The defect
Tiffin Motorhomes is recalling certain model year 2010-2013 Allegro Bus motorcoaches, manufactured from March 2010, through September 2012 and equipped with a Cummins EPA 2010 ISL engine. Insufficient shielding between the exhaust pipe and floor may cause possible overheating of the floor above the engine compartment.
The risk
If the exhaust pipe in the engine compartment were to fail, the escaping exhaust gases could make the floor area above the engine extremely hot, increasing the risk of personal injury or possibly resulting in a fire.
