- 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.
- What it can cause
- 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.
- What the dealer does
- 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
The repair is free, whatever the age or mileage of the vehicle, and whether or not you are the original owner.
Which vehicles
A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup.
| Vehicle | Model years | Safety record |
|---|---|---|
| Tiffin Allegro Bus | 2022 to 2025 | Not published here |
| Tiffin Phaeton | 2022 to 2025 | Not published here |
How this campaign compares
At 177 vehicles this is a small campaign: 62% of the 19,886 vehicle recalls with a published size filed from 1995 up to this one are as large or larger. The middle campaign among them covers 472. It covers model years 2022 to 2025, so the oldest vehicles on it were 4 model years old when the defect was reported to NHTSA.
Tiffin vehicles have been recalled over the fuel system, diesel 4 times before this, most recently in May 2026 as 26V338000. That is not evidence the earlier repair failed.
This site holds the complaint record for 1 of the 8 model years the campaign names. Their owners have filed 6 complaints with NHTSA, 6 of them before this campaign was filed. The earliest of them reached NHTSA in November 2021, 4 years before this filing.
The vehicles on this campaign carry 11 other recalls published here, the newest being: 24V566000 (electrical system), 24V036000 (seats), 23V643000 (equipment), 23V532000 (fuel system, diesel).
Check your own car
A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
Filed by Tiffin Motorhomes, Inc. with NHTSA on October 8, 2026 as campaign 26V662000. Every word of the defect, consequence and remedy above is NHTSA's published record of that filing, not a summary of it.
