On 9/30/2016, a thermal event occurred while the bus was in the shop for routine maintenance. As the bus was being moved (backed-out) of the service bay and smoke was seen escaping from the CNG tank storage compartment at the rear of the bus.

Damage was limited to the CNG fuel tank solenoid (melted) and the connecting harness (melted).
