Recall 24V027 affects 20 2024 Ic Bus Evsb school buses for mislabeled high-voltage cables. Repair is free at any franchised Ic Bus dealer.
Ic Bus is recalling 20 2024 Evsb school buses because high-voltage positive cables between the battery packs and manual service disconnects have the wrong labels. A technician or first responder can mistake a live cable for a de-energized one, which raises the risk of electrical shock and injury; Ic Bus dealers will complete the free recall repair.

What's wrong?
The high voltage positive cables on the 2024 Ic Bus Evsb school bus carry battery power from the battery packs to the manual service disconnects. Those disconnects are service points used to isolate high voltage power during repair work. The cables need the correct white high voltage identification tape so technicians can identify the positive high voltage cable path.
On affected buses, some battery cable kits were not reworked correctly after the earlier cable marking issue. Some cables still had blue tape, and some had no identification tape at all. That means the cable is part of the high voltage system, but the marking on the cable does not match the required identification.
An owner or driver is not expected to spot this during normal use. The issue is in the cable labeling inside the high voltage battery system, not in a dashboard message or drivability symptom. There is no warning sign before failure.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific bus is included in this recall.
What's the safety risk?
The mislabeled high voltage cable can be confused with a de-energized cable during service or emergency response. That creates an electrical shock and injury risk for a technician or first responder. There is no driver warning sign for this labeling problem. Repair is free at any franchised Ic Bus dealer.
What should I do?
- Check your VIN to confirm your 2024 Ic Bus Evsb is included in this recall.
- Contact a franchised Ic Bus dealer to schedule the free high-voltage cable inspection and relabeling so technicians and first responders do not mistake an energized cable for a de-energized one.
- Bring the recall notice if Ic Bus has mailed one. If not, reference recall number 24V027 when you call.
- Warn technicians and first responders before they work near the high-voltage battery cables until the dealer inspection is complete.
What happens at the repair
At the dealer, an Ic Bus technician inspects the high voltage cables that connect the battery packs to the manual service disconnects. If the positive cables need corrected identification, the technician adds white high voltage tape. The inspection and any needed tape work are free under the recall. Navistar's standard reimbursement plan applies for qualifying repairs paid before the owner notification. Follow the reimbursement instructions included in the customer notification, and bring prior repair paperwork to the service desk if you already paid for related cable work.

Frequently asked questions
What is recall 24V027?
Recall 24V027 covers 20 2024 Ic Bus Evsb school buses with high voltage positive cables that connect the battery packs to the manual service disconnects. The cables were mislabeled, which can lead a technician or first responder to mistake an energized cable for a de-energized one, increasing shock and injury risk.
What should I do if my 2024 Ic Bus Evsb is on this recall?
Check your VIN to confirm your specific school bus is included in recall 24V027. If it is, contact a franchised Ic Bus dealer to schedule the high voltage cable inspection. The dealer will add white high voltage tape where needed, and the repair is free.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to repair safety defects at no cost. Ic Bus dealers will inspect the high voltage cables and add white high voltage tape as needed free of charge under Navistar recall number 24502.
What is the safety risk?
The risk is electrical shock and injury during service or emergency response. A mislabeled high voltage cable can be mistaken for a de-energized cable, so owners and fleet staff should keep untrained personnel away from high voltage cable work and have the dealer complete the inspection.
When were owners notified?
Navistar mailed owner notification letters on February 5, 2024. If you manage a 2024 Ic Bus Evsb and never received the letter, check your VIN, then call an Ic Bus dealer and reference recall 24V027 or Navistar recall number 24502.
