Chronology :

On April 13 2023 during manufacturing, an incomplete vehicle experienced an electrical failure in the fuse box mounted underneath the driver’s platform.

Between April 14 and April 22, GILLIG conducted an internal analysis to determine the nature of the issue and whether the same event could potentially affect other vehicles. The early findings pointed towards a possible electrical short caused by contact between the 24V busbar and the metal fuse box. Meanwhile, on April 20, out of an abundance of caution, the vehicle customer identified as potentially affected, decided to ground the entire suspect fleet.

On April 24 GILLIG engineering confirmed the initial observation and determined the issue may be caused by a custom redesign of the low-voltage disconnect switch which may cause excessive preload and subsequent damage of the rubber insulation grommets of the fuse box.

On April 26 GILLIG completed safety analysis and confirmed the failure mode may potentially affect a limited population of vehicles owned by the customer initially identified.

On May 11 the GILLIG Safety Committee decided to file a formal safety recall with NHTSA.

As of May 16 2023, GILLIG is not aware of any other similar event nor injuries potentially related to this condition.
