Diamler Trucks has announced that it is recalling certain models of the 2011 through 2013 Thomas Built SAF-T-Liner School Buses built on a Freightliner custom chassis B2 chassis from November 15, 2010 through October 6, 2011. They stated that the grid heater ground wire may contact the relay power terminal and rub and chafe potentially resulting in a short circuit.
An electrical fault or short circuit may result in a fire. Diamler Trucks will notify owners, and dealers will inspect to ensure the grid heater relay ground wire is correctly routed and modified as required to ensure adequate clearance with the power terminal. The repairs will be preformed by Diamler truck dealers free of charge. The safety recall is expected to start on February 1 2012. Owners may contact Diamler Trucks at 1-800-547-0712.
