What's wrong?
In NHTSA campaign 23V532, the remote Stage 2 fuel filter hoses on 2023 Tiffin Phaeton motorhomes are part of the diesel fuel delivery system for the Cummins L9 engine. These hoses carry fuel through the filter path so the engine receives clean diesel while the fuel stays contained under normal operating conditions.
On affected Phaetons, Cummins says the fuel hoses were damaged during engine production when they snagged on a pallet on the assembly line. That damage was not noticed before the engines were installed in PowerGlide chassis motorhomes. A damaged hose can leak diesel fuel or disconnect, letting fuel escape from the system.
People in or around the motorhome can see smoke or other visible signs of a fuel leak. A diesel fuel smell is another warning sign. If either appears, the hose damage has already reached the point where the fuel system is not staying sealed.
