What is wrong

Greenpower Motor Company Inc. (Greenpower) is recalling certain 2021 Nano Beast school buses. A control module interlock software error may allow the bus to move while the wheelchair lift is deployed.

The risk

The bus moving while the wheelchair lift is in use increases the risk of injury.

Why electrical defects matter: A short circuit is a fire risk and a module fault can switch off systems the driver depends on.

The remedy

Dealers will update the control module software, free of charge. Owner notification letters are expected to be mailed October 12, 2026. Owners may contact Greenpower's customer service at 1-909-346-1090. Greenpower's number for this recall is GP2604002.

About the electrical system

Electrical campaigns cover wiring, fuses, connectors, control modules, batteries and software across the vehicle.

What to do

  1. Enter your VIN in NHTSA’s lookup (below) to confirm that your vehicle is included and that the repair has not already been done.
  2. Call a dealer for the brand and book the repair. Quote NHTSA campaign 26V-643 and the manufacturer’s number GP2604002.
  3. If you notice burning smells, flickering power or warning lamps, have the vehicle checked before continuing to use it.
  4. Safety recall repairs are carried out free of charge by the manufacturer’s dealers. If you already paid for this repair yourself, ask the manufacturer about reimbursement and keep your receipt.

Check by VIN

A campaign rarely covers every vehicle of a model year. Enter your 17-character VIN to find the recall campaigns filed for your make, model and model year. The VIN is on the driver’s side of the dashboard (visible through the windshield), on the door-jamb label, and on your registration and insurance documents.

Is a recall still open on your vehicle? Only NHTSA’s official VIN check can say whether a campaign applies to your exact vehicle and whether the repair has already been done.

Your VIN is decoded with NHTSA’s public vPIC service to identify the make, model and year. It is not stored and is not added to any page address.
