Daimler Trucks North America LLC (DTNA) is recalling certain model year 2006-2015 Thomas Built Buses FS-65, Saf-T-Liner C2, Saf-T-Liner EF, Saf-T-Liner EFX, Saf-T-Liner HDX, and Minotour DRW school 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.
Consequence, in the NHTSA record
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.
Remedy, in the NHTSA record
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 onNovember 2, 2015. Owners may contact DTNA customer service at 1-800-745-8000. DTNA's number for this recall is FL-686.

Cummins will notify owners on behalf of DTNA, and dealers will secure the ends of the 90-degree elbow. In addition, the electronic control module (ECM) will be reprogrammed with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on June 12, 2015. Owners may contact DTNA customer service at 1-800-745-8000 or Cummins customer service at 1-800-343-7357.

Seat Belts
Defect, in the NHTSA record

When the button is pressed to release the seat belt, the latch plate can become partially engaged with the buckle, making the seat belt difficult to unlatch.
