Gillig LOW Floor Recall 24V959: Loose compressor cable may not trigger shock warning

NHTSA campaign 24V959, reported December 20, 2024, 332 vehicles potentially affected.

What this recall means for you

Certain 2023-2024 Gillig Low Floor transit buses have a high voltage electric air compressor that may not be connected to the High Voltage Interlock Loop (HVIL). Because of this, the system cannot detect a loose or disconnected compressor power cable, so the driver may not be alerted to the problem.

A failure to alert the operator to a power cable issue can increase the risk of injury from electrical shock.

An authorized Gillig dealer will install an additional electrical harness that extends the HVIL loop to the air compressor. The repair is free of charge. Owners were notified by mail on February 12, 2025, and can contact GILLIG customer service at 1-800-735-1500. You can also check your vehicle identification number (VIN) for open recalls.
