Defect: Daimler Trucks North America, LLC (DTNA) is recalling certain 2011-2023 Thomas Built EFX and HDX school buses. The exterior roof panel was manufactured with insufficient joint strength. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 221, "School Bus Body Joint Strength."
Risk: A school bus exterior roof panel with insufficient joint strength may separate during a crash, increasing the risk of injury.
Fix: Dealers will add additional mechanical fasteners to secure the joints, free of charge. Owner notification letters were mailed June 2, 2023. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL957.

Defect: Daimler Trucks North America LLC (DTNA) is recalling certain model year 2006-2015 Thomas Built Buses Saf-T-Liner HDX, Saf-T-Liner EF, Saf-T-Liner EFX, and Minotour DRW transit buses manufactured January 3, 2006, to August 1, 2014, and equipped with certain Ricon model S2005, S2010, S5005, S5010, S5505, S5510 wheelchair lifts. The affected lifts are equipped with folding link arms that may have pivot holes that are too big, allowing the bearings to move out of position.
Risk: If the bearings move out of position, the stowed platform may have excessive movement resulting in failure of the platform mounting. This failure could cause the wheel chair lift platform to fall out of the vehicle when the doors are opened, increasing the risk of injury for the lift operator.
Fix: DTNA will notify owners, and dealers will inspect the link arms for damage or for displaced bearings. The platform will be inspected for cracks. Any damaged parts will be replaced, free of charge. The recall began on November 2, 2015. Owners may contact DTNA customer service at 1-800-745-8000. DTNA's number for this recall is FL-686.
