Gillig is recalling 592 2014-2021 Low Floor transit buses because rear-mounted ultracapacitors can let the engine start even when the master battery disconnect switch is off. Unexpected engine startup raises the risk of injury near the engine compartment during maintenance, and Gillig dealers will complete the recall repair free of charge.

What's wrong?
The rear-mounted ultracapacitor on affected 2014-2021 Gillig Low Floor buses is an auxiliary energy supply for the electrical system. It stores electrical power and supports the bus when power demand changes, separate from the main battery disconnect switch that maintenance staff use to shut the bus down.
On these buses, the ultracapacitor controls were not designed to detect when the master battery disconnect switch is in the "OFF" position. Because of that, stored power from the rear chassis-mounted ultracapacitor can still allow the engine to start and run for several minutes, until that stored power is drained. The repair path differs by system: the Vanner setup uses updated software, and the KBI setup uses a hard rewire.
The filing does not describe a dashboard warning or sound that alerts staff to this condition. Before engine compartment work begins, personnel are instructed to put the rear run box ignition select switch in "OFF," attach a "Do Not Operate" tag to the start switches and controls, and confirm personnel are safely clear before the engine is started.

What should I do?

- Call Gillig customer service at 1-510-264-5073 with questions about scheduling or bus configuration.
What happens at the repair
At the dealer, a Gillig technician updates the software on buses equipped with the Vanner Ultracapacitor system. For buses equipped with the KBI system, the technician completes a hard rewire so the disconnect system works as intended. The recall repair is available now, and parts and labor are covered. If you paid out of pocket before the owner notification for the same issue, Gillig reimburses those repair costs. Keep the repair paperwork and ask Gillig customer service or the dealer how to submit the claim.
