What's wrong?
The instrument panel in 2023-2024 Nova Bus Lfs Artic and Lfs buses is the driver's display for speed and warning lights. It is supposed to show vehicle speed and tell the driver when a system needs attention. The panel depends on firmware, which is embedded software that tells the display how to read and show vehicle information.
On affected buses, the instrument panel has the wrong firmware version. That software error can make the speedometer disappear or show warning lights incorrectly. The same firmware defect can also cause a loss of drive power, so the bus can stop responding as expected while in service.
There is no warning sign before failure. The first sign can be the missing speedometer, warning lights that do not match the vehicle condition, or an unexpected loss of drive power.
Who's affected?
Covers both Lfs Artic and Lfs buses across the 2023 and 2024 model years, all using the same instrument panel.

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 instrument panel stops showing the speedometer or warning lights, the driver loses information needed to judge speed and respond to vehicle problems. Loss of drive power also increases crash risk, and there is no warning before it happens. Schedule the firmware update soon. Repair is free at any franchised Nova Bus dealer.
What should I do?
- Check your VIN to confirm your 2023-2024 Nova Bus Lfs Artic or Lfs is included in this recall.
- Contact a franchised Nova Bus dealer to schedule the free instrument-panel firmware update that fixes the speedometer, warning-light, and drive-power defect.
- Bring the recall notice if Nova Bus mailed one. If not, reference recall number 24V648 when you call.
- Keep the bus out of service and call the dealer if the speedometer disappears, warning lights display incorrectly, or drive power drops before the repair.
What happens at the repair
At the dealer, a Nova Bus technician updates the instrument panel firmware with corrected software. The software update is free under the recall, and the service cost is covered. Nova Bus used its standard reimbursement plan for this campaign. If you've already paid for a related instrument-panel firmware repair, ask Nova Bus customer service or the dealer service desk how to submit documentation for reimbursement.
