NHTSA's recall notice
As NHTSA's recall record states it for campaign 12V526000.
Defect description
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.
Safety consequence
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.
Manufacturer remedy
Tiffin Motorhomes will notify owners, and dealers will install a heat shield, free of charge. The safety recall began on November 14, 2012. Owners may contact Tiffin at 1-256-356-8661.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
