Defect
The hybrid battery tray on large touring hybrid buses has insufficient corrosion resistance. During service, the tray may corrode and develop holes, allowing water to enter the tray interior and contact the battery wiring connections. This may cause a short circuit and result in a vehicle fire.
Corrective action
All vehicles receive the following corrective actions. Because corrected parts require time to prepare, interim measures (items 2 and 3 below) are performed immediately, with the permanent fix applied once parts are available. 1. A floor panel is added to the bottom of the tray, and a seal and water shield are added to the lid. 2. The tray is inspected and replaced with a new unit if damage is found. 3. The wiring connections are inspected and replaced with new components if damage is found.
