The defect
Navistar, Inc. is recalling certain 2022-2023 IC EV school buses. The high voltage positive cables that connect the battery packs to the manual service disconnects (MSD) may have been mislabeled.

A misidentified electrical cable may be mistaken for a de-energized cable by a technician or first responder, increasing the risk of electrical shock and injury.
