Tiffin Motorhomes Allegro Bus and Phaeton recalled for fuel hose disconnection and leak risk
What this means
Fuel filter hoses in certain 2022–2025 Tiffin Allegro Bus and Phaeton motorhomes may separate from their fittings, causing fuel to leak. A fuel leak near an ignition source can create a fire risk, and a sudden engine stall can lead to a crash.

- Contact Tiffin customer service at 1-256-356-8661 to confirm if your vehicle is affected.
- Cummins dealers will replace the fuel hoses for free once your notification letter arrives (expected November 20, 2026).
