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.
Risk: 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.
Fix: Dealers will reinstall the battery cables and replace the associated warning labels, free of charge. Interim owner notification letters were mailed January 13, 2023. Remedy parts are expected to become available in the 1st Quarter of 2023. Owners may contact Navistar's customer service at 1-800-448-7825. Navistar's number for this recall is 22523.
