The defect
Nova Bus (Nova) is recalling certain 2016 LFS and LFS Artic buses equipped with specific Allison Transmission drive units. The pressure switches on these Drive Units may fail, possibly resulting in a loss of drive.
The risk
A loss of drive can disable the vehicle unexpectedly, increasing the risk of a crash. Additionally, offloading passengers to transfer them to another bus can increase the risk of injury.
