The defect
Tiffin Motorhomes, Inc. (Tiffin) is recalling certain 2022-2025 Allegro Bus, and Phaeton motorhomes, equipped with certain L9 diesel engines, part number D563027BX03. The remote fuel filter hoses may separate from the fitting, causing a fuel leak and an engine stall.
The risk
A fuel leak in the presence of an ignition source increases the risk of a fire. An engine stall increases the risk of a crash.
The remedy
Cummins dealers will replace the fuel hoses, free of charge. Owner notification letters are expected to be mailed November 20, 2026. Owners may contact Tiffin customer service at 1-256-356-8661. Tiffin's number for this recall is TIF-150
A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
