null},{"id":"fuel-system","name":"Fuel system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"NEWMAR","model":"DUTCH STAR","year_from":2017,"year_to":2021,"match":null,"vehicle_ids":[]},{"make":"NEWMAR","model":"MOUNTAIN AIRE","year_from":2017,"year_to":2019,"match":null,"vehicle_ids":[]},{"make":"NEWMAR","model":"NEW AIRE","year_from":2020,"year_to":2021,"match":null,"vehicle_ids":[]},{"make":"NEWMAR","model":"VENTANA","year_from":2017,"year_to":2021,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
