What's wrong?
The International Thermal Research powered heater, listed as the ITR Fuel Heater or Oasis Heater, is installed on certain 2022-2023 Newmar Mountain Aire, Dutch Star, Essex, New Aire, Ventana, and Super Star motorhomes. Its fuel line carries diesel fuel to the heater so the heater receives fuel without leaking into the surrounding compartment.
On affected motorhomes, the heater has the wrong fuel line installed. That line can deteriorate and leak diesel fuel. A fuel leak near heater equipment raises the risk of a fire, especially if fuel reaches a hot surface or ignition source.
The warning signs listed for this recall are a diesel fuel smell or visible fuel around the heater or fuel line. If you smell diesel or see fuel, treat it as a sign that the line has begun to leak.
Who's affected?
Covers the 2022 and 2023 model years across Mountain Aire, Dutch Star, Essex, New Aire, Ventana, and Super Star, with the same ITR Fuel Heater/Oasis Heater parts tied to the equipment and diesel fuel-system components.
