A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Blue Bird Body Company is recalling certain model year 2015\-2018 Vision School Buses manufactured from February 19, 2014, through March 3, 2017. The chassis mounted battery box support bracket\(s\) on certain Vision buses may develop cracks or fracture and could allow the battery box to separate from the chassis and fall. The design of the existing battery box support brackets may not be adequate in certain applications. If both the battery box support brackets were to completely fail and detach from the bus, it could become a road hazard increasing the risk of a crash. Buses should be corrected immediately according to the instructions for Recall R17YY. Dealers should inspect for loose or missing fasteners and cracks at the bolt holes and the bend radius. Repair according to the matrix in the instructions. Repairs include removing braces on all units, adding reinforcements or replacing front and rear brackets on some units with new higher strength steel, based on the matrix in the instructions. Parts are expected to be available the end of April, initially in limited quantities, at no cost to you.
