What the authority reported
Issue: On certain electric school buses, the bolts that secure the high-voltage battery may not have been tightened properly. As a result, the bolts could loosen or break and cause the high-voltage battery to separate from the bus. If this happens, there could be a loss of power to the wheels.
Safety Risk: A loss of power to the wheels could increase the risk of a crash. A bus that is disabled could result in a transfer of passengers in an uncontrolled environment, which may create a risk of injury. Additionally, a high-voltage battery that detaches from the bus could create a road hazard for others and increase the risk of a crash.
Corrective Actions: Blue Bird will notify owners by mail and provide you with instructions for how to inspect and, if necessary, tighten or replace the mounting bolts for the high-voltage battery. The service manual will also be updated to specify how to properly tighten the bolts and the recommended service for them.
What to do
Follow the instructions in the official notice — recall remedies (refund, repair, replacement, or disposal) are defined by the issuing authority and the responsible business, and they differ per recall. Do not rely on summaries, including this one.
