Thomas Built Buses recall: Power train
What is wrong
Daimler Trucks North America LLC (DTNA) is recalling certain 2018-2020 Thomas Built Saf-T-Liner HDX school buses equipped with Detroit DD8 Engines and Allison Transmissions. The Flex-Plate/Torque Converter fasteners may have been insufficiently tightened.
What could happen
The loose bolts can become lodged in the starter, disabling the bus, resulting in an evacuation in an uncontrolled traffic situation, increasing the risk of an injury.
The fix
DTNA will notify owners, and dealers will inspect and tighten the fasteners, as necessary, free of charge. DTNA issued owners an interim notification on December 13, 2019. The recall began August 7, 2020. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL-839.
