What's wrong?
The odometer in a 2023 Gillig Low Floor diesel-hybrid transit bus is built into the driver's dash speedometer gauge. Its normal job is simple: record and show accumulated mileage so operators and maintenance teams know how far the bus has traveled. That mileage supports scheduled inspections, service intervals, and safety-related maintenance.
On affected buses, the dash speedometer gauge does not properly log mileage when the bus is operating in full EV mode with the diesel engine off, including low-speed Depot mode. The bus still runs, but the odometer reading on the dash does not increase during that operating mode. That creates an inaccurate mileage record and can delay maintenance that depends on mileage.
The operator can see the problem while driving in EV mode: the odometer shows no mileage accumulation. That is the warning sign before the maintenance record falls behind.

What's the safety risk?
A missing odometer reading can delay critical safety maintenance, impair safe operation, and increase the risk of a crash. If mileage does not accumulate during EV operation, schedule the recall repair soon and keep maintenance records current. Repair is free at any franchised Gillig dealer.
What should I do?
- Check your VIN to confirm your 2023 Gillig Low Floor is included in this recall.
- Contact a franchised Gillig dealer to schedule the free speedometer-gauge replacement that restores odometer mileage display in full EV mode.
- Call Gillig customer service at 1-800-735-1500 with questions, and reference recall number 24V921.
- Bring the owner letter to the appointment if your agency received one.
- Track maintenance mileage outside the bus odometer until the new gauge is installed, because the odometer reading can be missing in full EV mode.
What happens at the repair
At the dealer, a Gillig technician installs a new speedometer gauge so the odometer displays accumulated mileage during full electric vehicle mode. The replacement gauge, parts, and labor are free under recall 24V921. Out-of-pocket repairs already paid are handled through Gillig's warranty, not through a separate reimbursement program. Ask the service desk how warranty coverage applies if you have prior repair paperwork for the speedometer or odometer issue.
