Recall 24V068 covers 5,197 2021-2024 Blue Bird Vision School Bus vehicles for warning lights and stop arms that deactivate. Free update at franchised Blue Bird dealers.
Blue Bird is recalling 5,197 2021-2024 Vision School Bus vehicles under recall 24V068 because multiplex module firmware can shut off the warning lights and retract the stop arm without warning. That failure can remove the bus's active stop signal during use and increase the risk of a crash or injury, and Blue Bird dealers will complete the repair free of charge.

What's wrong?
On a 2021-2024 Blue Bird Vision School Bus, the multiplex module is an electrical controller that manages commands from switches inside the bus. When the driver starts a loading or unloading stop, the module keeps the warning-light sequence and stop arm action moving after the driver uses the momentary switch. That control matters because the amber lights, red lights, and stop arm tell nearby traffic that children are boarding or leaving the bus.
The problem is firmware inside certain Ametek multiplex modules. The software can make the module reset while the bus is operating. That reset does not shut down the bus's primary driving systems, but it erases the saved command sequence. If the reset happens after the warning-light sequence starts, the lights turn off and the stop arm retracts before the sequence is complete.
There is no audible or visual warning before the module reset. The driver is not given a separate alert that the warning lights have deactivated or that the stop arm has retracted.
Who's affected?
Covers four Vision School Bus model years, all tied to the same electrical system software.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
If the warning lights turn off and the stop arm retracts during use, nearby drivers lose the intended stop signal, increasing the risk of a crash or injury. There is no audible or visual warning before the event, so schedule the firmware update soon. Repair is free at any franchised Blue Bird dealer.
What should I do?
- Check your VIN to confirm your 2021-2024 Blue Bird Vision School Bus is included in this recall.
- Contact a franchised Blue Bird dealer to schedule the free multiplex-firmware update that fixes the warning-light and stop-arm failure.
- Bring the recall notice if Blue Bird mailed one. If not, reference recall number 24V068 and Blue Bird recall R24CX (SB) when you call.
- Use extra caution during student loading and unloading until the repair is complete; the warning lights and stop arm can deactivate without warning.
What happens at the repair
At the dealer, a Blue Bird technician updates the multiplex firmware so the module handles the bus warning lights and stop arm correctly. The software update is free under the recall, with parts and labor covered at the dealer. Blue Bird's general reimbursement plan is on file for owners who paid for the same repair before the recall notice. If you have prior repair paperwork, contact Blue Bird customer service and ask how to submit documentation under that plan.
