What is wrong

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.

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.

Remedy

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.

Recall number 10V468000 · Recall details

On August 29, 2011 ODI received a Vehicle Owner's Questionnaire (VOQ) from a Los Angeles school district indicating a 2003 Thomas Built Saf-T-Liner HDX compressed natural gas (CNG) school bus in their fleet had insufficient clearance between the CNG tank and mounting bracket resulting in damage to the outer tank wrapping.The Mathematical Analysis Division of the federal safety agency calculated that a sample size of thirty (30) buses would give a high confidence (90%) estimation of whether similar buses were experiencing tank abrasion.In the course of this investigation nearly 70 buses (over 300 tanks) were inspected; no tank other than the subject of the VOQ was found to have insufficient clearance.Busses manufactured before and after the subject vehicle were inspected.As a result of this investigation, Daimler Trucks North America (DTNA) developed an improved inspection procedure that addresses the concerns identified in the Los Angeles complaint.In early February 2012 DTNA will mail an owner letter along with the new inspection procedure.See the investigative file for copies of DTNA's bulletin and owner letter.This preliminary evaluation is closed.The closing of this investigation does not constitute a finding by the federal safety agency that no safety-related defect exists.The agency reserves the right to take further action if warranted by circumstances.The ODI report cited above can be reviewed at www-odi.the federal safety agency.dot.gov/owners/Searchreference under the following identification (ODI) number:10423400
